The benefits of soda for vegetables

Affordable and cheap bait in the form of a soda solution brings significant benefits when growing vegetables in a summer cottage. Among the main positive qualities of the products are:

  • antiviral and antibacterial action, which allows you to fight pests and infectious diseases of plants on time,
  • properties that increase the resistance of plant crops that resist damage to tomato and cucumber leaves, as a result of which they prevent premature wilting and decay.

Using soda mixtures when growing tomatoes in a summer cottage, you can achieve effective positive results, including:

  • to increase the quantitative characteristics of seedling germination, the quality of tomato ovaries, the productivity of a vegetable crop,
  • improve the external characteristics of vegetables and leaf parts of plants, their taste,
  • reduce the threshold of plant incidence of infectious bacterial and fungal diseases,
  • increase in duration the fruiting period of the plant, scare away harmful insects from tomato bushes.

Spraying tomatoes with solutions with soda allows you to create an environment that repels pests and at the same time does not harm directly the vegetable crop and the future tomato crop. The use of soda solutions deoxidizes the soil layer, lowering acidity.

The use of solutions at different stages of plant development

When growing vegetables at a summer cottage, feeding tomatoes with baking soda is necessary at different stages of growth and development of a vegetable crop.

Seed preparation

It is real to ensure a good crop in the garden only when high-quality seed is planted. You can prepare tomato seeds for planting by soaking in a solution. To do this, they need to be processed during the day in an aqueous solution with 1% content of baking soda in it.

When seeds are soaked in bicarbonate, the period of their stay in it must not be exceeded so as not to lower the quality characteristics of the seed.

After transplanting seedlings

Immediately after transplanting seedlings into the soil, it is recommended to spray the bushes and water them under the root. This will provide reliable protection of the vegetable crop against the appearance of pests, fungus and bacteria and preserve the future tomato crop. To feed and pour bushes with baking soda, a solution with a concentration of 5% is prepared, sprayed and watered with it no more than 1 time per week.

At the stage of intensive development

To increase the intensity of development of vegetable culture, soda solutions are used as fertilizer. Spraying and watering tomatoes gives them healthy, full-fledged growth and increases yield indicators. To this end, they make a 1% soda solution, which is used to water ridges with tomato bushes in the evening no more than once a week, while observing how the plants react to fertilizer. Oversaturation of soil and burns on foliage and stems - a sign to increase the interval between sprayings.

Soda solution increases plant productivity

Watering the beds with tomatoes at the stage of intensive development in the hot season is not used to avoid burns to the plant.

When the primary signs of the presence of insects or fungal diseases appear, tomato bushes are sprayed during feeding, without waiting for the next watering time, proceeding to the procedure immediately.

After the ovary

To make vegetables juicy and tasty will help root watering with a 3.5% soda solution and foliar irrigation by spraying the leaves with a 0.5% composition.

Pest and Disease Control

In addition to the positive effect when growing tomatoes at different stages of plant development, the soda composition is beneficial, preserving the health of tomato bushes, protecting them from attack by pests and preventing the spread of fungal and bacterial diseases.

Powdery mildew

Powdery mildew soda has established itself as an antibacterial agent. For spraying, prepare the mixture in predetermined proportions:

  • baking soda - 50 g,
  • chopped laundry soap - 40 g,
  • water - 10 l.

All components are mixed until they are completely dissolved. Tomatoes are sprayed with a frequency of more than once every 7-10 days.

Aphid, spider mite

To combat aphids and spider mites, 75 g of soda powder is diluted with a 10-liter amount of water. The prepared solution is sprayed on the leaves and stems of the plant with a frequency of once a week.


Against late blight, tomatoes are sprayed with a soda mixture mixed with vegetable oil and laundry soap in a proportion of 2 tbsp. l soda powder for 1 tbsp. l oil and a glass of soap. All ingredients are diluted in a liter of water. Processing is carried out in dry weather in the morning or in the evening, the interval between approaches is 7 days.

Fighting Yellow Foliage

Yellowing leaves in tomatoes is the primary sign of foliage withering and their subsequent decay.

Timely processing of tomato bushes with a soda composition will extend the fruiting period of the vegetable crop. The soda mixture with a low concentration of tomatoes is treated three times in one garden season:

  • twice in the middle of the summer period - at the beginning and at the end of July,
  • one-time closer to mid-August.

For a weakly concentrated composition used in root watering of tomato bushes, 1 tbsp is sufficient. l powder in a 10 liter bucket of water.

Additionally, with a soda mixture, foliage can be sprayed prophylactically against pests. Such treatment will allow the plant to retain strength for a longer period of fruiting.
