Purple Splendor on the Roof: Your DIY Guide to Growing Purple Corn on the Rooftop

Hey everyone! Have you ever dreamed of growing your own colorful harvest right in the middle of the city? I have! And what could be more exciting than Purple Corn, also known as purple maize? This corn is not only beautiful to look at but also rich in antioxidants and just super cool. In this article, I’ll show you how you can grow this eye-catcher on your roof. Don’t worry, it’s easier than you think!

What You Need: The Shopping List

Before we get started, we need a few things. Here’s a list so you have everything at hand:

• Purple Corn Seeds: You can get these online or in well-stocked garden centers. Look for organic quality!
• Large Planters: Tubs with at least 45 liters capacity per plant are best. Corn needs space!
• High-quality Potting Soil: A mixture of garden soil, compost, and a little sand is ideal.
• Drainage Material: Expanded clay, gravel, or terracotta shards for the bottom of the planters.
• Organic Fertilizer: Corn is a heavy feeder, so we’ll need some support.
• Watering Can or Hose: For regular watering.
• Support Stakes: Especially important if your roof is windy.
• Pruning Shears: For removing side shoots.
• Gloves: To keep your hands clean.
• Sunny Location: Corn loves the sun!

Preparation is Everything: Preparing the Planters

Before we put the seeds in the ground, we need to prepare the planters. This is super important for success!

1. Lay Drainage: First, we fill the bottom of the planters with a layer of drainage material. This prevents waterlogging, which corn really dislikes. A layer of about 5-10 cm is perfect.
2. Fill with Soil: Now, the potting soil goes into the tubs. Fill them to about 5 cm below the rim. This gives us enough space for watering.
3. Moisten the Soil: Lightly water the soil before planting the seeds. This gives them a good start.

Sowing: The Start of a Purple Adventure

Now comes the exciting part: Sowing!

1. Prepare Seeds: Soak the Purple Corn seeds in lukewarm water for about 12-24 hours. This speeds up germination.
2. Sow: Make small holes in the soil, about 2-3 cm deep. Place 2-3 seeds in each hole. This increases the likelihood that at least one will germinate.
3. Close Holes: Carefully cover the seeds with soil and press them down lightly.
4. Water: Gently water the soil so the seeds are not washed away.
5. Location: Place the planters in a sunny spot on your roof. Corn needs at least 6 hours of sun per day.

Care: So the Corn Grows Magnificently

While corn is relatively easy to care for, it still needs a little attention.

1. Watering: Water regularly, especially during dry periods. The soil should always be slightly moist, but not wet. It’s best to water in the morning or evening to avoid evaporation.
2. Fertilizing: Corn is a heavy feeder, so it needs regular fertilizer. Start fertilizing about 4 weeks after germination. Use an organic fertilizer specifically suitable for vegetables. Fertilize every 2-3 weeks.
3. Remove Side Shoots: Purple Corn develops side shoots, also known as “suckers.” These unnecessarily sap the plant’s strength. Remove them regularly with pruning shears.
4. Support: If your roof is windy, you should stabilize the corn plants with support stakes. This prevents them from toppling over.
5. Pest Protection: Watch out for pests such as aphids or corn borers. In case of infestation, you can use biological pest control agents.

Pollination: The Key to Corn Cob Formation

Corn is wind-pollinated. This means that pollen from the male flowers (the “tassels” at the top of the plant) must reach the female flowers (the “silks” on the corn cobs).

1. Support Pollination: If it’s windless, you can support pollination by gently shaking the plants or transferring pollen from the male to the female flowers with a brush.
2. Multiple Plants: It’s best to plant several corn plants next to each other to facilitate pollination.

Harvest: The Reward for Your Efforts

After about 80-100 days, it’s time: The Purple Corn cobs are ripe!

1. Recognize Ripeness: The corn cobs are ripe when the husks are dry and brown and the kernels are plump and firm.
2. Harvest: Carefully break the corn cobs from the plant.
3. Usage: You can eat the Purple Corn cobs fresh, grill them, boil them, or process them into flour. The flour is excellent for tortillas, bread, or polenta.

Extra Tips for Successful Cultivation

Here are a few additional tips that will help you maximize your Purple Corn harvest:

• Observe Crop Rotation: Do not grow corn in the same location every year. Rotate crops to prevent diseases and pests.
• Improve Soil: Before sowing, mix compost or organic fertilizer into the soil to improve it.
• Mulch: Mulch the soil around the corn plants with straw or grass clippings. This retains moisture in the soil and suppresses weeds.
• Regular Inspection: Regularly check the plants for pests and diseases. The earlier you identify a problem, the easier it is to fix it.
• Don’t Give Up: Sometimes it doesn’t work out the first time. Don’t be discouraged and just try again!

