Yew Hedge Restoration

Removing Vertical Growth When Restoring Yew Hedges

I’ve been working on restoring the shape to a yew hedge this week so thought it would be a good opportunity to show the importance of cutting out vertical growth. This technique applies to restoring both yew hedges and yew topiary. If a yew has been left untrimmed, or has been badly clipped in the past, then thick, long stems can start to grow up on the outside of the hedge. These will thicken over time, causing the hedge to bulge and sag. Ignoring these stems and running the hedge trimmer or shears up over this vertical growth can create…

Managing Box Blight Outbreaks with a Fungicide

Autumn this year has been very wet and warm here in the UK. These are perfect conditions for fungal growth and outbreaks of box blight have been very common. Outbreaks can occur on the top or sides of the box and are identifiable by the browning and blackening of the foliage. These outbreaks occur almost overnight. The damage caused can be minimised if treated early so best to check box plants regularly. I spray a fungicide on to an affected area as soon as I see the first signs of a box blight outbreak. Hopefully this will slow the spread…

Red Ants Damaging Box Hedging

I have another pest to add to the growing list of threats to a box plant’s health and well-being. This one is the red ant (Myrmica rubra). At a place where I work there had been a lot of head scratching trying to discover the reason why the leaves of single box plants were starting to yellow in a healthy, established box hedge. If it was nutrient deficiency or lack of watering then you would expect to see other box plants in the hedge displaying the same symptoms. The answer was explained by small mounds of loose, fine textured soil…

Mysterious Brown Circles Appearing on Box Hedging

I wanted to share with you a problem someone was having with their box hedging that surrounds a lawn area. Brown circular patches were appearing on the grass side of the hedge and were all at roughly the same height. The owner’s Labrador was being accused of causing the damage so I was pleased to be able to exonerate the dog of all blame. The problem is a result of the hot exhaust on a lawnmower. This is not normally an issue if the gardener keeps moving along the hedge when cutting the grass. The damage is done when the…

Adult Mussel Scale on Box

Mussel Scale on Box

Mussel scale is a small insect that attaches itself to the stems of a box plant and sucks the sap. This can cause the foliage to discolour, turning yellow and orange. If the scale are left untreated the box may start to lose leaves and will have poor growth in the Spring. Have a close look at the stems of the box to see the adult mussel scales. The insect is tiny, only about 3mm long and is protected under a shell or scale that resembles the shape of the mussel mollusc. Treatment with an insecticide spray can be difficult…
