Upstate NY here - I’ve got 5 raised beds, each 6 x 12 and a few other smaller raised planters.
Some things I do:
1) Trench amd fence
2) Run gutter guard mesh across the bottom of the fence
3) Till organic cow manure into the soil. fortunately we have friends that run an organic diary farm with about 150 head so we get as much as we want. But things like Moo-Doo will work as well.
4) We grow -broc, Cali, Cukes, beams, lettuce, squash, tomatoes, eggplant, peppers, kale.
5) We rotate crop each year - one bed is always dedicated to tomatoes and we are giving them away we have so many. For our peppers we drop in 4-5 matches in each hole before planting,
6) Use landscape fabric over the top of the bed and run soaker hoses on a timer under the fabric
I like my plants started, just because it’s eaiser.
