Sizes poorly done, insects, weather, diseases, soil deficiencies... There are solutions to restore your health and beauty hedges!
A hedge is more beautiful if it is regularly maintained.
- But the two or three sizes needed per year are all risks of error that can lead to malformations.
- Very often, wire brushcutters damage the base of plants.
- The forgotten threads on which the twigs are trellised also cause, with the growth of the plants, strangulations which lead to chancres or irremediable wounds.
Insects and bad seasons
- Insects also cause considerable damage. This is the case of mites (or "red spiders") that cause the death of certain conifers.
- Finally, the snow or the storm can sometimes deform or break branches on certain species.
- As for the salt spread on the roadway in the event of frost, it proves to be formidable for the good health of hedges in urban environments.
Hedge maintenance rules
Fortunately, it is possible to repair different damage thanks to grinding sizes.
If you have allowed some hedges to grow (laurel-cherry, bay laurel, boxwood, lariata, etc.), their size requires significant mechanical means.
Free hedgerows often become an entanglement of twigs, in which the most vigorous species suffocate the weakest. For deciduous hedges, prune in winter.
For persistent hedges, operate in April. Fold down the branches by at least 50%, even flush with the main stem. To avoid a severe shock, proceed for two years, cutting one face first and then the next the next year. As the hedge will suffer, be sure to water and mulch the soil to prevent drought.
Finally, to promote the growth of young shoots, bring natural fertilizers.

Hedges: adapted treatments
• The thuya or cypress of Leyland should not be cut to the wood. In case of restoration size, fold down making sure to keep buds to facilitate regrowth. On these species, it is often easier to remove the hedge in place and replant young plants.
• If it is an yew hedge, make a flared shape at the bottom that will be more wind resistant and allow the bottom leaves to receive light. To achieve this result, make a template with an adjustable arm that indicates the right angle (much like a giant compass).
• Plant hardy species that are adapted to the soil and climate of your garden and maintain a spacing between two plants that corresponds to plant growth.
• One of the recurring mistakes is to want to grow the hedge too quickly. Limit its height gradually, from 10 to 40 cm per year depending on the type of shrub composing the hedge.
