The black pine does not let its gardener down. The decorative conifer impresses with its rapid growth, uncomplicated care and robust resistance to diseases. A good-natured cutting compatibility rounds off the profile. Read here how to prune a Pinus nigra in an exemplary manner.
When and how should you prune a black pine?
A black pine should ideally be pruned between mid-May and early June. To limit growth or maintain shape, shoots can be shortened by up to two-thirds and candles can be halved. Dead wood should also be removed.
The best time is after budding – tips for choosing a date
Mark your cutting schedule one day early between mid-May and early June. At this time the tree has largely completed its budding this year, so you can easily estimate the extent of the pruning. At the latest when the needles begin to unfold along the candles, the pruning shears (€39.00 on Amazon) should be brought out.
Cutting Guide
First of all, it should be noted that a black pine does not necessarily have to be cut. Where the tree has enough space, it will take on an impressive stature over the years. In order to cultivate a Pinus nigra as a topiary or to limit its growth, annual pruning in May is recommended. How to do it right:
- In order to regulate the growth height and width, shoots that are too long are shortened by up to two thirds
- To promote a bushy, compact habit, simply cut the candles in half
- At the same time, dead wood is thoroughly removed to prevent aging
If you don't mind the time commitment, don't cut off the new growth with pruning shears. Since he althy needles are not spared with this cut, the candles can be broken out individually by hand. If you radically cut back the branches, please make sure that there are at least 5 to 10 pairs of needles below the cut point. Otherwise, the black pine will have a hard time sprouting again.
Tip
The high pruning tolerance, combined with excellent winter hardiness, make the black pine the ideal bonsai for outdoor use. With a little skill and a good eye, you can transform a Pinus nigra into an evergreen work of art that will attract everyone's attention in the creative garden.
