Why is there even the idea of planting ground cover against blackberries? Because blackberries grow so wildly that they are almost impossible to control. But if ground cover plants occupy the space around their roots, it can no longer be possible to take up more space, right?
Do ground covers help against blackberries?
Ground cover plants areno serious competitionfor blackberries, as they are very vigorous. You can better control the spread with aRoot Barrier, pot culture or a lawn area. Otherwise you have tocut the shoots regularlyandtie them up Plant preferably upright growing varieties.
How can I control the spread by sowing lawns?
The grasses themselves can do little to stop the growth of the blackberries. Once a long, overhanging cane reaches the ground, it will form roots at the point of contact. Root runners can also penetrate the lawn very easily. The advantage is that whenmowing the lawnthe blackberry canes sprouting between blades of grassare also mowed down so that they cannot grow larger.
Is it true that other types of berries make good underplanting?
Yes, many different types of berries have similar requirements in terms of location, soil and care, and can therefore thrive well as plant neighbors. Since blackberries form long tendrils in the garden, they can be easily planted under low-growing berry bushes, for example currants. But when it comes to uncontrolled spread, this combination is only of limited help. Regular cutting and tying cannot be avoided.
How deep does a root barrier have to be for blackberries?
Blackberries that form runners should be planted with aat least. Get a 30 cm deep root barrier. This must be made of thick, durable foil so that it cannot be broken through.
How do I care for blackberries so they don't spread?
Limit the volume of a shrub every year as follows:
- only leave 4-6 new rods in summer
- Maximize side shoots
- Tying rods to a scaffold
- they shouldn't touch the ground
- if applicable shorten the length
- removing worn fruit canes
Thickets that have already formed should be thinned out as quickly as possible with a brush cutter so that they do not become even more overgrown.
Which blackberry varieties do not climb?
Popular upright cultivars include 'Asterina', 'Black Satin', 'Choctaw', 'Navaho', 'Ouachita' and 'Wilson's Early'. There are also semi-upright growing varieties such as 'Chester Thornless', 'Loch Tay' or 'Loch Ness'.
Are ground cover plants useful under blackberries in other ways?
Ground covers under blackberries can suppress weeds. In sunny locations they can protect the root areafrom drying out. This is important because blackberries have shallow roots.
Tip
Do not put blackberry clippings in the compost
Blackberries have a strong urge to reproduce. You should not not compost the clippings, as they will find a chance to take root again even in the compost heap. Don't leave it in the bed for a long time either. Instead, it is better to burn it as soon as possible or dispose of it safely in another way.
