1.9.1 DESERT TREES

PRUNING

Pruning a tree in desert climates, like Desert Willows, Palo Verde, or Africans, requires specific care due to the harsh growing conditions. These trees are adapted to thrive in dry environments, so proper pruning is essential for their health and appearance. Here are the general steps to prune a desert tree effectively.

1. Inspect the Tree, look for any dead, diseased, or broken branches that should be removed first. Removing dead wood will prevent pests and diseases from taking hold. Identify branches that rub against each other or cross over one another. These can cause wounds that allow pests or diseases to enter the tree. You should also evaluate the overall structure of the tree and make note of areas that may need thinning or shaping to promote better air circulation and sunlight penetration.

2. Prune for Health, cut away dead, damaged, or diseased branches, cutting them back to healthy tissue. This helps prevent rot and disease from spreading to healthy parts of the tree. When removing dead or diseased wood, always cut back to the base of the branch or to a healthy branch. Avoid leaving stubs, as they can become entry points for pests and diseases.

3. Prune for Shape and Size, desert trees often have a natural, irregular shape. Prune back any long or leggy growth to maintain a balanced and attractive appearance. Trim branches that are growing inwards or towards the center of the tree to help maintain an open, airy structure. If the tree has outgrown its space or is becoming too large, prune to control its height and width. Remove any branches that are crowding pathways or structures. Keep the cuts gradual, never removing more than a third of the tree at a time to avoid stress.

4. Remove Suckers and Water Sprouts, suckers are shoots that grow from the base of the tree or from the roots. These should be removed to maintain the tree’s shape and prevent them from drawing energy away from the main tree. These fast-growing, vertical shoots typically form after heavy pruning. If left unchecked, water sprouts can weaken the tree's overall structure.

5. Thinning for Airflow, prune away any small or weak branches inside the tree to improve airflow and light penetration. This is especially important for desert trees, as it helps to prevent fungal diseases and allows for better photosynthesis. While thinning is important, don’t overdo it. Desert trees need their leaves to survive in dry conditions, and too much thinning can cause stress and reduce the tree's ability to photosynthesize effectively.

IMPORTANT THINGS TO HAVE IN MIND WHILE PRUNING

When pruning a tree, it is important to use the proper cutting tools such as hand shears, loppers, or pruners, depending on the size of the branch being removed. Additionally, always angle cuts away from the stem to prevent water from pooling and causing decay. For larger limbs, it is often best to make several smaller cuts rather than one large cut to avoid damaging the tree. If two branches are rubbing against each other, cut one back to reduce friction and prevent wounds that can invite disease or pests. Also, remove any branches that cross or grow toward the center of the tree, which can crowd the tree’s interior and reduce airflow.

When managing height and width, the goal is to maintain a natural appearance and balanced shape. This can be achieved by selectively trimming branches that are too long or growing too closely together.

It is important not to remove more than one-third of the tree’s branches at any time, as this can stress the tree and cause long-term damage. If pruning multiple branches, ensure they are spaced evenly to preserve the overall shape.

SECTION 1

PERFORMANCE WORK STATEMENT

Lastly, always make cuts just above a bud or leaf node to encourage healthy new growth in the desired direction. By following these tips, you can keep your tree healthy, well-shaped, and thriving for years to come.

For flowering desert trees like Desert Willow, prune spent flowers and seed pods to prevent the tree from expending too much energy on seed production. This will also help the tree look tidy and promote further blooming.

1.9.2 PALM TREES

Maintain palms always clean and in good condition. Trim those whenever is necessary or requested by the COR. This task implies height work which must be considered in the safety plan mentioned above.

PRUNING

1. Assess Possible Hazardous Growth, look at the overall shape of the Bismarck palm's canopy of fanlike fronds. It naturally becomes a rounded mass of leaves, even extending fronds horizontally and to the ground in young plants that lack a trunk or have a short one. Note if any fronds pose a hazard such as blocking a walkway, rubbing into a building facade or encroaching upon another prized plant in the garden.

