Peony leaf insects

At this time of year my peony leaves are showing signs of being chewed on. They look like a hole punch has been used around the outer edge of the leaf. I also notice similar damage on lilac leaves. What can I do to prevent this?

Can I pressure can with this antique pressure cooker I inherited?

I have received a "Steamliner Pressure Saucepan" (I believe it says model C-6) A photo is attached. It does not appear to have a gauge of any sort and no instruction manual that accompanies it. Can I pressure can pint jars of food in this unit? If so, at my elevation (in Missoula, MT, 3200') how long should I do this for? Thanks in advance.

sanfoin growth

We have a sanfoin stand, put in last year, not harvested last year. Pivot irrigation. It initially looked pretty good, but it is now about 1 foot tall, kind of thin, and starting to bloom. Will this continue to put on tonnage after it starts to bloom. Should we cut it and hope for a better second. It would be luck to make 1 ton to acre right now.

pasture mix for sheep

We have some wet, heavy clay, high pH high saline pastures we graze sheep on. We rotate through these pastures during the summer. We can run wheel lines, but usually the ground is moist enough it is not required. What would be a good pasture mix.

Girdled Quaking Aspen

2 winters ago our 20 foot aspen was girdled by a mouse. This spring it began to bloom, but quickly shot up a new sucker from its base. The sucker is thriving. The main tree now appears dead. Any suggestions on what we should do with the main tree?

Populus tremuloides quaking aspen

Dear Expert,
We planted several quaking aspen too close to our buildings many years ago, so we have cut them down this last spring. The problem being the roots are still sending out shoots and we don't know how to rid the lawn of them, even though we had the stumps ground out.
We would be very appreciative if you could advise as to how we can handle this problem.
Best regards,
Mary Lou Johnson

anjou semi-dwarf pears

This will be the third year for my tree to produce fruit. I am having a difficult time determining when the pears are mature enough to pick. The tag that came with the tree states to eat fresh but everything I read about anjou pears is that they need cold storage first and then they need to be ripened on the counter for several days. I would appreciate your advice on this matter.1. Time of year to pick 2. Cold storage necessary 3. Length of time in cold storage and counter ripening if necessary. Also, is there a safe way to treat/ protect the tree from insects that still allows the fruit to be edible? thanks. P- billings mt

Sick aspen


I'm seeking help for a sick aspen tree on my property. When I bought my house 12 years ago, I had a total of 5 aspen trees in my back yard. Three of them have died, so we took them out.

I have two that are approx 30 feet tall and the trunk is approx 7" in diameter.

One is really green and healthy, and the other has smaller yellow leaves (all season), and for as long as I can remember. I'm not sure if they are the same variety or the one has been sick for a long time. The leaves are much larger on the healthy green aspen tree. I will attach a picture of the healthy green leaves on one aspen vs the small yellow leaves on the sick tree. They are planted approx 4 feet apart.

I will also attach a pic of the yellow leaves with brown tips and now spots.

In the past week, all the leaves are developing spots all over.

I planted a young aspen a couple years ago, to replace my last one that died. Will it get sick too?

How and when can I treat this tree? If its possible to save the tree.. I've read about iron deficiencies and several fungus diseases. I'm confused and don't know where to start.

I appreciate any help you can offer to save my tree.

Thank you,
