Of course, careful planning is required while purchasing the container, selecting the tomato variety and taking care of the tomato plants. Let's discuss in brief the tips of growing tomatoes in pots and containers.
For planting them in pots and containers, it is always advisable to select the dwarf and bushy variety of tomatoes. With such cultivars, the plants are easy to maintain in a manageable size.
If options are available, choose disease-resistant and indeterminate tomato seedlings. Indeterminate variety produces fruit steadily, whereas determinate variety bears maximum fruits at the same time.
You can purchase ready-made soil or prepare it on your own by adding peat moss and farmyard compost. If you are preparing potting mixture, then supplement with plant nutrients. Remember that the plants directly depend on the potting soil for water and nutrients. Garden soils are usually not preferable as they are very heavy for container gardening.
This way, you are allowing further development of roots from the stem to promote a healthy root system. Make sure that you keep the level of soil a few inches below the rim of the pot. While planting, lightly press or firm the top soil around the seed.
A healthy plant requires about five hours of daily light. You can place the potted tomato plants in any area, either balcony or windowsill, where the plants will get maximum sunlight. If possible, select a location which is less windy, as high-velocity wind may result in drying of the soil.
Once the potted tomato plants are placed in a proper location, water them thoroughly. Make sure to water the plants regularly and supplement the soil with organic fertilizers. For water retention and weed control, you can consider mulching with straw or bark mulch. Provide the tomato plants with supports like stakes or cages, when the first fruits appear.
Depending upon the tomato variety and the growing conditions, the plant will start bearing fruits within 6 - 8 weeks. Growing tomatoes is easy but adequate care should be taken as they are susceptible to diseases.
Majority of the tomato plant diseases are caused due to soil-borne fungi. Hence, as long as the potting soil is disease-free, there are very less chances of diseases in tomato plants. In case of disease occurrence, you can discard the diseased parts as far as possible and use mild fungicides to prevent further spreading.
