Growing Kale in Bottles: A Fun and Space-Saving DIY Project
Hey there, fellow gardening enthusiasts! Are you short on space but still craving fresh, homegrown kale? Well, I’ve got the perfect DIY project for you: growing kale in bottles! It’s a fantastic way to recycle, save space, and enjoy delicious, nutritious greens right at your fingertips. I’ve been doing this for a while now, and I’m excited to share my secrets with you. Let’s get started!
What You’ll Need
Before we dive in, let’s gather all the necessary materials. Trust me, having everything ready beforehand will make the whole process much smoother.
* **Plastic Bottles:** The star of the show! I usually use 2-liter soda bottles or larger water bottles. Make sure they’re clean and free of any residue. You can also use bigger bottles like gallon jugs for even more kale!
* **Kale Seeds or Seedlings:** You can start from seeds or buy small kale seedlings from your local nursery. I personally prefer starting from seeds because it’s more rewarding to watch them sprout and grow.
* **Potting Mix:** Use a good quality potting mix that drains well. Avoid using garden soil directly, as it can become compacted in the bottles.
* **Scissors or Utility Knife:** For cutting the bottles. Be careful!
* **Drill or Nail and Hammer:** To create drainage holes.
* **Watering Can or Spray Bottle:** For watering your kale.
* **Optional: Twine or Rope:** For hanging the bottles (if you want a vertical garden).
* **Optional: Gravel or Small Stones:** For drainage at the bottom of the bottles.
Preparing the Bottles
This is a crucial step, so pay close attention. We need to create a suitable environment for our kale to thrive.
1. **Clean the Bottles:** Thoroughly wash the plastic bottles with soap and water to remove any leftover residue. Rinse them well and let them dry completely. This prevents any unwanted chemicals from affecting your kale.
2. **Cut the Bottles:** Decide how you want to orient your bottles. You have a few options:
* **Horizontal Planting:** Cut a large rectangular opening along one side of the bottle, leaving the bottom intact. This creates a trough-like planter. I find this works well for larger bottles.
* **Vertical Planting (Hanging):** Cut the bottle in half horizontally. Invert the top half and place it inside the bottom half, creating a self-watering system (more on this later). You’ll need to drill holes for hanging.
* **Vertical Planting (Stacked):** Cut off the top of the bottle completely. You can then stack multiple bottles on top of each other, creating a tiered garden.
I usually go for the horizontal planting method because it’s simple and provides ample space for the kale to grow. Use your scissors or utility knife carefully to make the cuts. Remember, safety first!
3. **Create Drainage Holes:** This is super important! Kale needs well-draining soil to prevent root rot. Drill or poke several drainage holes in the bottom of the bottle. If you’re using the inverted bottle method, drill holes in the bottom of the inner bottle (the one that holds the soil). I usually make about 4-5 holes, each about ¼ inch in diameter.
4. **Optional: Add Gravel:** Adding a layer of gravel or small stones to the bottom of the bottle can further improve drainage. This prevents the soil from becoming waterlogged. I usually add about an inch or two of gravel.
Planting Your Kale
Now for the fun part – planting the kale!
1. **Fill with Potting Mix:** Fill the prepared bottle with high-quality potting mix. Leave about an inch or two of space at the top. Gently pat down the soil to remove any air pockets.
2. **Sowing Seeds (if starting from seeds):** If you’re starting from seeds, sprinkle them evenly over the surface of the soil. Cover them with a thin layer of potting mix (about ¼ inch). Gently water the soil using a spray bottle to avoid disturbing the seeds.
3. **Transplanting Seedlings (if using seedlings):** If you’re using seedlings, gently remove them from their containers. Loosen the roots slightly and plant them in the bottle, spacing them appropriately (usually about 6-8 inches apart). Make sure the top of the root ball is level with the soil surface.
4. **Water Thoroughly:** After planting, water the soil thoroughly until water drains out of the drainage holes. This helps settle the soil and ensures the roots are well-hydrated.

Caring for Your Kale
Now that your kale is planted, it’s time to provide it with the care it needs to thrive.
1. **Sunlight:** Kale needs at least 6 hours of sunlight per day. Place your bottles in a sunny location, such as a balcony, patio, or windowsill. If you don’t have enough natural light, you can supplement with grow lights.
