Hydrangeas are turning brown

Mary Sullivan on Jul 17, 2013Is it getting enough acid? I know that you can stick a tablespoon of Epsom Salts in a gallon of water to raise the acidity of the soil. I am looking forward to seeing what more expert folks have to say.1 marked as helpful Reply

Town Pride Lawn Service on Jul 18, 2013I suspect a blossom blight disease due to favorable weather conditions for many fungus pathogens.Helpful Reply

Beverly on Jul 18, 2013I'm having the same problem--and same weather. Anxious to review all the responses. I will try the Epsom salts. Is it too late for a fungicide?Helpful Reply

Douglas Hunt on Jul 18, 2013Hot and wet weather could definitely bring on a fungus issue. @360 Sod (Donna Dixson) may have some suggestions.Helpful Reply

360 Sod (Donna Dixson) on Jul 18, 2013I have also noticed that conditions are ripe for thrips as well as fungus related diseases. To find thrips, take the bloom in one hand and sharply tap the blooms into the palm of your hand. Thrips look are tiny critters but you can see them and feel them crawling on your hand. You can find chemicals to treat them in any garden supply department or store. I think the smartest treatment would be something like the Bayer 3 in 1, to control fungus and critters. I will head out to the greenhouse in a bit to check mine for thrips. I did have some on some roses about a month ago.Helpful Reply

Amy Merriam on Jul 19, 2013Hydrangea blossoms do this when they are getting too much hot sun. Hydrangeas prefer more shade than sun. It won't hurt them..it just makes them look bad. Can you rig up some kind of shade "structure" during the hottest times of day..just to get them through the worst of this summer? And then maybe think about moving them...or planting something next to them that will block the worst of the hot sun.Helpful Reply

Sue Weiker on Jul 19, 2013We're having a severly hot and humid summer with a lot of rain also, and mine is doing the same thing. My hydrangea is in mostly shade and has never been anything but prolific in floral display and beautiful. They have never done this before. I am gonna try donna's advice. Thanks much donna and Doug, bothHelpful Reply

Rosalie M on Jul 19, 2013I haven't had much luck with hydrangea and finally got one growing and blooming this season. My plant did the same thing. I dead-headed the bush. Is that something I should not have done? The instructions with my plant said to: "plant in full sun". How can one really know what to do. Incidentally, same weather conditions in PA...rain/hot, hot, hot.Helpful Reply

Susan Duff on Jul 19, 2013You've described my hydrangeas as well - half eaten leaves and brown/black leaves. I wondered about cutting them back to just a few inches? I began treating them with a 3 in 1 fungicide/insecticide/organic spray three evenings ago. The directions indicate to treat consecutively for 7-14 days. I just planted them early this summer and they were very healthy at the time. Cut them back or leave them alone?Helpful Reply

360 Sod (Donna Dixson) on Jul 19, 2013well I did not find any thrips on the Hydrangeas I check yesterday afternoon and I do have them in control on my roses, thank goodness. @Susan Duff, not being sure what type you have, I would err on the side of caution and not cut them back yet.Helpful Reply

Decor&Dine on Jul 19, 2013No thrips on mine either checked this morning and mine are in partial shade but I think it is the very very hot weather that we have been having. Thank to all for your responses.Helpful Reply

Natalie Scarberry on Jul 19, 2013I agree with Amy Merriam. It's too much heat and sun. At least that's what it is when it happens to mine here in Texas.Helpful Reply

Trish Ross on Jul 20, 2013I live in Alabama where there is 'heat' all summer long. I have also noticed more beautiful Hydrangeas here than when I lived in Michigan. We have several types such as cone shaped blossoms and puff ball blossoms. The 'natural' colors depend on soil and landscape. I have noticed them growing on mountain sides in shaded areas where they begin with white/brown blossoms. Cultivated ones in yards with beautiful long white cones of blossoms that 'droop' in a beautifully shaped bush that grow to 8-10 feet in height. There are beautiful blues and beautiful pinks that are always in 'puff ball' blossoms. Color depends on soil ph. They seem to grow well in any type of sun/shade as long as they get at least 6 hours of sun a day. They all eventually turn brownish before they begin that journey to sleep but the blossoms remain beautifully intact. Have you ever seen dried hydrangeas? They never have any color...just a beautiful brown tone.Helpful Reply

Susan Stambaugh on Jul 22, 2013I live in Pennsylvania and have grown beautiful Hydrangeas for years. This year they just look terrible. We have had 2 spells of 95 or above temps lasting for days only going down to around 70-75 at night.It actually hit 102 on my thermometer the other day and the humidity is oppressive. After about 5 days of this weather they just started to "burn" as I call it. Everything here is showing heat exhaustion including the plants.I just keep watering daily and hope for the best. Even my beans aren't growing as well and they are usually my best growers.Helpful Reply
