I am near Washington DC. Some of my roses will be here mid-sept. Was thinking of moving them at that time. Let’s see..
Thank you for responding.

If you want to do it when the new ones come just wait until the temps cool down. I've done it in August but you really have to stay on them to keep them watered when it's this hot.

Dig your new holes first and do a drainage test if you need to. That will also water the hole well for the new plant. Then dig as big a root ball as you can get and transfer it to the new hole. I use a wheel barrow or tarp to move the plants so I disturb the root ball as little as possible. Replant and WATER! I would not fertilize at all for this year. Just keep them hydrated. They should be fine.

OP can you request an October shipping date for the new roses? The DC area has recently been blessed with rain (with possibly more on the way from a hurricane) so the soil moisture is good but September can be awfully hot here.

You can transplant now but be sure to water water water so to avoid transplant shock. Since the soil is still warm they should settle in before the first frost arrives in November.

I'm about a hundred miles south of you, in Gloucester, VA. It's zone 7B here, but I used to live and garden in the DC area, and I don't think there's much difference.

Yes, it's fine to move things and plant things in the fall. September is excellent. The limiting factor is lingering summer heat, not oncoming autumn cold (as if!). I'm going to be moving roses and planting new ones starting this weekend, and I'll just take care to keep them well hydrated. We can still have 90-100 degree days ahead.

Make sure you give your roses good deep drinks when you move them, and keep an eye on them especially on hot days. I always give a solution of root starter fertilizer (Miracle Gro Quick Start) when I plant. If you use systemic granules, you can also put those in the hole.

btw, with climate change many of my roses are no longer going dormant in winter at all. They don't grow, but they do keep their green leaves. Very last blooms are usually in November.

Hi there! I'm in 7b in NC and I like to wait until more like October here. I want it to cool down quite a bit and start raining a lot again. When I move roses I cut them back about halfway to balance the root loss. If it's a new spot it's horrible clay, so I dig a 2'x2' hole and fill it back in with half-and-half original soil and compost. Then I water it well, let it settle for a day, and top off before planting.

In my mind the time you plant daffodils is the time to transplant roses. ^_^
