so hypothetically about 4-5 weeks ago I threw some potting soil into a cut and half soda can and threw a few seeds into it and kept watering, now my plants is probably about 12-14 inches tall, healthy with a good bit of finger sized leaves, but I worry that the can in not nearly big enough so I was thinking I would transplant them to a bigger pot. The Plan.. The plan I have chosen seems to be very simple so i'd appreciate criticism/help if there's any thing that doesn't seem like it would work well. 1. cut the can off from around the soil using wire cutters(yes they can cut aluminum to) 2. take the soil already in the can and transplant directly into a larger pot already mixed with potting soil. will this work? question number 2.. alright, same time frame plants about 12-14 inch. the thing is there are multiple plants in the same 7 inch pot which we'd like the distribute into there own pots, problem is some are as close as 2-3 inches apart? all help would be appreciated.
for the can - that's exactly what you want to do. Water well. for the pot, slip the dirt out, and using a sharp knife, cut down between each plant, like you're cutting wedges out of a cake. Plant each wedge in a seperate pot of dirt, water well. Note, cutting the roots will likely lead to transplant shock, but trying to pull them apart will likely damage them more and expose most of the root mass to air. either way, plant in the new pot, with more soil, and water very well with warm/tepid water, to help minimize shocking, don't expose to high temperatures for a day or so, and the plants should be fine.
it went over beautifully for the soda can that is as for the ones close together we are doubtful they weren't really health enough to transplant but only time will tell.
yeah, that's a little sketchy, but that transplant method (for the ones in the pot) is going to be the best shot at survival for the (hypothetical) plants. It's possible that they'll perk up, but if they're not healthy enough to transplant, chances are they'd die pretty soon anyway from getting really really rootbound.
