dormant spraying

Can I accomplish anything by spraying copper now in January and Lime Sulphur 3 weeks later. I have Anthracnose on some trees and was not able to spray copper before fall rains as late apple harvest into November. Is copper only for Fall clean up before rains? Makes it difficult here in the NorthWest.

Small to medium tree or shrub recommendations for wet spot - Portland, OR area.


We recently had a plum tree removed in the corner of our yard. The are is at the bottom of sloped area. The arborist indicated the soil appeared to be poorly drained.
We had an exceptionally high rainfall this past year. This area also has an easement for public works access - there is a manhole located in the area which requires periodic service. This plum suckered badly and was a pain to maintain. The broad canopy was very attractive and provided light shade.

I would like to plant another plant in this spot which tolerates wet feet but does not have an extensive root system. I am concerned this could possibly pose a problem to the drain. system

I would like a plant which grows upright and could have a narrow or medium size canopy. The planting area is in a corner spot. A brick wall which runs along the area and screens our private yard from a main road. THe neighbor in back has a cedar fence as a divider in back. The brick wall and cedar fence intersect to form the corner spot where I need to plant.

Desired plant function: provide screening from the main road and neighbors.
I would like something with attractive foliage which provides screening and possibly offers wildlife protection. Berries or flowers would be a plus.
Max desired height estimate is 20 feet.

Mildew on frames

I recently lost a hive (absconded) and allowed the remainding hives to feed on the honey that remained in the super. Rain prevailed for a couple of days and the frames turned black with mildew. Can I continue to use these frames with new foundation or should I discard them???

Native ground cover

I have a new home sited on an acre, near riparian area, at the 1,600 ft. level on Mt. Hood and would like to restore the native meadow that once resided here. Currently the ground is frozen and muddy. Is there a ground cover, like clover, that I could seed to help establish the meadow? Or is there meadow seed for this elevation?

Compatibility of xeriscaping and established trees: eastern Wyoming

Before suggesting to town administrators that a landscaping rebate program called "grass-to-xeriscape" be considered for the small eastern Wyoming community where I live, I want to know if any research or studies have been done on the long-term effects of reducing supplemental irrigation water to established trees of various species including cottonwood and elm. This program, adopted in Mesa, AZ, has been very successful in reducing water use for residential landscaping. However, I am concerned that cutting back on lawn sprinkling may have an adverse on the health of mature trees, particularly in the current circumstances of declining groundwater levels. I would be grateful if someone could help me locate useful information.

What are these insects?

On Jan. 19, 2013 between 3 and 4 pm, I took thirteen photographs of some sort of swarming insects in the sky behind a large Juniper tree in my backyard. The temperature was around 50 degrees and there was a light breeze from the SW. Do you have any idea what these things might be?

Swallow nests

Our development has been plagued with swallows the past several years. We've tried the usual methods, including a BirdSlide type solution, with limited success.

The source of the mud for the swallows is a lake in the development which develops a mud ring in the spring due to low water level. I was wondering if there's something we can put on the mud ring while the ground is still frozen that would discourage the swallows from using the lake as a source of nest mud.

Absent that, I found an online reference that claims spraying the nesting area with canola oil worked ( I'd appreciate your thoughts on that option.

Lime on pasture

We have a problem with moss in our pastures/hay field. Should we apply lime to these fields. If so, should we apply it now(winter) and can it be put on without working it into the soil? We have about 10 acres in pasture.We also have a small tractor and spreader. Thanks, Ron

Growing Degree Days

I previously asked a 3-part question, all related to GDD (question #112872), but only got an answer to part-1, so I'll re-ask the rest! If I'm limited to one question per submission, please let me know that's the case.....

1. In my research about GDD, it seems like it is primarily applied only to farm crops & to woodies (trees, shrubs, and vines), not to herbaceous perennials found in home gardens - is that correct (because I haven't found any web sites focused on pests of herbaceous flowers)?

2. If I find GDD numbers for a particular insect from another geographic area (say California), wouldn't it still be applicable here in Michigan, as long as our Michigan accumulated GDD count is used - is that correct (e.g. a GDD number for a specific insect is good and useable in other areas of the country, as long as the GDD of that other area are used)?

Hay for the Cushings Horse

I have a 24 yo TB that has Cushings Disease. We are moving to Montana in April. The hay at the facility where she will live feeds alfalfa. I am unfamiliar with the varieties. Someone mentioned "alfalfa 200". Could be wrong?
I have read in the past that alfalfa is not good for the Cushings horse. Then, recently, I read some statistics suggesting that alfalfa is probably the best choice for a Cushing's horse.
Not being sure that I have all of the info you need to answer my question, but, in general, is alfalfa hay a problem for this horse? Or do I need to use caution when feeding a specific variety?
Thank you very much!

A gentleman came into our office inquiring about what may have caused his tomato, squash & cucumber plants to die out last summer. He said that it would start from the bottom of the plant and die out upwards into the vine of the plants. He wants to know what would cause this and how to get rid of it so he doesn't have the same problem this coming year. Thanks!

mold on outside of home-canned tomato jars

My mother has some home canned tomatoes (canned in 2009) that ended up with mold on the outside of the jar. The mold occurred after she had a basement leak she did not know she had (in 2011). She wiped the mold from the jars with no regrowth of that mold on the jars. She is hesitant to use them but hates the thought of throwing them out. What should she do? Is there anything she can do to reassure herself?

What kind of grow lights do I need

I am going to start my vegetable garden soon indoors and was wondering if you would give me information on grow lights. I would like to know what kind are the best and what light spectrum do I need. Also, where can I find them at a good price. I am going to be planting tomatoes, cucumbers, green beans, peppers, and squash. I tried it last year and bought some lights from Home Depot but they were too hot and I couldn't get them close enough to the plants without burning them up. Needless to say my plants shot straight up and didn't fill out.

Growing Degree Days - Questions & Clarifications

1. In April 2013, the MSU Enviroweather site ( seems like it will close for public use and it will be by payment/subscription use only, eliminating the home gardener from use, unless they want to pay for it (even though we pay taxes for MSU) If so, any idea of the cost? Are there any public/free sites you'd recommend as alternatives for the home gardener - The Weather Channel seems to have a GDD calculator, but a start date is needed: would it be March 1, 2013 (that is what Cornell seems to use -

2. In my research about GDD, it seems like it is primarily applied
only to farm crops & to woodies (trees, shrubs, vines), not to herbaceous perennials - is that correct (because I haven't found any web sites focused on flowers)?

3. If I find GDD numbers for a particular insect from another geographic area (say California), wouldn't it still be applicable here in Michigan, as long as our Michigan accumulated GDD count is used - is that correct (e.g. a GDD number for a specific insect is good and useable in other areas of the country, as long as the GDD of that other area are used)?

Putting in a New Lawn

I am going to start a new lawn. The current lawn is close to 40 years old and in really poor condition. I want to make sure that I am touching all bases accordingly. First, I will need to get a soil test. I have read excerpts on how to do this. However, I would like your assessment because I know that you are known to be the best in agricultural issues in the country. Please tell me when I can take the test, how to do the test correctly, whether I need a soil kit or not, and where to send the test.. Please also give me a "heads up" on crucial points to remember in this process. I appreciate your expertise very much.
