High Health Certified Stock; quality roots, tips and long canes
We at Berryworld Varieties only use plant material that comes from High Health Certified Stock to give our growers confidence in the plant material they are purchasing.
Root is produced from certified plant material that has been trueness to type checked so is free from pests and disease. Field grown substrate is washed prior to dispatch, and substrate grown root can be washed on request. There are two main types of root available, and can be used to establish cane for fruit production.
A tip is taken in the same process used to produce a module plant. This module plant is then planted into a 2 litre pot and allowed to grow on into a long cane plant which is between 1.5 – 2.0 metres tall, and the aim is to have 20-30 viable buds.
The long canes are then held over winter in order to accumulate chill units, before being dispatched to growers. Long cane plants are graded before dispatch to ensure uniformity of plant material, thus making management of the crop simpler.
Cane height can vary because the distance between the buds known as the internode spacing also varies from plant to plant though this variation is kept to a minimum by keeping conditions in the glasshouse as constant as possible.
Long cane can be manipulated to produce fruit when desired so offers greater flexibility e.g. light and heat can be used in glasshouses to produce an early crop, or planted into polytunnels on different dates to spread the production of fruit.
It takes 14 months to produce a long cane plant so orders for long cane have to be made in advance.
Certified root is placed onto heated beds which produces shoots that are cut from the root and planted into a tray of pots where it is allowed to develop a root system. This will develop into an individual plant that has come from plant stock that has been certified, and trueness to type checked, but is supplied at Plant Passport Health status.
Planted in March, these will produce an even establishment of grower produced primocane, with fruit being produced in late summer/early autumn.
