Yew needles strong - Why does the yew lose needles?
If a yew needs a lot, it does not always have to be a sign of illness or care. Often very natural causes are responsible. Of course, diseases or pest infestation can cause the yew to lose many needles.
Yew loses needles - what causes it?
Every four to seven years, gardeners complain that the yew is heavily needing. Often the whole ground is covered under the tree. Falling the needles, especially in the interior of the yew, it is a natural cause. The yew throws off the old needles.
Yew disease is very rare and usually due to care mistakes.
If the fresh needles turn brown or yellow and are thrown off, you should definitely look out for pests or fungal infestations.
Detecting pests of the yew
Lice, especially scale insects, occur more frequently. While you can usually see lice with the naked eye, scale insects are very tiny. Watch for ant trails leading to the stem of the yew tree. They are a sign of lice infestation.
Fungus diseases of the yew
Fungal infection rarely leads to needle drop. Mostly the needles turn yellow and soft. Treat a fungal infection by cutting back the yew.
Yew needles heavily because it has dried up
A more common problem with yew care is dryness. The tree evaporates a lot of water over the needles. Does not get enough moisture in dry times, dry up the needles and fall off.
This also applies to the winter. That's why you should think about the yews in the garden on a frost-free day in winter.
Older trees usually require no additional care. They can provide themselves well with their long, deep roots. Only younger and freshly planted yew trees should be watered and fertilized regularly.
Tips
A weakened yew suffers particularly from diseases and pests. Make sure that the yew gets enough nutrients through fertilizer. Water in very dry times without waterlogging.
