FINISH PGRs
TECH TIPS
Covering seed is not necessary, but a light vermiculite coating will help maintain moisture levels in drier climates. Keep pelleted seed at moisture level 5 the first several days to help dissolve the pellet. Providing long days in the plug stage will reduce overall time to flower. Low boron levels can induce tip abortion. Spraying an uneven plug tray with B-Nine ® WSG at 1,500 ppm may help even the growth in the tray.
It is best to be proactive in applying PGRs on Petunias. Anticipate changes in weather and other conditions that can cause plant stretch and apply PGRs before plant stretch begins. Petunias respond well to B-Nine ® WSG sprays at 2,500–3,500 ppm. Do not apply B-Nine ® WSG after bud formation or flowers may reduce in size and/or become distorted. Bonzi ® drenches at 1–2 ppm during later stages in the crop reduces stretch and will not affect flowering as much as B-Nine ® WSG.

It is best to be proactive in applying plant growth regulators (PGRs) on Petunias. Anticipate changes in weather or other conditions that can cause plant stretch and apply PGRs before plant stretch begins. Petunias respond well to B-Nine ® WSG sprays at 2,500–3,500 ppm.
