How to Plant Gladiolus Bulbs in Florida

Gladiolus are a bright and beautiful flower. They are grown from a bulb, but, unlike many popular bulb flowers, gladiolus bulbs need to be planted in spring. Because the climate in Florida is warm and moist, gladiolus and other bulb flowers can easily grow and thrive. The key to growing gladiolus is to pick a location that receives full sun or only partial shade. They can tolerate many soils, but will do best in a well-drained soil with a pH between 6.5 and 6.8.


Prepare the bed for planting by rototilling or plowing the soil with a shovel or spade. Thoroughly loosen the top 12 inches of soil.

Add mulch or other organic material to the soil, mixing it well with the existing soil.

Dig a hole 4 to 6 inches deep.

Place gladiolus bulb in hole.

Firmly pack down soil around the bulb so no air bubbles are left.

Dig another hole at least 4 inches away from the first.

Repeat steps 4 to 6 with remaining bulbs.

Thoroughly water all the newly planted bulbs immediately after planting so they can begin to establish a root system.

Plant Gladiolus Bulbs?

Gladiolus flowers are perennials that stand tall and beautiful. After purchasing your bulbs, plant at the peak time so your flowers will grow and thrive. Plant your bulbs 6 inches deep in your garden and cover it halfway with loose soil. Depending on the size of the bulb, plant them between 2 and 7 inches apart. The larger the bulb, the farther apart they should be planted. The gladiolus thrives best in sandy soil and if you do not live in an area where sand is part of the soil, you must mix it into the dirt.


Once foliage begins to grow, water the flowers every few days (if there is no rain in the forecast). Weeds can choke out gladiolus, so regularly check for and remove any invasive plants in the gladiolus bed. If your plants grow so big and tall that they begin to droop or fall, stake them so they remain upright. If your soil is not nutrient rich, you may want to add a 5-10-5 fertilizer immediately after planting.
