Start a windowsill garden by taking cuttings from some of your favorite indoor and outdoor plants and rooting them in water. Use pruners or a sharp knife to cut a 2,5 cm of stem; strip off the bottom leaves and place the cut stem in a small container with water.
Although it doesn't suit every plant, rooting plants in water is the easiest propagation method. Change the water in the containers weekly because bacteria may develop in dirty water and create an unhealthy medium for the plants.
Transplanting to Soil
Most plants thrive only a limited time without soil in which to spread their roots. When you transplant rooted cuttings into potting mix, remember that the roots they form in water are finer and more fragile than the ones they develop in soil. For at least a week after transplanting, keep the potting mix moist to allow new roots a chance to grow. However, cuttings that are rooted in soil should be watered once when they're placed in a pot of soil to begin developing, and not again until the soil is almost dry.
Herbs at hand
Few traditional outdoor plants are as easy to grow indoors as herbs. Raise them from cuttings or seeds. Place the plants in your sunniest window where trees and buildings don't obstruct the sunlight.
Some herbs, such as various mints, tarragon, and thyme, grow well in hanging planters. Mints tend to produce smaller leaves when you grow them indoors, but they are just as flavorful. Tarragon succeeds best if you take stem cuttings instead of digging up the whole plant from the garden and attempting to move it indoors.
Indoor herb care tips:
• Because most herbs are fairly drought resistant, they grow well in pots, but when you combine two or three in the same container, they must be compatible in their moisture requirements.
• In heated homes during winter, mist around the plants frequently to circumvent the dry air, as dryness can lead to brown leaf tips and spider mites (rosemary is particularly susceptible to the latter).
• Fertilize herbs once a month.
• Give plants a quarter-turn weekly to expose all sides to the sun.
Growing vegetables indoors is much more difficult, often this may require additional lighting. Plant dwarf varieties of vegetables in pots, window boxes, or improvised containers. Hanging baskets make suitable homes for tomatoes, beans, cucumbers, lettuce, and radishes.
Fertilize vegetables every two weeks. Water to keep the soil evenly moist, especially when plants begin to flower and produce fruit. Help fruit production by lightly brushing plants with your hand to spread pollen as they bloom.
These vegetables can be grown indoors:
Beans, carrots, cherry tomatoes, cucumbers, lettuce, peas, radishes, peppers, eggplants, green onions and spinach.
