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 solution for you: growing kale in bottles! It’s a fun, eco-friendly, and surprisingly effective way to cultivate this leafy green, even if you only have a balcony or a sunny windowsill. I’ve been doing this for a while now, and I’m excited to share my step-by-step guide with you. Let’s get started!
What You’ll Need
Before we dive into the nitty-gritty, let’s gather our supplies. Here’s a list of everything you’ll need to successfully grow kale in bottles:
* Plastic Bottles: The size depends on how much kale you want to grow. I usually use 2-liter soda bottles or larger water bottles. Make sure they’re clean!
* Kale Seeds: Choose your favorite variety! I personally love ‘Lacinato’ (dinosaur kale) and ‘Red Russian’ for their flavor and visual appeal.
* Potting Soil: A good quality potting mix is crucial for healthy kale growth. Avoid using garden soil, as it can be too dense and may contain pests or diseases.
* Scissors or a Utility Knife: For cutting the bottles. Be careful!
* Drill or Nail: To create drainage holes.
* Watering Can or Spray Bottle: For watering your kale.
* Optional:
* Liquid Fertilizer: To give your kale a boost.
* Gravel or Small Stones: For drainage at the bottom of the bottle.
* Gloves: To keep your hands clean.
* Labels: To identify your kale varieties.
Preparing the Bottles
This is where we transform those empty bottles into mini kale gardens!
1. Clean the Bottles: Thoroughly wash the bottles with soap and water to remove any residue. Rinse them well and let them dry completely. This is important to prevent any contamination that could harm your kale.
2. Cut the Bottles: Decide how you want to cut your bottles. There are a few options:
* Option 1: Horizontal Cut: Cut the bottle horizontally about two-thirds of the way up. This creates a larger planting area. You can invert the top portion into the bottom to create a self-watering system (more on that later!).
* Option 2: Vertical Cut: Cut the bottle vertically down the middle. This creates two separate planters. This is a good option if you want to grow different varieties of kale or if you want to maximize space.
* Option 3: Hanging Planter: Cut a rectangular opening on one side of the bottle, leaving the top and bottom intact. This creates a hanging planter. You’ll need to create holes for hanging (see step 4).
I usually go with the horizontal cut because I like the self-watering option.
3. Smooth the Edges: After cutting, the edges of the plastic can be sharp. Use sandpaper or a lighter (carefully!) to smooth them out. This will prevent you from accidentally cutting yourself.
4. Create Drainage Holes: This is crucial! Kale needs good drainage to prevent root rot. Use a drill or a nail to create several drainage holes in the bottom of the bottle. If you’re making a hanging planter, create holes near the top for hanging as well. I usually make about 5-6 holes, depending on the size of the bottle.
Planting the Kale Seeds
Now for the fun part – planting the seeds!
1. Add Drainage Layer (Optional): If you’re using the horizontal cut method and creating a self-watering system, add a layer of gravel or small stones to the bottom of the bottle. This will help with drainage and prevent the soil from becoming waterlogged.
2. Fill with Potting Soil: Fill the bottle with potting soil, leaving about an inch of space at the top. Gently pat down the soil to remove any air pockets.
3. Sow the Seeds: Sprinkle the kale seeds evenly over the surface of the soil. Don’t overcrowd them! I usually aim for about 3-4 seeds per bottle, depending on the size.
4. Cover the Seeds: Lightly cover the seeds with a thin layer of potting soil. About ¼ inch is perfect.
5. Water Gently: Use a watering can or spray bottle to gently water the soil. Be careful not to wash away the seeds. The soil should be moist but not soggy.
Caring for Your Kale
Now that your kale is planted, it’s time to nurture it and watch it grow!
1. Location, Location, Location: Kale needs at least 6 hours of sunlight per day. Place your bottles in a sunny location, such as a windowsill, balcony, or patio. If you don’t have enough natural light, you can supplement with a grow light.
