I've started rooted cuttings from Black Krims, Momotoro, and Sioux vines that gave me a bumper crop this past spring. I had the healthiest plants EVER, and the most bountiful harvest EVER of all my growing seasons combined. I have what I believe is a Sioux plant that is filled with lush new top growth, so that'll be the start of my fall crop. I'll only grow those three varieties.
The substantial size shoots have been rooting in a bucket of water with a capful of H2O2 for oxygenation, since Saturday, and, the roots are huge already. I have to get them into some soil before the stems start rotting. Problem was figuring out what to plant those long suckers in, without using too much potting mix. Plastic two-liter COKE bottles to the rescue!
I cut the top off even around with the top of the label, filled with Tapla's 3-1-1 container mix, and sunk a dowel down to make a hole. Then, I threaded the stem carefully through the pourspout of the cut off top and into the hole, pressed in the soil and lowered and taped the top back into place. The plant doesn't tip over because of the leverage from the hole. Then, I watered them in and placed them under the patio cover to continue taking root, until plantout between 8/15 and 9/15 (my absolute cutoff date).
Once the bottles fill up with roots, I can just cut the plastic bottle away and lift the whole rootball in one piece for planting out.
I need more Coke bottles...
