If you want to plant a tomato variety with limited growth on a plot or in a greenhouse, you should pay attention to Long Keeper. One of the main advantages of this plant is the high marketability of its fruits.
Description of the variety
Long Keeper is a determinant type that can be planted outdoors. Different types of greenhouses are also suitable for it.
The bushes reach medium size, do not grow more than 150 cm. The foliage is green, also medium in size. The inflorescence is formed simple, the first is formed above the 7th leaf, then every one or two leaves.
Long Keeper tomatoes for universal use.
The main qualities of the fruit
This variety has a difference - in an unripe state, the fruits are whitish, and not habitually green. When ripe, they are white-orange. The maximum weight of Long Keeper tomatoes is 130 grams. Up to 6 tomatoes are formed in one brush.
The tomato is popular due to its dense pulp, which is ideal for canning as a whole.
After harvesting, the fruits can lie under certain conditions for up to 130 days without losing their presentation.
Taste characteristics
Long Keeper has a pleasant tomato flavor.
Ripening and fruiting
This variety belongs to the late ripening. Ripens in a maximum of 130 days.
Yield
The yield is estimated at 6.2 kg / sq. m or 80-100 t / ha.
The timing of planting seedlings and planting in the ground
In March, you can already plant the seeds of this plant for seedlings. When young plants reach an age of 60-65 days, young tomatoes are planted in the ground.
Growing tomato seedlings is an extremely important process, because it largely depends on whether the gardener will be able to harvest at all. All aspects must be taken into account, from seedbed preparation to planting in the ground.
Landing scheme
It is allowed to use the 40x60 cm planting pattern that is standard for most varieties.
Growing and care
Before planting a plant in a greenhouse, it must be processed. The benefits of sulfur disinfection are obvious. It helps to destroy fungus, infection, mold. Mix a few pounds of sulfur with a little gasoline in a deep iron bucket. Set fire to the mixture and leave in a closed greenhouse house to slowly smolder for 5 days.
You need to start preparing the soil for planting Long Keeper tomatoes in the fall. You can disinfect the earth with boiling water, a solution of copper sulfate or ash.
Long Keeper Bushes require formation. Only one stem is left, it is no longer required, otherwise the plant will be overloaded, which will affect the size of the fruit in a negative direction.
And you will also need to dig up the beds in advance, fertilize them well with slurry or bird droppings, and organize passages between the beds.
In the spring, before planting Long Keeper seedlings, the rows need to be insulated with straw or last year's leaves. This is done because young plants take root better in warm ground.
And also professionals advise to carry out disinfection "Fitosporin-M". Feed the soil with compost or compound fertilizer.
The temperature in the greenhouse must be maintained at + 18 ... 25 degrees. It's not scary at night if it falls by 3 degrees. Although Long Keeper tomatoes require warmth, too hot air and soil always negatively affect the overall health of the plants.
It is imperative to regularly ventilate the greenhouse. The best time is in the afternoon, after watering has been done, then the air humidity will not increase. The soil inside requires constant loosening in order for oxygen to enter the roots.
Long Keeper is sure to be stepson, but this procedure is required to be carried out correctly, following the recommendations of experts:
the tool used for trimming must be sharpened and disinfected, you can use potassium permanganate;
stepchildren are cut exclusively from top to bottom, the remaining stump should be 10 mm from the main shoot;
excess shoots are taken out of the greenhouse, since they are a breeding ground for pathogenic microorganisms;
before pruning each new bush, the tool is disinfected again.
The procedure is carried out on a regular basis throughout the season.
In order for the harvest to turn out to be great, the land for planting tomatoes must be well fertilized with organic matter. Each stage of soil preparation requires a certain type of fertilizer.
Many gardeners use ash instead of fertilizer. This is still the old-fashioned way, when people could not buy dosage mineral preparations in the store. Top dressing with such a natural mineral fertilizer has its advantages. Plant residues, as well as wood ash, contain a lot of phosphorus and potassium, several dozen other trace elements that have a positive effect on Long Keeper fruits.
The richest in composition is ash from potato tops - it contains more than 20% potassium, about 10% phosphorus, and one third of it consists of lime. All these components are necessary for this tomato variety. Usually, ash is introduced into the soil during digging in the fall, so its effect persists for another 2-3 years. At the same time, it slowly reduces the acidity of the soil and inhibits the development of some pests.
And also the method of feeding Long Keeper tomatoes with ash during planting of seedlings is used, which has its own advantages. Add 2-3 tablespoons of sifted ash to the hole, mix thoroughly with the ground so as not to burn the roots. It is desirable that the plant at this moment has 7-8 developed leaves.
With an interval of 2-3 weeks, you can feed with already dissolved ash - 1.5-2 glasses are stirred in a bucket of water. Pour a liter into the grooves around the bush. Such fertilization is appropriate during flowering and during fruiting. The ash solution can be alternated with other dressings.
The use of iodine as a fertilizer has become very popular in recent years. Benefits include safety and disease prevention. Feeding Long Keeper with iodine is justified by the fact that this element improves nitrogen metabolism, that is, the plant assimilates nitrogen from the soil better. And also watering tomatoes with water containing iodine improves immunity against root rot and late blight.
Seedlings can be watered with a solution. For 3 liters of water there is 1 drop of iodine. After planting Long Keeper tomatoes in open ground, they can be watered with the same solution at the beginning of the formation of inflorescences. Thanks to this nutrition, the brushes will form with a large number of fruits, and the fruits themselves will grow larger.
A plant needs different micronutrients at each stage of growth. All fertilizers can be divided into two groups: mineral and organic. Folk remedies are often used: iodine, yeast, bird droppings, eggshells.
It is important to observe the rate and period of feeding. This also applies to folk remedies and organic fertilizers.
Disease and pest resistance
To protect the plant from pests, an insecticidal soap is used to prepare a spray solution.
Tomatoes are protected from most pathogens by fungicides, they are used from the moment the seedlings are planted and then every 10 days until the fruits ripen.
Growing regions
Due to the fact that Long Keeper can be grown in a greenhouse, it is widespread throughout our country.
