unless you want to eat them all the time or terrorize your neighbors with
free zucchini 3 or 4 plants is all you will need to have an ample supply for a big family, dont waste space growing them, once they start fruiting they will give you an abundance. Cucumbers like to grow more or less by themselves and dont like to be top watered, i grow cukes for pickles so I like to plant them all at the same time to get my canning done all at once. carrots and beets can stay in the ground if you dont have time to deal with them, so I plant them all at once as well. same with onions and potatoes. i do like to plant my greens about every 1-2 weeks to have a steady supply of young tenders. same with sweet peas and green beans, although if you are diligent about harvesting the legumes will keep producing, especially in your climate. most other crops are long season, here in Mt we only get one harvest, but you might do well growing spring peas, carrots, radish and green onion in the spring, harvesting and then moving to 3 sisters (corn beans winter squash) in mid summer for fall harvest. Brassicas (broccolli, cabbage kale etc.) are heavy nitro feeders, so dont follow those in your corn or potato beds. Typically, follow a legume crop with a root or corn crop and "fallow" with carrots and greens and radish. I like to sprinkle all my beds with alliums as they tend to ward
pests and cohabitate with most crops. Peppers and
tomatoes, eggplant and basil all love eachother, and I usually plant those together, and follow next season with legumes to amend the soil. If you plan on tilling and cultivating every season, make sure to rotate your crops, potatoes and turnips for example will develop scab and root worm if planted in the same patch again and again. strawberries like shallots and garlic. Plant sweet peas everywhere. let them grow as weeds and pull them out as necessary to plant other crops. Clover is a good cover crop, so dont pull it out when weeding, unless it gets to aggressive for your seedlings, a good "chop and drop" weed. Radish and bok-choy are good to plant on marginal soil or over-looked corners of your garden that you cant find the time to get to. they grow fast and will loosen the soil when you harvest to prepare for seedlings or direct seedlings. Learn to love dandelion, mullein and comfrey, they are
medicinal and do a great job adding nutrients and minerals to your top soil. ( a weed is a plant whose value is overlooked)
hope this helps...
