I think a lot of people have questions about fertilizing, so here is a mini-guide that I have taken off the net that can probably help out. It only concerns N-P-K.

Main uses of the plant:

*Nitrogen promotes leaf growth. Use on hedges, grass, shade trees and other foliage plants. (10-5-5 or 20-10-10)

*Phosphorus promotes flowering; use a low nitrogen-high phosphorus fertilizer. (5-10-10 or 10-20-20) Use on perennials and flowering shrubs.

*Potassium promotes stronger stems and vivid colors. (5-10-10 or 10-20-20)

N-P-K Deficiencies Signs
Lack of:
Nitrogen -- Light green to yellow appearance of leaves, especially older leaves; stunted growth; poor fruit development.

Phosphorus -- Leaves may develop purple coloration; stunted plant growth and delay in plant development.

Potassium -- Older leaves turn yellow initially around margins and die; enlarged veins; irregular fruit development.

Hope this helps.
