In this modern age of concrete jungles and limited outdoor spaces, cultivating pot vegetables may seem like an unattainable fantasy.
Maybe you’ve dreamt of plucking a fresh, juicy tomato from your indoor container garden in the dead of winter. Perhaps you’ve longed to savor the crisp crunch of homegrown bell peppers; either way growing pot vegetables indoors may be the answer!
I’ve had more plants perish under my care than I’d care to admit. However, growing pot vegetables indoors has been surprisingly easy. The best part- I can wave goodbye to the frustrations of pests or extreme climate conditions that plague traditional outdoor gardening. In this controlled environment, you’ll become the master of your indoor veggie garden, sculpting a haven for your pot vegetables to thrive.
Let’s look at some of the container vegetable garden ideas you can grow indoors, what makes them so easy to care for, and some extra handy tips along the way!
Table of Contents
Leafy Greens
This is one of my favorite container plants; they are fast-growing; you can pluck the leaves as you need them, and having them on hand is a gentle reminder to add more greens to my diet!
Getting Started
- Varieties: Lettuce, spinach, kale, arugula, and mustard greens- choose compact or dwarf varieties to maximize your space.
- Container: Use a container with drainage holes to prevent waterlogging. If you recycle a container, drill the holes before filling it with soil. Fill rich, well-draining potting soil with added organic matter for an extra boost. Store-bought potting mix will do the trick.
Caring for Leafy Greens
- Position: Find a south-facing window or use a grow light to supplement the natural light. Aim for 6-8 hours of partial sun daily.
- Planting: I like to start leafy greens in a seed tray and transplant them, but you can scatter the seeds straight into the soil if you want. Ensure you follow the directions on the seed packet for proper spacing and depth.
- Watering: Keep the soil moist by using a spray bottle before germination. This will ensure the seeds don’t rise out of the pot with heavy watering. Avoid over-watering mature plants, as this can lead to root rot.
- Air circulation: This helps to prevent diseases and pests, so if you can run a small fan near your container garden, it will mimic a gentle breeze and keep the plants aerated.
- Temperature: Most leafy greens need around 60-75F (15-24C), making them a great cool weather crop. Aim for a humidity level of around 40-60% (average house humidity). Use a hygrometer to monitor humidity and adjust as needed.
- Fertilizer: Use a balanced, water-soluble fertilizer formulated for veggies. Follow the directions on the packet for dilution and frequency. Avoid over-fertilizing as it can lead to leaf burn.
The young leaves of the greens I mentioned above can be harvested after around 30 days. If you want to harvest a whole lettuce head, you can expect to harvest it after 60 days. For large, fully matured leaves to harvest, expect around 50 days.
What’s great about growing these indoors is they are not prone to bolting in unpredicted weather conditions. As you harvest the young leaves, the plants will continue to grow. Plant the seeds every two weeks to keep a steady supply of greens in your home.
Sweet Peppers
Homegrown peppers are genuinely unbeatable for container gardens. Sink your teeth into their fresh, crunchy flesh, and you’ll instantly recognize how long store-bought peppers have languished on the shelves.
Getting Started
- Varieties: Miniature Bell Peppers, Sweet Banana Peppers, and Patio Peppers all have a compact growth habit, a shorter maturity time, and are great for containers.
- Container: A 5-gallon (19 liter) pot is suitable for one pepper plant. Ensure it is a sturdy material and has drainage holes to prevent water logging.
Caring for Sweet Peppers
- Position: Choose a sunny and warm place near a south-facing window where it can get 6-8 hours of direct sunlight daily. Use a grow light to provide the required light intensity if your home lacks natural light.
- Planting: Use a well-draining potting mix rich in organic matter that’s slightly acidic with a pH level of around 6.0-6.8. Start from seeds indoors 8-10 weeks before the last frost date, or purchase young seedlings from a nursery to transplant into your container. Transplant seedlings into the container, ensuring the root ball is covered with soil and the plant is at the same depth as in the original container.
- Watering: Avoid overly wet soil and water when the top inch of soil feels dry. They are okay being left to dry out a bit, so don’t panic if you forget to water them once or twice.
- Pruning and Support: As the sweet pepper plant grows, consider providing support such as stakes or a tomato cage to keep the plant upright. Prune off suckers (side shoots) to focus the plant’s energy on fruit production.
- Temperature: Warm temperatures between 70-85°F (21-29°C) are ideal during the day for sweet peppers. They can handle slightly cooler temperatures at night. Maintain a humidity level of around 50-70% for the best results.
- Fertilizer: They love a feed, provide a balanced, water-soluble fertilizer every 2-3 weeks, following the package instructions.
As you harvest your sweet peppers, they will continue their life cycle. Typically, they are grown as an annual, and you can see fruit from 70-90 days after transplanting.
However, with the proper controlled conditions, you may find yourself with a perennial pepper plant that will continue to produce fruit for multiple years!
Green Onions
Green onions are fab to have on hand and one of the easiest vegetables to grow. Their leafy tops can be snipped and used similarly to chives, which I love adding to my potato salads!
