My Black Walnut tree is leaking sap terribly. What's wrong?
Rate This FAQ
Walnuts can get a disease called slime flux. This bacterial disease causes fermentation of the sap and it will ooze out of crotches, wounds, cracks, etc. Look up slime flux on google. See if the pictures match your symptoms. Unfortunately there is nothing you can do to cure the tree if it has slime flux.
If the leaves look sap covered, it is a sucking insect. Also cankers can cause sap to ooze.

- A friend has recommended an Epsom salt solution for my garden plants. How are Epsom salts used here? I know they add mag to the soil if it is depleted but I didn't think they were used in alkaline soils... do they have any benefits? Will they help me grow blueberries etc., stuff that needs acidic soil? Research says that Epsom doesn't change the ph much but I know sulfur is good.

- I have an 8 year old Norway Spruce. It has a section at the base where the needle grow is restricted and the stems look whitish. The rest of the tree has green plush growth and it is about 12 ft high now. It had this problem when I brought it home from the nursery but I thought it would snap out of it. What is this and is there anything I can do?

- I have recently identified three large plants growing on a stream bed in my yard as water hemlock. From what I have read on-line, this is a very poisonous plant. Supposedly the stalks remain poisonous even when dead. My plants are quite bulky, and would fill at least a few garbage cans if cut down. Can you advise me on how to safely deal with these plants?
- My petunias are horribly sticky - I assume thrips are in control although I have tried to keep them washed off (insecticidal soap) and sprayed with a systemic (orthonex). Is there anything else I might try? Would a dormant oil spray work, and if so when would I use it? Also, there are small worms that are probably chomping the blossoms. What would work to prevent or kill them? How do worms can get into my flower boxes, that are at least 6 feet off the ground?
