Other ongoing J-WAFS projects include work to engineer cereal grains that can fix atmospheric nitrogen in the same way that legumes do, in the hope of realising self-fertilising
high-yield producers in varied regions across the globe, and reducing the negative effects of the use of chemical fertilisers.
If there aren't any local trees to cross-pollinate with yours, you do need a self-fertilising
one, such as Laxton's Superb, a century-old variety.
IF you only have space for one tree choose a self-fertilising
variety, which can produce fruit without pollination by another tree.
A good, self-fertilising
pear is Conference, but apples require two different varieties for pollination.
Q I BOUGHT a self-fertilising
Stella cherry tree five years ago.
