All kinds of trees dying

I see all kinds of trees dying. I did a test which shows there are high levels of Aluminum oxide, Barium and Strontium. All these ingredients will kill tree roots slowly and have almost immediate adverse effects on the leaves. The trees look like they are dying from drought but it is due to having no roots

Have you ever examined the contents of the rain water?

Unwanted moss

What is the best way to get rid of moss in dirt and flower beds and keep it gone? I live in Washington state and our yard is mostly shady with many fir trees. Can I use a lawn moss killer with nitrogen and iron? Should I be using a pre-emergent like Caseron? The moss is also invading our lawn even after we had it professionally killed, thatched and reseeded. How do I get the soil tested for pH? I’m thinking I need to add lime to raise the pH from all the acidic fir needles over the years.

Propagation Reference Guide - referred to by Mohan G. N. Kumar in the 9 page article he wrote

Hello, Regarding "Propagating shrubs, vines and trees from stem cuttings" by Mohan G. N. Kumar, which I was able to print out for myself he mentions " the companion Propagation Reference Guide with 117 of these plant species and cultivars" How do I order a copy of that publication? Can you give me the information I need to do that please? As I want to propagate an hydrangea, a dapne odora and a rose I would love to have more specifics regarding these particular shrubs. Please let me know as soon as possible. Many thanks, Susanne Ashland

Keeping blight from spreading -- planting trees in an area that has had blight

I have a question about filbert blight. I live on Samish Island in Skagit County, WA. Samish Island used to be prolific in terms of filbert production. Several "neighbors" who live a mile and a half or so away, however, have had to pull their trees due to blight. That's a pretty fair number of trees. Before we knew this, we accepted 4 "starts" from one of these neighbors. On our side of this small island, a mile and a half away from our blight-infested neighbors, we've never had blight that I know of. Except the four starts that we took in from those neighbors. We've planted all blight-resistant varieties on our property. All seem to be doing great. Good nut production. Between 2 and 8 years old now. Maybe 25 trees. Here's my question. We just dug up the 4 "starts" from the neighbors because their blight finally showed up, years after planting. These trees were all 10 years old or so. Our yard is about 1/2 acre. We have several filbert trees that are not far from the blighted trees. (Between 20 and 200 ft away). All are Santiam or Yamhill (blight-resistant). Or Jefferson. Is it foolhardy to plant new Jeffersons in the holes from which the infected trees were just taken? Without thinking, I ordered the new trees. I can probably cancel the order if I act fast. I can't think of anywhere else in our yard to put the trees (we're almost full up). One other caveat: I recall a neighbor telling me about planting trees in a heavily infested area -- they were "blight-resistant" but got it anyway. Thank you for your advice!

Ghost Mantis Oothica?

Hello, I recently kept a group of 8 "Ghost Mantis" over the last year.

I recently lost the last one and went though with cleaning out the cage, Now I noticed these several months back but left them untouched (not knowing exactly what they were) Until I was able to get some pics today.

Can anyone tell me if these are egg sacks of sorts? and if they will be hatching?

Doug Fir with falling needles

Hello, i Have a large fir tree and needles seem to be falling. Sections of interior branches seem to be yellowing. It all seems to have happened in the last three or four weeks. Before that it was looking very healthy. What do you think? Thanks

Fir trees have dying branches

I recently had my 10 acres of timber professionally thinned out back in June. All of the trees are fir and they are about 30 years old. I just noticed last week that some of the trees have a few dead small branches hanging of the bigger mane limbs. I don't know if I should be conserend or not?
