Hello, I have been very successful raising large Milkweed in my garden...perhaps a little too successful! The plants are huge and gradually spreading. That is OK, in my informal setting I can let them sprawl. My problem is that I also have a clump of orange butterfly weed about 8 feet away from the main planting area of the bigger milkweed. They are still not very large and I fear the big plants will eventually choke them out. Can butterfly weed be transplanted after it is established? — Thank you
Butterfly weed has a long taproot and it doesn't transplant well. (Asclepias tuberosa) You could install a root barrier in the ground between the two so it can't cross over. You can buy them in metal or plastic at garden supply stores. It will take some deep digging, about 18 inches, to insert them. Leave about an inch above ground so the roots don't try to jump over.

my butterfly bush has new foliage but not producing flower buds.
It would be fine to prune it now. Here are two articles that should help:

About 3 weeks ago, We planted 2 butterfly bushes in our front flowerbed. We’ve since noticed that the bottom Is starting to look sickly: stems are brownish & appear to be brittle(?), and the bottom leaves are yellowing. I’ve read on your website that it could be root rot? My husband does the watering, & admits this as a possibility. So...what do we do from here?
It does sound like root rot. I'm not sure how large these shrubs are, but if they're fairly small you may want to carefully dig them up, trim away the bad roots and replant them. Otherwise, they may need to be treated with a fungicide. Here's a helpful article:

I just purchased this cute butterfly bush from a local hardware store. I potted it (my dad helped) and have been watering as it's been quite warm. The flowers have lost their color and have become browned! It gets about 6-7 hours of sun (it's on my balcony). Please help! I don't have a green thumb but I'm trying... Any ideas?
First make sure it isn't being overwatered and the pot has good drainage. Also, the flowers will fade and turn brown. You can cut them off at that point. If you don't deadhead, you will still get new spikes, it just won't look as tidy.

I saved 10 butterfly bushes from last year . They all survived the cold winter . I pruned them back in the spring . The leafy foliage is full now and growing tall but no flowers yet . Is this normal ? Is it still a bit too early In the summer ? Should I prune back the new growth or let it alone? They do get full sun . It is June 9th now and no flowers as of yet . What should I do? Thanks
Typically, the sun is all they need for good flowering. I would test the soil, though. There could be too much nitrogen in the soil. SHould the test show too much nitrogen, you can offset with potassium and sulfur.

Need some guidance on best way to deter, or rid, my butterfly bush of Japanese beetles while not deterring or harming the butterflies I am attracting. Thanks for the input
The best thing you can do is knock them into a dish of soapy water every day. They are on the wing for a short time and will not be on your plants all summer. The worst option is a device that attracts them to its container and then they meet their demise. That will bring them from miles around to your yard. Any kind of residual spray will harm the beneficials.

The leaves are speckling yellow all around and the underneath leaves starting from the bush base are shriveling you and drying out and dying, the bush is looking sparse and it was full and beautiful; this happened last year as well but much later in the growing season.
It looks like spider mite damage. Be sure to keep the bushes watered, because spider mites love hot, dry conditions. Here is info on control:
