Rhubarb breaking ground in Janunary

I have new Rhubarb plants growing in January. I started these plants from seed in early 2019

and transplanted outside when they were large enough and they did very well over the summer.

I am concerned about this early growth. A couple had leaves. What do I need to do to save my plants.

Thank You

So confused! Seeing so much conflicting information about airplants and copper. Even though toxic to these plants, DIYers and so-called experts display together, without a "shield" between them. My local greenhouse explained use of said "shield" is needed. So, if I use a different kind of metal, as in craft or hardware-type wire, will my plants be safe?

Shriveling Morning Glory Flowers

Alright, about 6 or so months ago I got a packet of morning glory seeds, and up until recently they've been growing perfectly fine (I have them indoors). However, now that I'm starting to get flowers to bloom, right when they're about to open up, the petals instead seem to bind together, shrivel up and die. The vines are doing extremely well, I water them about once a week, and I cannot pin point a problem. At first I thought it was because I turned on an oil diffuser in the same room as them, however it's been turned off for about a week now, so I don't really see that being an issue. The flowers grow absolutely fine until they're just about to open up. I'm just confused on how to fix this problem because I can't seem to find anything online.

Rhododendron- horizontal stripe on bark

We recently notice horizontal lines on the truck of our rhododendron. It’s about 5’ from ground and occurred in the fall. This is on every trunk at the same height. The line are quite small and looks almost man made its so precise. We live in the bucks county area. Thanks

Lawn care

Our lawn in Mercersburg PA is about 3 to 4 inches high now, on November 8th. Is it too late to cut it before winter? Is it best to leave it unmoved until Spring?

Thinning leaves

I have three very large Holly trees in my yard the one in the middle looks to be much thinner in leaf Mass then the other two. I started noticing this about a year ago in around that same time some bark broke off the very bottom of the trunk of that tree. I'm wondering if it's anything I can do for that tree it shows no other signs of disease and maybe there's nothing wrong at all but I'm not sure I don't want to have this holly tree die if I can help it. All three of these trees are at least 50 foot high. So if you have any suggestions please let me know. Thank you

Tree or Weed leaf identification

Hi, I have spent my whole life working outside and have a good idea of what kind of trees there are. However on a recent job in Philadelphia I came across a leaf design I have never seen before. Any clues as to what it is? Thanks Bill
