Ideas for Top 20 Vegetables to Grow Indoors: Indoor gardening is simply growing plants indoors. An example might be a residential home, a business location like an office building, a restaurant, or another enclosed space. An indoor garden is a way of overcoming a lack of natural space by creating a garden environment inside your home. If you live in an apartment or house with no garden space, it is a great alternative. Gardeners can also still enjoy fresh produce during the cold winter months. Indoor gardens are a low-maintenance alternative to outdoor gardens. Even if you live in the city and do not have much space for a garden or a green thumb and would like to start small, you can grow your vegetables, herbs, and more. Vegetables can be grown indoors without a lot of maintenance and are straightforward. Growing your vegetables is fun, and you can do it indoors and enjoy fresh vegetables all year round, regardless of the season. It is especially beneficial to those with limited space.
A guide to top 20 vegetables to grow indoors, tips, ideas, secrets, and techniques
Essentials for vegetable growing indoors
Soil: Peat moss, vermiculite, and perlite are typical ingredients in a good indoor potting mix. These soilless mixes are indeed very good at absorbing moisture and resisting compaction, but they tend to dry out very fast. You must also provide a consistent supply of fertilizer since they contain no nutrients.
Temperature: Commonly, plants experience a temperature differential between day and night of at least 10 degrees Fahrenheit. Therefore, having a similar temperature differential in your home will benefit the plants. Most plants also expect a resting period. For example, some flowering plants need a resting period before they will flower.When the intensity and duration of natural light are lowest during late fall and early winter, cut back on water and fertilizer to simulate this resting period. Spring can be declared after the day length increases and the fertilizer and water are stepped up. As a result, your plants will respond with new growth.
Humidity: Although they can survive at 30 to 40 percent relative humidity, most plants thrive at 50 percent relative humidity or higher. When the air is much drier than that, their roots cannot absorb enough water to keep up with the water they lose through their leaves. During the winter, indoor air often has a low humidity level of 10 to 20 percent. You can mist your plants for an hour or so to keep them healthy. Using a cool vapor humidifier would be a better solution (which would be beneficial to you). Plants can also be clustered together to moisten each other’s air as they release moisture into the air. Consider placing your plants in a gravel-filled tray containing about 1/4 inch of water. Water evaporates, humidifying the air around your plants. Make sure the pots do not sit directly in water.
Water: It is more common for houseplants to die from overwatering than from any other cause. The best advice is to resist the temptation to water regularly. When the weather has been sunny and warm, you should water your plants frequently, and if the weather has been excellent and cloudy, you may not need to water your plants at all. You should check the soil of at least a few indicators plants every week and water only if the soil feels dry to a depth of 12 to 1 inch. Drench the root ball until you see some water seeping out of the bottom of the pot when you water. Then, the root ball is moistened thoroughly. Once a month, small pots will benefit from soaking in water for about an hour. When possible, water your plants with room-temperature water to avoid shocking the roots. Using softened water is never a good idea. Plants are adversely affected by salts in softened water. Instead, consider installing a demineralizing attachment to remove impurities, such as lime and chlorine, if your water is hard.
Nutrients: Fertilizer is usually not a big deal for indoor plants. You don’t need to use too much. Be sure to follow the instructions on the package, and err on the weak side. After fertilizing your plants, make sure they are well hydrated. An average 10-10-10 formula is usually sufficient for indoor plants. An organic amendment, such as seaweed or fish emulsion, or a biostimulant, can provide trace nutrients lacking in inorganic plant fertilizers. Compost or worm castings are another way to add organic nutrients. It is essential to be aware that some plants are sensitive to pH levels and that a proper fertilizer can either exaggerate or correct this sensitivity. Occasionally drenching the soil with clean water and then watering again will prevent the build-up of fertilizer salts. Salts in the soil are flushed away.
Vegetables to grow indoors
Carrots: Vegetables like carrots accommodate each other. They are not only excellent for growing indoors but also in containers. If your outdoor conditions are unfavorable, then you can also grow them in heavy soil. You can grow smaller carrot varieties indoors because they need less space and mature more quickly. Use a long container to grow carrots indoors. Cover the seeds lightly with damp peat moss to prevent them from drying out. As long as your soil is moist, your seeds should germinate within two weeks, though the number of days to maturity depends on your growing variety.
