"Mediterranean" and Other Tree's Winter Hardiness

[hemmy]

Well the young cork and live oaks are waking up.

Any advice on cork oak repots in the(se) climates? Bottom heat?

For completeness, I repotted the coast live oak saplings too late and too hard on the roots. The sprouts withered, there was stem dieback, and lost one completely. Another larger one with a more intact rootball survived. In my old climate, I don’t think these would have skipped a beat. But back under the T5s they struggled after the repots. The one that survived with a larger rootball was also under the LED. I’m not sure if that was a factor.

The larger one from the previous post is much healthier after strong summer growth with pruning and partial defoliation to replace the damaged leaves from last summer’s overwatering/fungus. I will try a repot to a bonsai training container this early Spring.

Should it go on a heat mat? Garage air temps will be 45-65F. It could go in the tropical tent, but I think 65-85F with 50% might be too much?

Crap, I jinxed it. I should have been watering instead of posting. I must have missed it and it went crispy on the ends. It will probably survive with dieback. Doh!
