Caring for your Outdoor Bonsai.
This group of bonsai trees we categorise as 'outdoor bonsai' are temperate climate trees.These grow in Ireland, and northern Europe, so they more familiar to us than the tropical varieties.They should be kept outdoors,their normal habitat, for most of the year as they need to experience the fluctuation in temperature throughout the seasons..
Outdoors in an sheltered area, patios, small yards or gardens ideal.Some, like the evergreen varieties are suitable for balconies, once they are protected from strong winds. Some varieties prefer shade, others good sun. Certain species need some frost protection in winter. Check below in the' notes on popular varieties' section.Can be brought indoors for short periods especially in Summer, but abrupt changes from heat to cold can damage your bonsai.
Use rain water when possible, soaking your tree with a fine hose until you see water coming out of the drainage holes. Bonsai trees may need watering daily in summer.Even in wet, cold weather your tree will need to be watched, as cold winds can cause drying out,.
But never let your tree dry out completely.
The size, shape and health of your bonsai tree is created and maintained by regular pruning. Allow broad leafed trees to develop 3 to 4 sets of new leaves before pruning back to the first set of leaves at the top of the tree, and second or third at the sides. Remove any new shoots growing at the base of the trunk, cutting across the trunk, or in positions that take away from the appearance of the tree. Thin out regularly. This should be done between May and September.
Repotting Your Bonsai
Re-pot your bonsai as soon as the roots fill the pot. This can be yearly for trees up to 10 years of age, or every two to three years, as the tree gets older. The ideal time is in early spring, although most indoor bonsai can generally be done at any time of the year. Roots must be trimmed back by roughly a quarter, and fresh bonsai compost must be used. Use a free draining compost specifically designed for outdoor bonsai

You can change the shape of your tree by wiring. Special aluminium wire is wrapped around the trunk or branch of the tree and used as a brace so the position of the trunk, or branch can be adjust. The wire is removed several months later. This requires some skill, so proceed with caution.
