5 Techniques for a More Productive Vegetable Garden

Here are give surefire ways to maximize the output of your vegetable garden.


Whether you're a first-time vegetable gardener or have twenty years of experience, we all can agree that there is nothing better than a monumental harvest at the end of the season. With just a few secrets and some free time, you'll have a wonderfully bountiful output this year.

Start Intensive Planting Beds

The surest way to increase the yield from a vegetable garden is to reduce the space between plants. The idea is to plant wide bands, thus reducing the amount of ground devoted to paths.

To start an intensive garden, make a bed of any length, but limit its width to 3 to 4 feet across so you can reach the center of the bed from either side. Although it's not necessary to box in the bed, this is a good idea. When you enclose a bed with vertical boards, it's not only neater, but the soil won't collapse onto the paths. It also will be much easier for you to install row covers or erect supports for vertical growing.

Go Vertical

You'll find that some vegetables grow better with support. They do well on trellises, fences, and other structures. By growing up instead of out, your garden will produce more per square foot. Vegetable plants grown on a support also tend to suffer fewer disease problems.

  • Tomatoes. Choose indeterminate varieties, which continue to grow and produce over a long period, often until frost. Grow tomatoes in wire cages or support them by tying them to 7-foot-tall wood stakes driven 2 feet into the ground. Cage-grown tomatoes require minimal attention but are more prone to fungal diseases. Tomatoes grown on stakes benefit from being pruned to a single stem; this means constantly pinching out new branches that arise in the crotch between the main stem and a leaf.
  • Pole beans. Although they take longer to mature than bush-type beans, pole beans produce over a longer period. Train pole beans up tall wooden poles or a tepee of sturdy bamboo.
  • Cucumbers. Vine-type cucumbers (as opposed to the bush varieties) do well on fences and trellises. Vertically grown cucumber fruits also tend to be straighter and more uniform than those grown on the ground.
  • Snap Peas. These super-sweet edible pod peas are among the most productive vegetables in the spring garden. By selecting tall vining varieties (such as the original Sugar Snap pea), you can easily grow them on 5- to 6-foot-tall mesh trellises. Pick carefully to avoid damaging the brittle vines.
  • Melons and winter squash. These long-season crops require heavy-duty support if you choose to grow them vertically. Larger varieties may even need slings made of cloth to support the fruit. You'll also need to tie the vines to the support using strips of cloth; avoid string or wire, which can cut into the vines.

Extend the Season

Picking Sweet Corn

There are two types of succession planting, and both are super easy!

The simplest form is to plant varieties that produce for a limited amount of time over a period of weeks. For example, instead of planting 40 corn seeds at once, you could plant 10 corn seeds a week over a four-week period. This will give you corn for a month instead of all at once.

Another example is to plant bush beans every two weeks to ensure a continuing supply. If you want to have three crops, plant one-third of the bed every two weeks. Other crops that benefit from this type of succession planting include corn, carrots, radishes, and heading lettuce.

The second type of succession planting takes a little more planning. It means that when a crop is done producing in your garden you take it out and plant something else in that spot.

For example, after your peas are done for the season, pull out the vines and plant cucumbers in their place. The key to success of this system is to have a new batch of seeds or seedlings ready to go when the first crop is done. This system works best when you are starting with vegetables that do well in cool weather, but not so well in summer's heat. In addition to peas, you can use this technique with lettuce, spinach, and radishes.

A related technique is to plant several varieties with different maturities. For example, you might plant an early-maturing tomato such as 'Early Girl' at the same time as a main-season beefsteak variety.

Start Interplanting

This technique takes advantage of the fact that some vegetables grow quickly while others take their time. For example, if you plant carrots and radishes together, you can harvest the radishes in about 30 days, when the carrots will still be quite small. Another option is to combine a vertical vegetable (like tomatoes) with a low-growing crop (like melons).

Some interplanting combinations that work well include:

  • Growing sprawling melons and squash under stake-grown tomatoes.
  • Surrounding corn with lettuce or peas with radishes.
  • Combining quick and slow vegetables such as lettuce with tomatoes, beets with pole beans, spinach with winter squash, leeks with sweet potatoes, and radishes with sweet corn.