2. Remove Hazardous or Sagging Fronds, remove fronds that pose a hazard or are already dried or light brown in color and sagging along the trunk. According to the University of Florida, there is no reason to remove healthy fronds or those that grow horizontally or upward angled in the canopy. In fact, removing healthy palm fronds stresses the plant and slows its growth and production of food.

3. Use a Pruning Saw, saw into the base of the frond with a pruning saw about 6 inches from the trunk. Grasp the stem petiole of the Bismarck palm frond with your spare hand and balance it as you cut; it is large, heavy and cumbersome. As you penetrate the stem with the saw, be prepared to support more weight of the dropping frond. Balance the frond as you saw to prevent it from tearing at the base and to help guide its fall.

4. Remove the Pruned Fronds, lift the cut frond away from the palm or direct its drop to the ground after the pruning cut severs it.

5. Trim Flower Stalks, to prune other parts of the palm tree in early summer, such as the flower stalks that grow from the cluster of frond bases. Bismarck palms are either male or female based on their flowers; only pollinated female palms yield the blue-green fruits that ripen to black. Removing flower stalks improves the visual "cleanness" of the palm in some people's eyes. Keeping the flower stalks is fine, too, but they will dry to brown in fall and not look attractive.

IMPORTANT THINGS TO HAVE IN MIND WHILE PRUNING

Always prioritize removing dead, yellowing, or brown fronds. These fronds no longer serve the tree and can attract pests or diseases. In addition, palm trees rely on their healthy, green fronds for photosynthesis and

SECTION 1

PERFORMANCE WORK STATEMENT

energy production. Only remove fronds that are completely dead or diseased. Remember that when removing fronds, make sure to cut them as close to the trunk as possible without damaging the trunk itself.

The central leader (the topmost growing point) should never be pruned. It is crucial for the palm’s growth. Cutting this part can stunt the tree’s growth and may kill it.

1.9.3 SMALLER PLANTS (SHRUBS/GROUND-COVERS)

1.9.3.1 JUSTICIA CALIFORNICA (CHUPAROSA)

Pruning a Justicia californica (also known as Chuparosa or California Fuchsia) is a straightforward process that helps maintain the health, shape, and appearance of the plant. This shrub is native to desert regions and thrives in dry conditions, so proper pruning can encourage vigorous growth and improve flowering.

1. Remove Dead or Damaged Growth, look for any dead, damaged, or diseased stems and remove them at their base. This will help the plant focus energy on healthy growth and prevent the spread of disease.

2. Identify Spent Blooms, cut back spent blooms to encourage the plant to continue blooming or to prevent the plant from expending energy on seed production.

3. Shape the Plant, maintain a compact, bushy shape, prune back leggy growth, cutting just above a set of leaves or buds. This will encourage the plant to grow more densely and prevent it from becoming too spindly. If the plant has outgrown its space or become too large, you can trim back the stems to the desired size. Be cautious not to remove more than one-third of the plant's size in a single pruning session.

4. Cut Back to Promote New Growth, prune back to healthy nodes or leaves, especially if the plant has become too leggy. Cutting back to these points will stimulate fresh new growth in the spring, resulting in a more vibrant and fuller plant. Unless the plant is severely overgrown or needs rejuvenation, avoid cutting back too far to the ground. Justices californica can be pruned more drastically if it has become woody, but it is typically best to leave some structure.

5. Remove Spent Flowers and Seed Pods, After the flowering season, remove any spent flowers and seedpods. This will keep the plant looking tidy and may help to promote a second flowering in some cases. If you want to control where the plant blooms, you can selectively prune the stems where flowers appear, encouraging a uniform display.

1.9.3.2 BOUGAINVILLEAS

Bougainvillea are fast-growing, hardy plants that thrive in warm climates, and regular pruning helps to control their size and promote more flowers. Here are the steps to prune a Bougainvillea properly.