2. Watering: Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. If you’re using the self-watering system, make sure the bottom reservoir is filled with water.
3. Fertilizing: Kale is a heavy feeder, so it benefits from regular fertilization. Use a liquid fertilizer diluted to half strength every 2-3 weeks. I like to use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium.
4. Thinning: Once the seedlings emerge and have a few true leaves, thin them out to the strongest plant. This will give the remaining plant more room to grow and prevent overcrowding. Don’t be afraid to snip off the weaker seedlings!
5. Pest Control: Keep an eye out for pests such as aphids, cabbage worms, and slugs. If you spot any pests, you can try hand-picking them off or using an organic insecticide. I’ve found that a strong spray of water can often dislodge aphids.
6. Harvesting: You can start harvesting kale leaves when they are about 4-6 inches long. Simply cut off the outer leaves, leaving the inner leaves to continue growing. This will allow you to harvest kale continuously for several weeks. I usually harvest from the bottom up, taking the oldest leaves first.
Tips and Tricks for Success
Here are a few extra tips and tricks I’ve learned along the way to help you maximize your kale-growing success:
* Rotate Your Bottles: If you’re growing kale on a windowsill, rotate the bottles regularly to ensure that all sides of the plant receive equal sunlight. This will prevent the plant from leaning towards the light.
* Use a Self-Watering System: As I mentioned earlier, inverting the top portion of the bottle into the bottom creates a self-watering system. This is a great way to keep the soil consistently moist, especially if you’re prone to forgetting to water. Just make sure the wick (usually a piece of cloth or rope) is touching the water in the bottom reservoir.
* Choose the Right Variety: Some kale varieties are better suited for container gardening than others. ‘Dwarf Blue Curled’ and ‘Red Russian’ are two good options.
* Provide Support: As your kale plants grow taller, they may need some support. You can use stakes or bamboo skewers to prop them up.
* Protect from Frost: Kale is relatively cold-hardy, but it can be damaged by frost. If you live in an area with cold winters, bring your bottles indoors or cover them with a blanket during frosty nights.
* Succession Planting: To ensure a continuous harvest of kale, sow new seeds every few weeks. This is called succession planting.
* Don’t Give Up! Sometimes things don’t go as planned. If your kale doesn’t thrive at first, don’t be discouraged! Experiment with different varieties, watering schedules, and fertilizer levels until you find what works best for you.
Troubleshooting
Even with the best care, you might encounter some problems. 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. If the soil is dry, water more frequently. If the soil is soggy, water less frequently. You may also need to fertilize your kale.

Frequently Asked Questions (FAQ)
What kind of bottles are best for growing kale?
The best bottles for growing kale are typically plastic bottles, such as those used for water, soda, or juice. These are readily available, lightweight, and easy to work with. Look for bottles that are at least 2 liters in size to provide enough space for the kale roots to grow. Clear or translucent bottles are preferable as they allow sunlight to reach the soil. However, it’s crucial to protect the roots from direct sunlight, which can overheat them. You can do this by painting the outside of the bottle (except for a strip to monitor soil moisture) or by placing the bottle in a shaded area during the hottest part of the day. Glass bottles can also be used, but they are heavier and more prone to breakage. Ensure any bottle you use is thoroughly cleaned before planting.
How often should I water my bottle-grown kale?
Watering frequency depends on several factors, including the size of the bottle, the type of soil, the weather conditions, and the stage of kale growth. Generally, you should water your bottle-grown kale when the top inch of soil feels dry to the touch. During hot and dry weather, you may need to water daily, while in cooler or more humid conditions, watering every other day may suffice. Avoid overwatering, as this can lead to root rot. Ensure the bottle has adequate drainage holes to prevent water from accumulating at the bottom. A good way to check if your kale needs watering is to lift the bottle; if it feels light, it’s likely time to water.
What kind of soil should I use for growing kale in bottles?
