Theoretically, if the plants are fully hardy for your zone, they can be planted at any time the soil is still workable - i.e., not frozen or overly saturated. Frost, cold temperatures or snow are not a deterrent or a handicap to cold-hardy perennials. While I acknowledge that I am in a much milder zone, it does get cold here too. I once completed the planting of an entire perennial border (100's of plants) in January only hours before the temperature plummeted into the teens and stayed there for a week. Everything made it through just fine. If the soil is not solidly frozen (typically will not happen until well into midwinter even in colder parts of the country - that doesn't include zone 6), plant now and water in well. Moist soil tends to be an insulator and freezes at lower temps than does bone dry soil. And mulch with leaves, straw, etc. to further insulate and protect against heaving. Heaving is the pushing up and exposing of roots from movement in the soil due to repeated freeze/thaw cycles. Surface rooted plants like heucheras tend to be vulnerable to this process.

You can safely plant now. As long as the plants have 6 weeks to adjust before a hard freeze, you are fine. I am a little concerned that you said you dug a 'deep hole'. Maybe you just meant that you did that to amend the soil. Daylilies shouldn't be planted deeply ---- Just a couple of inches above where the leaves meet the crown. As far as amending the soil, I wouldn't do that either. Just plant them in the soil you have and next year when they are up and growing, you can feed them with a slow release fertilizer if you feel you must. If you are mulching with something that will benefit the soil, that is probably all the feeding they will need. Order those babies and go for it!!!

when i moved here.. i brought 1500 potted hosta ... in promix.. heavy peat media ... rototilled to 12 inches .. and slipped the hosta out of the pot .. and stuck the media in the native sand ... over the years.. many cared not a bit.. and thrived.. then i started getting fairy rings [the middle dying in EXACTLY the size of the pot/media] .. and out right loss ... the problem is that the sand was wicking all the moisture out of the peat media .. especially come july and august ... when the sand was really hot ... so.. it is best.. to plant them in native soil ... and not leave that wad of media ... thought the better your soil.. the less it matters ... ===>>>>> by making the cone.. and really firming it up.. you can .. hopefully .. set and retain the plant at the PROPER PLANTING DEPTH .... if some of your hosta.. end up planted too deep ... THEY COME UP LATE ... and many will suffer ...in the long run ... if and when they come up .. and they are late.. then they need to be dug up.. and replanted AT THE APPROPRIATE DEPTH ... the pips.. eyes .. NEED TO BE AT SOIL LEVEL ... not one inch lower ... THERE are 3 parts to a hosta.. the roots.. and the leaves .. and between the two.. is a potato like thingee called the crown ... and the crown .. like an iris.. is at soil level ... another way to tell if they are too deep .. is that if the3y are supposed to be 12 inches tall .. and yours is say.. 8 inches.. and just look squat ... then you poke around.. and see if you can find the crown.. most times.. you will find it a couple inches too deep .... ====>>>> chris grows his in mother earth ... i dont know what his potting media is ... ====>>>> you do not need to remove 100% ... just shake off the majority of the media .... if it is severely root bound.. use the hose ... ===>>> potting media is not soil ... if you want to pot them .. use a PROPER MEDIA ... new post if you cant find old posts on that topic ... if no one above suggested what kind .. ===>>>> did i miss any other questions??? ken

Three beauties for sure. One of the things we sometimes forget to mention is that Chris always sends a "bonus" plant with your order. It's always a great surprise when your order arrives. But you should be prepared to have 4 Hostas in your order from Hallsons. Steve
