Which Tomato Variety To Choose?
You can’t just buy any tomato breed and seed it. You need to choose the breed, which is resistant to any kind of weather – sudden frost, drought, heat, too much humidity.
There are also early and mid-early tomatoes. Later varieties do not have time to mature before frost or too cold weather. In eBay or similar shops, you can buy almost all kinds of tomatoes, they just differ in color, shape, pulp density, size, and nuances of taste.
Tomato breeds for growing outside have low determinant shrubs. You can plant them in simple soil and don’t need to fix them. But there is also a breed that needs fixing. You need to tie up not only the stalks but also branches with heavy fruits.
Indeterminate plants are tomatoes that produce fruit onward the length of the plant. Determinate tomatoes are just a bush with tomatoes that have fruits only at the end of branches only.

Growing tomatoes in the open ground include earlier seed sowing for seedlings. Typically sowing begins in late February or early/middle March. The seeds should not be too old. Best tomatoes are grown from seeds that are 2-3 years old. You need to disinfect the seeds and put them in a liquid growth stimulant for 12 hours.
Soil preparation begins 10-14 days before planting. Tomatoes prefer light and fertile soil. It must contain sand or topsoil too. Before planting tomatoes, lose the soil and shed it with potassium permanganate. This treatment kills harmful microorganisms and insect larvae. Tomatoes will not get diseases because of this step.
The yield of tomatoes depends on the nutrition level of the soil. It’s recommended to add humus, wood (preferably birch) and ashes. You can also add fertilizer, for example – superphosphate, or potassium sulfate.
Seeds were sown in deep trays. Each seed is in its own container if the container is small in diameter. If you have a bigger pot or box, you can add as much as you want, but remember the distance – 4inch. Sowing in small pots is better because when you are taking it out, you will not break its root system as you would in a bigger pot.
Tomatoes can be grown awesomely in paper cups, peat pots, sour creme pots or any kind of small container.
Taking care of seedlings is easy. After sowing immediately cover them with a film and place it into the heat. Successful germination will be when seeds are 1,5-2 long. When they reach that length, put them in bright light. You need to protect them from drafts and direct sunlight.
Watering – use only warm and soft water -preferably rainwater.
When tomato seed has deployed two leaves, replant them into individual pots. This needs to be done only if you sow them in a large box or pot. When you have done transplanting, feed them with fertilizer. They will get stronger and stronger. It also stimulates the immune system.
2 weeks before transplanting them into open ground, you need to harden seedlings. Bring them to the balcony or veranda once per day. On the first day for 1 hour, the next day for 2 and so on. Then put them outside all day if the weather is good. If you will do it right, you will see that plants are getting bright green.
Transplanting Tomatoes Into The Ground
[amazon box=”B0063YSYZK” template=”horizontal”]
For the successful breeding of tomatoes, it is important to choose the correct place where to plant them. Do not plant tomatoes in the areas which were occupied by eggplant, potatoes or other nightshades. Tomatoes love bright but diffused light. If they are in shadow, they will not grow. It’s important that the soil does not drown in the water so choose a place where water can get out of the garden. Consequences of that are black stem, dead roots, vertex or botrytis. Feel free to add nutrients to the soil. Tomatoes need a lot of vitamins.
Plant tomatoes in the ground when the soil is warmed up. Soil temperature needs to be above 15 degrees (59 Fahrenheit). Typically, such a soil temperature reaches close to the end of May.
You can warm up soil manually too. Just cover desired tomato spot with two layers of polyethylene film. It will get soil war faster and will prevent the growth of weeds.
A week before planting, the soil should be loosened purging it from the remainder of weeds and/or plants. Planting can’t take place if the weather is hot. If it’s hot, do it in the morning or late evening. Better morning. Cloudy days are the best days for transplanting.
Tomatoes that are ready for planting should be strong and not overgrown. Seeding must be at least 6 inches tall. Take a look at all plants and check if they were not affected by pests or were not hurt somehow. Take tomato plants carefully. They are easy to break. Overgrown tomatoes will have many leaves. Remove 2-3 leaves. It will allow flowers and other leaves to spread bigger.
When planting, do not plant more often than every 23 inches. If you have small bush tomatoes, then plant in every 15 inches. Do not go under 15 inches. Planting is as same as you did when putting them in separate pots. When you are putting tomato plants in the soil, pour some kelp meal and some bone meal into each plant spot. It will give them a growing kick.
Fill the hole with the soil and slightly press it with the hand. Cover the top of the soil with a thin layer of peat. Tomatoes after planting should be watered with warm water. That’s all about planting.

Taking care of tomatoes in open ground is as same as if they were in a greenhouse. Except for one condition – they don’t need ventilation. If the weather is getting too cold, you can cover them with a film, but that’s not necessary.
If you are planting tomatoes in the open ground, prepare for weather changes. Care includes – regular watering, fertilizing and timely removal of weeds.
Tomatoes will need time, but not excessive watering. Monitoring rain is important. If you will water tomatoes and after 15 minutes it will start to rain, there will be too much water and tomatoes can start to rot. Use only warm water. If you use cold water, it will shock plants and they can die.
The yield of tomatoes depends on the nutrition level in the soil. You need to feed the soil 2 weeks after planting tomatoes in the ground. Use full complex fertilizer with a high content of phosphorus and potassium. Read this article about lawn fertilizers. Suitable superphosphate, or potassium sulfate. After fertilizing, you need to water tomatoes a lot. You need to wash away fertilizers from the stems and leaves. If you do not wash them away, they will burn plant, and it will die.
Industrial insecticides are good pest killers. It destroys thrips, spider mites, whitefly. The good thing is that in the open ground tomatoes get diseases less often.
