Garden planning

How much to plant per person

How many tomato plants does a family need? How long a row of carrots? This planning chart gives the amount to grow per person for fresh eating and for preserving, using figures from university extension services, then works out a family-of-four example and the harvest you can expect.

Vegetables and herbs: amount per person

Amounts are per person for one season. "Row" means a single row at the spacing in each crop's guide. Expected harvests use typical yields from our yield chart, so treat them as rough estimates.

How to use these numbers

  1. List what you actually eat. A big row of a crop nobody likes is wasted space, however well it yields.
  2. Decide fresh or preserve. Freezing, canning or storing roughly doubles the space for many crops.
  3. Multiply by your household. For example, for four people that's 12–20 plants of tomatoes, which should give roughly 20–34 kg (45–75 lb) over the season.
  4. Stagger quick crops. Radishes, lettuce and spinach are better sown in small batches every few weeks than all at once, so the harvest doesn't arrive in one glut.
  5. Check your timing. The harvest calendar shows when each crop comes in.

We couldn't find reliable per-person figures for basil, garlic, pumpkin, so they're left out rather than guessed.

Adjust after your first season

Planning charts are a starting point. After one season of writing down what you pick, you'll know whether four zucchini plants were two too many. Our guide on tracking your garden harvest shows simple ways to keep that record.

Garden planning FAQ

How many tomato plants do I need per person?

University of Missouri Extension suggests 3 to 5 tomato plants per person for fresh eating, and 5 to 10 if you also want to can or freeze tomatoes.

How big a garden do I need to feed a family of four?

It depends on what you grow and whether you want to preserve food. Add up the row lengths and plant counts in the table for the crops you eat most. Start with a few crops you love rather than trying to grow everything in the first year.

What is a hill in a planting guide?

A hill is a single spot where a small group of plants is grown together, rather than a straight row. Extension guides use it for sprawling crops like cucumbers, squash and melons.

How many strawberry plants do I need for a family?

NC State Extension suggests about 50 plants for four people. University of Missouri Extension suggests 25 to 50 for fresh eating, plus more if you want to freeze berries.
