With so much re-planting going on, as in my last post, I’ve decided to see if I can create a micro-climate cool zone, induce germination and (hopefully) the growth of a plant which grows in zone 8 or cooler. I’m in zone 9b/10.
In June, I received a present from a sweet Facebook friend in West Virginia (Zone 5b-6a) ~ yes, she sent me some fresh Pawpaw seeds! (BTW, Pawpaw in the US is Asimina triloba and not Papaya as what Pawpaw is, in Australia). Now that got me thinking … so I decided to stratify them, put them in the fridge, give them a period of cold (40o F/4o C) for 4-5 months, try to “make them comfortable” in hope of breaking their dormancy.
Florida has just experienced her first cold front this week, it means winter is forthcoming and cool weather, ideal for Pawpaw seed germination, calls for some action, right? I had already done some information gathering and know that Pawpaw seedlings will develop long tap roots so I decided I’d do some recycling instead of buying expensive tree seedling cell-pots.
My style of deep cell-pot begins with the cutting of a bottle-cap to allow water drainage but not soil/potting mix loss.
Then cutting the base off a small water bottle; screw the cap back on and fill the bottle with seeding/potting mix.
