Annual Practices for Perennial Crops:

Fully Controlled Greenhouse.
Sowing Method: Direct Seeding.
3 seeds are sown per container (10 cu inch Ray leach tubes). Seeds are surface sown and planted 2 times the diameter of seed to depth.
Media used is standard potting mix of peat moss, fir bark, perlite, and sand.
Containers are are watered in with an automatic irrigation system.
Seeds are sown on June 1st.
% Germination:65%
