Unknown weed

In my last batch of hay bales I found this weed. What is it? Will it hurt my horses?

What is this plant ?

This deciduous plant started to grow on a pile of wood logs. We liked it, so moved it in a better spot of the yard. Its size tripled in four years. How big will it get and how do we prune it?
Thank you

Growing Grass

My 40-year old tree died and I have been trying to plant grass where it was without success. Using a commercial grass seed and fertilizer mix on several occasions have not produced growth. Is there something I can do this winter that will facilitate grass growth in the spring?

Need help identifying tiny jumping insects...

I was outside putting up Christmas lights today and I saw +100 tiny bugs that jump like fleas on a stone slab in the yard. They are about 1mm. Too small to see any detail.

I took a picture of one with my iPhone 11 and can see that they are sort of flat and look to be brown hard bodied with yellowish/orange legs and head with long straight antennae. (The antennae almost make a prefect right angle that points to the center of the insects head.)

*Pictures attached are taken as close as possible with an iPhone 11.

ALSO, i found a swarm of small winged insects in this exact same spot in the middle of summer. They looked sort of like ants with wings and I assumed they were some kind termites. I have no idea if they have anything to do with this new swarm of tiny bugs, or if they were in fact termites, but figured it might help to mention it.

Nut trees for Delaware

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.

Compost in the winter

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
