Our speaker for our August meeting was Mike Abel on the topic of Growing Soft Fruit. Mike
had been a horticulturalist and taught Soft Fruit growing at college during his career.
Mike explained that all soft fruit is self-fertile meaning it doesn’t need another variety of fruit
to cross pollinate unlike for example apples. But the flowers will still need to be pollinated if it
is to produce fruit. As we have heard from several of our speakers, bumblebees rather than
honeybees are actually the best pollinators for a number of reasons. Their large fluffy bodies
catch a lot of pollen, they fly in colder weather meaning they are out earlier and later in the
day and they will even fly when the weather is wet. They are also willing to pollinate in
polytunnels. So, bumble bees are an important resource.
Soft fruit includes things like strawberries, raspberries, blackberries, blueberries,
gooseberries, and currants. They are propagated from plants (e.g. cuttings or rootstock) not
from seeds. Some useful tips about the various fruits were:
· Strawberries can be summer fruiting where the crop comes just once each year, or
continuous, but you get less quantity – so maybe not enough to fill your bowl! They form
runners after fruiting and you should peg these down so they root and create new plants.
‘Malling Centenary’ is recommended for good flavour.
· In raspberries you can get summer fruiting or autumn fruiting. The advantage of autumn
fruiting varieties is they are more self-supporting and don’t need to be tied up. You cut them
to the ground once they have fruited and they will fruit on the new wood they grow next year.
Whereas with summer ones you only cut out the stems that produced fruit this year and any
new stems will produce next year’s fruit. ‘Malling Minerva’ is a good summer variety and
‘Polka’ a good autumn one. All raspberries are very thirsty and need good watering.
· Blackberries – prune out the old wood once it has fruited but leave the new branches for
next year.
· Blueberries need acid soil (Ericaceous compost) and preferably rainwater.
· Gooseberries fruit on the old wood. A major pest is the sawfly whose eggs hatch into a
small green caterpillar and eat all the leaves before you even notice them.
· Blackcurrants fruit best on new wood. It is recommended that you cut out one third of the
branches each year. Birds are the major pest eating all your currants.
Mike brought samples of the plants so that we could identify them, and also brought a
selection of things for sale including fly traps and honeycomb.
