Iris

IRIS

Where to Plant
Plant in an area that receives full or half day sun.

Soil Preparation
When planting an individual plant, use the following:

• 1/4 cu. ft. Omni Organo Soil
• 3/4 cup Soil Sulfur
• 3 tbsp. Osmocote Slow-Release Fertilizer

When planting beds, use the following (per 100 sq. ft.):

• 12 bags of 1 1/2 cu. ft. Omni Organo Soil
• 2 lbs. Soil Sulfur
• 5 lbs. El Toro Flower and Vegetable Food

Fertilize

Feed before bloom (February) and after bloom (April/May) with the following:

• 3 lbs. El Toro Flower and Vegetable Food
• 2 lbs. Triple Super Phophate per 100 sq. ft.

Dividing

Iris varieties differ in their growth rate, so a clump should be divided when it becomes too crowded in the fall (September/October). This needs to be done early for some; others can go for three years. Usually the best bloom is in the second year of a clump.
