Two Litre Potted Plants
Blackberries are slow to establish and realise their yield potential. Under good establishment conditions a 2 litre potted plant produces up to 25% of its potential in the second summer after planting and 75% the following year. A 9cm plant will be less productive during its first three seasons.
Thornfree varieties can be trained and picked much more cost effectively than thorny varieties and, with the exception of Karaka Black, should be chosen in preference for any large scale planting.
