I was recently gifted a bonsai growing kit as a birthday present and got a couple of seedlings from the kit. Image below are some of my Pinus Aristata and Pinus Thunbergii all between 2" - 4" in height. (Not pictured: Picea Mariana)
Before I get to my questions I want to mention that after my initial excitement of getting my first seeds to germinate, I scoured the internet for ways I can ensure my seedlings stay healthy. In doing so, I’ve come face to face with my naivete and have learned that:
- seed starting bonsais is a pretty bad idea
- pinus aristata are not meant to be grown in my zone (PNW, 8b)
- I sowed these seeds pretty late in the Spring (May 9th)
With that said, I am unreasonably attached to these little guys due to my uncanny ability to anthropomorphize anything and everything. I want to do my best to keep these little guys alive.
Here are my questions:
Can I keep my seedlings indoors and under grow light until spring next year, moving them into a garage that stays between 25-45 degrees during the winter? According to this similar post last year, this could be okay. I am concerned that these seedlings will not have enough time to grow and establish themselves to face even a mild PNW winter. Temperatures don’t drop very low, but I’m concerned about what the amount of rain we get here during the winter will do to the pines.
Would it be better to let them outdoors in the summer/fall and take them in the garage during the winter? I’m aware that bristlecones do not like lots of moisture and hot weather; fall is very wet here and lately we have been getting around a max summer temp of 95 degrees.
Along those lines, is there even any hope to keep a bristlecone alive here for any significant amount of time in 8b?
Responses to my questions, or any general advice to keep these seedlings healthy is much appreciated.
