avocado leaf bugs

On a whim I stuck three avocado seeds in a planter a year ago. Now I have 3 avocado trees about 3-4 feet high. While taking a close up of the leaves today I noticed several leaves (not all of them) have many small white whisp-like things on them. Dust but not dust. Are my avocado trees infested with something? Is so, what do I do about that?

Invasive plant in gardens

HELP! I am doing battle with a a plant that is choking out everything! It has narrow, purple leaves and a dense mat of roots. It grows to about 24 to 30 inches with spikes coming up later in the season. Last year I thought my partner had planted something and I let it grow. She did not, so I dug out large mats of roots last fall. The mats are back with shoots coming up so I am digging out large sections of planting beds again with no expectation of success. All ideas are welcome and thank you.

Issue with Mars Seedless Grape Plant?

A customer just brought a Mars Seedless Grape plant to our Extension office in Potter County, Pennsylvania. He is concerned about the liquid balls "bleeding" from the plant. Can anyone tell me if this is a negative issue related to grafting? Or if it's a normal physiological property of the plant?

Blight in the garden

Hello, last year I have blight on my tomatoes and cucumbers in my raised cedar garden bed. Last year we moved, I tossed all the soil and took my raised beds with me. My question is I have placed my bed at my new home filled them with new leaf grow, composted humus and manure etc. Do you think I will have a problem with the blight being in the wood? I don't use chemicals in the garden, but before I plant my seedlings do I need to treat the wood/soil? I have also sanitized all my starter pots that I started my seeds in. Thank you!

If the tree shows signs of ash borer is it to late to treat? What should we use to treat my problems. Broad leaf is really bad this year on my yard in Jefferson county. What should we used to eradicate these weeds without messing up the yard. Thanks in advance for the response.

wild apple

On our homesite in Wabasha County, we have a single (wild?) apple tree that produces delicious fruit. It seems to be very resistant to diseases and bugs. It ripens to a rich, dark red color almost approaching black. We don't know anything about it. If you think it might be worthy of interest please be welcome to use it for research.

Plants that poison dogs

We have had repeated episodes in both our (large breed) dogs that seems to be some kind of poisoning. It seems to have nearly instant effect, affects their cardiac systems (extremely fast heart rates) primarily, and causes severe pacing, anxiety, and distress. Veterinarians have no idea what it is. It seems to be prevalent and most dangerous in early to late spring. We have had times where they nearly drag us across the yard to get at a lawn weed that seems to have some extremely powerful attraction to them, but no one seems to know what it is. They have access to both landscaped areas and pasture land (without other animals -- that we know of). Some notes are attached below. We also have mushrooms on the property, but the dogs appear to leave these alone. Can you help or even direct us for an identification or solution?

heating cables for starting seeds

What is the best method for using heating cables to start seeds indoors? I have a bed that has a floor of a sheet of insulating board to which I laid heating cable, over which I put 2 inches of contractors sand. the cable is warm until I put the sand over it then it seems to quit. The surface temp never seems to rise above the ambient air temp. The cables do not cross. The rows are approx. 1+1/2 inches apart. Should I use less sand, or a finer sand, nothing, or some other medium?

Bed Bug?

This is Micah Johnson, I'm a family physician. A patient of mine brought this bug after he was bitten at night and he found this bug next to his bed on the floor. He had a scar on his arm that was suggestive of bedbugs. However, the bug he brought was a bit larger than expected for a bed bug.

I may be able to get some better pics if these aren't clear enough. Also what can I use to rid my yard of these pesky weeds.

Odd pruning of trees

I have seen over the last number of years medium to even large trees being pruned back very heavily, almost like shrubs. I've always understood this to be potentially harmful to trees. I'm assuming they are trying to obtain a more contained and rounded form? Any ither ideas why one would do this or if they should? I'll attach a photo. Thank you!

I am discovering different perspectives. most of the grounds I have saved are 1 to 2 months old. Can I use too much? any information would be helpful

low maintenance dwarf apple tree

I want to buy a low maintenance dwarf apple tree that is disease resistant (i.e. requires minimal spraying for pests) and perhaps would be cross pollinated by nearby crab apple trees, if possible. Does the Liberty variety meet these requirements? If not, what variety do you recommend? Also, I'd like to know if any pecan trees are adapted to central Iowa winters. Thanks

Denver lawn - starting over

I am buying a Denver house that has nothing but dirt and weeds for a yard. This is a golden opportunity to draw up a great landscape plan and really improve the place!

My question is about types of grass for the lawn. We will be installing a sprinkler system, killing the weeds with an herbicide, and preparing the soil.

I found your publication, "Renovating the Home Lawn" ( to be very helpful. Still, I am not sure what types of seeds to use.

I'd like a variety that can tolerate sun and some foot traffic. A nice, thick, even, green turf would be lovely, but I am a realist about living in a semi-arid place. I don't want to water too much, and if the grass could withstand a drought period, that would be good, too!

In other words, I want it all! Any suggestions?
