below this level will cause a gradual deterioration in health. Do not position

where the tree will be exposed to cold draughts as this can cause leafdrop
through stress. Encourage higher humidity levels with the use of a gravel tray
and never place above radiators which dramatically dry the surrounding air.
Temperature fluctuations should be kept to a minimum.
During the summer when night temperatures remain above around 12°C, try to
place Figs outside where there is increased light, better humidity and warm air
circulation to increase health and vigour levels. Most figs grow best in
temperatures between 15°C and 30°C. Temperatures above or below this will
slow growth; continual exposure will eventually lead to ill-health.
Feeding Feed only when showing active growth; do not feed during the winter if
growth stops or if the plant is showing signs of ill-health. Feed with high-
nitrogen or a balanced fertiliser fortnightly.
Repotting Repot in Spring every two years using basic soil mix.
Pruning Hard prune in Spring ideally though most figs will tolerate this year
round, trim new growth back to shape during the growing season. Figs bleed a
milky, white sap (latex) when pruned and this can be used to seal wounds by

dabbing with paper or a cloth. When pruning back smaller branches, leave a
short stub which will dry out over the following days, removal of this dry stub is
easy and leaves a far smaller scar in the bark.
Propagation Figs are very easily propagated from cuttings at any time of the
year and from airlayerings.
Pests and Diseases Scale insects and mites can be a problem. It should be noted
that Figs will not tolerate insecticides containing Malathion. Leaf loss is nearly
always due to stress caused by overwatering or incorrect placement though if
conditions are improved, Figs are able to leaf out within 3-6 weeks.
Styling All forms except Literati in all sizes.

Juniperus/Juniper Bonsai

Along with Pines and Japanese Maples, Junipers are one of the three most
frequently used genera for bonsai. Juniperus is a genus of 50+ species of
evergreen, coniferous shrubs from dry forests and hillsides throughout the world.
Junipers have foliage of two types, needle-like juvenile foliage and scale-like

adult foliage, species that exhibit predominantly one or the other are used for
bonsai cultivation. The range of colour of the foliage ranges from steely-blue-
greens to light greens occasionally with silver or gold hues.
Most of the classic Juniper bonsai in Japan have been collected as yamadori
