Best Bonsai Winter Care Supplies
Updated How we research
Winter damage to a potted tree has little to do with whether the species is hardy in the ground. A shallow pot holds a root ball a few centimetres thick that freezes solid within an hour and thaws again every sunny afternoon, and it is that cycling, plus dry wind on foliage the roots cannot resupply, that does the killing. The shopping list therefore follows the routes water is lost. Frost cloth is rated by weight per square yard, and the one and a half to two and a half ounce grades pass light and rain while lifting the air a few degrees, which is what a dormant tree wants rather than a sealed plastic sheet. A narrow roll of burlap goes around trunks and pots to break wind and keep bark from splitting on freeze and thaw days. An anti desiccant spray coats evergreen foliage and slows transpiration for several weeks, which matters most for broadleaf evergreens still losing water while the soil is frozen. A waterproof propagation mat under a tray keeps a root ball just above freezing in an unheated space. Trees brought inside have the opposite problem, because heated rooms are dry and dark, so a full spectrum lamp on an eight to twelve hour timer restores the day length, a pebble tray lifts local humidity, and a gauge on the bench shows whether the air sits at forty percent or twenty.
