Growing Oak Trees

In this article, we explain the process of growing Oak trees!

Growing Oak Trees – The Process

In our experience, growing oak trees from acorns is surprisingly easy. So easy, in fact, that we saw little reason in using a specialist UK propagator.

Once the acorns have grown into seedlings they are transplanted into rows with wider spacing to facilitate strong growth. As they mature, we transplant them twice more. This helps build a healthy, well-developed root system. By keeping the entire process in-house, you can also reduce the risk of exposure to serious diseases like Oak Processionary Moth.

One recurring challenge when growing oak trees is their natural tendency to fork out. They often fail to grow straight, lacking what’s called “apical dominance.” One method to correct this is planting trees close together. This encourages upward growth as each shoot reaches for sunlight. But tighter spacing reduces airflow, which increases the risk of mildew in summer. This can severely slow growth.

The best solution? Use a strong bamboo cane and tie the top shoot to guide it upward. It’s labour-intensive work, but it produces a clean, straight stem. Most customers never see the effort that goes into creating such a fine specimen.

Is it as easy with other species?

Not always. Oaks are generally easy to grow compared to something like Elm. When we grew our own Elms, we partnered with a Scottish lab. They used meristematic tissue to produce around 2,000 seedlings in test tubes. It took three attempts before we finally had success. A much trickier process than growing oak trees from acorns.

Oak Processionary Moth

Oak Processionary Moth (OPM) is a serious concern within the tree industry. The caterpillars of this moth have tiny hairs that can cause skin irritation and even respiratory problems in people. First detected in London, OPM has since spread, triggering strict movement restrictions on Oak trees with a girth over 8cm. Because of our location within a protected zone, we are not allowed to ship or sell Oak trees of that size outside the area.

As a Plant Healthy certified nursery , we take plant health and biosecurity seriously. To comply with current regulations and help stop the spread of OPM, we’ve made the responsible decision not to stock Oak trees over 8cm girth. However, we can still supply smaller, younger Oak trees that fall within permitted guidelines.

If you suspect a case of OPM, don’t touch the tree or caterpillars. Instead, report it immediately to the Forestry Commission!
