Griselinia Hedging Information
Griselinia Or New Zealand Broadleaf
These are upright evergreen shrubs that have simple, oval glossy green leaves and yellowish green flowers. On the female plants they have very small purple fruits when they are grown on mass.
They are ideal for seaside gardens as they don't enjoy hard frosts. If you do want to plant them North of Birmingham we do suggest they go in a sheltered site, urban gardens are usually much warmer so they are normally fine.The foliage tips can go black in a cold winter so we suggest feeding them with sulphate of potash in Autumn to toughen the stems against frost damage.
There are are couple of varities that we tend to grow,
Griselinia Green Horizon which is a newer variety that is hardier in the colder locations. They have the luxuriant glossy green foliage
They don't need much pruning just once a year around late spring to early summer and then just any regular pruning of untidy branches throughout the year.
Really cold areas.
All you need is a multi purpose granula feed such as chicken pellets or blood fish and bone. This can be done when they start to grow and again in the Summer. You can normally see when the plants are hungry as the colour would start to fade and not the glossy green they are usually.
