New, need advice about winter protection
Comments (6)Judy your need to protect southern genetics from cold depends on several factors. Each one has varying degrees of ability to withstand cold.. obvious to say.. but applied it does vary. If the plants are growing well and one gets a real harsh cold event earlier in the fall.. say a rare tank down to 17F or some unreal number that can and does happen here... some tender daylilies can DIE from these events. Should these come around.. do cover well for that event. Most all southern daylilies will cold acclimate to some extent as fall temps gradually get colder. Once the ground starts to freeze.. the main idea is getting the ground well frozen sans killing the plant. Then avoiding sunlight and warm days from thawing the crown soil area and restarting growth in the vigorous Ev types. Cover that plant with a 15 gallon garbage sack full of leaves.. use a white color.. this reflects more sunight and doesn't heat as much as darker colors. Do try to use DRY leaves.. wet ones heat on those sunny days. As fall into winter progresses.. before real cold air comes staying under 20-25F.. do cover those tenders with said bags in a block fashion... a good 3x3' area and more around that crown. Best to have them all in a group.. bagging the whole area. One can use an indoor/outdoor thermometer.. placing the outdoor probe near the crown level of the plant you figure is the most tender. I don't like to see temps under 17-20F... mine usually hover around 20F on the southside of the house for the coldest. Daytime temps are higher. Once everything is froze in well... pile all the snow you can on that area. The most tender plants also can be parked in the beer fridge.. pot'm and set them up at 35-40F. Make sure they don't go dry.. but this is the safest way to protect your more whimpy plants....See Morerooted baby hydragnea's, zone 5
Comments (5)radovan, I'm describing a technique using semi-hardwood or hardwood cuttings. If these are what you've used to make your starters, you can place them in cold frames, but bury the pots in soil, and cover with mulching. They will go into a form of dormancy and will need only protection from the freeze and thaws cycles of winter. This is why the cold frame is helpful. It keeps the conditions inside the frame constant. Normally these semi-greenwood and hardwood cuttings are made in the summer and by fall, these have rooted enough that they can be planted in the ground. I've been successful using these technique with annabelles and limelight pgs. For softwood cuttings - I would follow vicky's suggestions and place these cuttings in an unheated garage.

Comments (22)Natchez Glen...I've had the Ryusen for a number of years...until we had the nasty arctic air move in for long periods. Never an issue with walnut seedlings. Glad to hear it's not the actual juglone that is an issue. Never in 24 years of living here...have we had any seedlings appear from our tree. Guess we have hungry critters out in our rural area to leave them root. Trust me...I enjoy working in the yard...and my bonsai hobby. But, I believe it pays to know what one is getting into. Since it's a large investment for trees especially. But, also since I have years back lost much landscape material not understanding juglone was an issue or that it even existed. The nursery staff is what wigged me out saying that it would be difficult with my wanting to plant in the open. Thus...my asking questions here. I wanted to stack the deck in my favor with my next selection....See Morewinter protection advice for rose cuttings/transplants
Comments (2)I would plant them. The ground is the best root protection there is. If you get them in now they should still have some time to settle in before winter hits....See Morewesterly pacific
