I recently put together some information I thought would be helpful for beginners. Maybe this will help:
Beginner Basics - Seed, Soil, Sunlight and Water
Here is some info to get you started:
"These vegetables are usually direct seeded: Beans, beets, carrots, corn, cucumbers, garlic, lettuce, micro greens, muskmelons, okra, parsnips, peas, pumpkins, radishes, rutabaga, salsify, squash, turnips, and watermelon.
These are some vegetables that are transplants: Basil, broccoli, Brussels sprouts, cabbage, Chinese cabbage, cauliflower, celery, chard, chives, collards, eggplant, endive, escarole, kale, kohlrabi, leeks, mustard, okra, onions, parsley, peppers, tomatoes and watermelon.
Then there are a handful of vegetables that aren't usually grown from seed at all. Plants started from other than seed: Artichokes by root divisions, Asparagus by 1-year old roots, Garlic/Shallots by cloves, Horseradish by root cuttings, Onions by sets, Potatoes by using seed potatoes, Rhubarb by root crowns, and Sweet Potatoes by slips."
Everyone has given you great advise.
Best wishes for your first garden.
