How to triple your tomato crop without chemicals
To improve the harvest without the use of chemicals, you need to be well prepared for the garden season. One of the conditions for large yields is a properly organized garden bed. The beds should be carefully prepared for planting seedlings. Warm beds have proven themselves well: cardboard is laid at the bottom of such a bed.Then a layer of sawdust about 10 cm is loaded on top. Hay or fresh grass is placed on the sawdust, a layer of 30 cm and rammed.
Sifted humus or compost mixed with ash and earth from the site is the top layer of the bed. It should be about 20-30 cm, but more is possible. Warm beds only need to be watered. They work great for 3 years without adding any additional fertilizer.
Planting seedlings in a permanent place is best done when the seedlings reach 25-30 cm.
For 1 sq. m optimally plant from 3 to 5 tomato bushes. Thickening of planting tomato also leads to yield loss.
Irrigation is carried out only with warm water, as sudden changes in temperature provoke a decrease in plant tone and disease.
