Coreopsis Zagreb

I have four plants of coreopsis Zagreb and last year some parts had brown stems. They now are one big bunch. A part near the right middle did not come up yet the other areas are coming up nicely. I don't use mulch. Can I plant another coreopsis Zagreb in that spot if I dig out the old dirt and put in new? Thank you.

Not sure if fig tree is alive or dead

Hi,

I live in Laurence Harbor, New Jersey and last year I planted a very small fig tree. He grew nice over the Spring , Summer, and Fall. I didn't cover it and now it is the middle of April and I don't see any buds or signs of life. I have included 2 pictures of my fig tree. Please let me know what you think. The 2nd picture is hard to tell but when I scraped the branch there is a hint of green on the stem

Best Regards,

Vinnie

Can you identify this undesirable grass?

I've done my own lawn maintenance for 30 years and this spring I suddenly see large patches of this stuff everywhere. I don't think it's crabgrass. I'm hoping I can control it without resorting to something like Roundup.

Do barred owls just keel over and die?

Hello. I came across a youngish barred owl the other day on a walk, and it looked as though it had fallen from a tree very suddenly. Its feet were still in that rigid roosting grip and its wings were tight against its body. Also it was entirely intact--no blood and no predation, though it looked as though it had been dead for a day or maybe longer. I thought it might have died of a heart attack, but the internet seems to contradict this. Any theories? Could it have been poisoned, based on what I've described? I really appreciate this service. Thank you.

Invasive tree or not?

I'm looking for some info on the snakewood tree or acacia xiphophylla in the family Fabaceae. My husband picked up some seeds somewhere and they have germinated but we read it's an invasive species. We don't want to plant them only to find they're a nuisance. They make for very pretty wood. I've checked with Rutgers NJAES with no results. We live in NJ. It's been several days since I asked this question(10 days). Thanks

Plant Identification

Hello, I planted several of these a few years ago and I forget what they’re called. They’ve spread throughout my gardens. Can you tell me what this is?

Time to apply corn gluten in Spring

I was wondering if it is too early to apply corn gluten to my lawn? It says wait until crabgrass germinates in our area, but I'm not sure when that is.

swiss needlecast fungus on my douglas fir

I have a very large douglas fir in my yard that was diagnosed by someone at Ronnys Garden World with Swiss needlecast. They said to wait until the new candles are half grown and spray with Infuse, then again several weeks later, around July. They stressed that timing is important and I would have to spray for at least 2 years. The tree is out in the open in a large yard, and I don't have any close neighbors. Ronny's suggested that I contact your office for further information. Any help you can give would be appreciated. Linda Robinson. Thank you.
