Happy Easter to all.

Petals from the Past had them available at the store, did not see them online.  If you could call you migjht be able to order them that way and have it shipped.  They are on flying dragon which is a good cold hardy dwarfimg rootstock.  Like all satsumas, they have a weeping habit.  I also picked up a miyagawa and a China 9 at the same time there.

Looking for a source that can ship out of FL or that comes from outside of FL.

My young, first year in ground oro blanco grapefruit withstood 16 degrees (-8.89 degrees celcius) one night and 17 degrees (-8.33 celcius) the next night.  It lost all leaves and the new green growth it has looks fried, but the mature growth is still alive.

For a quick way to throw some protection on the stem above the graft line, i make at least a foot diameter circle around the trunk with cardboard and fill it with dirt as high as i can.  I then pack it so there is not a gap when the tree sways in the wind between the trunk and dirt.  It looks this far as most of my trees have pulled through with multiple nights around 20, one down to 16, and one to 17.  There is some damage but it does not appear to have killed any above the dirt.  A lemonquat looks to have taken significant damage.

I have heard that there are incompatibility issues with meiwa on carrizo and swingle:

Justfruitsandexotics have a few satsumas including xie shan.  Its in northern florida.

I have all arbequina.  They started off slow but are growing a lot faster now.  I have had a few olives here and there bit not enough for a harvest yet.  They dont seem to have issues with the cold at all.

That appears to be the asian citrus psyllid nymphs feeding on your tree.  The white strings is their excretement.  Do not let these remain on your tree as these spread citrus greening.

Leafminers come back every year here but dont become active until May or June.  All growth next year until the leafminers appear will not have the damage to the leaves (citrus leafminers for the most part only attack the new growth).  You can get soil drench pesticides to kill them or just let them be.

Those are citrus leafminers.  Nothing to worry about unless it is a young seedling.

Is there a specific type of mesh/screen that needs to be used to keep out the acp?  Additionally, if ants transport the acp, how could they be kept out froming coming underneath the screenhouse?

I am interested in the white pakistan mulberry.  Any opinions on it? And does anyone know of a source on it (I see justfruits but they haven't had them in stock in a while)?
