Juniper shrub dying

I have sections of my 20 year old juniper shrub dying. I don’t see insects. It was pruned last early fall but no dieback noticed until the past month. Should I just cut the dying portions out?

What is this rock?

Wondering what this rock is, its about 5-6 inches tall, and has a pretty good weight on it, Id say about 1.5 pds. Also, I put a block of ice under it and it absorbed pretty quick and the rock got noticeably colder. I was told that it was a meteor found in Brazil? Can anyone confirm what it actually is?

winterizing roses

Can I use fallen pine needles to insulate cut-down rose stumps? It's been 6 years since I last short pruned my roses, as I usually just thin them in the spring. I cannot afford clean straw (that doesn't also have rye seeds in it) so I wonder if I can use the Austrian pine needles that I'm raking up for fire defense? I don't usually let pine needle mulch touch any of my flowering bushes during the summer. So I need to know what I can use this winter?

Browning Chinese Pistache Leaves

Good evening -

We have a Chinese Pistache tree that is approximately eight years old. It is a beautiful tree and, until recently, appeared very healthy.

Recently, several leaves have gone from mottled with spots to completely yellow with brown spots (photos attached). We are very much hoping that it is not vericullum (sp?) wilt, which we understand is fairly common but which is supposedly untreatable.

I would be grateful for your thoughts as to what may be ailing the tree. Many thanks.

Native Trees and Plants suitable for yards

What native species and drought resistant, plants and sources/suppliers, can you recommend for yards or open spaces in the Holbrook JCT, Topaz Ranch, Antelope Valley areas of Douglas County, Nevada? Pinion monophylla (Nevada pinion pine), Thuja plicata (goldie pine), Pinus strobus (white pine), Artemisia tridentata (western sage), Purshia mexicana (cliff rose), Perovskia atriplicifolia (russian sage), or Rabbit Brush (orange blossoms, species unknown). For some of these, I can collect seeds, and some plants, but I am unsure of the best way to raise seedlings.

Leaf footed bugs infesting my pomegranate


My pomegranate tree is infested with these leaf footed bugs. I've had a running problem for the last few years and haven't been able to eradicate them. I am pretty much an organic gardener and don't like to use dangerous insecticides. I have used Neem oil in the past, but I still have this problem. I may not be using it at the correct time of year?? Please advise.
