Thanks for all you do Kendall! Often you ask the question during the live stream that I want to ask.
Keeping the stream real and personal is not an easy task. :heart_eyes:

Hi, I would like to know the best time to re-pot Spruce, I remember hearing that a great time is once the buds have opened and the new growth is pushing as the tree can then allocate the vascular resources to the roots. Or should this happen right as the buds swell? I am specifically talking about a Pungens now that was going to be a landscape tree and I thought, “no, you’re going to be a bonsai.”: )

Thanks

aha, I think I found a good source in the Live q&a links provided:
