DIY Grow Mint in a Styrofoam Box: A Fresh Kick for Your Everyday Life!
Hey everyone! Are you also tired of expensive, wilted mint from the supermarket? Today, I’m going to show you how you can easily grow your own lush mint in a Styrofoam box. This is not only super sustainable, but also really easy and saves money! And the best part: you’ll always have fresh mint on hand for tea, cocktails, or cooking. Let’s get started!
What you need:
- A Styrofoam box (preferably with a lid, but not absolutely necessary)
- A knife or scissors
- Drainage material (gravel, expanded clay, clay shards)
- Potting soil (preferably herb soil)
- Mint seedlings or mint seeds
- Watering can
- Optional: Spray bottle
- Optional: Fleece or jute to line the box
Why a Styrofoam box?
Styrofoam boxes are great for growing plants because they are:
- Lightweight: You can move your mint around without any problems.
- Insulating: They protect the roots from extreme temperatures (both heat and cold).
- Inexpensive or even free: They are often leftover from packaging.
- Moisture-retentive: This is especially important for mint, which likes it moist.
Step-by-Step Guide: Growing Mint in a Styrofoam Box
1. Preparing the Styrofoam Box
- Clean: First, you should thoroughly clean the Styrofoam box. Remove all labels and residues. A damp cloth is usually sufficient.
- Drill drainage holes: This is super important so that the water can drain and the roots don’t rot. Take a knife or scissors and poke several holes in the bottom of the box. I recommend at least 5-6 holes, depending on the size of the box. Make sure the holes are not too big, so the soil doesn’t fall out.
- Optional: Lining: If you wish, you can line the box with fleece or jute. This prevents soil from being washed out through the drainage holes and keeps the box cleaner. Cut the fleece or jute to size and place it in the box.
2. Adding Drainage and Soil
- Drainage layer: Fill a layer of drainage material (gravel, expanded clay, or clay shards) on the bottom of the box. This layer should be about 3-5 cm high. The drainage ensures that excess water can run off and the roots do not stand in water.
- Fill with soil: Fill the box with potting soil. It’s best to use herb soil, as it is specially adapted to the needs of herbs. Leave about 2-3 cm of space at the top to the edge of the box. The soil should be loose and airy.
3. Planting the Mint
- Prepare seedlings (if you are using seedlings): If you have mint seedlings, gently loosen the roots. This helps the roots to establish themselves better in the new soil.
- Dig planting holes: Dig small holes in the soil, large enough to accommodate the root balls of the mint seedlings. The distance between the holes should be about 15-20 cm.
- Plant the mint: Place the mint seedlings in the holes and fill the holes with soil. Press the soil down lightly.
- Sow seeds (if you are using seeds): If you are using mint seeds, distribute the seeds evenly on the soil. Cover the seeds lightly with soil.
4. Watering and Care
- Initial watering: Water the mint thoroughly after planting or sowing. The soil should be well moistened.
- Choose a location: Place the Styrofoam box in a bright spot, but not in direct midday sun. Mint prefers partial shade.
- Water regularly: Water the mint regularly, but avoid waterlogging. The soil should always be slightly moist. On hot days, you may need to water daily.
- Fertilize (optional): If you wish, you can fertilize the mint regularly. Use an organic herb fertilizer for this.
- Pruning: Prune the mint regularly to encourage growth. You can simply pick off the leaves or cut the stems with scissors.
- Overwintering: Mint is hardy, but in a Styrofoam box, it could use some protection. Place the box in a sheltered location and cover it with fleece.
Tips and Tricks for Lush Mint
- Mint is an invader: Mint tends to spread aggressively. If you plant it in a garden bed, you should plant it in a pot to prevent it from spreading uncontrollably. You won’t have this problem as much in the Styrofoam box, but you should still make sure it doesn’t grow too densely.
- Harvest regularly: The more you harvest, the more the mint grows. Cut back the stems regularly to encourage growth.
- Propagate mint: You can easily propagate mint from cuttings. Cut off a stem and place it in a glass of water. After a few days, roots will form, and you can plant the cutting in a pot.
- Pests and diseases: Mint is relatively robust, but it can be affected by aphids or powdery mildew. Check the plants regularly and treat them with a suitable agent if necessary.
- Different mint varieties: There are many different types of mint, such as peppermint, spearmint, chocolate mint, or lemon mint. Try out different varieties and find your favorite!
- The right soil: Be sure to use herb soil. Regular potting soil is often too rich in nutrients and can cause the mint to grow too quickly and lose its flavor.
- Sun and shade: Mint likes it bright, but not too sunny. A partially shaded location is ideal. If the leaves turn yellow, the mint is getting too much sun.
- Don’t forget to water: Mint needs regular water. The soil should always be slightly moist. However, avoid waterlogging, as this can lead to root rot.
- Fertilizing: Fertilizing is not absolutely necessary, but it can promote growth. Use an organic herb fertilizer.
