Can You Grow Zucchini in a Pot?

Zucchini plants grow quite well in pots big enough for their root system. Bush zucchinis thrive in a 5- to 10-gallon pot. Vining zucchini varieties need a 30-gallon container because they have much longer taproots. No matter the variety, all zucchini plants should have their own container. Expect to water your potted plants more often than ones in the ground. Relatively early harvests will help the potted plants thrive and ensure you get tender zucchini.

How Do You Grow Zucchini in a Pot?

Growing zucchini in containers or pots works just as well as putting them in the ground. You just have to follow five quick and easy steps to give your zucchini plants the best chance to thrive.

  • Prepare your containers
  • Use high-quality soil
  • Plant your zucchini seeds
  • Put supports in place
  • Check on your plants each day

From there, it’s just a matter of watching your plants grow and harvesting the zucchini.

Prepare the Pots

Select one pot for each zucchini plant you plan to grow. 5-gallon pots work best for bush varieties. If growing vining zucchini, use a 30-gallon pot instead. Wipe down each container with a 30-to-1 mix of water to bleach unless you’re using new pots. Thoroughly rinse out the pots and put them in your planting area.

Use Quality Soil

Zucchini plants need high-quality potting soil to grow well in containers. Choose a potting soil mix with compost, peat moss, and vermiculite to promote excellent drainage. Do not put any rocks, water bottles, or other filler materials in the bottom of the pots. Instead, loosely fill the containers almost to the top with this organic soil mix. You want any zucchini in pots to have a well-draining potting mix to thrive in.

Plant Your Seeds

Scatter 4–6 zucchini seedlings on top of the potting soil in each container. Don’t let any of the seeds get closer than four inches from the rim of the pot. Make sure the seeds sit flat against the potting soil. Then, use your finger to push each one about 1 inch (2.5 cm) down into the soil. Water each pot until the soil looks moist but not waterlogged. Wait until the seedlings pop up. Then, thin them down to just one healthy plant per pot.

Add Supports

Put in a good support system to keep your zucchini plants from tipping over in their pots. You can set them next to a chain-link fence or trellis if you have one available. Otherwise, just put this tomato cage in the pot. The supports must go in before the root system gets too big. Start tying the zucchini plant to the support when it reaches 6 inches (15 cm) in height. Add another tie every three inches to keep the plant growing vertically.

Check Plants Daily

Daily check-ins are a must when growing zucchini in pots. The soil dries out much faster in a pot, especially in hot, sunny weather. To see if your plants need water, push your finger about 2 inches deep (5 cm) into the potting soil. Water the plants thoroughly if the soil feels dry to that depth. You want moist soil. Look your plants over to check for signs of pests, disease, and nutrient deficiencies. Treat any problems right away to keep your potted zucchini healthy through the growing season.

Keep in mind that once the fruit sets, the zucchini fruit grows very fast. At each check-in, harvest any zucchini over 5 inches (13 cm) long. Removing the ripe fruit at that stage will ensure they’re tender and delicious. The plant can they be ready for more fruit production.

How Many Zucchinis Can You Grow in a Pot?

One zucchini per pot is plenty. Zucchini plants have a large root system and broad plant leaves. So, they like to have a lot of room to spread out. When planting seeds, always scatter a bunch to make sure something germinates. Once the seedlings pop up, thin them down to just one plant per pot for the best results.

  • Zucchini plants each need their own pot to grow to their full potential.
  • Even a small zucchini variety needs its own pot.
  • Start several seeds in each pot to ensure at least one seedling grows in every container.
  • As the plants mature, their broad leaves and large root system will take up the full pot.
  • Growing multiple plants in one pot increases the risk of poor growth, pests, and diseases.

Allowing the seeds to grow without thinning will increase the risk of pests and diseases. The plants won’t grow to their full potential either. You’ll get the best results by providing space to each plant.

Can You Plant 2 Zucchinis in a Pot?

Planting two zucchinis in a single pot is a bad idea. The plants will compete for water, nutrients, and sunlight. Zucchini plants need their own pot to truly thrive and produce big harvests.

  • Zucchinis need to be kept to one plant per container.
  • Two zucchini plants in one pot will compete for resources.
  • A vining variety of zucchini can grow very large—a single pot for two plants simply isn’t big enough.
  • Thin seedlings early or their roots will get tangled together.

Plan to thin out the seedlings early to keep the roots from getting tangled up. If you wait too long, it’ll be impossible to separate the plants without damaging their roots. As a rule, once the seedlings have produced their first true leaves, uproot all but the strongest, most productive plant.

Can You Grow Zucchini in 5 Gallon Buckets?

Bush zucchini will happily grow in a food-grade 5-gallon bucket. Vine types need a much larger pot, at least 30 gallons in capacity. In order to be used as a zucchini pot, your 5-gallon bucket will need drainage holes in the bottom. Use a ½ inch drill bit (13 mm) and drill 5–8 holes in the bottom of the bucket for water to drain out.

  • Bush zucchini thrive in 5-gallon buckets.
  • Vining zucchini need 30-gallon containers to allow for proper root growth.
  • 5-gallon buckets need drainage holes to ensure proper drainage for your plants.
  • Use a drill and ½-inch drill bit (13 mm) to drill 5–8 holes in the bottom of the bucket.
  • Reuse 5-gallon buckets each growing season to reduce waste.
  • Always clean out buckets properly to create optimal growing conditions.

Plan to reuse the buckets each year to keep containers out of the landfill. Before putting the pots away, remove the dead plants and soil. Then, wash the container with drainage holes with dish soap and water. Finally, sanitize the buckets with a 30-to-1 water to bleach solution at the beginning of the next growing season.

Growing Zucchinis in a Pot

Growing zucchinis in a pot is easy and rewarding when you take the right approach. You just need a 5-gallon bucket for bush varieties and 30-gallon containers for vining types.

  • Zucchini happily grow in containers big enough to fit their large roots.
  • Only grow one zucchini in each container to avoid overcrowding your plants.
  • Check on your potted zucchini on a daily basis to help them grow big and strong.

Grow one zucchini in each pot for the best results. You should start multiple seedlings in every pot, however, then remove all but the strongest seedling. Plan to check your plants daily to ensure they get enough water and stay safe from pests, diseases, and other problems. Once the plants produce fruit, harvest your zucchini when they reach 5–7 inches long (13–18 cm).
