The Olive (Olea europaea) is an evergreen
tree or shrub native to the Mediterranean, Asia
and parts of Africa.
It
is short and squat and rarely exceeds 15 meters
in height. The silvery green leaves are oblong
in shape and the trunk is typically gnarled and
twisted.
The
Olive has been cultivated since ancient times
as a source of oil, fine wood, leaves and fruit
for consumption.
The
fruit is naturally bitter and must be fermented
or cured with lye or brine to make it palatable.
The trees we stock are capable of producing fruit
and often do, but fruit production can be erratic
and even mature trees seldom bear well two years
in succession.
Olives prefer a calcareous (limey) soil but will
grow well in any light soil however poor or dry.They
will even thrive in clay as long as
some gritty material can be incorporated and drainage
is adequate.
To ensure you give your olive tree the best possible
start in life, follow these basic instructions:
-
Site in the sunniest position possible, ideally
south or west facing and with some protection
from cold, drying winds.
-
Plant in free-draining soil and never allow
roots to become waterlogged.
-
Olives can grow successfully in containers for
many years. Use a mix of good quality multipurpose
compost mixed 50/50 with John Innes No.3 and
a few handfuls of grit to aid drainage. Never
over-pot your olive and always re-pot just to
a slightly larger pot than the one it is in.
Raise the pot slightly off the surface it is
sitting on so water can drain away freely.
-
Prune to maintain the required size and habit.
Prune lightly in mid-spring, more heavily in
early to mid summer. Never prune in autumn or
winter as the wounds need some heat to heal
over before the dormant winter period.
- Feed
with seaweed extract fortnightly between May
and September. Olives can tolerate fairly cold
winter temperatures, down to -7C in most cases,
without needing protection. If it is likely
that the temperature will drop below this level
for more than 24 hours it is best to wrap the
crown and trunk with several layers of horticultural
fleece to protect from frost.
Olives
in pots are always at risk of their roots freezing.This
could lead to the plant suffering from drought
through not being able to take up water or worse
still, the roots will be damaged which can result
in poor growth or death of the tree. In order
to prevent the
roots freezing, wrap several layers of bubble
plastic around the pot and secure with twine.
