That question I have ask so many times not on forum but at nurseries.

I am not sure where you are at ? But here in FL , we don't have any time limit. We can plant any month Bec it is so tropical. When I ask that question usually i get a sarcasm as "Are you a northerner than don't worry". Plant it anytime....lol

I don't like dealing with heat and humidity here in June or July but I do it in the evenings. So, I am still planting roses here and in July and maybe in August and who knows :)

I wonder what others have to say :)

Same here, but I’m in FL too. I usually try to track the weather, and plant right before a rainstorm. Tropical depressions are great, because they usually mean several days of cloud coverage, so I prep my planting areas when hot & sunny, usually at sunrise or sunset because of the heat, and then plant like crazy when it’s cloudy. I won’t put anything in the ground if it’s 95 or hotter, but have been amazed at how resilient plants can be if heavily mulched & watered at planting during the summer. I don’t put anything perennial in the ground after Nov. and then not until Jan., if bare root, and at the end of Feb. if not dormant. I’d love to know what classes of roses are more flexible with planting—great question!

That question really doesn't have a rock solid answer. It depends on where you are and what kind of weather you are having. I'm in zone 6 too and generally we stop planting by the end of June. After that it is usually too hot and dry for the plants to do well. However, if the weather stays cool and you can give the new plant adequate water you can plant into July and even August. Some people even plant in the fall for next spring but I don't do that anymore. I never had any luck with fall planting and lost all the ones I tried to winter kill. Of course there are many different zone 6 regions and they all may have different time tables. Knowing where you are located would be helpful.

Here I stop planting 12 weeks before a hard frost would hit... So around beginning of July...

I'm in northern MO, so we definitely have a winter to contend with but nothing like Jim's September frosts! Seil, we've got those hot, dry summers too - usually. This year has been so mixed up I don't know what to expect. Perma, that's a good plan - less watering and effort-free shade, just more time in the heat beforehand. Plumeria, humidity is awful - what we get is bad enough, I don't know how you guys in the South deal with it.

Lisa, have you noticed any classes that do better going into the ground at the start your growing season/winter vs. dormancy period/summer? Sounds like enough water and providing shade are key to getting anything through those summer plantings. I'm almost afraid to ask, but how much water is 'a lot'?

I was trying to decide if I should order a replacement for the Brother Cadfael I asked about in another thread, and got curious about just how late is too late to plant roses in different parts of the country/world.

I figure if someone sends it to me in Southern Oregon, then I'm planting it

I planted Darcy Bussel in Sept and she bloomed in to Dec. What a babe

Really. I don't normally plant after Sept. but that is mostly because by then I am too pooped to do any more

Anything I've planted after about mid-June doesn't have enough root system to survive my winters and I've tried summer or fall planting of roses many times. Others have found this to be successful, but I can't even overwinter potted roses that I plant later than about now. I don't think it has anything to do with the classes of the roses, though it's possible I could overwinter a summer planted Canadian rose because it's so hardy (though I've lost at least 2 John Davis roses planted late in the year).

Bottom line AC is that in our zone I wouldn't plant your Brother Cadfael till next spring. I haven't found that rose to be among the hardier of the Austins anyway and he needs all the help he can get.

It depends on how big/mature the rose is. A liner is risky for you to plant other than in early spring, about early May. A gallon can go in until August 1, at the very latest. Bare root, spring only. Fall planted bare root....no good in cold zones.

As a precaution, even the hardiest rose would greatly benefit from a heavy winterzation of medium pine bark mulch, mounded generously at around Thanksgiving time, on any rose planted that (this), year, regardless of size or being bare root. Winters thereafter, winter protection is dependant on the variety.

We usually plant in the Fall, because then the rose (or any other plant, for that matter) will be watered all Winter by rain. However, here you can plant anytime, you just have to make sure the new plant(s) get plenty of water all Summer if you plant in the Spring or Summer. They need more water than usual to get established, and in the Winter Mother Nature does that, while at other times we have to do it, because our NORMAl weather includes NO RAIN from May to Nov.

I am still planting in zone 6a and 5b locations, have about 45 potted roses to plant from the spring order, they were potted bare root in April. We get a lot of rain from The Great Lakes, that helps the newly planted roses a lot.

AC, I just made sure the soil was moist at all times, without being soggy. I do have heavy clay soil, so it really retains water well. At first I was watering it daily. I just had my boys plant two ‘Bolero’ bands into the ground several weeks ago. I’ve been watering them about every 2-3 days, but it hasn’t been very hot yet this year. Lisa

I guess I've been lucky, but I plant own root bands all season along. I usually have more to plant than is humanly possible, so I'm planting right up until it starts cooling off in fall. I put a bunch of bands in the ground last fall, and for the first time ever, I mounded shredded leaves around them. I've never winter protected before. All survived, but wow, what a lot of trouble. I don't plan to ever do that again. I didn't get all the wet leaves pulled away from the canes until just a couple weeks ago because we've had rain or wind, or both together, constantly - not our norm. No canker, thank goodness. I was worried about that.

Here in Italy,with the hot,dry summers,planting season is fall and winter. I once tried planting out potted roses in the spring,and most of them died ; one did survive but I had to put it back in the pot and it took a couple years to bounce back enough to go out again. Basically Melissa's rule of getting things all planted out by Christmas hold true, though I have done stuff in January.Just goes to show that its different for every climate and conditions.

