Garlic is very vitamin-rich also microelements, however additional nutrients sometimes are necessary for him. If leaves of garlic begin to turn yellow - important in due time to establish the reason and to eliminate it to provide good harvest.
Low temperatures
If it is wrong to choose date of landing of winter garlic, that is to land towards the winter too early, then he will manage to give escapes which will unambiguously turn yellow together with growth of root system. In that case, yellowing of leaves will not extend to healthy leaves. And summer garlic which lands in the spring also can be subjected to frosts in case it is landed too early.
Shortage of active agents
Yellow leaves of garlic can indicate the shortage of nutrients also. Such result can be received at disembarkation of garlic to not fertilized or badly paved way. If the reason of yellowing of escapes in it, it is possible to enrich the soil by means of complex mineral fertilizer. For this purpose it is necessary to proborozdit row-spacing on several centimeters, to fill up in it the granulated urea, and after to cover with earth and to spill carefully. Thus, the soil will become impregnated with useful substances and the yellowness of garlic has to stop.
Moisture surplus
One more important reason for which garlic turns yellow is violation of water balance. Most often it occurs in the spring at long rains. Garlic extremely badly transfers moisture surplus. Therefore it is important to observe the watering mode also. In normal climate in the spring garlic is enough to be watered once in two weeks. It is possible to increase amount of water only in case of long droughty days or high temperature of air.
Fungus
If leaves of garlic have begun to turn yellow without the visible climatic reasons, then it is impossible to exclude availability of fungal defeats. As a rule, fungal decay – fusariosis has such symptoms. For its prevention the teeth before landing ret in potassium permanganate solution for 15 minutes or in Fitosporin for 7 minutes.
