New to this in New Hampshire

My husband just built us two 6x4, 10 inch deep beds out of untreated wood. We put weed blocker cloth underneath the frames instead of building a bottom, to ensure good drainage. It would have been too costly to fill both of them with Mel's mix but we liked the idea of square foot gardening and getting the most out of small spaces. We live in a town house style apartment with very limited yard space and these two beds fit perfectly. We filled our beds with a mix of composted manure/humus, top soil, and ProMix. We also began a composting bin for next year. We are planting in two weeks and are planning on tomatoes, lettuce, onions, bell peppers, kale, radishes...I'd also like to try celery using the celery bases we have and rooting them. Anyone have any other suggestions about what we should plant and what goes good with each other?

I had no idea what they were until I started on this forum. Crops like Broccoli, lettuce, spinach, kale, chard, onion snap peas, and radishes can all be planted NOW!! The tomatoes and peppers have to wait a bit, but get those others in the ground and start growin'

Hi and to the forum. I am excited that you have decided to start SF Gardening. I know that the Mel's mix seems costly but one of the reasons SFG work is because of it. How full did you fill your 10" boxes? You only need 6" of MM so I might recommend gradually amending the top 6" of your boxes to MM as you can. Square foot gardening takes a lot of nutrients and I just want your garden to produce to it's fullest potential! Below is a like that I like for companion planting!

Welcome eliejg from a Maine neighbor. I'm in zone 5a and right now I've been transplanting cabbages, broccoli, cauliflower, Brussels sprouts, Pak choi and sowing seeds for turnip, lettuce, radishes, radicchio and greens like arugula and mizuna. Also carrots and onion sets, spinach, peas and Swiss chard are in. My herbs are in pots for the season: rosemary, tarragon, parsley, thyme, basil. I'm sure you can do the same.

Next week I'm putting in a few tomatoes and peppers to get a jump start on the season but saving most of them til the end of May to be sure of no more frosty nights. I keep old sheets and towels handy in case we get a frost overnight. Some things, like many brassicas which are cabb, brocc, brussels like a frosty night now and then.

Eggplant, if you plan any, doesn't like night temps below 60 so wait on those til it really warms up unless you pot them and can bring them inside when temps drop into the 50s.

Yesterday I sowed seeds for Nickel Filet bush beans and Little Marvel bush peas along with cutting celery (a green that tastes like celery).

This week I've sown seeds for zukes, pie pumpkin, watermelon, cantaloupe and summer squash but put milk jugs over them to help germinate quicker and keep warmer. If I lose them, I can start again. I don't bother starting them indoors. They'll catch up if just sown outdoors when its warm out so I don't waste my time or soil or pots starting them indoors.

We're always here to answer questions. Growing an SFG is the best way to grow.
