I have a white, sticky crystal on the eucalyptus trees around my place. The leaves are starting to fall off more than I have ever noticed before. Is there a treatment for this problem? I am in the foothills of the San Joaquin Valley in California.

3. Eucalyptus Trees/Leaves Shedding

Asked by Anonymous - July 26, 2011

We have recently moved into a house with two Eucalyptus trees in the garden, well established and about 20-30 feet tall. However, they are shedding leaves all the time and destroying the look of the newly landscaped appearance of our garden. We have a clay type soil. Is this normal, and will they finally stop shedding their leaves in a particular month? Please advise as I really cannot see how we are going to cope with clearing this up all our lives as we get older.

4. Tree Pruning

Asked by Anonymous - July 26, 2011

I have a fairly large silver dollar gum that is too large for the site. I want to reduce its height by half but if I do, I will cut away most of the leaves. Will this variety produce new leaves, and if so, when should I do the severe pruning?

5. Eucalyptus Tree Flowers

Asked by Anonymous - August 5, 2011

I have lived in my house for 4 years. I have never seen any flowers on the Eucalypus tree. Each year I have had it pruned in the spring. Is this why I have no flowers, and what should they look like?

6. Wound Dressing for Eucalyptus

Asked by Anonymous - August 10, 2011

I have a six month eucalyptus tree, and I wanted to know if I can trim it before I transplant it to another part of the yard. I see that I may need a wound dressing. What is it and where can I get this?

Answers
  • Applying wound dressing is only needed for larger areas to prevent infection and even this isn’t always necessary as trees often ‘heal’ themselves. A light coating of a wound dressing might also be used for cosmetic purposes. However, you may use wound dressings if you wish. Look for a breathable wound dressing for pruned, grafted or damaged plants found in garden, landscaping, or hardware stores. For better healing results, cut the branches flush with the tree.

7. Stains on Pool Deck From Tree

Asked by Anonymous - August 10, 2011

Our pool deck suddenly developed rust color stains. We can remove the stains with a scrub brush and a mild cleaner, but the stains always return within a day or two. We have a Eucalyptus tree close by. Could this be the cause? We never see any foreign matter from the tree on the deck (no leaves, sap, etc). But the stains are definitely there. It’s a mystery!

Answers
  • The tree may have a pest problem and the pests are secreting honeydew. It would be almost the consistency of water. Honeydew, though, attracts fungus, so what you may be seeing is a fungus growing on the deck because of honeydew. Check the tree carefully for pests. They will most likely be under leaves or in the crotch area of branches.
