Jump Start Grasses Growing Early in Cold Spring Weather
Ornamental Grasses can reach knee high in Zone 5a by May, with most blooming by the end of August. I would like to jump start a few stands in hopes of enjoying blooms earlier in the season.
I have considered Water Walls, Solar Caps, Floating Row Covers, and Black Plastic to warm the air and immediate soil surface in the early Spring around April. I have considered watering with warm water to penetrate and deeply warm the roots.
Has anyone been successful at forcing ornamental grass to sprout up earlier or bloom sooner?
