How to Plant Iris Bulbs in Florida

Florida's warmth and humidity creates a great climate for bulb flowers. Irises are among the many bulb flowers that will thrive in much of Florida. The weather in northern Florida is not always suitable for irises, however. Another good thing about growing irises is that they can be planted in either spring or fall. Because of their size and other features, they are well-suited for either stand-alone flowerbeds or as a border in a larger flowerbed or garden. The many species of irises produce flowers of many colors, so you can choose a color of your liking.

Till the ground in the area where the bulbs will be planted using either a rototiller or a shovel.

Mix in peat, compost or another organic material, adding 1 pound to 1.5 pounds for every 100 square feet.

Level off the soil so there is a flat ground in which to plant bulbs.

Water the soil lightly so it retains moisture for planting.

Dig a 1-inch deep hole.

Place the bulb in the hole with the points facing up.

Cover the bulb with soil, packing it down firmly so there are no air bubbles.

Water the bulb thoroughly so it can begin to take root.


Irises grow best in a sunny location and in a well-drained soil. If you do not have well-draining soil, consider growing them in a raised bed. When planting multiple iris bulbs, they should be planted 8 inches apart. If weeds are a concern in your iris bed, add a 2-inch layer of mulch after planting. Irises will grow best if the soil is kept moist, so be sure to water them during dry spells.
