Specifications for compost bin

We currently have three compost bins, rounds of field fencing, which work pretty well with rotation. We would like to make the 1st bin rat-proof, and assume the other two are not as critical because by the time I flip compost into them, the attraction for rats will be gone. We intend to use 1/2" mesh galvanized wire, stainless steel staples, and treated 2 X 4 wood frames, with a removable top of the same material, 4 X 4 X 4. Is a "bottom" panel essential? Does this meet your recommendations? Thanks!

Sick young maple tree

Hello, help please, I have some young blaze autumn maple trees (maybe 10 yrs old). The bark seems to be peeling, and now it seems that a fungus has started to grow on the tree. Are these signs of of a dying tree. The canopy still looks fairly good. Can this be treated with something,and or should the trunk be rapped? Thank you for your help, Paul

Doug Fir health/woodpecker

Hi, We have two very large Doug fir trees in front of our house and recently noticed a woodpecker damaging the trunk near the base of the south facing tree. I have included pictures of the trees and the woodpecker damage, wondering if this is a sign of disease or just poor health in this tree. Last year we added mulch to the area and I worry it didn’t let the roots of this tree breathe, is this a possibility for the cause of the issue and if so what can we do to help the tree?

what killed my Monarch chrysalis

Hi Entomologist, I am trying to raise Monarch butterflies and had my last 16 chrysalises destroyed by a gnat sized flying bug that came around the last 6 weeks or so and want to know what they are and how to prevent them from doing it in the future. I even built a screened shelter for the caterpillars to make sure the tachnid flies didn't get them since I had that problem earlier in the summer, but these are much different. The tachnid fly maggots were bigger and they put in about 3 maggots per caterpillar. These are much smaller and I saw one bug coming out of a bored hole in the chrysalis yesterday (see photos attached). I thought it was an ant until I saw it's wings after it fully broke through. Some chrysalises have holes drilled all the way through so it is possible to see daylight through them. Please let me know if you can help ID these nasty little demons. They are really a problem. I didn't find anything online about these. Other incidental information: they seem to swarm around the chrysalis especially when they first turn from the caterpillar into the chrysalis; I even think I saw these winged (adult?) bugs emerge from the caterpillar as it changed into the chrysalis (2 minute or so unzipping of the last skin) as though adult flies were actually living inside the caterpillar before it turned into a chrysalis Thank you for your expertise. I eagerly await your insight, John Kroll a troubled Monarch enthusiast (651-295-9985)

Morning. We have had occasional issues with springtails. Since we will be moving shortly, I was curious as to whether we should be concerned about the potential of springtails finding their way into our moving boxes and then moving with us to our new home. Is this something we should be concerned about? Thank you. Paul and Betsy

Selecting a Juniper for Deer Resistant Screening in Catonsville, less than 20 ft tall

From on-line info, looks like the Spartan Juniper would result in best result, with tight, dense foliage for a more formal appearance. However, Valley View Farm says they haven't had Spartan in stock in couple of years. Sun Nursery says Spartan doesn't do well in Maryland, and they don't carry it. What's going on with Spartan Juniper? Why so hard to find? Is it a poor choice for Maryland? If I rule out Spartan, then it looks like Blue Point Juniper may be the way to go, since it more readily available and almost as dense. Any advise on this?

ash tree question

I have what is called flowering gall on my ash tree; also was told I have ash leaf curler before I was told it was gall. Have had regular tree sprays by Swingles. Will this impact health of tree? Will it impact future leaf growth? The gall "balls" are unsightly --will they fall with cold weather, snow? We had tree pruned in winter and I wonder if this made the tree more susceptible to gall, curler? Will I get gall again?

Thank you.

dragonfly swarm

Hello, Saturday there was a swarm of dragonflies flying and feeding down the entire block above my street. I have been living in the same house in Golden Valley, MN for 30 years and have never seen this before. This is not a concern because I love dragonflies and appreciate that they are beneficial insects. I’m just wondering why this is happening. Why this year? Nothing has changed on my street. I would really appreciate it if you can give me an idea why this is happening. Thank you, George Peters

Hydrangea Lime Light deformed flowers

Hello, My name is Liz . I have a small landscape design and maintenance business. One of my clients has some issues with their Lime Light Hydrangeas. They did not bloom on schedule. Usually, its late July/early August. There are some flowers now but they look different.

I've pruned them early spring, in April, for the past 4 years. There are about 10 of them, in a part-shade location. The one located in the most sun has some normal flowers and some deformed flowers.

I've also noticed more and more dead wood, each season, when I've come to prune, as well as some roots becoming exposed, on top of soil.

Have fertilized with 10-20-10 garden fertilizer, in the spring. Have added dirt, in the past, when I see roots coming up to surface. I'm not sure if that has helped much. Maybe there is some annual frost-heave going on there? There is bark mulch down. No barriers under mulch. Client has a hose/drip irrigation system around plants.

I've been advised to hold off pruning for a season and add a slow-release fertilizer, instead. Any ideas as to why flowers are deformed? Leaves look healthy.

Not sure if this is a disease, insect problem or a soil issue. Maybe they are getting too much shade from overhead trees?

Thank you for your time,
