How can I use a polytunnel to extend the bonsai growing season?
I'm looking to extend the growing season for my bonsai trees using a polytunnel, but I'm not sure how to effectively manage temperature and light to achieve this. I've grown bonsai for many years outdoors, but I've never had the opportunity to use a controlled environment. My concern is that while I want to extend the season, I also need to be cautious about overexposure to heat or light, which could stress my trees. What strategies or techniques do you recommend for maintaining a balance? Any specific adjustments to environmental controls during different times of the year would be greatly appreciated!
