How to Care for an Indoor Tomato Plant
- 1). Give your tomato plenty of sun. Tomato babies need plenty of sun (or artificial sun) to grow. Position your tomato pots close to the window that receives the most sun. Your tomatoes should be in the light for about 18 to 20 hours, the remaining hours are sleep hours and should be dark. If you live in a darker, colder climate and are trying to grow your tomatoes indoors during the winter, consider purchasing artificial UV lamps from gardening store or tanning salon.
- 2). Fertilize the soil. Before planting, mix in to your potting soil a bit of peat moss (or peat pellets) or worm castings. No one is going to want chicken manure fertilizer inside of their home. It is also a good idea to add a teaspoon of hydrated lime for calcium addition. You can also use standard garden store plant food or enhanced water mix (such as thrive alive and Maxesa). Nitrogen is often a needed element for growing a healthy tomato. The use of plant foods and fertilizers are important as indoor gardens are void of the natural good bacterias, minerals, and nutrients provided out in the open by mother nature.
- 3). Keep warm. Tomatoes grow best in the warm summer sun, so so you need to keep the plants warm. Try to keep the tomatoes at 75 degrees Fahrenheit. If you have trouble maintaining that temperature, consider creating a sort of greenhouse around the plant. Use either an inverted fish bowl or plastic cone to create enclosure. The consolidation of air and space around the tomato will keep it warmer. Peat moss or mulch on the surface of the soil will also help maintain warmer roots.
- 4). Water frequently, but do not drown. Both plastic and clay potting containers retain water much longer than an expansive outdoor vegetable garden, and as such you do not need to water more than a small amount once every or every other day. Water enough just to keep moist.
