At this time of year, gardeners are looking for trees with impressive autumn colour. A tree that will brighten the garden as we get ever closer to the darker days of winter. The beauty of having autumn trees in the garden is that it spreads the season and brings colour to the garden during a time when most flowers have long since finished their display. There is a perfect tree for every garden. Below is a selection of autumn trees that not only have great colour, but will suit small gardens and large gardens alike. Some present their colours early in the season and some later. In the list, there are a few rarer autumn trees amongst some well known types but all are suitable to grow in British and European gardens. We recommend going to visit gardens to see the tree in situ, before you buy it. It’s the best way to get a real feel for its appearance and height – a key factor to consider when choosing a tree for your garden.
Why do trees change colour in autumn?
The beautiful reds, yellows and oranges that light up both our natural landscape and our gardens in autumn are brought on by several changes. the days are shorter and the nights cooler, even before the first frosts. There also tends to be additional ground moisture at this time of year. As the tree begins to stop food production, the amount of green pigment in the leaf, which we know as chlorophyll reduces. The carotenoids (which produce the orange-yellow colours) and anthocyanins (which produce the reds and purples) become the stronger pigments, overwintering the green chlorophyll. This is what gives us the gorgeous, varied tints that we know as autumn colour. However, the autumn colour on trees is variable and relies heavily on some late summer rain. It is probably the most difficult season to predict, as it is often spread over a period of at least three months and its never the same from year to year.
How to choose the perfect autumn tree
- Think how long you’re planning to stay in your current property and how patient you are.
- Ask your neighbours about their experience of growing trees in their gardens. You might also be able to complement each other’s planting. Eg. not all trees are self-fertile, so if you plant the female, they could plant the male.
- If you’re buying a young tree, check it’s not pot bound and look at its shape. Make sure the top is nice and straight, and that there are enough side branches.
- If you’re buying a grafted tree, ask which type of roos stock was used – this may affect the suitability of your soil type.
- Plant when the soil is moist and frost-free, and water regularly during dry spells in the first growing season (from when the tree starts to leaf up until the leaves fall in autumn). Don’t make it ‘lazy’ by over watering.
- Stake the tree immediately after planting. If you need to prune, do so just before bud burst in late spring, to avoid infection.
- As a rule of thumb a tree’s root system is as wide as its crown. Be aware that shallow-rooting trees may get in the way of other planting ideas, and don’t forget to factor in sewage and other pipes when deciding where to place the tree.
- It’s always best to buy trees and shrubs from a specialist supplier to get the best advice on choosing, placing and caring for the most appropriate tree for your garden. It’s also worth visiting nurseries and arboretums at different times of the year to find the right tree.
- Remember its ultimate size. Always for a tree of a scale and shape that can be accommodated within the space you have in mind.
