The popular tomatoes are not only a pleasure for the classical gardener. They also thrive wonderfully in the pot on a sunny balcony or terrace and do less work than many suspect. With our five tips, your balcony harvest will be a success!
The right tomato for the pot
Do not be afraid to choose a variety: Cultivation in pots is not only possible with small-sized balcony varieties such as 'Miniboy', which are just half a meter high. Even larger bush and stem tomatoes produce delicious fruit in pots containing high-quality vegetable soil - the latter, however, must be well supported, ideally with so-called tomato pillars made of wire mesh. Spiral sticks are not suitable for pot tomatoes, as they do not find enough hold in the potting soil. One of the most important prerequisites for successful tomato cultivation are strong young plants. Too weak or spoiled specimens bring less yield and are more susceptible to disease. So rather sow a few more tomato seeds and use only the best young plants for further cultivation.
Although specialty shops offer special balcony tomatoes, each variety is basically suitable for the pot, provided the plants are well supported
Planters with good drainage
When planting in May or June, do not choose large vessels: pots that hold seven to twelve liters of soil are sufficient. Too much soil can lead to root problems (rot), too small pots, the moisture can control bad and it must be poured more often on hot days. The pit hole should be so deep that the stem bottom is five to ten centimeters high covered with soil. As a result, the plants on the lower stem section form additional roots and can absorb more water and nutrients. But attention: For grafted tomatoes, the pot bale should be barely visible. Make sure that excess water can drain well through openings in the bottom of the pot, because in case of waterlogging the roots rot.
Seven and twelve liters are a good size for the planter
The ideal location for pot tomatoes
Pot-tomatoes love warm places near the house, but no full sun. On undamaged south-facing balconies, overheating of the roots can occur, which often leads to withering of the plants, in spite of damp soil. Some shade through a tree or umbrella at lunchtime is helpful.
A roof against the cabbage blight
Although tomatoes are quite easy to grow plants, they still have a serious opponent: the cabbage blight. It is caused by a fungal pathogen called Phytophthora infestans. And can lead to high yield losses. The leaf infection is favored by moisture. Fortunately, there are several ways to reduce the likelihood of infestation: put your pot tomatoes under a canopy or in a special tomato house so that they do not get direct rain, and when pouring, make sure that the leaves are not moistened. The near-ground leaves should be removed as a precaution if your tomatoes have reached a certain size.
Make sure that you do not wet leaves with water during casting - moisture promotes the late blight
Sea salt provides more aroma
Although tomatoes grow strongly, they only get a dose of tomato fertilizer per week according to the instructions in the package. Long-term fertilizers prove to be unfavorable in pot-tomatoes, as the nutrient delivery is dependent on heat and water and is therefore irregular. An even water supply is also important, otherwise the fruits will burst.
On the balcony with about five hours of sunshine, the varietal aromas can develop best. Through a potash and magnesium fertilizer, the taste can be additionally increased. Moderate watering increases the dry matter content and reduces the water content. Scientists from the University of Pisa (Italy) found out: Cherry tomatoes, whose irrigation water is mixed with 12 percent seawater, are smaller, but contain more flavorings and valuable antioxidants. The same effect can be achieved by adding one gram of sea salt per liter to the irrigation water during fertilization. However, carefully observe the reaction of your tomato plants and, if in doubt, suspend salting because the soil must not be over-salted, otherwise important nutrients such as calcium can no longer be absorbed.
Long-term fertilizers such as fertilizer sticks or pellets are not ideal - prefer liquid fertilizers
