First, bush isn't the best name for them - compact would be better. 'Bush' zucchinis have short distances between nodes (leaves). They're still vines, just shorter vines. I typically grow Black Beauty, and the vines generally don't go much longer than 24 inches. Last year I planted three in two hills within a four foot wide bed, and they barely peeked over the edges by the end of the season. That's pretty darn compact, considering all the fruit I got off them.

You made a mistake by cutting them back last fall. In your zone you should not prune your roses in the fall. Wait until spring. The roses store nutrients in the canes and you cut that supply off when you pruned them. That being said, last year was a particularly bad winter and you probably would have lost most of the cane anyway. Nothing you can do about that. We all started out with shorter than normal roses this spring. They'll need time to recuperate and rebuild their structures. Knowing what roses you have will also help us to determine how large and bushy you can expect them to get. Roses can take from 3 to 5 years to fully mature so be patient. As for the puckered leaves we really would need to see a photo of them to be able to diagnose what's going on. Why are you using the Bioneem oil? Do you have a bug infestation? If not then you don't need it. If you do not have a specific insect that you have correctly identified and are using the correct product for that bug, you could be killing off beneficial insects instead. That could set you up for an even worse problem later on. Only use insecticide when you have a bug, know exactly what bug it is and determine the correct insecticide to use for that bug. Not all insecticides work on all bugs. For now I would keep them well watered and fertilize them following the instructions on the fertilizer carefully and be patient.

What you are suggesting I have tried on other single stem plants, but was not successful. If it were possible to split the stem, or trunk down through the roots so each half would have some of the crown AND some roots you might do it, but I don't think it is possible with the plants you have. I also do not think any dressing or sealing material would help. Al

i have been on enough garden tours ... all the way up to national tours ... and frankly ... what pops out in many gardens.. is the weirdos .. lol ... aka: the weirder the better ... and one of the base reasons someone ended up with something so unique ... is some animals started the whole process ... one of the premier tree growers i know.. simply stated .... ALL TREES RELEADER .. the only issue is.. it happens in ... wait for it.. tree time ... and since this is in your best spot... perhaps you wont be able to wait for this to happen .... you might be able to pull up one of the side branches ... but frankly ... as many times as i tried that ... i failed... and.. in tree time.. the tree did it itself ... if you are so inclined .... do it in the most bendable season .. and that might not be fall .... imo ... move it out back ... and enjoy watching how it responds ... and replant something else in your premier spot ... ken