Moreover, if you trim them at the base, leaving the shallow roots intact in the soil, they will regrow and provide you with a fresh supply of flavorful greens.
Getting Started
- Varieties: Look for Evergreen, Bunching, or Scallions. These are bred explicitly for green onion production and well-suited for container growing.
- Sets or Seeds: Start with onion sets (small bulbs) or seeds. Sets provide a head start, while seeds offer more variety. Purchase them from a nursery or garden center.
- Container: Use a deep container with good drainage. A 6-inch deep pot or a long planter tray is suitable.
Caring for Green Onions
- Soil: Use well-draining potting soil or a mixture of potting soil and compost. Ensure the soil is loose, free from debris, and fertile for healthy root growth.
- Planting: Plant the onion sets or sow the seeds in the soil, following the recommended spacing mentioned on the packaging. For sets, plant them with the pointed end facing up. For seeds, sprinkle them evenly and lightly cover with soil.
- Watering: Regular watering is required to keep the soil consistently moist. Water the green onions whenever the top inch of the soil feels dry. Avoid overwatering, as it can lead to rotting.
- Position: Place them in a sunny location, preferably near a south-facing window, for 6-8 hours daily. If natural light is insufficient, supplement with grow lights for 12-14 hours daily.
- Temperature: Maintain a comfortable room temperature for optimal growth. Green onions prefer temperatures between 60-75°F (15-24°C). They tolerate moderate humidity levels.
- Maintenance: Remove any yellowing or damaged leaves as they appear. Thin out overcrowded seedlings to provide ample space for growth. This can be done by snipping the excess green onions at the base.
Bush Beans
When we envision growing beans indoors, the image of a sprawling vine engulfing our living room might come to mind.
However, that’s different when it comes to bush beans. Unlike climbing varieties, bush beans grow in a compact, bush-like form, eliminating the need for trellises or training them along the walls.
It’s worth noting that bush beans have a distinct advantage—they mature relatively quickly and should be harvested all at once.
Getting Started
- Varieties: Look for options like ‘Provider,’ ‘Contender,’ or ‘Bush Blue Lake.’ These are bush bean varieties well-suited for container gardening and have a compact growth habit.
- Container: A deep 5-gallon (19-liter) pot or larger is usually suitable for one or two bush bean plants. Ensure there is good drainage for healthy roots.
Caring for Bush Beans
- Soil: Fill the container with well-draining potting soil mixed with compost to provide a fertile growing medium. Once the beans have finished their lifecycle, keep the soil. Beans are nitrogen-fixing plants that enriche the soil they are planted in. You can reuse the soil for a heavy-feeding crop later on.
- Planting: Plant bush bean seeds directly into the container according to the recommended spacing, usually 2-3 inches apart. Plant them at a depth of about 1-2 inches. Lightly water them in after planting.
- Position: Place the container in a location that receives full sun for at least 6-8 hours a day. If natural light is limited, supplement with a grow light to ensure the plants receive adequate light.
- Watering: Keep the soil consistently moist but not waterlogged. Water the plants when the top inch of the soil feels dry. Avoid overwatering, as it can lead to root rot. Ensure proper drainage in the container.
- Temperatures: Bush beans thrive in warm temperatures between 70-85°F (21-29°C). Maintain consistent room temperatures to keep them happy.
- Fertilizer: Apply a balanced, water-soluble fertilizer every few weeks according to the package instructions. Avoid over-fertilization, as it can lead to excessive foliage growth at the expense of bean production.
Bush beans mature and are ready for harvest within 50-60 days after planting. Harvest the beans when young and tender before the seeds inside fully develop.
Tomato
Growing tomatoes isn’t limited to the summer season alone. You can enjoy cultivating those luscious, juicy fruits all year round by bringing the process indoors.
One of the most significant advantages of growing tomatoes indoors is your absolute control over their environment. Indoor gardening reduces the risk of encountering pests or diseases commonly affecting outdoor tomato plants.
Getting Started
- Varieties: Select compact or dwarf tomato varieties specifically bred for indoor growing. Look for varieties like ‘Tiny Tim,’ ‘Cherry Cascade,’ or ‘Window Box Roma.’
- Container: Select a spacious and robust container equipped with drainage holes. Typically, a single tomato plant thrives in a 10-15 gallon (38-57 liter) pot, ensuring sufficient room for its root system to grow and develop. Choosing a container that can adequately accommodate the plant’s root requirements is essential.
Caring for Tomatoes
- Position: Position your tomato plant close to a window facing south or utilize the assistance of grow lights to ensure it receives ample sunlight. For optimal growth, tomatoes require a minimum of 6-8 hours of as much sun as possible daily.
- Soil: Opt for a well-draining potting mix specifically formulated for containers. It should be enriched with organic matter and have good moisture retention. A good blend should have 1 -part perlite, 1 -part compost, and 1 -part coconut coir.
- Planting: Start tomato plants from seeds or seedlings from a nursery. If starting from seeds, begin 6-8 weeks before the desired planting time. If using seedlings, transplant them into the container, burying the stem to the first set of leaves for more robust root development.
