When to unwrap fleece?

[Aparecium]

I planted two little pittosporums in 2022. Winter that year killed one and half-did for the other, so last winter I mader a little bamboo and fleece tipi over the survivor. (Of course last winter it didn't snow!)

When should I uncover it?

Depends where you live, normally after date of last frost. There is a site online. I'm in the SE UK corner,a few minutes from the sea,south facing,so I don't have to fleece.

Also SE. Thames valley. And a sheltered corner of the garden. I did not expect a pittosporum to need protection.

Winter 22/3 was really cold with long, hard frosts down to below -10, and pittosporums would have really struggled with that. In a normal winter, they should be okay in the southern half of the UK.

I had a lovely one in my garden which lasted for 15+ years, and it was a particularly cold winter that killed it.

I'd uncover it now, and only cover it back up if we are likely to get a frost below -2 or so. They are evergreen, and during the day it is now warm enough for it to photosynthesise.
