# My Gladiolus Won't Flower
-
Quality Corms
-
Beautiful blooms come from high quality corms. Glads sprout from enlarged bulb-type stems called corms. The shape of the corms is critical. Choose full, round corms over large, flat, thin ones. Select corms that are at least 3/4 inch in diameter for best bloom.
Sunlight
-
Plant gladiolus in full sun for best flower display. Longer and bigger blooms will result when gladiolus grow in full sun. Quality corms will flower in the shade but will not be as profuse without adequate sunlight. Glads planted in full sun will accumulate more energy for next year than those placed in the shade.
Soil
-
Plant glads in well-drained, loamy soil. Plant glads in loamy soil with excellent drainage. Augment clay soil with organic matter such as peat-moss or well-aged manure. Wet-feet inhibits growth and may prevent bloom. Use raised beds to avoid water damage.
The Nitrogen Factor
-
Glads planted too close to a fertilized lawn will not bloom. Flower beds close to lawn areas can inadvertently receive too much Nitrogen from lawn fertilizer. Excess nitrogen will allow gladiolus to produce leaves but no flowers. Be sure that glads are not planted close to fertilized lawn areas.
