Why did my acorns stop growing?
1) Environmental conditions, such as heavy spring rains, growing season flood events, drought, and unusually high/low temperatures, can cause poor acorn pollination, acorn crop abortion, and complete acorn crop failures.
How old are the trees at Wistmans wood?
Because of the age of the woodland – the oldest oaks are estimated to be between 200 and 400 years old – it has a well-established ecosystem: the site is noted for its lichens, mosses and ferns, many of which are growing on and in the trees and can be seen hanging from the branches.
How big is Wistmans wood?
The oaks grow barely taller than 5.5m (18ft) high, and their tangled branches and the uneven rocky floor make it impossible for Dartmoor ponies and cattle to enter. This is the main reason why the wood still exists on the moor – its inaccessibility keeps it protected from destructive grazing.
Why are there no trees on Dartmoor?
For much of its history, Dartmoor has been pretty much uninhabited. After the chaos of earthquakes and volcanoes, Dartmoor became almost entirely covered by trees following the last Ice Age 12,000 years ago. They would make clearings in the trees to attract the animals to graze.

What does it mean when an oak tree drops a lot of acorns?
If you’ve got oak trees in your yard, you probably are familiar with the task of raking up tons of acorns in the fall. If your trees are shedding acorns prematurely it’s a sign that they are focusing their energy on other things rather than seed production.
Why are the leaves falling off my red oak tree?
Oak wilt affects both red and white oaks but is more common in red oaks. This deadly disease first appears as wilting of the leaves in the late spring and early summer. Dead leaves fall from the tree and cause heavy areas of defoliation, leaving the oak branches bare. Dead branches often develop dark streaks below the bark.
What can slow down the growth of an oak tree?
Excessively shaded environments may slow the growth process. Grow oaks in acid, well-drained soil and avoid extremely wet conditions that may increase susceptibility to disease. The growth rate of oak trees varies greatly depending on the particular species.
Are there any problems with the oak tree?
Many oak species that we use within the landscape are native. Unfortunately, native does not translate to problem-free. Oaks are vulnerable to a number of insects, pathogens and abiotic problems.
What happens to oak trees in the summer?
Wateringdoes not kill oak trees. Summer wateringcan predispose oaks to various diseases, but only if a pathogen is present. In drought years, summer wateringcan maintain health and vigor of oaks in landscapes. This year may be another drought year, so keep this in mind for summer irrigations. Oak trees do not go “dormant” in the summer.
