How to Get Started with Your Indoor Vegetable Garden
Starting an indoor vegetable garden is a great way to have fresh produce all year round, and it’s easier than you might think. Here’s everything you need to get started:
- Containers: The first thing you’ll need is a container. As long as it has drainage holes, you can use almost anything – terra cotta pots, plastic pots, wooden planters, window boxes, or even fabric pots. Fabric pots are great because they allow the roots to breathe by air pruning them, which means no more rootbound plants.
- Potting mix: High-quality potting soil is a must for container plants. It provides a loose, fluffy medium that retains moisture and drains excess water. Some potting soils may also include compost, mycorrhizae, worm castings, fertiliser, or other supplements that boost biological activity. It’s also easy to make your own potting mix at home. Just make sure not to use topsoil or soil from your garden, as it can suffocate the roots.
- Fertiliser: Indoor-grown vegetables benefit from organic liquid or granular fertilisers throughout the growing season. We recommend using kelp meal as it’s a sustainable and completely natural product that contains over 70 vitamins and minerals. However, kelp meal does not provide enough NPK (nitrogen, potassium, and phosphorus) so an additional fertiliser is needed.
- Light: Light is also important, most vegetables need at least 6 hours of direct sun to thrive, temperature, humidity and water.
- Temperature: When it comes to temperature, vegetables thrive in a consistent room temperature between 18°C and 30°C. To avoid drafts, try to keep your plants away from sources of dry heat such as fireplaces and heating vents.
- Humidity: Humidity is also important to keep in mind, especially during the dry winter months when indoor heating can quickly dehydrate plants and soil. To maintain a healthy humidity level, you can use a room humidifier or place your plants farther away from heat sources and make sure you’re consistently watering your plants.
- Air flow: To ensure good growth, proper air flow is also important to prevent mould and fungal diseases. A simple house fan (like a box fan or oscillating desk fan) on low speed for a few hours each day near your plants should do the trick.
The Pros & Cons of Indoor Gardening
As with everything, it’s important to weigh up the pros and cons before starting your indoor veggie patch adventure. Here are some things to consider:
Pros of indoor gardening:
- Year-round gardening: Indoor gardening allows you to grow vegetables and herbs all year round, regardless of the weather outside.
- Space-saving: Indoor gardening is a great option if you have limited outdoor space.
- Pest and disease control: Indoor gardening gives you more control over pests and diseases that can wreak havoc on outdoor veggies.
- Increased yield: Growing veg indoors often produces higher yields than outdoor gardens due to the ability to control temperature, light, and humidity.
- Convenience & cost-effectiveness: Don’t pay supermarket prices – grow your own produce right from the comfort of your own home.
Cons of indoor gardening:
- Limited plant options: Some plants can’t be grown indoors due to the lack of natural light or other environmental factors.
- Maintenance: Indoor gardens require more maintenance and attention than outdoor gardens due to the need to control temperature, light, and humidity.
- Pest and disease control: While indoor gardening allows for more control over pests and diseases, it can also make it more difficult to detect and diagnose problems.
Can You Grow Vegetables Indoors All Year Round?
The answer is yes! It’s possible to grow vegetables indoors all year round. Indoor gardening allows you to control the temperature, light, and humidity, making it possible to grow a variety of vegetables indoors regardless of the outdoor weather conditions. However, it’s important to note that not all vegetables can be grown indoors and some may require specific equipment, like grow lights, to thrive. Also, keep in mind indoor gardening may require more maintenance and attention when compared to outdoor gardening.
Consider Regrowing Vegetables from Scraps
If the idea of maintaining an indoor vegetable garden sounds like too much work, don’t worry. There’s an even simpler way to grow some types of vegetables in your own home: regrowing them from scraps.
Some vegetables that are great for regrowing include green onions, lettuce, and celery. Here’s how to do it, and before you know it, you’ll have a never-ending supply of these vegetables growing in the comfort of your own home:
- Green onions: Cut off the white part and place it in a glass of water. Keep it in a sunny spot and change the water every few days. In a week or two, you’ll have new green shoots.
- Lettuce: Cut off the bottom of a lettuce head, place it in a dish with a little bit of water and place it in a sunny spot. When roots start to form, transplant them to a pot with soil.
- Celery: Cut off the bottom of the celery, place it in a dish with a little bit of water and place it in a sunny spot. Once roots start to form, transplant it to a pot with soil.
- Garlic: Plant the cloves (pointy end up) about an inch deep in a pot with soil, water it and place it in a sunny spot.
- Cabbage: Cut off the bottom of the cabbage, place it in a dish with a little bit of water and place it in a sunny spot. Once roots start to form, transplant it to a pot with soil.
- Pineapple: Cut off the top of a pineapple, remove any leaves and let it dry out for a day. Then, plant it in a pot with soil, water it and place it in a sunny spot.
- Herbs: Herbs like basil, mint, rosemary, thyme, and parsley can also be regrown from scraps. Simply place the stem cuttings in a glass of water and keep it in a sunny spot. Once roots have formed, transfer the cutting to a pot with soil.
Which Vegetables Can Grow Without Sunlight?
Many vegetables love soaking in the sunlight, like capsicum and tomatoes, while several others can grow without natural light or as little as 3-6 hours of daylight each day. Root vegetables like carrots, potatoes, and beets grow in partial shade, while leafy vegetables like salad greens, spinach, and chard grow well without daylight.
Vegetables like arugula, swiss chard, kale, lettuce, spinach, and root vegetables like carrots, potatoes, radish, beet, cabbage, cauliflower, and many more can grow without sunlight.
What Vegetables Grow The Fastest?
Don’t want to wait a long time for your veggies to grow? While growing veggies doesn’t happen overnight, there are some that grow faster than overs. The fastest-growing vegetables indoors include radishes, green onions, lettuce, baby carrots, spinach, peas, bush beans, kale, turnips, pumpkin, cucumber, leafy greens, and much more.
