Conifers in your own garden are always very popular. If the garden is big enough, you can let off steam in this area. But beware: You should already pay attention to a few things when planting the trees.
Distance to neighboring plants
So you have to make sure there is enough distance to neighboring plants, because if the trees are placed too close together, then yellow needles can develop very quickly. If you notice this on your conifers, then first check whether other plants are too close.
Avoid shadows
You should also check whether the tree is not in too much shade, meaning that the branches are not getting enough light. If yellow needles are observed, the shoots should be thinned out. But only the ones that have grown too dense.
Protect branches from damage
Also check whether the knots are damaged and that might be the reason for the discoloration. If this is the case, then cut off the damaged branches.
Check trees for pests
Finally, you should check whether you can spot pests on the needles or branches. These can also cause the yellow color and the subsequent death of the branch. In the case of pest infestation, a specialist should take a look at it. Since there are too many pests, no general statement can be made here.
