Greenhouse Species

[MoGanic]

Hi everybody!

Setting up a greenhouse soon for a few figs, just wondering what else I can bung in there?

Will, for example, my maples or wisteria benefit from such a setting?

Thanks peoples!

Hi Mo,
I have not actually tried because I have the feeling that many species will end up with problems from humidity, etc (maples are more difficult in more tropical climates??). The figs can tolerate (benefit from) it because they are tropical/ subtropical rainforest species so adapted to high humidity and temp.
I keep newly potted cuttings of temperate species eg elms in the poly house for a week or 2 to re-establish working roots. They certainly grow well in that time but I have not tried leaving them in longer because I am worried about fungal issues, etc.
Most deciduous species need a dormant period so if they do ok you might be able to extend the season but will probably need to take them out for some dormancy over winter.

Hmm perhaps an experimental group of trees is in order! Once it's finished setting up I'll go for it. I'm sure I have some young seedlings laying around!

Thanks mate, appreciate it.

MoGanic,
What is the most common deciduous tree used in bonsai in the Western hemisphere, also what is the most common conifer species in the West? There's a couple to go along with the figs. Think evergreen broadleaf flowering Native that makes good hedges and grows well North of Brisbane and in Melbourne, there is dozens of cultivars of these to play with.

Greenhouse ventilation is crucial for both airflow and temperature regulation. Incorporate ventilation into your 'house or don't bother. Many fungal issues can be overcome by more sunlight, limiting foliar watering and soil drainage, that rule applies to bonsai outside in a lot of circumstances which a lot of people still don't get.

Cheers,

Also, how big is your greenhouse?

Hey Mojo,

The greenhouse I'm putting up has two spaces in the roof for ventilation. In addition to this, I will have a small airflow heater at the bottom.

This might work well in terms of heat and ventilation, but I was wondering whether this would reduce humidity also?

Do you know of any set ups that will provide for better ventilation?

Thanks for the help mate, much appreciated.

EDIT** your post just came through - its 215 X 143 X H195CM

Just finished my greenhouse off, noticed it doesn't have the ventilation I thought it would.. given that I am going to be walking in and out would this be enough?? Can't wait to fill it with figs!
