Pruning
First of all, regularly it is recommended to do pruning of the bushes. Pruning raspberries – a procedure that can make growth not so pervasive. Clipped raspberry just. This is due to the feature of plants forming crop on biennial shoots, which die after fruiting. Then they need to be cut to the ground (even capturing a little deeper). Together with them, remove excess, dead, weak, damaged branches. Clipping is recommended in the fall.
All the young shoots that appear around the bushes, it is necessary to ruthlessly remove the root or cut as deeply as possible.
If raspberry bushes are old and neglected, this will not be enough. This procedure may even trigger the growth of new shoots. To clean up the old raspberry patch, you may need a couple of years, during which the stubborn young have to dig.
Barrier to roots
To limit the expansion of the raspberries on the site or to protect it from her neighbors, experienced growers use the following method. Along the row of raspberry dig a narrow deep ditch and put the slate, plastic, metal or tar paper. The groove needs to be deep – not less than 70 cm.
Movement and rejuvenation
More creative method of exercise and rejuvenation. The process is labor intensive, but worth it – it kills two birds with one stone: limits the raspberry bushes and rejuvenates it.
It all starts with planting. Plant bushes in a single row on the edge of the proposed land for raspberries. When it begins to creep growth, shoots growing five feet closer to the parent hive, destroy. Of the other to form the following series. And so repeat until, while space allows.
Why is it good? Rejuvenation occurs naturally raspberry. The bushes remain to rise in their places, they need not be transplanted without damaging the root system. They are less damaged by pests and less likely to get sick. Shrub begins to "move" and give excellent yields.
When laying the last row, the first is destroyed. And when the bushes reached the border of the allocated land or the neighbor's fence, you can use the method of dropping of slate or roofing material.
