Anyone have any idea what is causing this? I’ve looked it up and found that at least for younger saplings. Some Browning can be normal in early spring, but none of the images had nearly this much Brown. There is barely any green left among the needles.
Do you know if redwood sapplings can survive in a low light environment like a garage over winter? What would be my best bet of getting one to make it?
Your best bet is to transplant it correctly in the ground this spring and let the plant get established this summer. Plants in pots are exposed much to more extreme temperature changes than if they are in the ground.
You can also cover them with some straw if the weather looks like it’s going for a sudden deep freeze and the trees are not covered in snow.
In general what is the best way to over-winter plants without planting them in the ground? Do you know? (I probably will move at some point and would like to take this with me so planting it isn’t my favorite option.)
