species bonsai require that they are housed indoors or in a heated greenhouse

from Autumn to Spring (the exact timing dependent on their exact frost-
hardiness).
However, all fully hardy bonsai are kept outside all year round with no
protection from the elements unless temperatures drop below -10ºC. Allowing
your frost hardy bonsai to be exposed to the seasons allows them to grow
naturally as they would in the ground and encourages much healthier and more
vigorous growth.

The ideal position for your bonsai is for them to be kept off the ground on
wooden benches or monkey poles, and each bonsai is placed in a position where
it receives the amount of sunlight needed for healthy growth.
As some bonsai such as Pines require at least 8 hours direct sunlight whilst
some bonsai such as Hawthorn or Japanese Maple will tolerate as little as 3
hours direct sunlight, careful observation of the light levels around the garden is
necessary. Similarly, consideration of the prevailing winds should be made.
Placing a bonsai in an area of the garden that is liable to be hit from the full force

strong winds could result in a favourite bonsai (and its pot) being discovered
lying in pieces on the ground after a night of heavy storms.
Other considerations for bonsai placement should include more domestic
concerns such as the security of prized specimens, footballs from neighbouring
properties and the local cat, squirrel, bird, rabbit and deer populations that can all
have a terrible habit of damaging bonsai!
