How to Grow Vegetables Inside in the Winter

Updated: Nov 16

You may anticipate a sad end to the gardening season as the winter weather rolls in. But our relationship to plants and gardening doesn’t have to come to a close with the colder weather. You can easily grow your own indoor garden this winter with just a bit of planning and creativity. Whether you’re looking to brighten up a small space with foliage, enjoy freshly grown herbs, or create an educational opportunity for kids, indoor gardening can provide plenty of joy all winter long. Gardening offers many health benefits and can be a great way to reconnect to nature during the colder months of the year.


Bring your winter garden to life with these steps

Before you get started, it’s good to have a sense of your own goals for your garden. Are you hoping for a harvest you can enjoy eating, or just a pretty garden to tend to? If you have children, what plants offer opportunities for learning? If you love to cook, which herbs are a mainstay in your favourite recipes? Spend a few minutes writing down your vision for your garden, so you know what your goals are. Then it’s time to bring your vision to life.


1. Choose your plants wisely

When gardening indoors, you’ll need to make intentional choices with the crops you plant. Not all plants can handle an indoor environment, and some may require modifications to lighting and climate in order to thrive. Remember that leafy plants generally do well in indoor or shaded areas. Some herbs are also hearty indoor growers that you’ll be able to grow with ease. Typically vegetables need 4-6 hours of sunlight, while other crops (like fruit and certain flowers) won’t thrive unless they have 8-10 hours of light. Get to know the plants you choose, and you’ll improve your chances of success.


These plants typically grow well indoors:

  • Leafy greens like spinach, kale, and lettuce

  • Herbs like basil, peppermint, parsley, fennel, mint, and oregano

  • Vegetables like radishes, beet greens, green onions, scallions, and arugula

2. Read the room

Stand in the room where you’ll be planting your indoor garden and notice the light, humidity, and other factors. You’ll want to choose a place where a plant looks good, but it’s even more important that your indoor garden is planted in the best location to thrive. Beware of easily missed factors like heating vents where hot, dry air blows directly on a plant, unsealed windows where a cold draft comes in, or high-traffic areas where an excited pet or a new guest could bump into your plants. Which way does your window face? The sunlight coming through will affect your garden’s growth potential, and so will the lights in your home. Understanding the light in your space can help you plan ahead, so you’ll know if you should be choosing shade plants or those that love the sun. 


3. Choose the perfect container

It’s great to grow plants from seedlings, so look for ready-to-plant herbs when you’re starting your garden to make life easy. For some plants, you’ll likely need to grow plants from seeds. You can use almost anything for tiny sprouting seedlings: paper cups, egg cartons, or tiny containers. When choosing the right container for the rest of your indoor garden, you’ll want to consider how big your plants will be when fully grown. Although you may be planting seedlings, your plants could get big and replanting indoors is a messy hassle. Choosing the right container also gives your plants room to stretch their roots out and start a lovely journey to maturation. If you’re growing leafy greens, you can make do with small pots or small planters. If you’re attempting a more ambitious crop like indoor tomatoes, you’ll need to consider a bigger box with support for stalks as they grow. Don’t forget about the drainage! If your pot or container doesn’t have a hole in the bottom, consider lining the bottom with pebbles to avoid root rot. 


4. Beware the indoor plant pest

Gnats, mites, tiny flies, and other bugs can feed on composted soil or wood particles in your plant pots. There are easy, natural solutions to most indoor pests; try filling up a spray bottle with a tiny spoonful of dish soap and lots of water, and spray liberally on the top layer of soil. This will keep gnats and other bugs from laying eggs and thriving on your plants. You can always repot or gently clean off a plant if you’re noticing bugs or flies congregating on the base of the plant. Regularly clean up any fallen leaves or plant debris, and make sure you keep cut flowers away from your indoor garden, so gnats and other insects don’t have a chance to migrate to your indoor garden.


5. Get the right tools

You likely already have many of the tools you’ll need to grow an indoor garden, but it’s wise to be prepared. Consider your light sources, potting soil, available containers, and watering methods. If you’re noticing a lack of light in your house or you’re looking to grow more edible plants that require brighter rooms, you may want to invest in some grow lights, like high-output LED lights, fluorescent lights, or indoor sun lamps. Soil is incredibly important, so choose a rich indoor potting mix that feeds your plants and helps them grow. You may want to purchase a spray bottle to refresh tired leaves and feed without overwatering. If you’re looking to get creative, Pinterest is a great resource to explore projects like building your own planters, reusing household objects to plant, and creating a beautiful indoor aesthetic with your new indoor garden.
