Known as ‘May blossom’ because historically it has flowered in May, it’s also called the ‘bread and cheese tree’ because of its ‘edible’ leaves, and was named ‘hagthorn’ in Anglo-Saxon. And with ‘haga’ meaning hedge, it is not surprising that we find the hawthorn tree as part of many hedgerows across the country as well as growing as a standalone tree in shrubland. The hawthorn can grow, in full maturity, to heights of up to 15 meters and is identified by its entwined brown-grey bark, branches fortified by thorns and lobbed leaves. The hawthorn flowers between the months of April and May and produces deep red berries or ‘haws’.

In your garden
The hawthorn has been used over the centuries as a hedging plant and holds great potential for wildlife in your garden.
 
The tree can provide nourishment for a variety of insects, including caterpillars, moths and bees, which will all happily gorge themselves on the plant, and many birds enjoy the antioxidant rich berries and the shelter of the tree’s thorny branches, so don’t be surprised if your garden gains a few extra residents once or twice a year. The hawthorn will grow in most soils, but for it to reach its full blossoming potential you’ll want to place it in direct sunlight.
 
Threats your hawthorn may face
Hawthorn trees are susceptible to aphid attack and gall mites, so you may want to consider companion planting – planting another species of tree close by in order to protect one another from pests like these – the ecologically friendly way of lessening pest numbers. In addition, the bacterial disease fireblight may also cause a few issues unless you regularly check for infected branches and remove them to prevent it spreading.
 
A few things you may not know about your hawthorn tree:

  • Hermaphrodite – The flowers in the tree are both male and female and are highly scented (some think they smell nice, others less so).
  • May Tree – This is the only tree to be named after its flowering period, however, with a changing climate we have seen the hawthorn bloom earlier and earlier in the year, often now in April.
  • More than firewood – Even though hawthorn timber is renowned for its high burning temperature the hard timber is also used for turnery (making objects on a lathe) and engraving.
  • Edible leaves – Another name the tree has gone by is the ‘bread and cheese tree’! This is due to the fact the young leaves, flowers and flower buds are all edible and can be added to your green salad.
  • Bringer of Death – In medieval Britain, it was said the blossom of the hawthorn smelled of the Great Plague! Superstition insisted that bringing it into your home would cause death and disease. However, botanists later discovered a chemical in the blossoms that is residual within decaying animal tissue, so perhaps it was the smell that fuelled their worries!

If you’re thinking of extending your home, whether up or out, you may be tempted to make your first call to a local builder or a creative architect to instruct them to get the ball rolling, but STOP, not so fast. If you have trees anywhere near the rear of your house, then there’s another professional that you should call in first or you run the risk of wasting thousands of pounds that could have otherwise been spent making your extension everything you’ve dreamed it could be.

The weather this year has been crazy. First, storms smashed into us with winds gusting up to 90mph, then the cold seemed to linger for months longer than usual, and finally in May we had the hottest bank holiday on record as we all wilted in the blazing sunshine. Such weather can weaken our trees or even be instrumental in bringing them down. Therefore, this Extreme Weather Series of ours aims to help you to prevent the damage weather can do to your trees, or that your trees can do to your property (or someone else’s) in the worst-case scenario.

As we have seen in previous ‘sick tree’ series blogs, moths really can be a nuisance to our tree population – in the case of the oak processionary moth (OPM), they can even be lethal. While nowhere near as damaging to a tree’s health, the horse chestnut leaf-miner can significantly change the appearance of the horse chestnut trees they feed on, and can cause great concern if you see this happening to the trees in your garden. This article should help you to identify this little blighter so you can relax in the knowledge that while the damage they cause may not look great, the harm they do will be minimal.
