what size pots for mirabilis

I just got 10 roots from Brent and Beckys. I know that I don't want to put them in the ground after reading everyones horror stories. Question is, how big of a pot will these carrots need? Keep in mind I want to keep them ALL on my front porch together.

Each plant could grow about 4' high and across if they have enough room. If they don't have enough room, they will inter-twine.

The root zone (if that is what you mean) should have at least 2" of soil below the bottom of the root, and the pot should be at least 8" across. You could put several in a whiskey-barrel type container, that would make it easier to keep them watered, while giving them plenty of room to spread their roots.

You should have a really gorgeous porch in a couple months! And very fragrant when evening comes and the blooms open.

Thanks so much Lupinelover. Do you mean 2" below the now 4" long root, or 2" below it once it gets ? long? I just don't know how long they get.

2" below what the root lengths currently are :)

Ah, thanks! :)

Hey Lupy...if I pinch back my 4:00's, that'll help them bush out a bit, right? But in the process, will it cause them to flower much much later?? (Some of mine are beginning to get "leggy" and I want them to be able to have the strength to support the flowers.)

try giving the newly trimmed or pruned four o's a shot of Epsom salts..watch them grow and bloom! E.

'Shoe, I have never noticed that pinching mine back either controlls their legginess or delays flowering.

Course, I grow these in almost full shade (ducking) and in soil that has never known any fertilizer or supplemental irrigation. Can't seem to do anything that makes them better or worse. Just gorgeous :)

No, I don't deliberately mistreat my plants!!!!! Just love to experiment and play ... and I only have a very small area of 'full sun'. Hostas and ferns are wonderful, but I don't want to only have these!!!!

Roseelaine, it makes sense to give them epsom salts; after all, they are semi-woody, and that really does a great job on all the woody shrubs that I have treated. Tons of basal breaks.

Yeehaw! So in other words, these are in the realm of my favorites..."low maintenance".

Ours in the ground do just fine leaving them alone, so I do. I have gazillions in pots tho right now that I'm bringing up in size to sell at the mkt (thanks to the idea ,and seeds, of ZZTopsoil!).

Much obliged for the input. By the way, Roselaine, I'm a big believer in Epson's!
