Fertilizing tomatoes 2 weeks after planting (in a greenhouse)

Why do gardeners wonder what to feed greenhouse tomatoes two weeks after planting? Because the main goal is to get a good harvest and excellent-tasting fruit. To achieve this, the plants themselves require proper and balanced nutrition, which is where supplemental feeding comes in.

Tomatoes belong to the nightshade family of plants. They are characterized by their responsiveness to any type of soil fertilizer or foliar feeding. However, it's important to understand that any application or spraying should be done carefully and judiciously. Overfeeding a plant will be just as fruitless as underfeeding it. Did you know?

The best fertilizers for tomatoes:

• Potassium. A lack of potassium can slow tomato growth. It actively plays a role in stem formation. If leaves accumulate too much ammonia nitrogen due to a potassium deficiency, they begin to die.
• Phosphorus. Due to the deficiency, the stems become brittle and wilted, and a purple tint appears on them.
• Nitrogen. Deficiency results in poor fruit formation.

When to apply and how

The first time you should think about feeding tomatoes in a greenhouse is not two weeks after planting, but immediately after planting the young bushes. Add a generous amount of compost or humus to the holes, then sprinkle everything with ash. Compost (humus) is rich in minerals, and ash enriches the soil with macronutrients. With this fertilizer, tomatoes will begin to grow vigorously and set fruit.

Interesting! Some gardeners believe there's no point in fertilizing tomato plants after they've been planted. They insist the first feeding should be done only 14 days after transplanting them to their permanent location. However, experts are convinced that such restraint can lead to injury to the plant.

Green tea feeding

Fourteen days after planting, you can apply the second fertilizer. Use an organic fertilizer called "green tea." It's easy to make yourself. Take herbs: nettle, horsetail, plantain, and any weeds. Add a bucket of liquid mullein and 250 grams of wood ash. Please note the information. How to properly plant tomatoes in a polycarbonate greenhouse.

Advice! For every 50 liters of water, take 5 kilograms of finely chopped green weeds. Add a bucket of mullein and 250 grams of ash. Mix everything and let it sit for a couple of days. Then bring the mixture up to 100 liters and water each bush with two liters of the mixture.

Mineral fertilizers will stimulate foliage growth, while organic fertilizers will enhance flowering. However, if organic fertilizers are unavailable, any complex mineral fertilizers you have on hand can be used.

Mineral fertilizers for top dressing after 14 days (per ten liters of water):

• 25 g of nitrogen;
• 40 g of phosphorus;
• 15 grams of potassium fertilizer;

Advice! Pour a liter of the resulting mixture for each plant.

The next feeding of tomatoes should be done after flowering begins. Dissolve one tablespoon of potassium sulfate, 500 grams of bird droppings, and 500 grams of liquid mullein in ten liters of water. Use one and a half liters of the solution per hole.

Advice! If organic fertilizer is unavailable, you can dissolve a tablespoon of nitrophoska in a bucket of water and fertilize your tomatoes during flowering. Use a liter of solution per plant. Incidentally, this is also an excellent way to prevent rot on tomatoes.

When else to apply fertilizer:

• When ovaries begin to form, dilute 10 grams of boric acid in two liters of wood water. Pour the mixture into 10 liters of water. Let the solution sit for 24 hours, then water each bush with a liter. This will speed up ripening and fruit formation.
• The last root feeding is done when the bushes begin to bear fruit. It improves the final flavor of the red fruits and also promotes their vigorous growth. Two tablespoons of superphosphate and a tablespoon of liquid sodium humate are diluted in ten liters of water.

When there is a lack of nutrients

Tomatoes, through their vibrant appearance and changes in their leaves and stems, provide information about what they may be lacking during the growing season.

How to determine the deficiency:

1. There's a phosphorus deficiency. The stems and lower parts of the leaves are turning purple. The plant needs to be sprayed with a superphosphate solution. If done correctly, the purple color will disappear within 20 hours.
2. There's a calcium deficiency. Leaves are starting to curl inward. Fruit is starting to rot at the top. Foliar feeding with calcium nitrate is needed.
3. Nitrogen deficiency. The bushes have a barely green tint, possibly a yellow tint, and are stunted. Foliar feeding with herbal tea will help, and you can also spray with a weak urea solution.

This is all just general information about How to feed tomatoes In a greenhouse, two weeks after planting. Every gardener will have their own secrets and observations here. For example, different types of tomatoes may require different mineral or organic fertilizers. All of this must also be taken into account.