Papers: Plants that produce peppers are tropical perennials. The plants wither at even the slightest hint of frost, but indoors they can thrive. Plant some sweet or hot peppers from seed in the late summer if you have a garden and bring them inside. Although you won’t get a large harvest, they will produce. Make sure your peppers receive at least 10 hours of light each day in a container at least eight inches tall.

Furthermore, make sure the container dries out between watering to avoid drowning the plant. Finally, you’ll likely have to help peppers pollinate, although they’re self-pollinating. Alternatively, you can use a cotton swab to dust each flower with pollen by jiggling the plants to shake the pollen from one flower to another.
Horseradish: Horseradish is a cool-season crop whose roots are used as a condiment. Despite being perennial, it is best to grow it annually since its roots become tough and fibrous the second year. A well-drained, moist, rich soil is ideal for growing horseradish in partial shade.
Radishes: It’s already known that you can grow radish microgreens indoors, but you can also grow full-sized radishes. The roots of these vegetables are similar to carrots, and they prefer a more relaxed environment and a deep pot.
Potatoes: It may surprise you, but potatoes (both sweet and regular) can be grown in soil made from scraps. It would help if you started by cutting up a sprouted potato into chunks, placing them sprout-side-up on four inches of soil. In about two months, you will have potatoes. Then, add another four inches of soil on top. It is essential to have a large enough pot because these can get quite large, and you may need to continue adding soil to the pot as they grow to make sure the potatoes are always covered in soil.
Onions: It doesn’t matter whether you add them as a topping to pizza, make a tasty soup, or batter and fry them. You can grow at home year-round from seeds or scraps of other onions, provided that the planter is large enough to allow a bulb to spread out and grow deep in the soil. Upon reaching six inches in height, the stalks are ready for harvesting and enjoying.
Beets: Beets are high in vitamins and minerals, low in calories, and linked to lowering blood pressure. Growing them indoors is surprisingly easy as well. After soaking the beet seeds overnight, plant them in a perforated flat about 2-3 inches deep so they have room to grow. Dwight Schrute would be proud of the purple beets that will soon grow in the soil.
Scallions: A scallion is a vegetable in the onion family that can be eaten raw or cooked. It is often mistaken for herbs but is a vegetable in the onion family. Cook them, sauté them, sprinkle them over baked potatoes, or stir-fry them. They add a little flavor and crunch to any dish. If you want to grow scallions indoors, you should start with scraps from a bunch and plant the white stems in soil or water. Then, please put them in a spot with plenty of sunlight (preferably six hours a day).
Dwarf Beans: They are smaller string beans, which do better indoors since they’re not grown on vines. In addition to being packed with nutrients and fiber, they’re delicious, as well. The bestselling point of these beans is that they are ready to eat after just 45 to 65 days, as they can be harvested before reaching full maturity, so newbie gardeners will not have to be patient.
Peas: Choosing the right kind of pea is the key to successfully growing them indoors. By using a window box and trellis to let the vines grow upward, you can grow dwarf peas or snap peas. When the pears are ripe, don’t forget to pick them right away. You will not only get to eat them (yum), but the plant will also grow other pods in their place, thus maintaining its production.
Eggplant: The word immediately brings to mind eggplant Parmesan, eggplant vegetable towers, or ratatouille. Growing this hearty purple vegetable indoors is not too difficult in a pot or a hydroponic system. If you plan to grow this vegetable, make sure to know its temperature requirements first, as this plant prefers warmer temperatures even more than the tomato plant.
Zucchini: predicting no complaints from the kids as long as we have zoodles for dinner every night. Zucchini is a versatile veggie perfect for low-carb diets since it can substitute everything from spaghetti to lasagna noodles. The plants are relatively easy to grow indoors too, and each one produces an orange flower.
Spring Onions: Perhaps you’ve seen some homegrown spring onions on social media during the pandemic era. Plants can be revived from scraps and are entirely free to grow. First, remove the roots from the bulbs and place them in a jar of water, keeping the roots attached. Make sure you change the water regularly to ensure your spring onions remain healthy. Then, trim them when they are ready to eat and keep them growing.
