I live in a suburb of Minneapolis, and I had a wonderful harvest from my backyard vegetable garden last year. I had corn, tomatoes , cucumbers, carrots, radishes, green peppers, broccoli, bush green beans, bush yellow wax beans, zucchini, peas, and even okra.
I've already made my garden area larger for next year = 1,800 sq. ft.
Next year:
-- Grow lots more corn.
-- Grow a lot more onion sets.
-- Grow more cucumbers.
-- Grow more green peppers.
-- Grow more broccoli.
-- Grow more carrots.
-- Grow pole beans rather than bush beans.
-- Grow the cucumbers on vining structures just like the pole beans.
-- Try my hand at growing potatoes.
-- Add swiss chard, bok choi, pumpkins, and cantaloupe.
-- Had 26 tomato plants last year; so, I'll keep that number.
I learned a TIP from one of the gardening books I got at the library for planting carrots and dealing with those teeny tiny seeds. Either on long strips of toilet paper or newspaper, and using tweezers, place a carrot seed at the correct spacing. Make a weak paste of flour and water and put a little dab of it on each seed. When dry, this can be done ahead of time by rolling up the toilet paper or newspaper strips, put in a bag, and put in the refrigerator until time to use. Plant at the correct depth; and, the carrots will grow in nice straight rows.
I already have a fenced-in yard, but I also fence around the entire garden area to keep the three dogs out.
I have a compost bin which I use for enriching my garden soil.
And, last summer, I bought two 37=gal. garbage cans which I put behind my backyard shed and directed the gutter downspounts into them to collect rainwater for the garden.
During the winter, I save all egg shells; wash them out; and put in a freezer bag. Tomatos and green peppers love the calcium. Come garden time, I nearly pulverize them and add it in the holes where these vegetables are planted.
I also save the cardboard from toilet paper and paper towels to put around tomato plants when I plant them to ward off cutworms.
I also grow 3 types of leaf lettuce, but I grow this in those long, rectangular, plastic planters on the ledge of the deck. I have grown my lettuce like this for many years and have had tremendous luck.
