This ancient, nearly
prehistoric tree should be named Ginkyo, which is the latin adoption
of the chinese word Yin-Kuo which means "silver apricot".
It has a pyramidal silhouette with a straight trunk which grows
aerial roots on the older exemplars. The ginkgo trees are perennial
showing the leafs a beautiful yellow color in autumn.
Needs much light, likes inclusive direct sun exposition. The younger exemplars should be placed
in mid-shadow during the hot summer because of their smaller pots.
Temperature and exposure:
Ginkgos are supposed to be sensible against freeze, my experience
is that ginkgos are very resistant trees, being there no difference
between very high and very low temperatures. My tree is outside the
whole year and the temperatures in Madrid are quite extreme.
Pruning and cleaning:
Pinch the new sprouts you don't want to let grow. Also pinch the new
sprouts at the extremes of the branches to help develop lower branches.
Remove some leafs leaving more or less 2 or 3 leafs per branch. Branches
should be pruned in spring when you repot the tree. Remove the branches
you don't like and cut the rest to 2/3 of it's length.
main form of the ginkgo trees is given by pruning, in the case of my
tree i had to wire the main trunk because it was totally straight and
didn't look natural at all. Be careful and protect the soft branches
ginkgo doesn't seem to need a lot of water, but i keep the soil humid.
Never water when the sun burns down on it, neither do it when very cold
temperatures are expected. Vaporize the trees several times a day.
Repotting / Soil:
Should be done between spring and summer every two or three years into
a bigger pot. Wait until the new sprouts are visible. Cut about 1/2
of the roots. The mixture I use is 1/3 compost, 1/3 humus and 1/3 sand.
I like the blue and black ceramic pots, normally circular.
Should be applied during the spring and autumn but not in summer. Never
use fertilizer after repotting, wait for about two months. I prefer
the solid type which dissolves itself when tree is watered.
are very very resistant against parasites, i have never had any parasites
on my tree.
