Looking After Our Trees

Trees For Small Gardens

Trees make a valuable contribution to gardens, providing shape, colour, shade and visual interest in built-up areas. They also help wildlife by providing nesting sites, food and pollen, as well as the atmosphere by absorbing and retaining carbon and releasing oxygen. Factors which need to be considered carefully when selecting a garden tree include; height, spread and proximity to buildings; visual appearance; environmental impact; and maintenance needs.

Height, Spread and Proximity to Buildings

The height and spread of a selected tree must be judged in relation to its intended position and closeness to buildings. Guidance on currently recommended safe distances of different species of trees and their heights from buildings can be found on various websites including:

Trees and their recommended safe distances

Guideline Distances from Development to Trees (external PDF file)

One potential problem with planting larger trees too close to buildings that may increase over time with climate change and drier summers is the drying out of the surrounding soil due to the large amount of water the tree will absorb, so think about the long-term in considering appropriate distances.

Detailed guidance on the height and spread of individual varieties of garden trees can be found on the Royal Horticultural Society (RHS) website and in Alan Mitchell and Allen Coomes book The Garden Tree: An Illustrated Guide to Choosing, Planting and Caring for 500 Garden Trees.

Visual Appearance

Both of the above sources provide illustrations of the visual appearance of numerous potential trees which might be considered for gardens. Relevant factors include whether it is evergreen or deciduous, whether it has attractive flowers in the Spring and attractive berries or other fruit later in the year, and whether it has attractive bark.

Environmental Impact

Trees such as apple, crab apple, damson, hawthorn, winter-flowering cherry and wild cherry provide important sources of food for bees and other pollinators (please see the UrbanBees website).

Maintenance Needs

The maintenance needs of trees include raking up leaves, which has the advantage of providing potential over-wintering homes for hedgehogs and numerous insect species and leaf-mould for garden soil enrichment. Planting trees too close to a pond, however, will result in fallen leaves rotting in the pond, a consideration that reinforces the desirability of drawing up a good scale plan of the garden to help identify where trees might suitably be planted in relation to the other garden features and buildings. All trees may need careful pruning, fruit trees in particular and the picking of fruit may be difficult if the wrong root stock is chosen for the tree. Detailed advice on the choice of suitable rootstock for different fruit trees to ensure a more manageable fruit tree height can be found on the RHS website.

Finally, consideration needs to be given to whether there are better alternatives to a tree in a particular site. There is, for example, a great range of flowering shrubs available which can provide colourful displays of flowers and fruit during the year, as well as the environmental benefits of providing valuable fruit and nesting sites for birds and pollinators. The BuzzAboutBees website, for instance, contains several recommendations of such flowering shrubs that will help our threatened bee population.

Information

The Parish Council is providing this new page for residents to highlight which trees are within the village conservation area, which trees have tree preservation orders on them and, if you are thinking of planting, afew ideas for trees for small gardens.

We are indebted to volunteers from Friends of Hagg Wood and Dunnington Conservation Group for their help with this page.

Dunnington Tree Trail

The Dunnington Tree Trail is a walk of some 21⁄2 miles around the village, describing trees of age, interest and beauty.

15 trees, most of which are native to Britain, are picked out to show something of their history, mythology and uses.

Wildflowers in your garden

We hope residents are enjoying the new wild flower beds opposite the play park and congratulate all of you who are growing wild flowers in your gardens.

Thanks to everyone for the photos of your patch – please keep sending them in or tell us where you are and we’ll take a photo for our wild flower gallery.

We noticed that some residents took part in Plantlife’s “NoMowMay” which encourages people to leave part or all of their grass for wildlife. If a lawn has been regularly sprinkled with fertilisers and weed killers over the years the number of species that appear will be limited, but if you don’t use the ‘weed ‘n feed’ on parts of it then over several years, as the fertility of the soil declines, more species of plant will emerge, along with increasing numbers of insects. In smaller plots it is probably advisable to control some of the more dominant species such as nettle, thistle or the native hogweed to give more delicate plants the chance to survive. These ‘undesirables’ can simply be pulled up at an early stage. If you are worried that this might make your garden look neglected, trimming the edge of the lawn and cutting paths through the grass or simply having a patch in one area will help to make the plot look managed. Soon you will be able to enjoy seeing birds such as blackbirds and sparrows foraging in the longer grass, while goldfinches will pull apart the seed heads of some of the grasses and flower species

Or you might prefer to plant your wildflowers or other species beneficial to pollinators in flower beds, pots or window boxes, also providing benefits to wildlife. Pots of wild flowers on paving slabs or on gravel paths will also attract bees and other insects and will be a cheery sight for residents on their walks round the village.

With the effects of climate change becoming more evident, whether it be record temperatures, wildfires or floods, it is more important than ever that we all take steps to try to reduce the impact on wildlife. The Department for Environment, Food and Rural Affairs (Defra) are now encouraging people to leave some of their garden in a less managed state. Increasing numbers of local councils are reducing the cutting of verges to help wildlife. If we all take some action, we will be helping to preserve the sight and sound of insects and the species that depend on them for future generations.

It’s easier than you think – here’s a simple project. Sprinkle wild flower seeds in a seed tray and keep watering. Soon you will have a lot of plants but wait until the growth is quite thick and resembles a turf of grass. Lift the whole lot out carefully and plant as one or two pieces of turf in your new wild flower bed.

For those of you who want to do it properly, here are some helpful sites.
