Answer: Fertilization of tomatoes
Hello Francesco and thank you for writing to us through the expert column of our website. Our site tries to always be close to readers and to all plants and gardening enthusiasts.
Adding soil and fertilizer to a flowering tomato is not very useful. Usually the fertilizations of the tomato are carried out in two periods, that is, before the transplant and in cover.
Pre-plant fertilization can be done using mature manure or organic products available in any nursery or graden center such as manure, available in both flour and pellets. Floured manure has a cheaper price than pellets as it is simple fractionated dry manure from horses and cattle. Pelleted instead has a slightly lower cost as, thanks to pelleting, it has a more gradual and homogeneous release on the territory and also causes a lower onset of weeds and weeds. In fact, manure, being produced by animals such as cows and horses that notoriously feed on grass, has among the negative effects of its use the onset of weeds on the soils where it is used.
Mature manure must be given in an amount of 3-4 kg / square meter, while if we use mature compost the quantity is slightly less (3 kg). With the fertilizer it is absolutely not necessary to exaggerate as an excess of nitrogen in the soil can cause serious consequences such as an excess of green parts in plants, leaf curling and the presence of small fruits.
Cover fertilization should be done not during flowering but after the early ripening stages of the tomatoes. The quantities of fertilizer must be more limited than with pre-plant fertilization.

The operation is very simple: just make a small hole in the ground (deeper than wide), put 2/3 seeds for each hole, cover with earth and fertilizer then moisten everything.
Leave a space of about 50-100 cm between one hole and the next, because this space will then serve you to pass, water, remove the weeds and collect. In very hot areas, the space between one plant and another can also shorten to 25-50 cm so that they shade each other.
Despite the tomato plant it can handle high temperatures very well, this is still a good way to prevent burns.
The tomato It is an easy-to-grow annual herbaceous plant appreciated for the abundance of its fleshy and pulpy fruits used in fresh cooking and in the form of preserves for winter use.
In this article we describe you how and when to sow and what preliminary operations are necessary such as:
- choose the seeds of the tomato varieties that you intend to grow, possibly eliminating the sick or moldy ones
- polystyrene boxes, chests, pots or planters can be used for sowing or sowing bed
- make sure that the seedbeds are placed in environments where the optimum temperature for the germination of the seeds is constant and not lower than 15 ° C.
Tillage for the cultivation of tomatoes
The tomato is a vegetable plant that develops quite well in any type of well-worked soil, rich in organic substance, well drained and above all exposed in full sun for many hours a day.
The soil destined for the cultivation of tomatoes must in fact be worked thoroughly at a depth of about 30 - 50 centimeters depending on the type of soil and freed from all weeds which in order to develop impoverish the nutritional elements present in it.
If the sowing soil is clayey, too hard and compact, it must be amended to make it soft and rich in organic substance, an operation that must be done in the summer period prior to sowing.
Fertilization of the sowing soil
The soil intended for tomato cultivation must be suitably fertilized at different times to obtain well-developed plants and abundant fruit production.
Generally it must be enriched with essential nutrients such as phosphorus (P), potassium (K) and nitrogen (N).
A first fertilization is carried out with the green manuring of the plants of the previous crops, a second in autumn, burying the mature manure at a depth of 25 centimeters and then before sowing and immediately after transplanting.
Before sowing and immediately after tilling the soil, fertilizer rich in potassium and phosphorus is administered. After sowing and until transplanting the one rich in nitrogen according to the methods and doses indicated on the packages.
Sowing of tomato in seedbeds
Sowing in a protected seedbed is done at the temperature suitable for seed germination. Generally it is carried out by placing only one seed in a container for sowing in the autumn-spring period.
For the cultivation of tomatoes in greenhouses the best period of sowing will be the winter season, for the early crops the summer one for the postponed ones.
Sowing the tomato in the open ground
Sowing in the ground is carried out in spring or by broadcasting or by distributing the seeds directly in already well-worked furrows about one and a half meters away from each other.
The best time for sowing in the open field varies according to climatic zones:
- the March it is the ideal one for the areas of southern Italy,
- for the northern ones it will be the April.
After germination, when the seedlings are about 15 centimeters high, thinning will be done by spacing the tomato plants at 40 centimeters from each other. Weaker plants must be eliminated.
Sowing of tomato in pots
There sowing in pots should be done towards the end of March always using a soft and well worked soil. The seeds are placed on the surface and then covered with a thin or layer of earth and protected with a perforated sheet.
The soil must be kept constantly humid and the pot must be placed in a sunny place for many hours a day.
Tomato plant transplant
The transplanting of tomato seedlings is carried out in the month of May, when they have reached a height of about 15 centimeters (about 60 days). The distance between one plant and another must be at least 40 cm.
In case of broadcast sowing, the transplant will be done with bare roots, while in the case of plants coming from protected seedbeds we will proceed by planting them with all the bread of earth that surrounds the roots.
Lunar calendar for sowing tomatoes
When sowing tomatoes it is advisable to take into account the lunar calendar and to respect the phases of the moon.
Sowing done in phase Crescent moon ensures strong and vigorous plants an abundant production of high quality fruit.
If, on the other hand, the sowing of tomatoes is practiced in the phase of falling moon the plants obtained will have a stunted and contained growth and the fruits will be scarce and of inferior quality.
Tomato plant care
If the sowing of the tomato plants was carried out directly in the home, the seedbed must be protected during the night if the weather is still uncertain and the temperature is still too low.
When the tomato plants have reached a height of 30 cm, they must be supported with stakes and fixed to them, supporting their growth with special wire.
If the summer, a period in which the tomatoes swell and ripen, should occur at the height of the heat, it is advisable to protect the younger plants with shading and transpiring sheets, especially in the sunniest hours of the day.
Summer temperatures above 35 ° C often cause leaves to dry out and burn blisters on tomatoes.
Pesticide and pesticide treatments should be applied either early in the morning or after sunset, on unventilated days.
