cycle of above-ground parts of raspberry is 2 years.Pruning raspberries after fruiting stimulates the growth of new stems to replace the old, prevents the multiplication of pests and diseases.According to the technology of it's a little different for summer and autumn varieties.The best time for this procedure - the end of the summer or September-October.
Summer varieties
Summer varieties are very popular and very fruitful.The berries grow on the side shoots of biennial stems.Number of lateral branches depends on the growth of the stem: a long-stemmed them is much on the short - a little.
When planting the stem is cut to 25 cm from the ground.In the first year of fruiting shrub is not, therefore flowers on the stumps must be removed.From the land there will be new stems, which are thinned, leaving the strongest.Proper pruning raspberries in this period - it is trimming stumps to 25 cm to the ground.
year after planting shrub grows a number of strong stems that tie to the support wire.The upper row should be a distance of 1.5 meters from the ground.The plant begins to bear fruit.Pruning of fruit-bearing raspberries after the summer varieties produced to the level of the soil, as the stem "lives" only 2 years.Young stems thinned, leaving a 10 cm interval, and the wire tie.
Autumn varieties
Fruits of autumn varieties grow on the side branches, which are located near the top of the stem.When planting a plant is cut just as raspberries and summer varieties.Early spring is completely remove all the stems - it stimulates the rapid growth of young shoots that will bear fruit in September.Pruning raspberries after fruiting is to remove the above-ground parts of the bush completely.
There is nothing wrong - in the spring there will be young stems.Among them will be weak and, therefore, it is necessary to thin out the raspberries and leave only powerful shoots: so they will gather strength.If necessary, tie the plant to the wire.Since the growth, branching, fruiting varieties of autumn occurs in one year, the pruning is done after fruiting raspberries to the ground each year.
The annual cycle of development in remontant raspberries (autumn varieties) has advantages:
- do not have time to breed pests and diseases;
- not freeze the stems, as they are not in the winter.
there is a drawback: the short summer is not always enough to realize the potential of fruiting.Therefore, with the onset of cold weather in the branches can still be flowers and berries.
Stems remontant varieties can be left on for the second year of fruiting - they do not dry out, in contrast to the biennial.In this case, the young shoots will give the first crop, and shoots of last year - the second.Berries will not be much, but it happens elongation period of fresh fruit.
So, we examined how and when to cut the bushes.Pruning raspberries in the winter - is the removal of the two-year shoots of summer varieties and cultivars of annuals stems fall to the level of the soil.It must be remembered that all the cut branches are carried away from the site and burned, as otherwise they may cause the spread of pests.Take care of your plants, and they will provide you a high yield!
