gladiolus bulbs

Question

My glad bulbs have bloomed. Now do I have to dig them up after the frost or can I leave them in the ground? When I left them in the ground, they come up, but have not bloomed. We are in zone 9 in central Florida. Or do I have to buy new bulbs each year?

Answer 1

You should not need to dig them up where you are. You need to make sure that you leave the foliage in place after they bloom. They build up energy from the leaves for the next blooming cycle. Also, try giving them some bone meal which will help boost the phosphorous they need to bloom.
