Pollination
Most cultivars are somewhat self fertile, but good bee activity has been shown to improve pollination, which results in larger and better shaped berries. Commercial growers sometimes place beehives within range of the fields to increase bee populations. This rarely occurs.
Forcing
The runners propagated for forcing are layered into 75 mm pots, filled with rich soil, and held firm by a piece of raffia, a peg or stone. If kept duly watered they will soon form independent plants. The earlier they are secured the better.
When firmly rooted they are removed and transferred into well-drained 150 mm pots, of strong well-enriched loam, the soil being rammed firmly into the pots, which are to be set in an open airy place. In severe frosts they should be covered with dry litter or bracken, but do not necessarily require to be placed under glass. They are moved into the forcing houses as required.
