Welcome to the third issue of our apple club
newsletter. We hope that you enjoy it.
The
fruit we grow
Present
day strawberries are all descended from one common ancestor of
relatively recent origin. It all began with the exploration of
the Americas by Europeans in the 1500's. The North American
native strawberry (Virginia strawberry) was the first to be
discovered, and it was imported into Europe in the late
sixteenth century. It was a popular arrival because although its
flavour was only reasonable, it carried much larger fruits than
the native small- fruited species of Europe.
Then
in 1714, another strawberry was brought to Europe; this time
from Chile by the French explorer Frezier. Although it bore few
enough fruits, the fashion of the time was to plant that which
was new, and so the Chilean strawberry was planted in the
fashionable gardens of Paris.
While
traditionally these two strawberries had never met, inhabiting
different sides of the American continent, when brought together
to the gardens of Europe, a hybridisation became inevitable.
And
so from these crosses of the 1700's came what we now call the
cultivated strawberry. Inheriting the properties of both its
parents; size from Virginia and flavour from Chile, the
wonderful strawberries of today arrived.
Fungi are at war in our trees
Does your tree have it; now here's how you tell -
the
leaves go pure silver and you know its not well.
There's
full scale warfare going on in the heart of our plum orchard. It
all began with an attack on the plum trees by a disease called
Silver Leaf. This fungus enters the tree, and feeds happily
within its transport system. However, the effect on the tree is
not so happy. Slowly but surely its system gets blocked as the
fungus consumes the heart-wood of the tree. This was a battle
which no tree would win.
Just
when we were beginning to despair, we heard of another fungus
that would take care of our trees. Available from Sweden and
called Trichoderma, this is a beneficial fungus which attacks
the silver leaf disease. An ally for the plum tree.
This
fungus is natural in trees, and once within them, begins to
search for its favourite food - other fungi like the one causing
silver leaf disease.
We
contacted Sweden, and were sent some tablets containing the
fungus. We were told to drill holes in the infected trees, and
insert some tablets. The helpful fungus would enter the tree and
protect it from silver leaf disease.
We
did as were told and waited for an effect. The fungi did battle
in the heart of the trees. What, we were wondering, would be the
outcome? Then slowly the trees began to recover. Now almost all
are healthy again. With not a chemical in sight, and the disease
gone for good, nature's wonders never cease.
