- 7 days after transplanting, apply 15-0-0 N:P:K / 150 ppmN once a week. (2.2 Pounds per 26.4 Gallons of water)

- 3 weeks after transplanting, apply 8-24-24 N:P:K / 80 ppmN once a week. (2.2 Pounds per 26.4 Gallons of water) to promote bud formation

 

Micro Nutrient Application :

- Spray Micro Nutrients once a week.

- Calcium (Ca), Boron (B), Magnesium (Mg) and Zinc (Zn) are recommended to apply from budding stage until the middle of the harvesting period.

 

Calcium (Ca) Deficiency:

When faced with a Calcium deficiency, symptoms develop rapidly on new and young, unfolding leaftlets. Spots of black necrosis will turn brown. This effect starts on young leaves, at the base, and spreads towards the tip. Severe necrosis develops on the growing points, causing the shoot tips to die. Necrotic symptoms also develop on buds and pedicels, causing the buds to collapse.

 Boron (B) Deficiency:

Boron deficiency symptoms first appear as glossy, darker green foliage. The basal leaflets of young leaves develop a narrow needle-like appearance. The plant's growth is stunted due to internodes.

 Magnesium (Mg) Deficiency:

Magnesium deficiency symptoms initially develop on the older leaves as a dark discoloration on the leaflet margins and quickly turn to an interveinal chlorosis. Irregular necrotic patches follow on the leaflet margins of mature leaves. The plant size and weight will not be reduced.

 Zinc (Zn) Deficiency:

The development of chlorosis on the growing tip is the first symptom of zinc deficiency. Flowering is severely affected as the buds will stop evolving. Chlorosis spreads from the upper part of the plants to the lower leaves, beginning along the leaflet margins of the lower leaves. As symptoms progress, chlorosis on older leaves becomes intense, taking on a veinal pattern. Necrosis begins at the leaflet tips.

Insect Prevention

Place Yellow and Blue insect sticky traps around Marigold beds.
