Evergreen bonsai do not shed their leaves in the fall, but as the name suggests, remain green all year round. They may be either broad-leaved or conifers.
Conifer Bonsai Tree Species

Some commonly-grown conifer bonsai tree species are:
- Bald cypress
- Buddhist pine (Podocarpus sp.)
- Hinoki cypress
- Japanese cedar
- Juniper (Juniperus sp.)
- Larch and Golden Larch
- Pines (Pinus sp.)
- Redwoods (Metasequoia sp. and Sequoia sp.)

Evergreen Bonsai Care
Generally, evergreens need less watering than deciduous trees, but should be watered all year round.
During summer, place your evergreen bonsai in a position of partial shade. Ideally you should place your tree off the ground to protect it from ground dwelling insects and from your pets.
Water moderately, leaving the soil to dry in between. Your bonsai will also benefit from being turned periodically.
Feed your evergreen bonsai from mid March to early September.
Conifer Bonsai Care
Conifer bonsai trees are winter hardy and need no special winter care—your conifer bonsai can simply be left outdoors.
Ideally, they should be placed in a position of full sun and protected from strong wind.
Repotting, pruning and wiring should be done in winter.
Broadleaf Evergreen Bonsai Care
Broadleaf evergreen bonsai are not generally as winter hardy as conifers.
Many varieties, however, such as Satsuki Azalea, Loropetelums and Gardenias, can be left outdoors during winter provided they are not exposed to severe frost.
You should move your bonsai temporarily to a cool, well lit interior, such as a greenhouse, porch or conservatory during especially cold winter spells.
