Fast Crop Fall Transplanting Schedule • Allows a later-than-normal start for a natural season program. • The key to a fast crop is to not inhibit the growth by stressing the plant in any way. Do not pinch. • Flowering will generally occur 4 to 7 days later than a June-planted crop. POT SIZE PLANTS PER POT (PPP) TRANSPLANT DATE
