[IBC] cold house?
 

Shireen,

a cold house is a greenhouse where you keep the temperature just above
freezing, say, at 3 to 5° C or so. The humidity is quite high ( I don't have
any gadget to measure it, so I can't give you the exact data, sorry). Before
I had the greenhouse in my garden, I wintered my dwarf pomegranates in a cold
(frost-free) garage. They don't mind standing in darkness, as they don't have
leaves in winter anyway.

Hope this helps

What's a cold house? It's recommended for some plants
like dwarf pomegranate for over-wintering. I live in
an apartment without a balcony so it's probably not
possible to build one. But if anyone on the list winters
their plants in a "cold house", I'd like to learn more
about the conditions (light, temperature, etc..)

Thanks,
shireen

Shireen:

Simply do the following to winter your hardy trees on the balcony.

1. Acquire wooden boxes large enough to accommodate the size of your bonsai pots.

2. Place cedar mulch in the bottom of the box.

3. Water the root pads with landscape fabric.

4. Place the trees in the boxes.

5. Bury the pots with mulch up to the first branch.

Be certain to insert chopsticks into the root pads. These can be used to monitor water consumption. Simply, remove the sticks on a daily basis and touch the portion that was in the soil. When it is almost dry, rewater. Importantly, when the trees freez
e, do not water.

Lastly, construct a wind breaker so that your trees do not get freeze dried by the cold winds of winter. Burlap can be secured to adjoining structures on the balcony and meet this shielding requirement.

Cordially,

Michael Persiano
