My hydrangea will not flower.- Master Gardener RSVP.?

I moved into a home where the hygrangea was already established. I live in zone 7b. The garden soil has been amended with organic compost down to 1 1/2 feet, and there is a 2" red cedar mulch covering. All the other flowers are doing quite well (snapdragons, white salvia, impatients, paeony bushes, and celosia). The hydrangea is quite healthy, but has not flowered in 2 years. I do not prune, since leaves produce on old wood. I fertilize 2x per year, but not the hydrangea. I removed a paeony bush 2 years ago, but I was careful not to disturb the hydrangea root system (although I cannot be 100% sure).





I have my Horticulture certificate and Master's liscence in Florida, but living in PA is totally foreign to me. Could someone please help?

well we have a hydrangea that flowers all the time - its in semi sun position... i prune back slightly, and water every second day during summer. Its not in special soil. maybe your compost is too strong and doesnt agree with it, or its not in the right position. I use slow break down fertiliser pellets (called rapid raiser in australia not sure if u have that) occasionally maybe twice a year.Dont know if this helps or not.

This is the North Carolina website that might help you out. Hydrangea's are temperamental plants, but beautiful when they bloom. I've killed three so far! Endless Summer is the best for our area, but I'm in Zone 5. This sight tells what's best for your area. Good Luckl!
Reply:Many of the florist-sold, potted hydrangeas aren't flower bud hardy. This is because they bloom on last years growth, and the flower buds die during the winter. You'll love 'Endless Summer', it blooms on both old and new wood.
Reply:Mine flowered this is it's first year. I use miracle shake ans feed and Epsom's. I also water it either daily on hot days or every other day on cooler days. Mine is also in mostly sun and no special soil. My zone hardiness is 5 and I haven't had a problem.


In fact where I am at the soil is poor dry and crumbly.
