Gardeners and gardeners know that the success of the harvest by 90% depends on high-quality seedlings. But each culture requires a special approach and has its own time sowing to seedlings. Do not trust universal advice. It is necessary to analyze several factors and withdraw a more or less accurate date of sowing.
1
When determining the date of sowing, take into account the estimated transfer date of seedlings into a constant soil. Keep in mind that seedling on protected areas of the soil is planted in about 10-20 may. If the soil is open, you have to wait until June 10, not before.

Consider the duration of the growing season for the plant, in other words - the timing from the appearance of germination to harvest. Each plant has their own, but in the middle of the first sprouts will have to wait 3-15 days. All cultures are divided into early, secondary and late. Also, "late" varieties will need more time to ripen fruit. Also, do not forget to take into account the "age" of the culture in which it can be transplanted into the soil at a permanent place.

Each plant has its optimal age to transplant in the ground. So, tomatoes are 40-70 days, depending on the variety, pepper - 50-65 days, eggplant will be needed 45-60 days. Do not forget that after picking or transplanting your plant will be for several days to "root." Give him time to adapt and shoots. And, consequently, consider these days in your formula.

Also consider the climate of your region in your calculations and the requirements of a particular culture to heat. The most favorable for the appearance of the first germs is the temperature of + 20-22 degrees above zero. If the temperature is lower, shoots are delayed.

The temperature of the soil is also an important factor that should be considered when disembarking seedlings. The so-called "physical ripeness" of the earth comes when its temperature at a depth of 8 centimeters is equal to 8 degrees with a plus during the daytime. To measure it, it is enough to dig a hole and lower the thermometer into it. In other way, finding out the "ripeness" of the Earth is to monitor birch leaves - they must dissolve. You should also feel the land: if you feel cold when working with it, but your hands do not freeze, it means that she is ready for reception seedlings.

So, as an example, we calculate the approximate terms of the seedlings of celery. It should be planted in the soil until May 25. We take away from this number the optimal age of seedlings is about 70-80 days, add days from sowing to the first shoots - about 15 days, as well as 2-3 days on the adaptation of seedlings after disembarkation. Now dated May 25, take 90-95 days. Landing time Celery seedlings - February 25.
The duration of the growing culture is usually indicated on sachets with seeds. So it will be easier for you to "fit" the timing of harvesting to a specific date. And remember: it is better not a little bit expensive saplings than outgrowing. They will be less susceptible to diseases and are easier adapting to new conditions.
