Growing tomatoes in wire baskets is an opportunity to harvest vegetables when you have little gardening space available. Wire baskets provide good drainage for tomatoes and allow for optimal sunlight when placed in a window. When choosing a tomato, it is best to find a dwarf or container variety, as these grow well in small spaces and don't require much training. Tiny Tim, Cherry Gold, Red Robin and Yellow Canary all have small fruit and mature quickly.
Line your wire basket with sphagnum moss to keep water inside the basket and prevent water spillage. Sphagnum moss provides good drainage and prevents flooding in the basket. Alternatively, the University of Florida Extension recommends lining the bottom of the basket with black plastic and punching holes through it.
Fill the basket to the top of the basket, leaving 1 inch of space with potting soil. One part sand to one part vermiculite is a soil composition recommended by the University of Florida.
Plant your tomato transplants into the soil, covering the roots. Water the plant thoroughly before hanging in the window so that the soil is moist but not flooded. The University of Illinois recommends watering tomatoes in baskets daily once hung, especially during sunny periods.
Apply a water-soluble ammonium nitrate fertilizer to the soil and repeat two more times, once at three weeks and again at six weeks. Use a 10-10-10 water soluble fertilizer if ammonium nitrate is not available.
