1. One of my tree's had something on the bottom of their leafs. It almost
looks like grains of sugar. Have never seen anything like this
before. Any idea?

2. For the first time, I have an azalea. I normally put all of my trees on
my unheated closed in porch. I have been told that the azalea is going to
need sun all winter. So should I attempt to bury the pot and leave it out
doors in the sun? or can I put in on the front porch with the rest of my
trees. There is some sun light that does come in so it is not completely
dark. So far this has been a warm winter and I am just how putting them up
for the rest of the winter.

What tree? But I probably wouldn't worry. Most likely it is
just the tree ridding itself of excess chemicals -- either from
the water, or from left-over fertilizer in the soil. The
chemicals are precipitated from the stoma on the underside of the
leaves..

Azalea should do OK outside in most of zone 7, though you may
want to bring them into the porch for protection when
temperatures get into the low 20s and below. Then, put them
outside again when it "warms" up.

believe it is warm until temperatures reach the mid 60s.

One of my trees had something on the bottom of its leaves. It almost looks
like grains of sugar.

What kind of a tree? This is important. Do you see any damage or mottling on
the tops of the leaves? Is there anything that looks like a spider web or
cobweb?

It is a Meyer Lemon tree. I don't see anything but what appears to be
grains of sugar on the underneath side of the leaves. It is in need of a
lot more leaves in my opinion but I don't see the tree pushing any. It just
finished blooming. It is currently indoor under lights. It was outside
all summer and most of the fall. We have had a very mild winter, here is
Memphis Thanks for the reply.

Whatever it is I would wipe it off. My guess would be insect eggs
(moth or butterfly) trying to overwinter.

Hmmmm. Is it every leaf? Do the number of "grains" vary from leaf to leaf? Most citruses have smooth undersides to the leaves. Granular clumps could be insect eggs or signs of oedema (but this is a condition of indoor plants, and you say your tree was o
utside). Can you wipe them off? If you can, do so, and watch the tree carefully for a few weeks. If you can't... well, take the plant to your county cooperative extension agent if it worries you. As long as the plant looks healthy, there's probably no
thing to worry about.

Nina.
