Plant blackberries properly


The Content Of The Article:

To properly plant blackberries, you should pay attention to a few points. The berry bushes are nowadays offered almost exclusively with potted bales - so you can plant them almost all year round. However, a good planting season is the spring, when the soil has already warmed up, but the winter is still well moistened. Under these conditions, the roots of blackberries grow quickly.

Young plants of good quality have at least three healthy, fresh green basic shoots without injuries or dried bark parts. The pot bale should be rooted so well that when dropping no more earth drops, but at the bottom of the pot are also no turning roots to see. Turning roots are usually long and unbranched and run around the root ball along the lower edge of the pot. They are a sign that the plant has been in the pot too long. If in doubt, you should briefly remove the blackberry bushes in the nursery and inspect the roots for any defects. Pay close attention to the vigor of the different varieties, because growing blackberry breeds can easily blow up the dimensions of a small garden.

Blackberries on the bush

Bramble with big fruits

It took a couple of years for the first spineless varieties to match the classic 'Theodor Reimers' in terms of fruit quality and yield. Even today, there are still many hobby gardeners who prefer this undemanding barbel variety because of their high yields and sweet, aromatic fruits. Especially for fresh consumption 'Theodor Reimers' is still considered the ultimate. The medium-sized fruits ripen from late July to mid-September, in autumn 'Theodor Reimers' bears a beautiful, dark red to violet leaf color.
The thornless variety 'Loch Ness' is one of the best in terms of taste. It grows moderately strong and is less susceptible to fruit rot. After early flowering, the fruits ripen from late July to mid-September on the long fruit shoots of the previous year's rods. The very large, elongated blackberries are uniformly shiny black and taste sour-aromatic.
A milestone in blackberry breeding is the still young thornless variety 'Lubera Navaho'. It grows upright and is only about two meters high, so it comes out without trellis. The high yielding shrubs are robust and very healthy. The large, shiny black fruits ripen from mid-July and can be harvested into October. They are very firm and have an excellent aroma.

Soil preparation and planting

Plant blackberry bush

Loosen the soil thoroughly before planting and add some cornmeal or berry fertilizer to the planting hole

In particular, the thornless blackberries are a bit frost-sensitive and prefer a sunny to partially shaded, protected from Ostwinden location - preferably in front of a wall. Otherwise, blackberries are fairly undemanding and grow on almost any soil. Nevertheless, you should deeply loosen the soil in the bed before planting. Humus-poor and very heavy soil is best improved with potting soil or rotted leaves. The blackberries are dipped briefly in a bucket of water before planting, so that the soil ball can be soaked, and used depending on the growth strength with a row spacing of at least 1.5 meters. A handful of horn meal or berry fertilizer in the plant hole improve the nutrient supply. After carefully picking up the soil and potting it thoroughly, it is best to cover the entire bed with a layer of bark mulch about five centimeters thick so that the floor does not dry out. Finally, the shoots are cut with the secateurs to about half a meter.

The perfect trellis for blackberries

Brombeerspalier

A suitable blackberry palate is about man-high and consists of four to five tension wires. After planting, the shoots of the blackberries are cut back to the height of the first trellis wire

To ensure order in the Brombeerbeet right from the start, you should immediately set up a trellis and gradually channel the new shoots through. Without trellis the drive-jumble is with all varieties - except for 'Lubera Navaho' (see above) - to get after two years at the latest only with a radical pruning under control. Four to five horizontal wires stretched between man-high wooden posts with plastic sheathing have proved their worth. The distance between the tension wires should be about 30 to 40 centimeters, the first wire is attached to about 50 centimeters height above the ground. Do not choose the distance between the wires in the so-called fan training, because then you can weave through the blackberry shoots, without having to fasten them extra.

Note that particularly fast-growing varieties such as the large-fruited 'jumbo' need about five meters per trellis per plant.But they are also so productive that you usually get by with a single shrub.

Education of blackberries on the trellis

During the summer, the newly planted blackberries form new shoots, of which only the five to seven most vigorous are preserved and are gradually led fan-shaped through the trellis. Once the shoots have grown beyond the topmost tension wire, you just cut off the protruding. Next year, the leaf axils form short side shoots with terminal flowers and fruits. After harvesting, they are cut to ground level and, at the same time, the new rods are harvested for next year's harvest. The rods of strongly growing varieties form up to one meter long side shoots in the first year, but only bloom and fruit in the following year. Cut these side shoots consistently in the first year to two or three buds, so that the shrub is not too dense and the fruit can mature well.
