Best Humidity Trays for Bonsai
Updated How we research
Humidity trays raise moisture in the small pocket of air directly around a tree, which matters most for tropicals in heated rooms through winter. They are not a substitute for a bright window or correct watering, and the effect drops off quickly as you move away from the pot. What varies is surface area, tray depth, whether pebbles are included, and whether the pot sits above the waterline or ends up standing in it. We weighed footprint and depth, since a wide tray holds far more evaporating surface than a deep narrow one. Pebble trays suit ficus, fukien tea and other tropicals on a windowsill. Larger flat trays suit growers with several small trees grouped together. Metal and slate trays suit anyone who wants the tray to disappear visually. Keep the pot base above standing water, or you trade humidity for waterlogged roots.

Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 8/10

- + Two trays in the pack, enough to cover two big trees or two groups of small mame and shohin pots
- + Listing describes the plastic as thick, corrosion resistant and sturdy enough to carry pots on
- - No pebbles included, and a tray this size needs a good amount of gravel to fill properly
- - Takes up a lot of shelf space and is sold only as a pair, which is more than one small tree needs

Fit for the job 8/10 · Features and specs 7/10 · Build and materials 8/10 · Value 7/10