1. Inspect the Plant, start by removing any dead, diseased, or damaged branches. This helps the plant focus its energy on healthy growth and reduces the risk of pest infestation. In addition, check for any areas where the plant has become too thick or leggy and could use some thinning to improve airflow and sunlight penetration.

2. Prune for Shape and Size, Bougainvillea are often pruned to maintain a compact, bushy shape or to encourage them to climb if they are trained as vines. Cut back any long, leggy branches to a lateral branch or leaf node to encourage denser, more controlled growth. To control their size, prune back any overgrown or excessive branches, making sure not to remove too much at once. Remove no more than 1/3 of the plant at a time to avoid stress.

3. Encourage More Blooms, bougainvillea bloom on new growth, so pruning the plant will encourage the production of more flowers. After each bloom cycle, prune back the plant to encourage new growth where the flowers will appear. Cut the branches back to a healthy node (the point where a leaf or branch grows from the stem). This will encourage branching and lead to more blooms.

4. Remove Leggy or Overcrowded Growth, if Bougainvillea has become too dense, thin out the interior growth to allow sunlight and air to reach all parts of the plant. This also helps to reduce the risk of fungal diseases. Make sure to prune at an angle just above a bud or leaf node. This will help encourage new growth in the desired direction.

5. Prune Vines or Trailing bougainvillea, if Bougainvillea is growing as a vine, prune it back to encourage lateral growth along the support structure. You can remove longer stems or trim the tips of the branches to maintain its shape and encourage branching. For vines, regularly check that the plant is growing where you want it to, and redirect growth by pruning where necessary.

1.9.3.3 NOPALES

Pruning nopales (the pads of the prickly pear cactus) is an important practice to maintain the health, appearance, and productivity of the plant.

Pruning encourages the growth of new pads, removes damaged or diseased parts, and helps the plant retain a manageable size.

1. Inspect the Plant, start by looking for any pads that are dead, diseased, or damaged. These should be removed first to help prevent the spread of any infection. Examine the cactus for any pads that are too close together or growing in awkward directions. Pruning these will improve airflow and sunlight penetration, promoting better overall growth. Also, identify any pads that are growing too large or in unwanted directions, especially if the cactus is growing too wide or taking up more space than desired.

2. Prune the Nopales, use pruning shears or a sharp knife to cut away any dead or diseased pads at the base. Make clean, straight cuts as close to the main stem (or trunk) as possible. If the pad is dead or rotting, remove it entirely to prevent disease spread. To control the size and shape of the cactus, prune any pads that are overly large, growing in the wrong direction, or crowded. Make cuts just above the base of the pad, ensuring the remaining pad looks natural and balanced. When cutting pads for size or shape, try to make cuts that encourage new pads to grow in desirable locations. If you leave a flat cut, it may encourage new pads to grow from that spot.

3. Handling the Pruned Pads, always handle the cut pads carefully, using tongs or pincers to avoid direct contact with the spines. Use a towel or thick gloves to move them safely. After pruning, dispose of the cut pads away from the plant. In locations where the pads can root, replanting in the ground to propagate new plants is an option. Just ensure they are left to dry out for a few days to form a protective callus over the cut surface before planting.

4. Monitor for New Growth, pruning encourages new growth from the base of the cactus or where pads have been removed. If pruning for harvesting, start to see new, smaller pads grow from the main stem. After pruning, ensure the cactus is watered, especially if removing a large amount of growth. However, be careful not to overwater, as cacti are sensitive to excess moisture. Water lightly but consistently until the plant shows signs of new growth.

5. Pruning for Harvesting Nopales, if pruning the cactus to harvest nopales for cooking, choose mature pads (usually those that are about 6–8 inches long) and cut them off cleanly with a sharp knife. Leave the smaller, younger pads to grow for future harvesting. After harvesting the pads, make sure to leave enough healthy growth to ensure the plant continues to thrive and produce more pads in the future.

