What You’ll Need: The Essential Supplies
Before we dive in, let’s gather our supplies. This is crucial for a smooth and successful corn-growing experience.
* Concrete Blocks: These are the foundation of our corn planters. I recommend using blocks that are at least 8 inches tall and wide. The more space you give the roots, the better. You’ll need enough to create the number of planters you want. I usually aim for at least 4 blocks per planter to create a decent-sized growing area.
* Heavy-Duty Landscape Fabric: This will line the inside of the concrete blocks, preventing soil from escaping and keeping the roots contained.
* High-Quality Potting Mix: Don’t skimp on this! Corn needs nutrient-rich soil to thrive. Look for a mix that’s well-draining and contains plenty of organic matter.
* Corn Seeds: Choose a variety that’s suitable for your climate and growing season. Sweet corn is always a popular choice! Make sure to buy from a reputable source to ensure good germination rates.
* Slow-Release Fertilizer: Corn is a heavy feeder, so a slow-release fertilizer will provide a steady supply of nutrients throughout the growing season. Look for a fertilizer specifically formulated for vegetables.
* Watering Can or Hose: Essential for keeping your corn plants hydrated.
* Gloves: Protect your hands from the concrete and soil.
* Measuring Tape: To ensure accurate spacing of the concrete blocks.
* Shovel or Trowel: For filling the concrete blocks with soil.
* Safety Glasses: To protect your eyes from dust and debris.
Building Your Concrete Corn Planters: A Step-by-Step Guide
This is where the magic happens! We’ll transform those plain concrete blocks into thriving corn planters.
1. Choose Your Location: Corn needs at least 6-8 hours of direct sunlight per day. Pick a spot that gets plenty of sunshine. Also, consider the mature height of your corn plants. You don’t want them blocking sunlight from other plants or creating an obstruction.
2. Prepare the Ground: Clear the area where you’ll be placing the concrete blocks. Level the ground as much as possible to ensure the planters are stable.
3. Arrange the Concrete Blocks: Decide on the shape and size of your planters. You can arrange the blocks in a square, rectangle, or even a circle. I prefer a rectangular shape, as it allows for good airflow between the plants. Leave a small gap between the blocks for drainage.
4. Line the Planters with Landscape Fabric: Cut the landscape fabric to size, allowing for plenty of overlap. Line the inside of each planter, making sure to cover all the concrete surfaces. This will prevent the soil from leaching out and protect the roots from direct contact with the concrete. Secure the fabric with staples or by folding it over the top edge of the blocks.
5. Fill with Potting Mix: Now it’s time to fill the planters with your high-quality potting mix. Leave a few inches of space at the top to allow for watering. Gently tamp down the soil to remove any air pockets.
6. Add Slow-Release Fertilizer: Follow the instructions on the fertilizer package to determine the correct amount to use. Mix the fertilizer thoroughly into the top few inches of the potting mix.
Planting Your Corn Seeds: From Seed to Stalk
Now for the exciting part – planting the corn!
1. Determine Planting Density: Corn needs to be planted in blocks or rows to ensure proper pollination. I usually plant my corn seeds about 6-8 inches apart within the row, and the rows about 12-18 inches apart. This allows for good airflow and sunlight penetration.
2. Plant the Seeds: Use your finger or a small trowel to create holes about 1-2 inches deep. Place 2-3 corn seeds in each hole. This increases the chances of germination.
3. Cover the Seeds: Gently cover the seeds with potting mix and lightly water the soil.
4. Label Your Planters: It’s always a good idea to label your planters with the type of corn you’re growing and the date you planted the seeds. This will help you keep track of your progress.
Caring for Your Corn Plants: Nurturing Your Crop
Consistent care is key to a bountiful corn harvest.
1. Watering: Corn needs consistent moisture, especially during germination and the early stages of growth. Water deeply whenever the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.
2. Fertilizing: Corn is a heavy feeder, so you’ll need to supplement the slow-release fertilizer with additional feedings throughout the growing season. I usually use a liquid fertilizer every 2-3 weeks, following the instructions on the package.
3. Weeding: Keep the planters free of weeds, as they can compete with the corn plants for nutrients and water. Hand-pull any weeds that appear.
4. Pollination: Corn is wind-pollinated, so it’s important to ensure good airflow around the plants. If you’re growing corn in a confined space, you may need to hand-pollinate the plants. To do this, gently shake the tassels (the male flowers at the top of the plant) to release the pollen. Then, use a small brush to transfer the pollen to the silks (the female flowers that emerge from the developing ears of corn).
5. Pest Control: Keep an eye out for common corn pests, such as corn earworms and aphids. If you notice any pests, treat them with an appropriate insecticide or organic pest control method. I prefer using organic methods whenever possible.
6. Support: As the corn plants grow taller, they may need some support to prevent them from falling over. You can use stakes or trellises to provide support.
Harvesting Your Corn: The Sweet Reward
The moment you’ve been waiting for!
1. Check for Ripeness: Corn is typically ready to harvest about 60-100 days after planting, depending on the variety. The silks will turn brown and dry, and the ears will feel plump and full.
2. Harvest the Ears: To harvest the ears, gently pull them down and twist them off the stalk.
3. Enjoy Your Harvest: Freshly harvested corn is best enjoyed immediately. You can grill it, boil it, roast it, or use it in your favorite recipes.
Troubleshooting: Common Issues and Solutions
Even with the best planning, you might encounter some challenges. Here are a few common issues and how to address them:
* Poor Germination: If your corn seeds aren’t germinating, make sure the soil is warm enough (at least 60°F). You can also try soaking the seeds in water for 24 hours before planting to improve germination rates.
* Yellowing Leaves: Yellowing leaves can indicate a nutrient deficiency. Try fertilizing the plants with a balanced fertilizer.
* Stunted Growth: Stunted growth can be caused by a variety of factors, including poor soil, lack of sunlight, or pest infestations. Make sure your corn plants are getting enough sunlight, water, and nutrients.
* Poor Pollination: If your corn ears aren’t filling out properly, it could be due to poor pollination. Try hand-pollinating the plants to improve pollination rates.
Why Concrete? The Benefits of Block Gardening
You might be wondering why I chose concrete blocks in the first place. Here’s why I think it’s a great option:
* Space-Saving: Concrete blocks allow you to create raised garden beds in a small space. This is perfect for urban gardeners who don’t have a lot of yard space.
* Improved Drainage: Raised beds provide better drainage than in-ground gardens, which can be especially beneficial in areas with heavy clay soil.
* Soil Control: You have complete control over the soil in your concrete block planters. This allows you to create the perfect growing environment for your corn plants.
* Pest Control: Raised beds can help to deter some pests, such as slugs and snails.
* Aesthetic Appeal: Concrete block planters can add a touch of modern style to your garden.
