I saw this on a tree on the Pennsylvania side of the WCC park, just past the border. Was wondering what it is or if it is invasive.
I need some advice, I need to clear 6 acres of established 30 inch plus dog fennel In Millsboro . Will this be possible and how long will the project take to accomplish the result is for use as equine pasture
Hi. I’m interested in planting a nut tree(s) on my property in Hockessin but I don’t want to plant a Black Walnut because of its negative impact on surrounding vegetation. What other types of productive nut trees can be grown in Delaware? Are we too far north for Pecans? Are their lesser known nut trees that are full size other than Black Walnuts that I might be overlooking? Any help you can give me would be greatly appreciated. Thank you.
Would like to know what kind of snake is this and how big do they get. Thank You

We have a compost bin that we have been collecting food waste in all summer and we are here only for the summer. The compost is not ready yet so I would like to leave my compost tumbler to sit. Will it be okay to sit through the winter (in Delaware)? Would it be better to leave it on our shed or outside? Here is a link to the tumbler we have. https://www.lowes.com/pd/RSI-Tumbler-Composter/1000678051?cm_mmc=shp-_-c-_-prd-_-sol-_-google-_-pla-_-106-_-sosgardenhardlines-_-1000678051-_-0&placeholder=null&gclid=Cj0KCQjwzbv7BRDIARIsAM-A6-0uoO8tJkuEmhQlMRhaRFJ2GJe1Qg_-WNxMMUhIoY04R_Cb393TPAoaAtrsEALw_wcB&gclsrc=aw.ds

Hi, sorry if this is a duplicate question, network trouble. 2 photos attached. On the close-up, can you confirm that this is botrytis, or do I need to bring in a sample for analysis? I'm treating it as such, cutting the plants down for fall and disposing of the debris safely. On the second photo, the brown and yellow plants are all peonies, 6 in all. Are they too close together? Do I need to dig some up to make space or can I just cut back some stems in the spring? Thank thou.
Dear Cooperative Extension: What should use to top dress my lawn this fall? I was thinking of using Leafgro for the top dressing, or is it better to use topsoil, or a mixture of the two? I have regular fescue (cooler weather) grass and trying to get rid of the clover, by digging it out and/or using IronX. This is leaving patches with no grass or thin grass that I want to reseed, along with top-dressing the whole lawn to give it more organic matter. I live in Silver Spring, MD and did a whole battery of soil testing through your office in 2017. The soil pH was in the optimal range (around 6.8 on average across the front and back lawns); while the P, K, Mg, and Ca were all in the excessive range. The organic measured 10.6% in the front lawn and 8.2% in the back lawn. Thank you!
