Yes, You Can Grow Tomatoes Indoors Whenever You Want
And that’s what we like! No matter what climate you live in, it’s important to know that you have the ability to grow locally, even in the coldest of climates.
Nothing makes me happier than cutting into a ripe, red, juicy tomato, plastering mozzarella cheese on top, adorning it with a sprig of basil, and shoving it into my mouth. And why should I wait for summer to enjoy home grown luxuries such as tomatoes? Well, I don’t.
So long, pale, hard, tasteless imitations of the real thing. Hello, winter-grown, juicy tomatoes!
How To Grow Tomatoes Indoors
You don’t need a green thumb or a greenhouse to enjoy winter tomatoes, all you need is a window-sill. These ‘window-sill’ tomatoes do well in 6-inch pots filled with good potting soil. Tomatoes grown on the window -sill will be smaller than your average tomato, maybe a quarter to one-half in size, but they come with a great juicy taste…you won’t be disappointed.
Type of Tomato: Cherry or plum tomato varieties perform the best indoors, and they produce a large number of fruit which will ripen quickly.
Starting Seeds: Start your seeds 10-12 weeks before you want to harvest your tomatoes indoors. If you want to begin eating your tomatoes in December for Christmas dinner, make sure to start your seeds in late August.
Buy An Already Grown Plant: If you don’t want to grow your own seeds, you can also go to the local garden store and buy an already grown tomato plant. Just place it on your windowsill and keep it going.
Indeterminate vs. Determinate: If possible, choose indeterminate tomatoes to grow indoors. What does this mean, you ask? Indeterminate plants never set a terminal amount of flower clusters, only lateral ones, and will continue to produce fruit all season long. Determinates, on the other hand, will produce fruit for a couple of weeks and then will fade out. The cherry and plum tomatoes we suggested will be a good option for indeterminate tomatoes.
You’ll want to follow the same seed starting process for indoor tomatoes as you would for the spring, no difference!
Which Windowsill Do You Use?
The windowsill you use, matters. Make sure to place your plant in the sunniest window possible, one that allows a lot of natural light is best. For example, a bay window, picture window, or floor to ceiling window will do best. Also, pick a window with southern exposure, if possible.
Sunlight: Your tomato plant will need a lot of consistent light, around 12-18 hours per day. Turn the plants each day so all branches get their equal turn in the light. When daylight becomes too short, consider getting a grow light to place over your plants.
Heat: Tomatoes obviously do better in warmth, temperatures between 65 degrees and 85 degrees Fahrenheit. Use a space heater, or keep your heat on above 65 in the winter to guarantee health to your darling tomatoes.
Water: You’ll want to water your tomatoes regularly, check the soil daily and keep it evenly moist.
Tap Those Stems!: While your plants outdoors get pollination from bees and other insects, indoors they don’t have a chance. As their last hope, you must do some pollinating. When watering, make sure to tap the stems or use a fan to move the air around in the room. This will help to pollinate blossoms.
Fertilizer: Fertilizing will be important since they won’t be able to dig their roots very deep into the pot and gain nutrients. They will only feed on what you give them, so make sure to feed your tomatoes every two weeks with a balanced fertilizer.
Growing tomatoes indoors does not have to be a chore or something someone else does. With a little patience and lots of love, you’ll be growing fantastic, juicy, ripe, red, beautiful tomatoes even in the depths of winter!
Don’t fret when you hear the words, “Winter is coming”, because now you know how to beat the cold and keep growing through all seasons!
