I would plant it! We plant kale here in zone 5 as soon as the soil is thawed, in a few weeks you should be great for growing kale. Just be sure to harden off before planting out..... Kale is a cool weather crop, but I have had it going through the summers here in chicago. I would think you have to get it started and up and harvested before your super hot summers kick in....

Hello m taggert, The medium usually placed in those store bought Flytrap pots is long fiber sphagnum moss, which is fine. If the moss in the pot is chopped fine, it is probably sphagnum peat moss, the dead dessicated moss that layers under the long fiber dead moss which itself layers under live moss in nature. All of those products are the natural growing medium of the plant in peat bogs. Just make sure that your plants are not potted in potting soil and they will be fine until next spring. Check drainage by pouring a little water in the pot while the soil is already moist. Excess water should drain out in minutes. Those pots are small, but it will not hurt them unless the pots have no drainage. If their is no drainage, repot them or drill 1/4-1/2 inch holes in the bottoms of the pots. You can place the pots in a water tray up to 1/4 of their depth or less, never over that as that can drown the roots and induce root rot. Just slowly adapt the plants to low humidity if they are still in domes by removing the domes slowly over two weeks (lifting the dome and bracing it up a fraction of an inch every three days or punching a few holes in it every three days till it no longer holds humidity). Adapt the plants to high light levels by placing them in a morning sun window until they are out of the domes and then each week in progressively brighter all day sun windows. Once they are in a bright all day sun window for a week, place them outside if possible so they get maximum sun exposure. Leaf burn is expected until new leaves grow in with stronger UV resistance, but the plant overall will be stronger for the direct sun.

Thanks gennykins, ima digger and Mike :) You all brought up some good points. The plant does dry out quickly, but the days will be getting cooler soon and I won't have this problem for much longer, you're right. That sucker did take off this summer, and possibly it likes being potbound. All of the long vines have peduncles on them, but we'll see if any actually set flowers! I think what made me consider going to plastic was seeing all of this new growth and tiny leaves & peduncles and feeling a bit worried about forgetting to water it frequently. I lose a lot of new leaves that way. She's staying put anyway. Thanks again for the input!

Depends on how bad the health of the plant really is, but I would probably wait as well. Mine actually thrived outside all summer, though I neglected it, and like yours, is full of buds now. Christopher
