Wait until the flowering quince finishes flowering to apply a high-nitrogen fertilizer, such as 18-6-12. Use 1/2 lb. per 100 square feet and sprinkle it on the soil 3 inches from the base of the flowering quince. Use a rake to spread it out to the widest part of the plant.

Apply a 5-15-5 fertilizer at the rate listed on the fertilizer label in fall. This application should be applied in the same manner as the previous application and only to fruit-bearing flowering quince. The high phosphorus content of this formula helps the plant produce fruit. Water to a depth of 10 inches after applying.

Treat iron chlorosis with a foliar or soil application of chelated iron. Iron chlorosis is common in flowering quince when the soil is highly alkaline and is evidenced by yellow leaves, especially near the veins. Foliar iron chelate sprays require repeated applications over the growing season. Consult the label for a recommended schedule. Soil drenches cost more but only need to be applied once a year.
