You have worms. Those little cocoons are eggs. If you uncurl the leaves you will see little tiny white worms. They will eventually kill all your leaves. You need to buy a systemic. I bought Bayer but it was kind of expensive about 26.00 but it is concentrated and I still have enough for another year or so. Any systemic will do. It comes up through the trunk and into the leaves killing all the worms. Following the directions you mix it in a bucket with water and pour it around the tree staying the appropriate distance from the trunk. You usually only have to apply it once a year. I did this 2 yrs and this year I don't have any worms. A systemic is time released and worked great for me.

Hello again: Similarly, birch tree problems (i.e. leaf miners) can be "headed off at the pass" by painting a band of a systemic insecticide approximately chest height on the tree trunk each year, early spring. Just go to your friendly garden store, tell them you need a systemic for birch leaf bugs and they will sell you the right stuff, complete with instructions.

I have a huge infestation of aphids on my trees which are 30-40 tall. Any recommendations on how to control them. they are causing considerable damage.

I bought my home a few yrs. ago and I have lots of green leaf locust trees with pods. I also live in southwest Ks. and we have been in a severe drought. My question is my leaves are turning yellow. Can you help me save my trees.

I have a huge Sunburst Locust on our front lawn about 30 feet from our foundation and we haven't had any problems. The Locusts do get aphids in the spring and summer, however they do disappear and new growth happens. These trees are great shade trees. The leaves are a beautiful golden colour in the spring and are the last leaves to fall in the autumn. They look almost gothic during the winter months with their zig zagging branches. These trees have the hardest wood and are tolerant to cold and drought. If you are having reservations about getting one don't. They are one great tree. Ours is thornless and does not get pods ever.

My sunburst locust tree is about 7 yrs old and is getting a sort of light green "fungus" growing in patches all over the bark and branches? Does anyone know what this is and if there is a cure? Thank you! I live in the Thumb area of Michigan.

my sunburst is thin with dead branches, does it need food?

My sunburst locust is 35 years old and huge. this year, most of the leaves have fallen off of the lower branches in the last 2 weeks. there is a lot of dead looking wood on the tree. what to do?

I have owned my home for 10 years now and have 2 Sunburst Locust trees in my front yard, facing East. Enjoy wonderful shade But This year it looks like the one on the South is dying! Most of the bottom branches leaves have turned brown and falling off. I am just sick and know not what to do. I live in southern Minnesota. I don't know if I should call a tree Doctor ( don't know if one exists in this area) Help please.
