Three simple questions for those who have daylilies in containers:

(1) What do use as potting mix?

(2) Do you change (replace) the mix from time to time, and if so, how often?

(3) If you never replace your potting mix, then you must have some way to revitalize the mix form the top - how do you do that?

And I'm throwing another question into the mix.

Can daylilies be left in pots over winter in zone 5 (for those who might know)?

I have grown them over the summer and then planted them out into the garden in the fall- but I don't know if I'll get my latest flowerbed filled in time to plant in it this year. Might have to figure out a temporary winter spot for the five I have in pots this summer and replant them in the ground next spring.

Plain potting soil, whatever is on sale. I never use moisture control. I grow in very large containers. I fill the bottom half of the containers with pinecones, needles, chunks of pinecone bark or chips. Someone mentioned putting newspaper around the inside of the pot, that is a good idea I want to try. After the daylily is in, I make a well or a ditch all around the pot. Fill it with alfalfa pellets, cover with soil, sprinkle with 10-10-10 fertilizer and milorganite to keep squirrels out. I repeat this in spring and fall. In the spring, extra potting soil might be added on top. In the fall, I put a tarp or cardboard next to the pot and tip it, pull out the daylily, set it on the tarp. Take some soil out from the bottom, small bucket full. I add more pinecones, etc. to the bottom. Put a little fresh soil in if needed. Put the plant back. Make the well and repeat above. I use the bucket of soil to cover the pellets. My soil has lasted 3 years.

When I had unlimited rabbit poo, I never had to change the soil just mixed it in on the top. But at least every other year had to put new pinecones and such in the bottom.

I lose between 3 or 4 inches of soil every year. Probably the breakdown of organic matter, very little soil washing out. Just enough to have to add more soil which seems to keep it all fresh.

I recommend never setting your containers directly on the ground. I used patio stones, porcelain tile, and wood scraps (but they deteriorate). The patio squares and tile do not have to be new. Curbside or craigslist. This helps keep the pots level and tree roots out. If your containers are not level there is the possiblity of rot. Half the pot is too dry and the other half stays too wet.
Tree roots up in the container means all new soil. A do over which is no fun.

Sorry, Diana... being in Texas I do not know anything about daylilies and cold safety. And after all these 106° and 108° days maybe I should pay more attention to colder areas.

Hopefully this helps...and may the remainder of your week be exceptionally wonderful!

Sharon, thanks for the very thorough write-up.

Diana, first find a corner that is protected from the wind, then buy some inexpensive landscape fencing and build a barricade around them, then cover them thoroughly with mulch.

I have dozens of daylilies in buckets. Yes, they can be overwintered, but you need to take appropriate measures. I make a bed of leaf mulch (tons of fall leaves to be gathered for free around here), place the buckets on their sides on top of it, and cover with a LOT more leaf mulch.
I've learned that one of the secrets is to turn the containers on their sides early enough that they don't overwinter with freezing rain/snow inside of them. I've lost a few to crown rot that way.

I have carried potted daylilies over winter here in my zone 4 garden. Against a south facing wall sitting on the ground, regular potting soil, buried with cedar mulch to the top of the pot and about two inches of the cedar on top.

Worked fine here.

I second the "don't put the pots on bare dirt". I've had shrub and tree roots invade - not good.

Since we are generally arid here, I put the pots in/on plastic saucers. If we are having heavy rains (a possibility from late fall into spring), then I might take them out of the saucers (otherwise there is a risk of rot). I generally don't water enough for rot to be a problem in the warmer weather, though; whatever water drips through to the saucer is pretty shortly taken back up by the pot/plant again, or else it evaporates.

Apart from protecting the pots from tree root invasion, this use of saucers allows conservation of water which is pretty important; potted daylilies that I have had sitting out on stone or wood without saucers generally don't do as well as the ones on saucers, even though they get watered as much. Having that reserve of dripped water in the saucer really does seem to make a difference.

(Sorry, zone 9 here so no help for cold weather.)

I pretty much do what Sharon Rose does. I also live in Texas, Burleson. I grow mine in large pots most of them being 11 gallons or around that size. I recently made a new daylily bed with black plastic under and gravel on top. Also because I'm old now, I put in sprinklers on the corners of the bed. It was 111 degrees here yesterday ugghh. Here is a picture of my new beds with sprinklers on the corners, it is 20 foot by 20 foot. I get some shade early morning.

@daverme when there's no time to plant your daylilies in their permanent location before first frost, you can "heel (sp?) in" your bare root daylilies. I read about this technique, somewhere, a few years ago, and I can't seem to find a link on the web for you Glare but it has worked very well for me a couple times, and I am located one zone colder than you.

So to heel in your bare root daylilies, determine a good temporary location in a garden for overwintering. I use my veggie garden. Smiling What you do is, cut the foliage back to about 4 to 6 inches long. Then dig one shallow hole per daylily at an angle, with the deep end at about 4 or 5 inches (or more if you like), and you can space them side by side, a few inches apart. Then lay each daylily in, with the foliage sticking out of the high end, being sure the crown is a couple inches down from there, in order to be covered with soil. Lay the roots straight in to the deep end. Then simply fill in with soil, making sure there are no air pockets between the roots. Water them in, and then cover them entirely with at least a 3 inch layer of shredded leaves, compost or straw. The thicker the better. You'll see new growth as Spring approaches and the temps get warmer and warmer, and when the thaw comes, dig them out and plant them in their permanent locations.

Hope this helps! Smiling
