I repotted a Larch this spring (end of March, with buds just opening). Since then it really hasn't elongated at all. I was looking at Ryan Neal's "Larch Pruning" video which was filmed on 6/1/18 and his larch has LOOONG fronds. Mine are still just opened bundles of needles. Is this normal for Larch after repotting? It's a new species for me. I'm a couple hours outside of Seattle (on the wet side). It is potted in Acadama/Pumice/Lava, 1/3 each, and otherwise seems super healthy.