1.9.3.4 PENNISETUM SETACEUM (FOUNTAIN GRASS)

Fountain grass is a popular ornamental grass known for its graceful, arching stems and feathery flower heads. Pruning helps rejuvenate the plant and promotes lush new growth.

1. Remove Dead or Damaged Foliage, start by inspecting the grass for any dead, brown, or damaged foliage. These are best removed to keep the plant looking neat and healthy. If the plant is getting too large or out of shape, pruning will help control its size and maintain its natural arching form.

2. Cut Back Old Growth, cut the entire clump of grass back to about 4 to 6 inches above the ground. This allows for fresh growth while also removing the old, dry foliage that could hinder the plant’s new shoots. Make clean, sharp cuts to avoid damaging the plant and to ensure that new growth can easily emerge. Be careful not to cut into the crown of the plant (the base of the clump where the new growth emerges). Prune just above the crown to leave the healthy tissue intact.

3. Remove Dead or Diseased Foliage, as pruning, check for any signs of disease or pests, such as discolored or damaged leaves. Remove any affected foliage to improve plant health. If there are any damaged or broken stems, trim them back to the base to allow healthy growth.

4. Shape the Plant (If needed), to shape the grass or reduce its size, trim back any overly long or out-of-place stems to maintain a rounded, tidy appearance. For older, dense clumps, thinning out some of the older growth can help encourage fresh new shoots and improve air circulation.

1.9.4 LAWN CARE (SOD/BERMUDA GRASS)

Pruning sod (or turf grass) is not a common practice in the same way as pruning shrubs or trees. However, there are maintenance tasks that resemble pruning, such as mowing and edging, which are crucial for keeping your sod healthy and looking neat. Maintain turf in a healthy, growing condition by performing the following operation and other incidental work thereto.

1.9.4.1 GRASS CUTTING, EDGING, TRIMMING AND WEEDING

The Contractor shall maintain the height of turf grass between 2 and 3 inches (5-7.5 centimeters); shall edge all sidewalks, driveways, and curbs each time the adjacent grass is cut. However, shall always check the guidelines for your specific grass variety. The Contractor shall trim grass around trees, shrubs, cultivated areas, sprinkler heads, valves, fences, buildings, poles, and structures. The Contractor shall weed the grounds and gardens on a continuous basis to prevent the growth of weeds into lawn and landscapes.

The Contractor may use weed-killing chemicals (EPA approved) to prevent the growth of weeds to eliminate grass and weeds in the cracks and joints within or along sidewalks and curbs. The Contractor shall obtain approval of the COR for all applications of weed killers. The Contractor is responsible for all equipment and fuels needed to complete this task.

1.9.4.2 MOWING AND TRIMMING

Avoid Cutting Wet Grass: Avoid mowing sod when it's wet, as this can lead to clumping, uneven cuts, and stress on the grass.

1. Turf shall be mowed using a “reel type” mower, at least once every seven calendar days, it may be necessary to mow more often during periods of rapid growth or less during slow growth periods. Turf shall be mowed as otherwise necessary to maintain a neat, trim appearance. Rough cutting will not be permitted. Mowing schedules will be at the direction of Facilities Manager.

2. Mowing Height: Try to cut no more than 1/3 of the leaf length with each cut. Mowing height is to be measured with mower on a flat, paved surface. Mowing height for each site shall be confirmed with Facilities Manager.

3. Mowing shall be accomplished in such a manner so that no damage occurs to sculptures, trees, shrubs, perennials, signs, etc. Grass catching attachments shall be in place during mower operation. Sharp Blades: Ensure that the mower blades are sharp, as dull blades can tear the grass, causing it to turn brown or develop fungal diseases.

4. Clippings shall be immediately removed from any roadway, walkway, or parking area, curbing, drains, etc. after each mowing. Excessive clippings resulting from lush growth shall be removed from grass areas by the contractor after each mowing operation. Excessive clippings are typically defined as accumulated clippings that may inhibit the health of the underlying plants.

