Can you grow corn in a raised bed?

Yes, you can grow corn in a raised bed. Raised beds are ideal for growing corn because they provide a controlled environment that is easy to manage. Corn requires plenty of nutrients and water, which can be difficult to achieve in traditional garden beds. In raised beds, you can control the soil quality and drainage, which helps to optimize the growth of your corn plants.

Step 1: Choose the right location

Corn requires full sun to grow, so choose a location that receives at least 6-8 hours of direct sunlight per day. Also, make sure the location is sheltered from strong winds, as corn plants can be easily damaged by strong gusts.

Step 2: Prepare the soil

Corn requires fertile, well-drained soil to grow. You can prepare your raised bed by mixing in compost, manure, or other organic matter to improve soil fertility. The ideal soil pH for growing corn is between 6.0 and 6.8.

Step 3: Plant the corn seeds

Corn is typically planted in rows, but in square foot gardening, it is recommended to plant corn in a grid pattern. This allows for better pollination and maximizes the use of space.

To plant corn seeds, make a hole in the soil with your finger, drop in one or two seeds, and cover it with soil. Space each hole about 12 inches apart, and each row should be spaced about 3 feet apart.

Step 4: Water and fertilize

Corn requires plenty of water to grow, especially during the hot summer months. Be sure to water your corn plants regularly, keeping the soil moist but not waterlogged. Fertilize your corn plants every 2-3 weeks with a balanced fertilizer that is high in nitrogen.

Step 5: Harvest

Corn is ready to harvest when the silks turn brown and the kernels are plump and juicy. Simply pull back the husks and pick the ears of corn by hand. If you are unsure whether your corn is ready to harvest, peel back a small section of the husk and check the kernels.

How many plants can I grow in a 20×20 room?

Assuming you are using square foot gardening and growing corn, you can plant approximately 90 corn plants in a 20×20 room. This assumes that each plant is given 1 square foot of space to grow. However, keep in mind that corn plants require a lot of space and can grow quite tall, so a 20×20 room may not be the ideal size for growing corn.

How many corn seeds per hole?

When planting corn seeds in a raised bed, you’ll want to space them about 6-8 inches apart. This means that you can plant between 9 and 16 corn seeds per square foot, depending on how close you space them.

However, it’s important not to plant too many corn seeds in each hole. Overcrowding can lead to stunted growth and lower yields. Instead, aim to plant no more than 2-3 corn seeds per hole, and thin them out once they start to germinate. Thinning involves removing the weaker seedlings and leaving the strongest ones to grow.


In conclusion, growing corn in square foot gardening can be a rewarding and enjoyable experience for gardeners who are looking to maximize their growing space. While corn can take up a lot of room, using the square foot gardening method can help to minimize the amount of space needed while still producing a healthy and bountiful harvest.

To successfully grow corn in square foot gardening, it is important to choose a suitable variety of corn, prepare the soil properly, and space the plants appropriately. By following these guidelines and providing the plants with adequate water and nutrients, gardeners can enjoy fresh, delicious corn throughout the growing season.

Overall, square foot gardening is a great way to grow corn and other crops in a small space. It allows gardeners to make the most of their available growing area while also promoting healthy soil and reducing the need for excessive watering and fertilization. Whether you are an experienced gardener or just starting out, square foot gardening can help you to create a productive and sustainable garden.
