PLANTING NOTES:

[1] HARVEST WILLOWS WHEN PLANTS ARE DORMANT (BETWEEN NOVEMBER AND MARCH); INSTALL IMMEDIATELY

AFTER HARVEST. CUTTINGS SHALL BE MIN. 3/4" DIA. AND 3 TO 5 FT LONG.

[2] CAREFULLY TRIM ALL BRANCHES WITHOUT DAMAGING BARK; SOAK STAKES FOR 24 HOURS MIN PRIOR TO

INSTALLATION.

[3] USE HEALTHY, STRAIGHT, LIVE STEMS AT LEAST ONE YEAR OLD. CUT OFF APEX AND FLOWERING PARTS (TOP

FOOT) OF THE STEM. MAKE CLEAN CUTS AND DO NOT DAMAGE STAKES OR SPLIT ENDS.

[4] CREATE A PILOT HOLE FOR EACH STAKE THAT IS PERPENDICULAR TO THE SURFACE OF THE BANK; THE HOLE

SHOULD BE TWICE THE DIAMETER OF THE WILLOW STAKE AND ROUGHLY ¾ THE LENGTH OF THE STAKE, AND

EXTEND DOWN INTO THE PERMANENT WATER TABLE

[5] PLANT STAKES THROUGH EROSION CONTROL FABRIC AT A DENSITY OF APPX TWO TO FOUR CUTTINGS PER

SQUARE YARD; VARY SPACING TO ENSURE RANDOM LAYOUT.

[6] BACKFILL PILOT HOLE WITH NATIVE SOIL AND WATER SLURRY TO ELIMINATE AIR POCKETS.

[7] KEEP MULCH AWAY FROM THE BASE OF THE PLANT STEM.

[8] SEED ALL DISTURBED AREAS WITH NATIVE GRASS MIX.
