Plants can, besides the traditional way of growing in the garden, also be grown in containers, for example on a terrace or balcony!

How to grow tomatoes

• They require a sunny and sheltered location. Ideal temperature conditions for growing are between 21 and 24 °C. Growing tomatoes in a greenhouse or polytunnel is also a possible option, however we should be aware that at temperatures above 27 degrees Celsius tomatoes do not grow. Higher temperatures even cause them to dry out. Generous watering is also necessary. We avoid watering on the leaves, as mildew could attack the plants. We regularly pinch out side shoots to support fruit growth. For staking tomatoes and tomatoes that grow to higher dimensions, it is essential to place support and tie them up so that the plants do not break.

• Tomatoes are sown at the earliest in mid-February, but better at the beginning of March into substrate for sowing and propagation. After 1 – 2 weeks we must prick out the plants into seed trays - the substrate is the same. After 3 – 4 weeks we transplant the plants into pots of at least 8×8cm in size with horticultural substrate. Low temperature and weaker watering are suitable for growing tomatoes. For plants in pots, a temperature up to 15°C is sufficient. We harden off the plants very early - we ventilate or place them outside during the day. We plant out in polytunnels in April, and in open ground in May after frosts.

• Plants are demanding in organic matter and nutrients, therefore it is necessary to additionally mix manure into the growing substrate. It is suitable to use granulated - we add 300 – 400 g per plant to the substrate.

  Tomatoes grown in beds require soil preparation before planting. On good and humus-rich soils it is not necessary to apply manure or compost. On poor soils we incorporate 2-4 kg per m2 of mature compost or manure into the soil already in autumn.

• We regularly fertilise the plants. Application in the form of liquid fertiliser with Kristalon Start or Fruit and Flower fertilisers is suitable. We fertilise with Kristalon START mainly at the beginning of plant growth, as soon as the plants start to flower, we can start using Kristalon FRUIT and FLOWER. We prepare doses according to the instructions on the product packaging.

• The most common disease in tomatoes is tomato blight (potato blight). It is recognised by characteristic brown spots on leaves, stems and fruits. This disease needs to be tackled preventively. If we expect rainy weather, we treat plants with Acrobat, Alliete, Ridomil, Kuprikol etc.

  Blossom end rot in tomatoes is a disorder in plant nutrition - calcium deficiency. It affects the fruits and they become deformed and a black spot appears on the tip of the fruit. We regularly fertilise the plants. If the disorder appears, we treat the plants with preparations for calcium nutrition, such as InCa.

  Sucking pests such as aphids or spider mites attack tomatoes very often. It is suitable to use Agro NATURA Symfonie 3 in 1 against fungal diseases and sucking pests.

  For tomato blight, DITHANE preparation is suitable. For organic farming, Bioton and Bioan preparations are suitable.

• Bush varieties of tomatoes are harvested approximately 8 weeks from planting. Staking types are harvested from the 10th to 12th week. We always follow the appearance of the harvested fruit. Tomatoes should be red, firm, not overripe.
