Starting a Vegetable Garden: The First Five Decisions

By GardenPlanner Team · July 17, 2026

Most first-time vegetable gardens fail for boring reasons: too much shade, too little water, or a bed sized for enthusiasm rather than time. Get these five decisions right and you’ve already avoided the most common mistakes.

1. Find your zone

Everything else in this article — what to plant, and when — depends on your USDA hardiness zone. It’s a shorthand for your average frost dates, and it’s the first thing to nail down. Use our planting calendar to look yours up by ZIP code.

2. Pick a sunny spot

Most vegetables need 6+ hours of direct sun. Watch your yard for a day before committing to a location — shade moves more than people expect, especially as trees leaf out in spring.

3. Start smaller than you think

A 4×4 raised bed (16 square feet) grows more food than most beginners expect, and it’s small enough to actually keep weeded. Our Garden Designer uses this square-foot-gardening model — you can lay out a bed, place plants, and see exactly how much fits before you build anything.

4. Choose a few plants you’ll actually eat

Skip the seed-catalog impulse buys the first year. Five or six vegetables your household already eats — tomatoes, lettuce, beans, herbs — will teach you more than fifteen unfamiliar ones. See our companion planting guides for what grows well together.

5. Know your soil before you plant

Bagged garden soil varies wildly in quality. The Square Foot Gardening blend (compost, peat moss or coir, and coarse vermiculite, in equal thirds) is a well-tested starting point that drains well and needs little extra fertilizer in year one.

Once those five are settled, the planting calendar will tell you exactly when to start seeds indoors and when to put plants in the ground for your zone.