- Maintenance: Remove any suckers (side shoots) that emerge in the leaf axils to focus the plant’s energy on fruit production. Regularly inspect the plant for pests, diseases, and signs of stress.
- Pollination: Tomatoes are self-pollinating, but indoor-grown plants may benefit from gently shaking the plant or using a small brush to transfer pollen between flowers.
- Watering: Keep the soil evenly moist, avoiding waterlogging and letting it dry completely. Water deeply when the top inch of soil feels dry to the touch.
- Support structure: As the tomato plant grows, provide support using stakes, cages, or trellises. This helps maintain the plant’s upright position and prevents sprawling.
- Temperature: Tomatoes thrive in warm temperatures between 70-85°F (21-29°C) during the day and slightly cooler temperatures at night. Moderate humidity levels are generally suitable. 10-10-10 npk is a suitable all-rounder for tomatoes and other vegetables.
Zucchini
Regarding plants, zucchini, and summer squashes have a knack for growing impressively large. However, their size can be daunting for container gardening.
If you’re constrained by limited space, a clever solution is to use stakes and grow them vertically. By training the zucchini plants to grow upwards, their vines will reach tall heights while allowing the fruits to hang down, making it much easier to harvest them.
Getting Started
- Varieties: Look for options like ‘Patio Star,’ ‘Astia,’ or ‘Eight Ball.’ These compact or bush zucchini varieties are better suited for indoor growing.
- Container: Use a container of at least 5 gallons (19 liters) to provide enough room for adequate root growth. Ensure it has adequate drainage holes as zucchinis don’t like soggy feet.
Caring for Zucchini
- Soil: Use a well-draining potting mix and add some organic material like straw or compost to create a fertile growing medium. I add in some well-rotted chicken manure to give the seedlings a boost.
- Planting: Plant Zucchini from seeds or purchase young seedlings from a nursery. If starting from seeds, sow them directly into the container according to the recommended spacing.
- Position: Place the container in the sunniest location like near a south-facing window or use grow lights to supplement the light requirement. Aim for at least 6-8 hours of direct sunlight or equivalent artificial light daily.
- Temperature: Zucchini plants love the summer heat. Aim for temperatures between 70-85°F (21-29°C) during the day. Avoid temperature fluctuations as much as possible as this can stress the plants and affect their fruiting.
- Watering: Zucchini plants require regular and consistent watering. Keep the soil evenly moist but avoid overwatering, as it can lead to root rot. Water when the top inch of soil feels dry.
- Pollination: Zucchini plants rely on pollinators or gentle manual pollination to produce fruit indoors. Gently shake the plants or use a small brush to transfer pollen between flowers to ensure proper pollination. The male flowers will appear first, and you can pluck one of these to dust onto the female flowers.
- Maintenance: Trim and remove any excessive foliage or side shoots to encourage air circulation and focus energy on fruit production. Provide support such as stakes or trellises to help the plant stay upright.
Harvest zucchini when they reach around 6-8 inches (15-20 cm). Use a sharp knife to cut the zucchini from the plant. Regular harvesting encourages continuous production.
Zucchini flowers are also edible, so early in the morning, you can collect them when they are open and use them in your dishes. They are great stuffed with rice and roasted!
Sweet Potatoes
Sweet potatoes are an underrated plant. They are often used indoors as an ornamental, but some cultivars can produce the edible, healthy tubers we all know and love on our roast dinners.
They are easy to start off from a store-bought potato. With the right container, you can keep them growing for most of the year.
Getting Started
- Varieties: Vardaman, Beauregard, or Bonita are excellent indoor varieties. They have a compact bush growth habit and are bred specifically for indoor container gardening.
- Prepare the slips: Sweet potato plants are typically grown from slips; young shoots sprout from the sweet potato. Purchase or create your slips by placing a sweet potato in a water container until the shoots emerge.
- Container: Choose a container at least 12 inches (30 cm) deep and wide, with sufficient drainage holes. Sweet potatoes require ample depth for their tuberous growth.
Caring for Sweet Potatoes
- Soil: Mix equal parts of potting soil, compost, and sand to create a loose and fertile growing medium. Ensure the medium is free from debris such as rocks and stones for the best tube growth
- Planting: Plant the slips in the container, burying them about halfway into the soil. Space the slips approximately 12-18 inches (30-45 cm) apart to allow room for tuber development.
- Position: Place the container in a sunny position, such as a south-facing window, where it receives at least 6-8 hours of direct sunlight daily. Maintain a warm indoor temperature of around 75-85°F (24-29°C).
- Watering: Keep the soil evenly moist throughout the growing season. Water deeply whenever the top inch of soil feels dry, but avoid overwatering to prevent rotting.
- Fertilizing: Sweet potatoes benefit from regular feeding with a balanced, water-soluble fertilizer formulated for vegetables. Follow the package instructions for dosage and frequency.
- Trellis support: Provide support such as stakes or a trellis to help them climb and prevent them from sprawling too much. Gently guide the vines and tie them to the support structure as needed.
Sweet potatoes take several months to mature, typically around 90-120 days after planting. Harvest them when the foliage starts to yellow and die back. Carefully dig up the tubers, handling them gently to avoid damage.
