Common Mistakes in UK Food Forests – Neglecting Soil Health
Creating A Thriving Food Forest In The UK Is A Rewarding Way To Grow Your Own Fruit, Nuts, Herbs & Perennial Vegetables While Working With Nature, Not Against It. But We Need To Stop Neglecting Soil Health.

However, even experienced gardeners can make mistakes that hinder their forest garden’s success. In this article I’m looking at problems associated with Neglecting Soil Health.
Soil health is critical to the success of growing plants, whether in gardens, allotments or food forests. Healthy soils lead to healthy soil microfauna and that leads to healthy plants. They are intricately entwined and interdependent.
Here are some of the elements we need to consider in the bid to maintain healthy soils.
Neglecting Soil Health By Ignoring Organic Matter & Mulch
A healthy food forest depends on rich, living soil. Yet, many gardeners overlook the importance of soil organic matter and mulch, which are essential for retaining moisture, suppressing weeds, and feeding soil life.
In the UK’s often damp—but increasingly drought-prone—climate, a thick layer of mulch (such as wood chips, straw, or leaf mould) helps regulate soil moisture. Without it, heavy rains can leach nutrients, while dry spells leave plants struggling.
But maintaining organic matter goes further than these rather text book like explanations. Organic matter is at the core of a forest or woodland. It is formed by the leaf cover of autumn leaves that clothe the forest floor. It is the natural way that trees recycle nutrients and build the soil around their roots. It is also at the heart of permaculture.
Using grass as a mulch
Solution:
Apply a mulch layer when you start your food forest. Especially if the area under your trees is grass or other herbaceous cover. You can add a layer of cardboard first if you wish but we found no difference long term provided a deep layer of mulch was added the first time. I prefer wood chip and apply a 15-18cm layer of mulch in the first year with a thin top up as needed annually thereafter.
Use forest made compost to boost fertility naturally. I’m not keen on bringing in fertility as this is meant to be a natural self sustaining system. But compost organic material if you wish OR just cut and drop to keep the surface covered. The growing of cover crops and green manures also makes perfect sense as soil should always have living material in it.
Let fallen leaves decompose in place—nature’s own mulch! Sometimes life is that simple! Why fight nature?
Relying on Chemical Fertilisers & Pesticides
It’s tempting to reach for synthetic fertilisers for a quick boost or chemical sprays to tackle pests. But these shortcuts harm the delicate balance of a food forest, killing beneficial insects, fungi, and bacteria that keep the ecosystem thriving.
British gardens and forests are home to creatures like birds, ladybirds, ground beetles, and earthworms—all vital for pest control and soil health. Chemical inputs disrupt this harmony, leading to long-term problems like resistant pests and lifeless soil.
Solution:
Biodiverse planting where the more biodiverse the planting the healthier the plants are. think of it like this, in a monoculture the post can easily move from host plant to plant. But where the host plants are more widely spaced, with other species planted densely in the “spaces”, it is really hard to move from host plant to host plant.
Some people argue that we should use natural fertilisers such as comfrey tea or seaweed feed. I’m not convinced. Seaweed isn’t a natural forest constituent and has no place on a forest in my mind. And do we really need tomato a plant tera of any sort. It doesn’t happen in nature and we should be able to grow a food forest without all the faff that goes with this. Just mix the plants together and lets them help one another. Let the dead leaf of plant feed the growth of its neighbour.
Encourage predatory insects partly by planting nectar-rich flowers (e.g., yarrow, fennel). But more importantly in some senses, by providing a varied habitat that encourages a natural balance of pests and predators. Predators actually need a few pests or they will not have anything to eat themselves. If we eliminate all the pests the predators starve! That isn’t how nature should work.
Overlooking Soil pH & Needed Amendments
The UK has a wide variety of soil types—from acidic peaty soils in Scotland and on the Fens to alkaline chalky soils in southern England. Many fruit trees and forest plants have specific pH preferences, and failing to understand your pH can lead to poor growth or nutrient deficiencies. Testing is available but the gardener with a good eye can observe what is growing naturally and judge pH reasonably well from that. Eg if there is a lot of heather growing between the tress then the soil is likely on the acidic side.
Then think about wha you can plant. For example: –
Blueberries thrive in acidic soil (pH 4.5–5.5).
Apples and pears prefer slightly acidic to neutral soil (pH 6.0–7.0).
Brassicas (like perennial kale) do best in neutral to slightly alkaline conditions.
These are rules of thumb but work well as guidelines.
Solution:
Test your soil pH , kits are cheap and easy to use but not very reliable. So making use of professional labs makes sense if you need accurate results.
A lot of books talk about amending the soil pH. But should we be doing that in a food forest by adding sulphur or lime? I think not. Far better we do it slowly by the plants and crops we grow OR we just grow what suits our soils and cut the faff from this food forest way of life!
Final Thoughts
A successful British food forest works with the land, not against it. By prioritising organic matter, avoiding chemicals, and understanding your soil, you’ll create a resilient, low-maintenance forest garden that produces food for years to come.

Thanks. My research shows that many foods have low calorie levels or use higher levels of calories to digest. But none appear to be truly negative.
