I'm reading that the Wurtz is a self pollinator.. not exactly sure how that works.

As far as overwintering.. is it necessary for the tree to go dormant for a while? Thanks for your help!

No. Avocados are sub tropical trees and they never go dormant. They love well drained soil and warm weather. They HATE wet feet (don't let them sit in water), and HATE freezes. They will die if you allow that. You will need to treat your avocado as a houseplant in winter.

Thank you, any thoughts about cross pollination vs self pollination? This stuff is way too confusing for me. Appreciate your help.

I don't have that variety. Mine do require cross pollination, but if your research states that Wurtz is self pollinating, then you don't need another variety. I have a Zutano seedling that has not yet fruited. It's in ground, 4-5 years old, and taller than me. Since seedlings often produce fruit unlike the parent, I purchased a Jan Boyce to graft on to it. Jan Boyce needs pollination. So does Kona Sharwil, and they will pollinate each other.

Part of me wants to see just what that seedling can do, but the smart part of me says, graft Jan Boyce onto it so you will know you have a delicious variety.

Enjoy your tree!

I feel like I'm learning so much here :) It is such a patience game with Avocados.. My poor tree is still in shock.. not dying (losing leaves), not growing (at least above surface) and its been over a month. I had the same Wurtz variety a few years back and left it out in the chill one single night and it was gone in the morning.. Charlotte is beautiful but it has a tad bit too much cold for Avocados.

Here is an update on my Dwarf Wurtz. Any thoughts comments on progress? I don't love how that lower branch hangs down with weight it is carrying. Should I address that? Also many of the leaves have holes, etc from local pests. Do I need to spray the tree or not worry about it?

Yep, looks good. Btw, avocados love having their own leaves as mulch. I see you have some leaves in the pot, that's good. Put them all in there as they fall.

Is it common for leaves to continue to fall? I have had quite a few shed this year.

Yes, Avocados drop a lot of leaves in late winter/early spring, just as the new leaves are starting to grow and they often shed for several weeks.

All trees shed old leaves at some point. Deciduous trees do it all at once, evergreen trees do it either all year long, or just as the new leaves emerge.

If it only sheds leaves and no new ones are growing, then you have some kind of problem. I see a lot of nice new growth on your tree so you should be fine.
