You sure you want to follow me along here?
It turns out that when you're thinking about fall crops, you need to think about the winter cover crops/winter crops (what to plant, where to plant).
... and if you want to think about winter cover crops/winter crops, you need to think about what you'll be planting in that bed next spring and summer.
For example: I have a pre-designated sequence to follow for the rice paddy (as per OSR
, M. Fukuoka)
Summer: Grow Rice
Early Fall: Sow Clover + Rye or Barley (I'll be using Rye)
Fall: Harvest Rice / Grow Clover + Winter Rye
Late Fall/Early Winter: Sow Rice
Early Spring: supplement Clover if necessary
Late Spring: Supplement Rice if necessary / harvest Winter crop
I'm trying to rotate out the curcurbits, and only bed I have that isn't growing any this year is the New Kitchen Garden. I'll want plenty of N and plenty of mulch, so I'm thinking Hairy Vetch and winter killing Oat for Winter Covercrop. I'll want to sow parsley to overwinter too. In spring, I'll want to only sparsely plant things that will come out by late June/early July so they'll be out of there by the time the pumpkins and squash neeed the room. Pumpkin and Butternut Squash seems to be a common combination.
I've started thinking about all my garden beds in these terms....
p.s. that seminar sounds interesting. Please let us know what you find out.