The ideal soil for growing kale in bottles is a well-draining potting mix that is rich in organic matter. A mix of equal parts compost, peat moss (or coconut coir), and perlite or vermiculite works well. Compost provides essential nutrients, peat moss (or coconut coir) helps retain moisture, and perlite or vermiculite improves drainage. Avoid using garden soil, as it can be too heavy and may contain pests or diseases. You can also amend your potting mix with slow-release fertilizer to provide a steady supply of nutrients to your kale plants.
How much sunlight does bottle-grown kale need?
Kale thrives in full sun, which means it needs at least 6 hours of direct sunlight per day. However, in very hot climates, kale can benefit from some afternoon shade to prevent the leaves from scorching. If you’re growing kale indoors, place the bottles near a sunny window or use grow lights to supplement natural light. Rotate the bottles regularly to ensure that all sides of the plant receive adequate sunlight. Insufficient sunlight can result in leggy growth and reduced yields.
How do I fertilize my bottle-grown kale?
Kale is a heavy feeder, so regular fertilization is essential for healthy growth. You can fertilize your bottle-grown kale with a liquid fertilizer diluted to half strength every 2-3 weeks. Choose a fertilizer that is high in nitrogen, as nitrogen promotes leafy growth. Alternatively, you can use a slow-release fertilizer incorporated into the potting mix at planting time. Organic options include compost tea, fish emulsion, and seaweed extract. Avoid over-fertilizing, as this can burn the roots and damage the plant.
How do I protect my bottle-grown kale from pests and diseases?
To protect your bottle-grown kale from pests and diseases, start by using clean bottles and fresh potting mix. Regularly inspect your plants for signs of pests or diseases, such as aphids, cabbage worms, or powdery mildew. If you spot any problems, take action immediately. For aphids, you can spray the plants with a strong stream of water or use insecticidal soap. Cabbage worms can be handpicked or treated with Bacillus thuringiensis (Bt), a natural insecticide. Powdery mildew can be prevented by ensuring good air circulation and avoiding overhead watering. You can also spray the plants with a fungicide if necessary. Companion planting with herbs like basil or thyme can also help deter pests.
When and how should I harvest my bottle-grown kale?
You can start harvesting kale leaves when they are about 4-6 inches long. Harvest the outer leaves first, leaving the inner leaves to continue growing. This cut-and-come-again method allows you to harvest kale continuously throughout the growing season. To harvest, simply cut the leaves off at the base of the stem with a sharp knife or scissors. Avoid harvesting more than one-third of the plant at a time, as this can stress the plant and reduce yields. Freshly harvested kale is best used immediately, but it can be stored in the refrigerator for up to a week.
Can I grow kale in bottles indoors?
Yes, you can absolutely grow kale in bottles indoors. The key is to provide adequate light, either through a sunny window or with grow lights. Ensure the bottles have good drainage and use a well-draining potting mix. Monitor the soil moisture and water as needed. Indoor kale may require more frequent fertilization than outdoor kale, as it doesn’t have access to natural nutrients in the soil. Also, be mindful of temperature and humidity levels. Kale prefers cooler temperatures and moderate humidity.
How long does it take to grow kale in bottles?
The time it takes to grow kale in bottles depends on several factors, including the variety of kale, the growing conditions, and whether you start from seeds or seedlings. Generally, you can expect to start harvesting kale leaves about 6-8 weeks after planting seeds or 4-6 weeks after transplanting seedlings. Kale is a relatively fast-growing vegetable, so you can enjoy a continuous harvest throughout the growing season.
Can I reuse the bottles for growing kale again?
Yes, you can reuse the bottles for growing kale again. However, it’s essential to thoroughly clean and disinfect the bottles before reusing them to prevent the spread of diseases. Wash the bottles with soap and water, and then rinse them with a solution of 1 part bleach to 9 parts water. Allow the bottles to air dry completely before refilling them with fresh potting mix and planting new kale seeds or seedlings.
