Cordyline, Alternanthera, Purple Fountain grass
Comments (5)I bring my Cordylines inside as I have ample space and enjoy the red or purple/black foliage as contrast to so many green foliage plants. I have left one outside but it came back the following spring too slowly...it was just 12" and didn't put on that much growth this summer, whereas the ones wintered inside just took off immediately. My favorite, Alternanthera dentata "Purple Knight", will grow to 36 inches here and will do well inside in pot, hold it's color, even have small fuzzy insignificant white blooms under a lamp or on windowsill. It can be pruned back easily to branch more and form smaller stockier plant. I have a couple of other Alternanthera, no label, one has bright red leaves and another butgundy foliage but only grows to 15" or so. Same care applies. I often cut tall stems along with various large Coleus and Ipomoea batata "Marguerite" or "Blackie" to make a big "bouquet" in water. Rinsing and removing dying leaves is necessary for a week or so but easy and once roots start I have a "living bouquet" until spring...just keep topped up with water. In spring I don't try and plant whole plant with roots...I just make new cuttings and discard roots formed in water. The better the light the more vibrant the colors but sun isn't necessary, just a windowsill...at least here in AL. Even a tall lamp with 150 watt bulb will do. This method also works with Cordylines, by the way...I've cut tops off and put in large floor vase stabilized with black Japanese water stones...or in ceramic pot with just plain rocks. There again, I just make top cuttings in spring to root in soil...the roots formed in water don't adjust well to soil in my experience. I find it easier to grow in water than in a large pot and easier to top up wth water with no aggravation from too much water drainage into overflowing saucer or underwatering. (I have about 100 other plants to care for...LOL). Good luck. josh...See Moregrass removal around a purple fountain beech
Comments (1)Most beeches have roots close to the surface, so this alternative should result in the least disturbance of the roots. Unless you have a VERY good reason for removing the sod, why don't you just lay down either flattened cardboard (tape and labels removed) or 4-6 sheets of black-ink newpaper and let it smother the grasses? You can spread your compost and mulch over it (no more than 4" deeep), and if you keep the edges of the paper covered (it wicks moisture from the soil, if exposed), and keep it damp, the paper will break down in a few months, the worms will mix it all together, and the only labor is spreading the paper(s), compost and mulch. If you use newspaper, and it's a windy day, spray the sheets with water as you lay them out, so you don't end up chasing them all over your yard, never mind the neighborhood! Overlap both paper and/or cardboard, so no grass can grow up through any gaps. This won't kill off really established perennial weeds but the soil will be soft enough that digging or pulling them is a lot easier - I still have to dig/pull wild onions, curly dock, horse nettle, etc., but it's a LOT easier. You may have to cut the pieces of cardboard to get the shape you need, but a sharp knife makes that easy. It will surprise you about the amount of paper or cardboard it will take, so collect more than you think you will need....See MoreWhat do you use to kill grass where you want a lily bed?

Comments (11)I've been succesful at this for 2 winters,but I do have a cool greenhouse. I use a lot of it in big container plantings. I wait until after a light frost & plant several clumps to a container. These are hernia specials LOL I pot some in smaller pots,too. ! I like to leave them out as long as I dare,so they get acclimated to their winter pots.They can take a little frost. I like to think some of the bugs get killed by the cold! Before a hard frost ,they are brought in & trimmed. Watering is tricky! Too much & the roots rot.I've done it! I like to have a small plant ,weed,petunia ,in the pot. When it starts to wilt,I water.Last year I didn't lose any & I had several.In the spring when they start to actively grow,I divide & plant into 4 1/2 or 6" pots.Even if I didn't have the geenhouse, I would still try to save them.
