How Much Do You Actually Get From One Plant?

The short answer

A healthy plant in a good season gives a fairly predictable amount. A slicing tomato gives about 12 lb. A summer squash gives about 8 lb. A potato gives about 3 lb. A bush bean gives about 0.75 lb, which is why nobody plants just one.

But the number by itself is only half the answer. Yield per plant splits into two kinds. Some crops hand you everything in one day. Others hand you a little at a time for two months. A 3 lb potato plant and a 3 lb hot pepper plant are not the same experience in your kitchen, and planning them the same way is how people end up with too much zucchini and not enough potatoes.

Yield per plant, highest first

These are the per-plant numbers the planner uses, along with the spacing in the row, days to maturity, and whether you pick once or all season. Read the harvest column as carefully as the pounds column.

• Tomato, slicing: 12 lb per plant. 24 in apart, 110 days, picked continuously.
• Winter squash: 12 lb per plant. 36 in apart, 95 days, single harvest.
• Tomato, paste: 10 lb per plant. 24 in apart, 110 days, picked continuously.
• Tomato, cherry: 8 lb per plant. 24 in apart, 95 days, picked continuously.
• Summer squash: 8 lb per plant. 24 in apart, 50 days, picked continuously.
• Eggplant: 6 lb per plant. 18 in apart, 100 days, picked continuously.
• Cucumber: 5 lb per plant. 12 in apart, 60 days, picked continuously.
• Tomatillo: 5 lb per plant. 24 in apart, 100 days, picked continuously.
• Spaghetti squash: about 5 squash per plant, roughly 20 lb. 36 in apart, 88 days, single harvest.
• Acorn squash: about 5 squash per plant, roughly 10 lb. 30 in apart, 80 days, single harvest.
• Potato: 3 lb per plant. 12 in apart, 90 days, single harvest.
• Hot pepper: 3 lb per plant. 18 in apart, 95 days, picked continuously.
• Sweet potato: 2.5 lb per plant. 14 in apart, 110 days, single harvest.
• Kale: 2 lb per plant. 16 in apart, 60 days, picked continuously.
• Okra: 2 lb per plant. 18 in apart, 55 days, picked continuously.
• Celery: 1.5 lb per plant. 7 in apart, 110 days, single harvest.
• Artichoke, globe: 1.5 lb per plant. 36 in apart, 100 days, picked continuously.
• Pole bean: 1.5 lb per plant. 6 in apart, 65 days, picked continuously.
• Broccoli: 1.2 lb per plant. 18 in apart, 70 days, picked continuously.
• Bush bean: 0.75 lb per plant. 3 in apart, 55 days, picked continuously.
• Basil: 0.5 lb per plant. 8 in apart, 60 days, picked continuously.
• Asparagus: 0.5 lb per plant. 18 in apart, 60 days, picked continuously.
• Lettuce: about 0.4 of a head per plant. 6 in apart, 45 days, single harvest.

Single harvest vs picked all season

This is the distinction that matters most, and almost no yield chart says it out loud.

A potato gives its 3 lb in one afternoon. You dig the plant, the plant is done, and you carry 3 lb to the basement. Same with winter squash, sweet potatoes, celery, and lettuce. The whole yield arrives at once, so you need somewhere to put it and a plan for eating it over months, not days.

A slicing tomato gives its 12 lb spread across 6 to 8 weeks of picking. That is roughly 1.5 to 2 lb a week from one plant. You never face 12 lb of tomatoes at once. Same with peppers, cucumbers, okra, pole beans, and summer squash.

Here is why that trips people up. One summer squash plant gives 8 lb, but it arrives a squash or two at a time over about two months, starting just 50 days in. Three plants means a steady pile landing on your counter every few days with no storage option. Meanwhile 10 potato plants give 30 lb once, which sounds like a lot but is a side dish twice a week for two months and then it is gone.

The test: for continuous crops, ask what you can eat or give away in a week. For single-harvest crops, ask what you can store for a season. Those are two different questions and they give two different plant counts.

Why your real yield will be lower

Be honest with yourself about this chart. Those numbers are what a healthy plant gives in a decent season with steady water, real sun, and reasonable soil. Most first-year gardens do not hit them.

A hot dry stretch during flowering can cut a tomato plant in half. Squash vine borers can end an 8 lb summer squash plant in July at 3 lb. Plants crowded closer than the spacing above shade each other and drop yield across the whole bed. A late frost on a 110-day crop like eggplant or celery can take the season entirely.

So treat the chart as a planning ceiling, not a promise. Assume you will come in under it your first year, and plant a little extra on anything you would be sad to run out of.

Then run the test that actually settles it. Pick one crop, weigh what you bring in from a single plant across the whole season, and write the number on the seed packet. Your yard, your soil, your water habits. After one season you have a real number, and after two you can plant a garden that matches your kitchen instead of a chart.

Get your exact number

Yield per plant answers half the question. The other half is how many plants you need, and that depends on your household, your frost dates, and how much of each crop you actually eat.

The planner does that math. Tell it your ZIP code and who you are feeding, and it works backward from these same per-plant numbers to an exact plant count and the bed space to grow it. You plant 7 tomatoes and 22 potatoes instead of a round guess.
