I would like to know if you had root rot in butterfly bushes or perennials this year
due to so much rain and then hot sun and humidity ?


I lost 7 butterfly bushes to disease or root rot...
I put the liquid plant food to them 5 times as suggested and that did not bring them out
I never watered if it rained ..and it rained 3 times a week most of the summer...


The flower bed does not sit in water or a bog

the plants had play sand and black good dirt in the holes

I just feel sad and frustrated and not sure of myself after gardening
for 18 years with flowers...

Group hug Sorry no help here Sheri. Sad to hear about your butterfly bushes. I love them but they do not survive our winters for me. They may live through 1 or 2 winters and then die.

Hi Sheri,

Butterfly bushes do great around here because the ground is very gritty and it doesn't rain. I know that nurseries, Ag Depts, or arborists in some areas were telling people to fertilize if their plants started looking bad.

That's good advice but also bad advice. A plant that is losing its roots to lack of nutrients needs fertilizer to survive. I'm sure all that rain washed out a lot of nutrients so it seemed like a good plan.

But... if a plant is losing its roots because of too much water, fertilizer will just help it along to a quicker death. Whoever thought that fertilizer would solve all your problems did all of you a real disservice.

When you replant your Butterfly bushes, don't use play sand. The grains of sand are too small and when it gets wet, tends to pack down into concrete.

What does your native soil look like? If you need to add grit, something like decomposing granite would work a lot better. This is sometimes sold as chicken grit at the feed store (make sure its not ground oyster shell).

Which "butterfly bushes" do you have? Several plants share this nickname.

..."the plants had play sand and black good dirt in the holes..."
This sounds suspicious.

Most years, most plants do well. But there is that bad year when they don't. I'm sorry to here of your's. But I think we are going to get more of them.

"Climate change" means that weather gets less predictable and more variable as the atmosphere slowly warms.

Here in Zone 7 MD, we had less than average rain 9 of the 12 last months. But so much in July and August (not only unusual but bizarre) AND unusually cool, everything is a bit out of pattern here. My Saucer Magnolia trees that were so damaged from a warm Winter and late-frost Spring, have been flowering off and on all month.

My warm weather veggies all stalled, I got a few Spring Bulb daff shoots up, and the tomatoes were mostly soft from excess rain. The cucumbers are only now fruiting. The beans loved it though.

The last time I got this much rain in a month we were edged by a hurricane.

Oops, sorry, meant to mention that the butterfly bushes and other shrubs and plants are doing fine. There IS an advantage to having a sloping yard. Mostly not, but in this rainy time, yes.

I almost never fertilize except to add compost once in a while. We've had a ton of rain but also had a few dry spells. I only water when it hasn't rained for a week or more and then only water the plants that beg for water.

That being said, I have planted 3 butterfly bushes /Buddleja, they failed to thrive. No root rot; just failed to thrive. Perhaps they are plants that are either too fussy or would prefer to be neglected?? Shrug!

I've read that nematodes can be a real problem for Buddleja in the south. You may want to do some research online and, also, see if the roots of your dead plants have galls. Just another possibility to consider. Shrug!

Yes, lost many TB iris to rot this summer. Very sad and frustrating since usually they thrive here, but we've had lots of rain this summer. My buddleia have not suffered though.

I need to take a pic of the B. davidii in my MIL's yard. I started a tiny twig as a cutting and put it there a few yrs ago. It's much taller than a person and about as big around as a van... The heat & humidity of AL/FL border area seems to make it thrive.

I've seen SO MANY pics of B. japonica being called B. davidii, which might be a factor in some locations, though B. japonica was so happy in this climate that I had to evict it completely. It's a suckering entity that also makes & drops seeds, and was making an unruly and increasingly large patch, with seedlings showing up nearby.

In my limited experience with named cultivars in general, they often lack the vitality of the plain species. But the seedless B. davidii cultivar that I've had for almost 30 yrs is one of the most hearty entities I've encountered.
