Hello all! I am new to this forum, and have a question. I recently purchased a young Don Juan climbing rose that I want to grow up a trellis along my patio. The problem is that the spot where I wish to plant it collects standing water when we get heavy rains. I was thinking of planting the rose in an extra large container placed in the same spot, but I'm not sure how well a climbing rose would do in a container. And also, if it can grow in a container in this spot, surely there would still be a drainage issue since the container would be in the standing water? Any tips/suggestions?

If the container is standing in water, you'll have just moved the problem upwards. The pot won't drain, and the rose will be greatly handicapped.

If you HAVE to do it this way, I'd recommend some large concrete blocks stacked to raise the bottom of the pot above water level.

Two other considerations, though . . .

1. How "large" is the "large" container you're thinking of?
and
2. How many drainage holes will the pot have? (Clue: The more, the better.)

I have several roses (and other things) growing in truly large pots. For the most part, they're doing OK -- but they will probably never reach their full potential in that sort of situation. (But, of course, you do what you have to do.)Th

This pot is about 2.5 ft. tall. The rose in it is "De la Vina Mystery", which can be considerably larger than shown here, were it's feet not pinched:

Agree with Jeri. You need to get the pot up out of the standing water for it to survive. Otherwise the water will not drain properly and the roots will rot.

I've grown several climbers in pots with trellises in them. The pot does need to be very large! You don't say where you live or what zone you're in so I don't know if wintering is a consideration. In cold zones you must make plans for wintering potted roses.

Can you provide some pictures of the pot and spot you want to put it in? That may help us determine better if it will work out the way you want.

The roses I'm trying to grow in containers are not climbing roses. But I have a similar question about them. Because I'm high up on a balcony, above neighbors in other apartments, I have to have large saucers under my rose plants. I've learned to water until runoff comes from the bottom, but as the water collects in the bottom, I find that it does not evaporate. It looks gross because of all the soil amendments I have used, and it is very heavy to dump the collected water into another container of some kind.

I have lifted the parts above the waterline. Do I still have to empty the water? Will the rose drink it up eventually? Or might it evaporate? I'm in Philadelphia. It's summer now, exceedingly hot and humid.

Thank you.

@tonibowers that water may evaporate, if the humidity reduces enough for it to be able to. You do NOT want it to go back into the pots as it becomes increasingly salty from the minerals in the tap water, fertilizer and the amendments. You want the pot bottoms completely out of the water to prevent it from being drawn back into the pots. You may have to resort to a turkey baster or small wet/dry vacuum to suck the water out into another container to dump it. Hopefully you don't have mosquitoes or the water gets salty enough to keep them from breeding in it. Or, you might consider "Mosquito Dunks" https://summitchemical.com/pro... in the saucers if mosquitoes can be a problem.

Plant level pot elevator may work.

Turkey baster sounds like an easy fix for you. I use mine for other stuff since I don't need it for my minimal cooking attempts..

I use a turkey baster too for these kinds of circumstances.

Hi - I've been growing climbing roses in containers for years (at least 10 years). Mine are in big pots, but probably not what you'd call enormous. I do think some of them have put roots down through the bottoms of the pots into the gravel they are sitting on, however. I have never repotted them, though I do fertilize and water regularly. Some of them are quite huge now! They are Felix LeClerc, Cape Diamond, and Party Hardy. I would recommend roses that are hardy to at least a zone beneath you, but I see you are in 8a so Don Juan should be fine. Good luck!
