Biodegradable Hedge Plant Guards
Why Use Plant Guards?
In the past we've reluctantly had to recommend photo-degradable plastic spiral guards for new plants, particularly hedge whips (up to 90cm high). "Reluctantly" as they only partly break down in the sun if not removed, and leave tiny bits of plastic behind. These become absorbed in the soil.
New plants do need guarding. Rabbits, hares and voles are a real nuisance to new planting. Strimming can also damage new plants, particularly in hedges where it's used to control weeds and grass. Secured by canes, these plastic spirals will also support new plants and reduce wind rock.
Biodegradable Plant Guards
We have trialled various biodegradable guards in the past, and this is the first one we've felt confident about. The guards are made of something called Polylactide (PLA), which is a polyester made from renewable biomass - plants like corn and sugar beet.
The spirals are translucent, allowing some light in. They have holes for ventilation, and hold their shape well for long enough that the plant inside can establish properly - i.e. for several years. They're robust and have the right springiness to fit and remain in place.
They're currently more expensive than the old guards, but we hope prices will fall as demand increases.
We supply the guards with canes.
