I have 10 alliums planted in my garden. They all produced lovely long stemmed flowers last year.This year only one had a flower. Should I feed them so that they will flower next year? What can I feed them with? Only the leaves of the other nine came up.Thanks for your help with the angel trumpets!

Alliums can be difficult to grow long term under home garden conditions and tend to dwindle away in locations where the soil is heavy or poorly drained. They need full sun and a well drained spot. It is a good sign that they survived a second winter. The most important thing you can do to try to get them to rebloom is to encourage the foliage to grow and thrive. Then leave the foliage on the plant until it is completely dried up. Topdress with compost in late winter to early spring, and also apply a granular fertilizer such as 10-10-10 per the label directions when they first begin to grow in the spring. Check the soil pH, it should be between 6 and 7 so in your area you may need to add some lime to adjust it to that. If you planted extremely large bulbs, they may have divided. If that has happened, it will take another year or so for the split bulbs to reach flowering size again. I hope this helps! Good luck with your angel trumpets, too!!
