Lilac tree concerns

The tips of the leaf’s on our Lilac tree are changing from green, to light brown, to darker brown. The dry brown leaf then curls and looks dead. The picture is representative of our entire tree. At first we thought aphids and used ladybugs to no avail. Can you Identify the cause and treatment to prevent this from happening next year? Any help would be most welcome. Best Regards

Spruce beetle - alaska forest fires

Can a foreign predator be introduced at regular intervals to eat these beetles to offset a cost of global warming. Like maybe Preying Mantis?? Just a thought. Ps - I’m from NY area so I don’t know what could be introduced to your habitat with minmum negative impact but would eat those beetles.

Lynx Spider?

Is this a Lynx spider? If so, I thought they only lived in Southern states and Africa. It’s on the side of a lawn chair. Tiny, and neon green colored with a light brown center.

Plant ID Request

I have a plant with broad leaves with well defined veins and small yellow flowers. I wondered if it was in the mustard plant family and whether the leaves might be edible in salads, but did not want to try it before confirmation. Thanks for any info that you can provide. Larry

Rose Tree of China dying

Our RTofC is dying after 25+ years of good health. It is turning brown quickly. Our neighbors tree looks like it is going also. There are small holes in the leaves that are still green like it is a bug eating it. Is there a known cure to save this beautiful bush?

Best flowering plants, trees, shrubs to attract pollinators and birds?

I live near Russian Jack Park and want to plant things that will attract pollinators and birds. My front yard faces south, the backyard is partially shaded. I prefer to use native species, and species that won't spread out of control without constant pruning.

Is this a moss?

I have this in my garden plot (C Street community garden). I've been told that it is a moss.

A few years ago, I had a little of it. Now I have a lot of it. I pull it up, and it takes a slab of dirt with it.

I don't have much in the pathways where I walk. I lay strips of cardboard between the rows to try and keep the weeds down, and it doesn't grow under the cardboard.

Is this a moss? I have a little regular moss here and there (I'll call it fairy moss), but this other moss (I'll call it smurf moss) is really spreading. Is it helpful to a garden?

Thanks for any help you can offer.