2. **Watering:** Water your kale regularly, especially during hot and dry weather. The soil should be consistently moist but not waterlogged. Check the soil moisture by sticking your finger into the soil. If the top inch feels dry, it’s time to water. I usually water every 2-3 days, but this can vary depending on the weather.
3. **Fertilizing:** Kale is a heavy feeder, so it benefits from regular fertilization. Use a balanced liquid fertilizer diluted to half strength. Fertilize every 2-3 weeks during the growing season. I like to use organic fertilizers like fish emulsion or compost tea.
4. **Pest Control:** Keep an eye out for pests such as aphids, cabbage worms, and slugs. You can control these pests by handpicking them off the plants, using insecticidal soap, or introducing beneficial insects like ladybugs. I’ve found that a strong blast of water from the hose can also dislodge aphids.
5. **Pruning:** Prune your kale regularly to encourage bushier growth. Remove any yellowing or damaged leaves. You can also harvest the outer leaves as needed, leaving the inner leaves to continue growing.
Vertical Gardening with Bottles (Optional)
If you’re really short on space, consider creating a vertical garden with your bottles. Here’s how:
1. **Hanging Bottles:** For the horizontal planting method, you can drill two holes near the top of the bottle on either side. Thread twine or rope through the holes and hang the bottle from a fence, railing, or hook. Make sure the bottles are securely attached and can support the weight of the soil and plants.
2. **Inverted Bottle Method (Self-Watering):** As mentioned earlier, you can cut the bottle in half, invert the top half, and place it inside the bottom half. The top half holds the soil and plant, while the bottom half acts as a water reservoir. The soil wicks up water from the reservoir, providing a consistent supply of moisture. You’ll need to drill holes in the top half for drainage and in the bottom half for hanging.
3. **Stacked Bottles:** Cut off the top of several bottles and stack them on top of each other, creating a tiered garden. You can secure the bottles together with glue or zip ties. This method is great for maximizing space and creating a visually appealing display.
Harvesting Your Kale
The best part of growing your own kale is, of course, harvesting it!
1. **When to Harvest:** You can start harvesting kale leaves when they are about 4-6 inches long. The leaves will be more tender and flavorful when they are young.
2. **How to Harvest:** Use scissors or a knife to cut the outer leaves near the base of the plant. Leave the inner leaves to continue growing. This allows you to harvest kale continuously throughout the growing season.
3. **Enjoy Your Harvest:** Wash the kale leaves thoroughly and enjoy them in salads, smoothies, soups, or stir-fries. Kale is a nutritional powerhouse, packed with vitamins, minerals, and antioxidants.
Troubleshooting
Even with the best care, you might encounter some problems along the way. Here are a few common issues and how to address them:
* **Yellowing Leaves:** This could be a sign of overwatering, underwatering, or nutrient deficiency. Check the soil moisture and adjust your watering schedule accordingly. Fertilize regularly with a balanced fertilizer.
* **Pest Infestation:** As mentioned earlier, keep an eye out for pests and take action promptly. Insecticidal soap, handpicking, and beneficial insects are all effective control methods.
* **Slow Growth:** This could be due to insufficient sunlight, poor soil, or lack of nutrients. Make sure your kale is getting enough sunlight and fertilize regularly. Consider repotting the kale in fresh potting mix.
* **Root Rot:** This is caused by overwatering and poor drainage. Make sure your bottles have adequate drainage holes and avoid overwatering.

Frequently Asked Questions (FAQ)
What type of bottles are best for growing kale?
The best bottles for growing kale are sturdy plastic bottles, such as those used for water, soda, or juice. Look for bottles that are relatively thick and durable to withstand the weight of the soil and plants. Avoid using bottles that have contained harmful chemicals or pesticides, and always clean the bottles thoroughly before planting. Clear or translucent bottles are preferable, as they allow sunlight to reach the soil and roots. However, you can also use opaque bottles, but be mindful of potential overheating in direct sunlight. The size of the bottle will depend on the variety of kale you’re growing and how large you want the plants to get. Larger bottles (2-3 liters) are generally better for mature kale plants, while smaller bottles (1-liter) can be used for starting seedlings or growing smaller varieties.
How often should I water my kale plants in bottles?