I tend to stop planting during the months of June, July and August just because it’s so darn hot and I would have to water everyday to keep the poor things alive in my heat. I plan on moving some roses this fall when it cools off but wouldn’t dare try now.

If a rose is a potted rose, not bare root, I think in ground planting would be better now than the patio if you can water in the heat of summer.

I don't have much of a choice with the roses I already have - due to the weather, delays getting dirtwork done, and illness, I have a bunch still in their nursery pots, waiting to go into the ground. But today I got 13 out of the pot ghetto and into the ground, and The Wedgewood Rose is in it's (hopefully) final spot. I'm hopeful I'll get almost everything else in the ground in the next couple days. We've got rain in the forecast most of this week, but I'll water on days we don't get any and keep watch - if they start drooping I'll rig a shade cover.

Based on what you guys have said, I don't think I'll try to get Brother Cadfael replaced this year - it would be at least another week before the plant would be here. Everything I have right now is in pots, nothing smaller than 1 gal. Hopefully winter doesn't stick around until mid April next year, and we actually get spring instead of going straight into summer temps.

My phone doesn't take the best pictures, but here's one - 'Winter Sun', 'Princess Elise', and 'Julia Child' in front of the tower, in that order. 'Lady of Shalott' has been planted for a couple of weeks, and I'm hoping she'll eventually climb.

Now I just have to put down cardboard and mulch on top. And keep on top of the watering. I'll be completely finished one day, I swear - hopefully before fall gets here!

I plant own-root roses, mostly one and two gallons from RU and ARE so the plants are good size. Here in SE Virginia, which is the northern edge of 8A, we can plant in April but sometimes need to protect the roses in the garage against late frosts.

Last year I ordered a bunch of teas, which love our heat. I decided on fall planting. AWK! We had a freaky winter and they were killed almost the ground. I've been here over ten years and have never had that happen.

So, here with my own-roots, no more fall planting for me! I could have easily lost one of those young plants and all 6 were terribly set back. They are not even knee high yet.

Good information here. Fall planting is something I've always wondered about - how far before the first frost, and do roses have a definite preference, like fruit trees (which greatly prefer a spring planting). I never knew....

May try a Quadra this fall, if I can finally afford it, since AFAIK, there's only one source for it (Hortico). Plus it's supposed to be so hardy you could plant it January and it would be fine. (Any comments on experience with Quadra welcome, BTW.)

I'm in zone 7A, mid-Virginia.

High Country Roses has Quadra too, although not always in stock.

What Barbarag write just goes to show that you can't always rely on "zone" stuff-at all! Here is about a zone 8b, yet fall and even winter planting is essentail for me! That said,I did almost lose an established own-root Archiduc Joseph,due to an overly-exposed planting spot and a freak late cold spell. Dug it up,potted it,now is doing fine,but won't be putting another tea up there,for sure!

In zone 9b, Northern CA, very hot, very dry, I now plant roses any time of year. The only time of year here that is tentative is during the 100 degree summer months. But after one year not being able to resist a purchase in the middle of the summer, I learned that with plenty of water and some initial partial shade protection, they did just fine. I think dealing with the hot end of the temp spectrum is workable for new roses. Sounds pretty clear from others, that dealing with freezing temps is another story.

Today drops in to the 80s. Lady of Shallot gets her new dirt home.. Maybe Bolero too. Finally!

At least one side of the front yard will be done.

You can always sink the pots into the ground that way the roses won't stress from heat, keep them well watered since, even in the ground they tend to dry out quicker, and even leave them to winter over. I haven't lost a single rose this way except to voles those nasty buggers.

I have 3, 1 gallon HT roses coming on Monday which will be going in the ground. I figure since they're more or less 'established' plants and if I keep them well watered they should be okay. Plenty of time left in the season.

Sharon, won't that stop the roses from growing larger?

Or am I missing something?

jc, I think she means temporarily, as in until she can get them planted into the ground. I have done the same thing. It’s kind of a compromise between keeping them potted on the patio, (where they dry out quickly and need water twice per day in summer) and planting them in the ground. It keeps the roots cooler(summer) without actually planting the rose. In my case, I use this trick when my sons have dug the hole for me, but I’m not physically up to planting the rose yet. I just pop the container into the hole, mulch the top, and water as needed. It works great! I just need to remember that the rose isn’t actually planted in the ground yet. I once had a rose grow it’s roots right through the drainage holes and continue growing on its merry way! Oops! I ended up just leaving it. Roses grow enormous here, and it helped keep it “mannerly”, for a while:). Lisa

Thanks, Lisa!

I have 4 bands that I might try this with.

I don't want to plant them in the heat of the summer where they don't get much shade, but I'm also worried about them drying out and/or burning in their pots.

Lisa, I did that, too - left a band in the ground, but forgot about it. You probably didn't forget, but my brain is older than yours. Northland recommends that you 'plant' the entire pot, water, then gently remove it, leaving the hole, push the plant out of the pot, and drop it into the perfect hole; then just water it in. I did the first part, then forgot about it. It was there for years. The bottom of those band pots are almost completely open, so it was happy.

What Lisa said. If the pot is large enough the rose won't outgrow it in one season. I have a Vanilla Strawberry hydrangea that has been in the ground in the original pot for about 4 years. It is as big as the planted one and flowers as well as the planted one.

sharon

I have done potted roses in the ground before, I cut the bottom of the pot off, so the root could grow.