- Pruning: Regular pruning is important so that the mint grows bushy and not too long and thin. Simply cut the stems with scissors.
- Overwintering: Mint is hardy, but in a Styrofoam box, it could use some protection. Place the box in a sheltered location and cover it with fleece.
Harvesting and Using Mint
You can harvest the mint as soon as it is large enough. Simply cut the stems with scissors. The mint tastes best when you use it fresh. However, you can also dry or freeze it.
Uses:
Decoration: Mint makes a beautiful decoration for drinks and dishes.
Tea: Fresh mint is perfect for a refreshing tea.
Cocktails: Mint is an important ingredient in many cocktails, such as Mojito or Mint Julep.
Cooking: Mint pairs well with many dishes, such as salads, soups, or meat dishes.
Desserts: Mint is a great ingredient for desserts, like ice cream or chocolate cake.

Frequently Asked Questions (FAQ)
What kind of styrofoam box is best for growing mint?
The ideal styrofoam box for growing mint is one that is clean, sturdy, and has not been used to store harmful chemicals. Food-grade styrofoam boxes are generally safe. Avoid boxes that have contained pesticides or other toxic substances. The size of the box will depend on how much mint you want to grow, but a box that is at least 12 inches deep is recommended to allow for adequate root growth. Make sure to thoroughly clean the box with soap and water before planting.
How do I ensure proper drainage in a styrofoam box?
Proper drainage is crucial for preventing root rot in mint plants. To ensure adequate drainage, drill several holes (at least 4-6) in the bottom of the styrofoam box. The size of the holes should be about 1/2 inch in diameter. You can also add a layer of gravel or pebbles at the bottom of the box before adding the soil. This will help to improve drainage and prevent the soil from becoming waterlogged. Consider placing the box on bricks or a raised platform to further enhance drainage.
What type of soil should I use for growing mint in a styrofoam box?
Mint thrives in well-draining, nutrient-rich soil. A good potting mix is essential. Avoid using garden soil, as it can be too heavy and may not drain well. A mixture of potting soil, compost, and perlite is ideal. The compost will provide essential nutrients, while the perlite will improve drainage and aeration. You can also add a slow-release fertilizer to the soil to provide a steady supply of nutrients to the mint plants. Aim for a slightly acidic to neutral pH level (around 6.0 to 7.0).
How much sunlight does mint need when grown in a styrofoam box?
Mint prefers partial shade to full sun. Ideally, your styrofoam box mint garden should receive at least 4-6 hours of sunlight per day. However, in hotter climates, it’s best to provide some afternoon shade to prevent the leaves from scorching. Monitor your mint plants closely and adjust their location as needed. If the leaves are pale or leggy, it may indicate that they are not getting enough sunlight. If the leaves are scorched or wilted, it may indicate that they are getting too much direct sunlight.
How often should I water mint grown in a styrofoam box?
Mint plants need consistent moisture, but they don’t like to be waterlogged. Water your mint plants when the top inch of soil feels dry to the touch. The frequency of watering will depend on the weather conditions and the type of soil you are using. In hot, dry weather, you may need to water daily. In cooler, wetter weather, you may only need to water every few days. When watering, water deeply until the water drains out of the drainage holes. Avoid overhead watering, as this can promote fungal diseases.
How do I harvest mint from a styrofoam box?
Harvesting mint is easy and can be done regularly throughout the growing season. Simply snip off the stems with scissors or pruning shears. It’s best to harvest mint in the morning, after the dew has dried. You can harvest up to one-third of the plant at a time without harming it. Regular harvesting will encourage the plant to produce more leaves. You can use the fresh mint leaves immediately or dry them for later use.
How do I prevent mint from spreading too much in a styrofoam box?
Mint is known for its aggressive growth habit, but growing it in a styrofoam box helps to contain its spread. However, it’s still important to monitor the plant and prune it regularly to prevent it from becoming too crowded. You can also remove any runners that escape from the box. If the mint becomes too dense, you can divide the plant and replant it in separate containers.
Can I grow different varieties of mint in the same styrofoam box?
While it’s possible to grow different varieties of mint in the same styrofoam box, it’s generally not recommended. Mint varieties can cross-pollinate, which can alter their flavor and characteristics. Additionally, some varieties may be more aggressive than others and outcompete the weaker varieties. If you do decide to grow different varieties together, make sure to provide them with plenty of space and monitor them closely.
How do I overwinter mint grown in a styrofoam box?
Mint is a perennial plant, meaning it will come back year after year. In colder climates, it’s important to protect your mint plants during the winter months. You can overwinter your styrofoam box mint garden by moving it to a sheltered location, such as a garage or shed. Water the plants sparingly during the winter months, only when the soil is dry to the touch. In the spring, move the box back outdoors and resume regular watering and fertilizing. You can also mulch around the base of the plants to provide extra insulation.
