One of my potted black & blues suddenly has a problem. The plant will look healthy and perky first thing in the morning, but when the sun hits it two of its stems quickly go limp. The stems are not broken and appear normal otherwise. This problem did not exist until the last few days. The only other notable thing about this plant is it was the last black & blue to be planted, so two weeks ago this one only had some tiny greet shoots while the others were already growing well, but it is growing the fastest of them all and has quickly become larger than the others. I'm not sure why. The two in-ground and two potted black & blues have all received two doses of half-strength 24-8-16 fertilizer this month. Any thoughts about limp stems or high growth rate?

This is what it looked like only one week ago. One of my in-ground black & blues had a solid head start on this potted one, but the in-ground one is still only about the size of the one in this photo.

Dan,

With the amount of growth, you should be getting just about as much root growth - and all those roots will need a lot more water.

I've been keeping the potted plants watered pretty well because they have been drying out fairly quickly. The potted b&b that has the limp stems when in the sun is quite moist this morning and that did not help any.

If the stems continue to go limp in a few days I may just have to cut them off and hope no other stems do the same.

I think Nan nailed it (again). The leaves look nice and green so it's not a nutrient problem. Water more and it should be better. Especially since you say once the sun hits it for a couple of hours that it happens, that's a dead give away to me.

OK, I see Dan posted while I was typing, so, maybe if you have very good drainage in the pots you might think about flushing the roots and let it drain real good. There might be a salt build up around some of the roots and causing them not to be able to uptake the moisture fast enough in the sun.

Pete, the stems go limp almost immediately when the sun hits the plant. The obvious first guess is lack of water, so I gave it a real good soaking yesterday, but it has had no effect on the limpness.

My first thought would also be lack of water. I believe I might try moving it into some partial shade for awhile till it develops a better root system.

since it is in a pot I would try moving it to a shadier location for a few days. It does seem like that one section may be drying out too quickly or the stem may be partially severed from the rest of the plant below the soil surface and not getting enough moisture to the stem

I've had the same problem with one of my Bee Balms. Just a couple of wilted stems and these plants have been in my flower bed since early spring. Also not lack of water. Maybe there is a slug or something in the dirt eating on the roots?

I'm wondering about something. The b&b with the badly wilting stem(which had to be cut off because it was too far gone) is one of the three b&bs that were overwintered in a cool basement with only some soil left on the clump of tubers/roots. When I replanted them 2-3 weeks ago I don't think I did a good job filling in the area under the plants' crowns with soil/potting mix. I obviously pushed soil/mix up against the plant, but it's quite possible there are some air pockets under the crowns. Could this have anything to do with what's going on? I think my wilting issue may be more extensive than just the one plant. The other two overwintered plants in the ground were also beginning to wilt and flop somewhat late this morning, despite the fact that I soaked them just yesterday and the weather isn't exactly scorching. It was 50 degrees this morning and still only in the 70s with bright sun. I'm beginning to worry that all of my overwintered b&bs are going to crap out on me.

The wilted stem plant in the pot perked right up when I put it back in the shade(except the bad stem). I just soaked the plant yesterday, and the mix is still reasonably moist, but the entire plant just seems to flop in the sun. The stems become very flexible and can't seem to properly support the weight of the foliage.

Dan that could be part of the problem. Also, since these are plant that were brought inside to overwinter could it be possible that they needed more hardening off time before going into direct sun?