The frequency of watering will depend on several factors, including the size of the bottle, the type of soil, the weather conditions, and the size of the kale plants. As a general rule, you should water your kale plants when the top inch of soil feels dry to the touch. During hot, dry weather, you may need to water them daily, while during cooler, wetter weather, you may only need to water them every few days. Be careful not to overwater, as this can lead to root rot. Ensure that the bottles have adequate drainage holes to allow excess water to escape. A good way to check if your kale plants need watering is to lift the bottle. If it feels light, it’s likely time to water.
What type of soil should I use for growing kale in bottles?
The best type of soil for growing kale in bottles is a well-draining potting mix that is rich in organic matter. Avoid using garden soil, as it can be too heavy and compact, which can hinder root growth and drainage. A good potting mix will contain a blend of peat moss, perlite, and vermiculite, which will provide good aeration and drainage. You can also amend the potting mix with compost or other organic matter to improve its fertility. Kale prefers a slightly acidic to neutral soil pH (6.0-7.0). You can test the pH of your soil using a soil testing kit and adjust it accordingly if necessary.
How much sunlight do kale plants need when grown in bottles?
Kale plants need at least 6 hours of direct sunlight per day to thrive. When growing kale in bottles, place them in a location that receives plenty of sunlight, such as a sunny windowsill, balcony, or patio. If you don’t have a location that receives enough sunlight, you can supplement with artificial grow lights. Rotate the bottles regularly to ensure that all sides of the plants receive equal sunlight. Be mindful of potential overheating in direct sunlight, especially if you’re using dark-colored bottles. If the bottles get too hot, move them to a shadier location or provide some shade during the hottest part of the day.
How do I fertilize kale plants growing in bottles?
Kale plants are heavy feeders and require regular fertilization to produce healthy growth. You can fertilize your kale plants with a balanced liquid fertilizer, such as a 10-10-10 or 20-20-20 formula, diluted to half strength. Apply the fertilizer every 2-3 weeks during the growing season. You can also use organic fertilizers, such as compost tea or fish emulsion. Avoid over-fertilizing, as this can lead to excessive leaf growth and reduced flavor. A good way to tell if your kale plants need fertilizer is to look at the color of the leaves. If the leaves are pale green or yellow, it’s likely that they need more nutrients.
How do I prevent pests and diseases when growing kale in bottles?
Growing kale in bottles can help to minimize pest and disease problems, but it’s still important to take precautions. Inspect your plants regularly for signs of pests or diseases, such as aphids, cabbage worms, or powdery mildew. If you find any pests, you can remove them by hand or spray the plants with insecticidal soap or neem oil. To prevent diseases, ensure that the plants have good air circulation and avoid overwatering. You can also spray the plants with a fungicide if necessary. Choose disease-resistant varieties of kale to further reduce the risk of problems.
Can I grow kale in bottles indoors?
Yes, you can grow kale in bottles indoors, but you’ll need to provide adequate light and ventilation. Place the bottles near a sunny window that receives at least 6 hours of direct sunlight per day. If you don’t have a sunny window, you can supplement with artificial grow lights. Ensure that the plants have good air circulation to prevent diseases. You may also need to water the plants more frequently indoors, as the air tends to be drier.
How long does it take for kale to grow in bottles?
The time it takes for kale to grow in bottles will depend on the variety of kale, the growing conditions, and the size of the plants you’re starting with. Generally, you can expect to harvest your first kale leaves about 6-8 weeks after planting. You can continue to harvest leaves as needed, allowing the plants to continue growing.
Can I reuse the soil in the bottles for growing kale again?
While you can technically reuse the soil, it’s generally recommended to replace it with fresh potting mix for each new planting. Over time, the soil can become depleted of nutrients and may harbor pests or diseases. If you do reuse the soil, be sure to amend it with compost or other organic matter to replenish the nutrients. You can also sterilize the soil by baking it in the oven at 180°F (82°C) for 30 minutes to kill any pests or diseases.
What are some creative ways to display my kale bottle garden?
There are many creative ways to display your kale bottle garden. You can hang the bottles from a fence, wall, or balcony railing using rope or wire. You can also create a vertical garden by stacking the bottles on shelves or pallets. Another option is to arrange the bottles in a decorative planter or container. Get creative and experiment with different arrangements to find a display that suits your style and space. Consider painting the bottles or adding decorative elements to enhance the visual appeal of your bottle garden.
