Table of Contents

Corn is a staple food worldwide and has been cultivated by humans for thousands of years. Typically, corn is grown in large fields, but if you live in an apartment or have limited space, worry not! You can still enjoy the taste of fresh corn by growing it in pots! This may seem like a daunting task, but with the right setup, it is possible to produce fresh ears of corn on your balcony or patio.

Why Growing Corn in Pots is Possible?

Growing corn in pots is becoming increasingly popular as people are transitioning to smaller living spaces such as apartments, condominiums, or homes with limited space. Growing corn in pots also allows you to have control over the soil and other growing conditions, which contributes to better crop yields. By opting to grow corn in pots, you can choose the location and provide suitable soil components, sunlight, water, and fertilizer according to your preferences.

Benefits of Growing Corn in Pots

Growing corn in pots offers many benefits such as:

• No need for large gardening areas
• Greater flexibility in choosing where to place the pot
• Consistent moisture levels
• Fertilizer applications only where needed
• Shorter time between planting and harvesting
• Reduction in plant diseases
• Pest control is easier

Now that we know the benefits of growing corn in pots, let's dive into the steps required to get started!

Choosing the Right Container and Soil

When selecting containers and soil for corn plants, consider the following factors:

Container Size & Depth

When selecting a container, always remember that the size of your container determines the size of your corn plant. Ideally, choose pots that are 12 inches deep and at least 16 inches across. This will give your corn plants plenty of room to develop their roots and support the stalks.

Soil Requirement

Corn plants require well-drained soil that is rich in organic matter. Fill the bottom of the container with gravel or pebbles as drainage layer, then add a mix of compost, vermiculite, and perlite. Choose good quality potting soil that has plenty of organic matter, and make sure that you have a well-aerated mixture.

Selecting Corn variety and Planting Time

Selecting the right corn variety for growing in pots is essential. Choose short varieties of sweet corn seeds such as "Golden Bantam," "Honey and Pearl," or "Ambrosia." These hybrid plants grow no more than 5-6 feet tall and are suitable for small pots.

Planting Season

The best time to plant corn seeds is during late spring when the temperature is between 60 °F to 95°F. Corn seeds take about six to eight weeks to mature from the seedling stage to the point where they can be transplanted into larger containers.

Seed Planting Techniques

Plant seeds directly into the soil by making a hole 1 inch deep and placing two seeds in each gap. Once the seeds have germinated, remove the weaker of the two plants to obtain one robust plant per hole. Corn plants prefer bright light so select a sunny area for placement of your containers.

Corn care and Maintenance in Pots

Following the below guidelines leads to strong and healthy plants:

Watering and fertilizing requirements

Corn requires regular watering, especially in the summer season when temperatures are high. Consistent moisture is the most important factor that can lead to better crop yield. In addition, provide regular feedings with organic fertilizer for optimal growth. Feed corn plants once a week with balanced liquid fertilizers such as fish emuon, manure tea or seaweed extract at the start of flowering.

Light & Temperature requirements

Corn requires sunlight to grow, indirectly it needs 8-10 hours of sunlight per day in early life stage. The ideal temperature for corn growth and development is between 60°F to 95°F. Make sure to adjust the location according to where it can receive full daily sun exposure.

Pest Control Measures

Pests such as aphids, squash bugs, and cutworms can be problematic for growing corn plants in pots. Use organic pest control solutions such as garlic spray or diatomaceous earth sprays to keep them away. Check plants regularly and remove any yellow or diseased looking leaves to keep diseases from spreading.

Harvesting and Storing Corn in Pots

Harvesting your homegrown corn in pots is an exciting and rewarding experience. Let's learn about when and how to do this:

When to harvest?

Corn generally takes around 70-90 days to mature, depending on environmental factors. Monitor the growth, by feeling for small nubs or bumps that emerge near the ear of corn. Once these bumps fill out and plump up, then the ears ready to be picked. The silks turn brown and shriveled when they dry out and indicate the perfect time to harvest the corn. You may get mature, ripe corn anywhere from 17 – 23 weeks after sowing seeds.

How to store Corn?

Fresh corn can last anywhere from five to seven days if stored properly. Keep the husks on and immerse the ears in a large bowl of ice-cold water to ensure moistness. After soaking the corn, wrap with cling film and store it inside the refrigerator. If you're seeking longer storage than blanch fresh corn in boiling water before freezing them.

Growing corn in containers may need some care and effort, but with the right setup, it can be achieved effortlessly. There is nothing quite like going to your balcony or patio and harvesting your first ears of fresh and sweet corn! Now that you know more about how to grow corn in pots, it's time to give it a try.

What type of container is suitable for planting corn?

Choose a 12-inch-deep pot with at least 16 inches width that has excellent drainage on the bottom.

How many corn plants can be grown in one pot?

It is best to plant only one corn plant per container to ensure ample space for roots development.

Can you Grow Corn in Hanging Baskets?

Growing corn in hanging baskets isn't recommended since the plants require plenty of space and heavy infrequent watering. A hanging basket may not be stable enough to prevent spilling of water and soil.

What are the Common Problems when growing corn in pots?

Can I regrow Corn from kitchen scraps?

How much fertilizer does corn need when grown in pots?

Corn growing in conditions without soils may have more considerable nutrient needs. Use a balanced liquid fertilizer once a week for best results, such as fish emuon, manure tea or seaweed extract at the start of flowering stage until picking period.

Do I need to pollinate Corn planted in pots?

Corn plants require pollination to produce cobs, but it is not uncommon for the wind and insects to carry pollen from one plant to another. Thanks to the abundance of space in large fields! However, hand-pollinating increases productivity in situations where diversity exists since cross-pollination between corn plants of mixed traits could cause inferior results.