5. Trimming around trees, shrubs, utilities, signs, etc. shall be performed at each mowing using herbicides, hand labor, and/or machines. Trimming shall be done in such a manner as not to damage sculptures, trees, shrubs, signs, etc. Only Post approved herbicides may be used. Post will provide the herbicides recommendations to the Contractor.

1.9.4.3 EDGING

TURF: Trim all edges with every mowing. Grass along curbs and sidewalks shall be cut vertical with the turf side of the pavement and present an even height. Remove all debris, dirt and trimmings after each operation.

1.9.4.4 WEED CONTROL

Normally flower beds, lawns, and around trees and shrubs, will be weeded by hand or with a hoe. When herbicides are required, Contractor will notify a Consulate Building and Grounds representative. Only Post approved herbicides may be used. Post will provide the herbicides recommendations to the Contractor.

The preferred Anti-desiccant is “Wiltpruf,” current product appears to be Herbicide & not an anti-desiccant.

TURF: Pre-emergent herbicide shall be applied at the contractor’s discretion to control both annual and perennial grassy and broadleaf weeds in strict accordance with label directions. Only Post approved herbicides may be used. Post will provide the herbicides recommendations to the Contractor.

1.9.4.5 PAVED SURFACES

Use non-selective and/or pre-emergent herbicides as necessary for expansion joints and cracks in paved surfaces. It shall be the contractor’s responsibility to remove all annual grasses and weeds from expansion joints and cracks of hard surfaces once the grasses and weeds have been sprayed and died. Only Post approved herbicides may be used. Post will provide the herbicides recommendations to the Contractor.

1.9.4.6 TURF REPAIR AND RE-ESTABLISHMENT

The Contractor shall, whenever necessary, repair areas damaged by vehicular traffic, oil and gas, building repairs, and foot traffic. The damaged area shall be filled in and leveled and then seeded or sodded and maintained to conform to adjacent areas. Sod, labor and any other required materials shall be furnished by the Contractor at no additional expense to the Government up to the maximums defined in Sections below.

1.9.4.11 ORGANIC MULCH

Organic mulch is a layer of natural material, such as wood chips, leaves, straw, or grass clippings, placed on top of soil. It shall be used, when necessary, in coordination with the COR and without causing additional expenses. Here are some key properties and benefits of mulch.

Moisture Retention: Mulch helps soil retain moisture by reducing evaporation. This is crucial for plant health, especially in hot, dry climates.

Temperature Regulation: It insulates the soil, keeping it cooler in the summer and warmer in the winter.

Weed Suppression: Mulch creates a barrier that reduces the amount of sunlight reaching the soil, thereby inhibiting weed growth.

Soil Health: Organic mulch decomposes over time, adding nutrients to the soil and improving soil structure and fertility.

Erosion Control: Mulch helps prevent soil erosion by reducing the impact of rain and wind on the soil surface.

Aesthetic Appeal: It provides a neat, finished look to garden beds and landscapes.

On the rooftop, don’t use rock mulch because Carpobrotus, Malephoras, and Aptenias, which are present in those planters, need to breathe and make contact with the soil to expand and re-root. Rock mulch tends to be hotter on the surface and can interfere with the plants’ ability to re-root and spread. If mulch is necessary, a thin wood mulch is more suitable for ground-cover plants.

Organic mulch also provides several benefits for plants, including lowering soil temperatures, retaining moisture, reducing weed germination, minimizing dust pollution, and preventing soil erosion.

When natural precipitation is sufficient to fulfill this requirement, the Contractor may request the COR's permission to suspend watering to avoid too much water in the soil. In areas covered with drip irrigation, the Contractor will not attempt to maintain general water moisture penetration but will monitor moisture levels adjacent to the plants as well as general plant health and adjust watering schedules constantly to ensure these remain in proper, healthy condition. Any plant that is noticeably malnourished or dies because of an absence of adequate levels of water must be replaced at the Contractor’s expense.
