It is known that gooseberries are well propagated by layering. But the percentage of rooted cuttings is small. That's because woody cuttings lose the increased ability to rooting, which the layers have.
Scientists have proposed a new way of rooting cuttings - combined cuttings. To do this, cut from the bushes lignified cuttings with two or three green shoots. They are placed in grooves with a depth of 8-12 cm, spilled with water. Green shoots that are above the surface of the soil, shortened to 3-5 cm and well watered.
During the whole rooting, it is necessary to maintain a high soil moisture. For this landing watered three times a day - in the morning, afternoon and evening. In this case, the formation of roots begins two to three weeks after planting the cuttings. Then the number of waterings is reduced to once a day, and then completely stopped. Usually, by the end of rooting, the buds start to grow and grow to 10 cm by autumn.
The following year, the cuttings are fed ammonium nitrate at the rate of 20-30 g per 10 liters of water. When reaching the tops of the shoots of a height of 15-20 cm, the cuttings spud the first time. Then this operation is repeated two more times.
In October, the cuttings are dug and cut with a pruning shear for the number of shoots with roots. As a result, two or three saplings are obtained from each cutting. Someone will say that layering is easier to root. But in this case, the root system is not so powerful, and the seedlings start to bear fruit only in the third or fourth year. When growing combined cuttings, seedlings begin to bear fruit one year after planting.