Cucumbers: Cucumbers are another vegetable that can be grown indoors. Cucumber seeds created explicitly for indoor growth are available for sale in the market. Compared to cucumber seeds’ garden varieties, they may be more expensive, but you’ll achieve better results. Pots for cucumbers should be of significant size. It is because the cucumber needs room to grow during its development process. You’ll also need to create a climbing structure to support the vines. Cucumbers also require a lot of direct sunlight and temperatures between 73 and 79°F when it comes to environmental requirements. Make sure the temperature is lower during nighttime to ensure the best results.

Chives: An herb that’s delicious to have in your kitchen, chives are used in virtually all homemade dishes. It’s easy to grow chives indoors, but if you want a steady supply, they require a few things. To begin with, you should use clay pots filled with potting soil that drains well. If you cannot place the pot in direct sunlight, consider investing in a fluorescent lamp. Second, the plant needs constant sunlight during the day. Finally, humidity is also a favorite of chives. Place the chives pot between the other pots or use a humidifier to increase the humidity in the air if you want to maintain a constant air moisture level.
Turnips: Your indoor vegetable garden should also include turnips as one of the delicious vegetables. They are available in many varieties and can be used in many delicious dishes. A large pot, about 8 inches deep, is required to grow turnips indoors. Additionally, you should choose organic soil that is slightly alkaline. If you want to obtain suitable soil, you should mix regular potting soil with compost. Place the pot in direct sunlight after you have planted the seeds, and water the soil regularly. Then, about two months after planting your turnips, you can harvest them.
Parsnip: Indoor gardening is a good match for parsnips. However, you can still grow a parsnip from the comfort of your home if you have patience and determination. Consider using large pots and only planting fresh parsnip seeds if you decide to give it a try. Make sure your soil has a high ph. Make sure the pot and the soil are well-drained. Seeds for parsnips need to be planted at a distance because the roots are usually significant. When watering, ensure that the soil is damp but not soaked.

Green beans: If you enjoy green beans, you will be pleased to learn that you can grow them indoors in a pot. Green beans of the bush type need a lot of sunlight for development and must be planted in rich soil. The ideal soil is enriched with compost. To grow plants in containers, you should use narrow, 8-inch-deep containers. Keep the soil at a temperature of 85°F, and ensure that the soil surface is always moist. To provide water to the plants, place a sausage under the container and water at the root level. In about two months after planting, you can harvest the green beans.
Cherry tomatoes: If you have a grow light to help them get enough light, you can grow them indoors in warm weather. Nevertheless, plants will need a lot of good light, which is probably impossible without a grow light. They are also self-pollinating, which eliminates the need for pollinating insects. Shake the branches holding the flowers when you see blooms to help the flowers pollinate. It will allow the pollen to fall between flowers.
Green onions: Growing green onions from seeds is possible, but growing them from the roots of scallions you have already grown is much faster and easier. Put the roots in a glass of water so that they are covered. You can grow a green onion from the top of the glass if you place it in the sun.
How to care for growing vegetables indoors
- The first step is to find a large container for your plant’s roots to grow in, with a drainage hole at the bottom. Repurpose old plastic tubs or storage bins for your container, but any pot with a drainage hole will work. To prevent ruining a table or windowsill, you should place your container on a dish, saucer, or tray to catch any moisture that drains out.
- Use indoor potting soil, specifically formulated to grow plants in indoor conditions, to plant your veggies and seeds in your container. Set your plants up next to a sunny window once you have them ready to go.
- Lack of light will be the biggest challenge to growing vegetables indoors. So, it’s essential to mimic the conditions of the outdoors as much as possible by either using window light or even investing in grow lights. Vegetables require at least 4-6 hours of sunlight per day, whereas fruits need 8-10 hours.
- Plants need less water when it comes time to water them. Rather than being exposed to intense outdoor heat, they will not dry out as frequently, so don’t overwater them. Instead, water evenly without becoming too wet.
- Indoor plants can be hard hit by low humidity, so mist them with water or consider purchasing a cool-mist humidifier each day.
- If you don’t have to grow lights, you should still see some sprouts reasonably quickly. However, you may have to wait a few weeks or even months to harvest the edible part of the plant. As you have the most natural light in the summer, it’s the best time of year for growing. Despite the dreary winter weather, indoor vegetables can grow throughout the year.
