Reference books by the gardener of last years unambiguously advised autumn redigging of beds. However some modern agronomists consider this occupation not only unnecessary, but even harmful.
Experts in physical geography agree in opinion that deep redigging of the soil with turning of layer of the earth breaks structure of soil and moves soil microorganisms which form humus, from poverkhyonost on depth. As a result they perish from the shortage of oxygen. In addition, at drought the soil dries and is carried by wind.
Meanwhile, many summer residents without fail till fall dig over beds after harvesting. Many of them thus just try to bring order on the site. Undoubtedly, the trodden soil overgrown with young weeds spoils all picture. If you are not concerned by future harvest, can safely undertake shovel.
Ideally before making decision on redigging it is necessary to study the soil on the site as all and depends on it. Heavy loamy soil with close groundwater occurrance on fall nevertheless should be dug over. It is better to make it prior to the beginning of the period of incessant rains. Otherwise you only condense the soil. Bury shovel when redigging approximately at 15 centimeters, no more. It is desirable not to overturn soil but only to shift layers, choosing at the same time roots of weeds. To remove all weeds in the similar way it will not turn out, but here many times it is possible to reduce their quantity.
Do not break large lumps as the glybisty surface will better detain moisture that will not give to swim away soil and to slezhatsya during rains. At the same time, in case of need, introduce "autumn" fertilizers and lime (bone, dolomite powder , etc.). It is better to carry out lime application in the fall that by spring there has completely taken place digestion of lime and it did not burn roots of sprouts and seedling and also did not harm reproduction of pochvoobrazuyushchy bacteria. Postpone addition of organic chemistry (compost, manure) until spring better.
To dig over the friable lungs abounding with humus and also sandy soils there is no need in the fall. Many experienced agronomists are sure of it. Instead just you porykhlit them mattock or rake. Only very littered places can be dug over garden pitchfork, at the same time choosing large roots of weed plants.
About two weeks later after loosening on beds there have to be shoots which can be destroyed easily chopper. Similar simple operation will allow to reduce quantity of weeds.
