SEED FINISHING

FINISH PGRs

TECH TIPS

B-Nine ® WSG at 2,500–5,000 ppm or A-Rest ® at 1–3 ppm are effective if needed. Under long day conditions leaves will be larger so more frequent PGR applications may be necessary.

It is critical to not plant the plug too deep so as to bury the crown. Buried crowns can lead to hard, distorted growth or crown rot. Space plants on time so the leaves from one plant will not cover the center of another; shading the crown will delay flowering.

FINISH PGRs

TECH TIPS

B-Nine ® WSG at 2,500 ppm and Cycocel ® at 800 ppm two weeks after transplant is highly effective for reducing height and producing a compact, well-branched plant. In warmer conditions, a second application is beneficial.

Avoid drying the media too much since this can cause premature flower bud abortion. Grow under high light levels for top quality. Leaves may show chlorosis if plants are grown too cool.

FINISH PGRs

TECH TIPS

Responsive to B-Nine ® WSG, Bonzi ® , and Sumagic ® .

Use a calcium-based fertilizer and feed once a week at most to avoid soft growth and stretching of plants. Do not let plants go into the night with wet foliage or tip abortion may occur, especially during early stages of growth. Downward cupping or twisting of immature leaves may be caused by overuse of plant growth regulators (PGRs). It is better to use less water and fertilizer than PGRs to control growth. Preventive fungicide applications for foliar and root disease are recommended, especially in high humidity environments. Subdue Maxx ® , Mural ® , Micora ® , and Segovis ® fungicides can be used in a rotation program to control the common disease problems of Impatiens.