Frequently Asked Questions (FAQ)

1. What kind of soil is best for growing purple corn on a rooftop?

Purple corn thrives in well-draining, fertile soil. A mix of potting soil, compost, and perlite is ideal for container gardening on a rooftop. The potting soil provides a good base, the compost adds essential nutrients, and the perlite improves drainage and aeration. Aim for a slightly acidic to neutral pH level (around 6.0 to 7.0). You can test the pH of your soil using a home testing kit or by sending a sample to a local agricultural extension office. Consider adding slow-release fertilizer to the soil mix to provide a steady supply of nutrients throughout the growing season.

2. How much sunlight does purple corn need to grow successfully on a rooftop?

Purple corn requires at least 6-8 hours of direct sunlight per day to thrive. Choose a location on your rooftop that receives ample sunlight throughout the day. If your rooftop is partially shaded, try to position your containers so that the corn receives the most sunlight during the hottest part of the day. You can also use reflective materials, such as white paint or aluminum foil, to bounce sunlight onto the plants. If you live in a particularly sunny area, you may need to provide some afternoon shade to prevent the plants from overheating.

3. How often should I water my purple corn plants on a rooftop?

Watering frequency depends on several factors, including the weather, the size of your containers, and the type of soil you’re using. Generally, you should water your purple corn plants whenever the top inch of soil feels dry to the touch. Water deeply, ensuring that the water reaches the roots. Avoid overwatering, as this can lead to root rot. During hot, dry weather, you may need to water your plants daily. In cooler, wetter weather, you may only need to water them every few days. A good rule of thumb is to check the soil moisture regularly and adjust your watering schedule accordingly.

4. What are some common pests and diseases that affect purple corn, and how can I prevent them?

Common pests that can affect purple corn include corn earworms, aphids, and spider mites. Diseases include corn smut and various fungal infections. To prevent pests and diseases, practice good garden hygiene. Remove any dead or decaying plant matter from around your plants. Water your plants at the base to avoid wetting the foliage, which can create a favorable environment for fungal growth. Inspect your plants regularly for signs of pests or diseases and take action promptly. You can use organic pest control methods, such as insecticidal soap or neem oil, to control pests. For fungal diseases, you can use a copper-based fungicide. Crop rotation can also help to prevent soilborne diseases.

5. How do I know when my purple corn is ready to harvest?

The timing of harvest depends on the specific variety of purple corn you’re growing and what you intend to use it for. For fresh corn on the cob, harvest when the silks have turned brown and dry and the kernels are plump and milky. You can test the kernels by piercing one with your fingernail; if a milky liquid squirts out, it’s ready to harvest. For dried corn, leave the ears on the stalks until the husks are completely dry and brown. The kernels should be hard and dry to the touch. You can also check the moisture content of the kernels using a moisture meter. The ideal moisture content for storing dried corn is around 13-14%.

6. Can I grow purple corn in containers if I don’t have a rooftop?

Yes, you can absolutely grow purple corn in containers even if you don’t have a rooftop. The key is to choose large enough containers (at least 10-15 gallons) and provide adequate sunlight and water. You can grow purple corn on a balcony, patio, or even indoors with the help of grow lights. Just make sure that the containers have drainage holes to prevent waterlogging.

7. What are some creative ways to use my homegrown purple corn?

The possibilities are endless! You can use your homegrown purple corn to make purple corn tortillas, polenta, cornbread, and even purple corn beer or ice cream. You can also dry the kernels and grind them into flour for baking. The dried husks can be used for crafts or as mulch in your garden. And of course, you can simply enjoy the beautiful purple ears as ornamental decorations. The vibrant color of purple corn adds a unique touch to any dish or décor.

8. Is purple corn more nutritious than regular yellow corn?

Yes, purple corn is generally considered to be more nutritious than regular yellow corn. It is particularly rich in anthocyanins, powerful antioxidants that have been linked to a variety of health benefits, including reduced risk of heart disease, cancer, and diabetes. Purple corn also contains higher levels of other nutrients, such as fiber, vitamins, and minerals, compared to yellow corn.

9. Where can I find purple corn seeds to start my rooftop garden?

You can find purple corn seeds at many garden centers, nurseries, and online seed retailers. Look for reputable seed companies that specialize in heirloom or open-pollinated varieties. Some popular varieties of purple corn include ‘Blue Hopi,’ ‘Cherokee Blue,’ and ‘Oaxacan Green.’ Be sure to choose a variety that is well-suited to your climate and growing conditions.

10. How can I ensure successful pollination of my purple corn plants on a rooftop?

Corn is wind-pollinated, so it’s important to ensure that there is adequate air circulation around your plants. If your rooftop is sheltered from the wind, you may need to hand-pollinate your corn plants. To do this, gently shake the tassels (the male flowers at the top of the plant) over the silks (the female flowers that emerge from the ears). You can also collect pollen from the tassels using a small brush and then apply it to the silks. Repeat this process every day for several days to ensure that all of the silks are pollinated. Planting your corn in blocks rather than rows can also improve pollination rates.
