I have some small-space vegetable gardening tips for anyone living in an apartment, duplex, or condo, and who has a patio or balcony.

Sun, Water, & Soil:

Vegetables need six or more hours of sun each day. Lettuce and broccoli will survive in light shade.

Vegetables need regular watering. The quickness of their growth depends on it. So you can’t rely on rainfall alone with vegetables in containers, as they will heat up quickly.

Vegetables also need rich soil, so it is wise to add organic matter. Even taste can be affected by soil quality.

If you can provide sun, water, and good soil, you can have a thriving vegetable garden.

How Much Space Do You Need?

Even a few pots can provide you with veggies. You can try this vegetable size tool to get a better idea.

In terms of container size, the larger your container is, the easier it will be to maintain. The more soil a container holds, the more moisture it will retain. The key is to choose the right size container for the plant you want to grow and ensure it has proper drainage.

The space you’ll need for a container vegetable garden depends on the types of vegetables you want to grow. Generally, larger containers are better for most vegetables, especially those with deeper roots, such as tomatoes and squash. 

Smaller containers can be used for shallow-rooted vegetables like lettuce. A good starting point is a 5-gallon container for most vegetables. But some, like tomatoes, may benefit from larger 10-15-gallon pots. 

Most vegetables need at least 12 inches of soil to grow well, but larger vegetables will require more space. To maximize space, try planting low-growers and tall climbers together in the same container. 

When To Grow Vegetables:

Lettuce will grow in the cooler months, but will bolt when it gets hot. However, you can keep lettuce growing all summer if you plant tall plants to shelter lettuce from the sun.

If you don’t damage the lettuce crown, more will grow and give you a steady supply of lettuce.

Most seed packets will give you the mature size of the plant. For containers, look for plants that say Compact or Petite. This does not mean that the veggies will be small.

Vegetables that harvest early, such as spinach, radishes, and peas, could be mixed with slower-growing plants like broccoli and peppers. Bell peppers grow up instead of out. So they’re perfect for containers or a small plot.

When the cooler-weather vegetables wane, replace them with warm-weather growers.

Warm-season vegetables are not frost-tolerant and can sustain significant damage when exposed to temperatures below freezing. Some may even show damage at temperatures slightly above freezing. 

Warm-season vegetables should not be planted until the danger of frost has passed. Most are ready for harvest by mid to late summer, and those vegetables that produce continuously can be harvested regularly until the first frost.

Warm Season Vegetable Plants:

• Squash
• Tomatoes
• Peppers
• Cucumbers
• Green Beans
• Sweet Potatoes
• Okra
• Corn
• Eggplant
• Melons
• Tomatillos
• Asparagus Beans (Yard Long Beans)
• Summer Greens
• New Zealand Spinach

Cool Weather Vegetables Plants:

In spring, or looking forward to fall, you can plant cool-weather plants in your garden.

Vertical Space Vegetable Gardening:

Take advantage of vertical space if you have a small garden. When you can’t grow out, then grow up. When you grow vertically, you increase yield, improve pest management, create privacy from neighbors, and make harvesting easier.

Growing vertically helps reduce problems such as leaf fungus and fruit rot because it improves air circulation.

You can train some vegetables up a trellis. They include cucumbers, squash (acorn or butternut), tomatoes, green beans, and peas.

Veggies you can train up a trellis are cucumbers, squash (acorn or butternut), tomatoes, green beans, and peas.

Small Space Gardens Can Yield Lots Of Veggies:

Just because you live in a small space doesn’t mean you can’t have a vegetable garden. As long as you have a patio or balcony and containers with access to water, you can grow vegetables.

If the surface is cement, however, the pots’ bottoms will dry out more quickly. Also, cement itself can be porous, allowing for further water loss.

Container vegetable gardens can have higher yields than your average vegetable garden because the soil is above ground and warms up much quicker during the day. Warmer soil promotes root growth and helps your plants grow faster.
