Best Lawn Seed For Sussex Cou

New lawn. The contractor used a seed by the name of Wintering Green. This seed was not included in a list as a good seed for this area. Anyway it looks really bad. The contractor told me it does not take heat very well. He came by and sprayed it for a fungus that developes during hot weather. I cannot find any information on this seed. Thanks for any information.

Bagworms identification and plants to check

I have seen the response to the question regarding treatment but I am wondering if there is a fact sheet or other resource you recommend to learn how to IID bagworms and what trees and shrubs to check. It would be nice if all: ID, plants and treatment were on one source. Thanks for your help

spotted lanterflies

I would like to use yard waste that I have gathered from the home of my cousin who lives in Pottstown, PA. They are in large paper yard waste bags and tied down in the back of my pickup truck. I have not taken the bags out of my pickup yet because her neighborhood has been infested with spotted lanternflies. I did not see them at her home but I have seen them at the homes of other relatives who live on the same block. Should I bag them up in plastic and throw them out or is it safe to put these weeds and plant clippings in the layers of a raised bed that I am building up over the next week?

Fall veggie crops

Hello, My name is Adam West and I'm the youth director at Aldersgate UMC on 202. This spring we created 6 raised beds to grow crops and take down to some of the local food banks that we support. We had a lot of success with our summer produce and are looking for ideas for fall and winter. Most of the knowledge of our team centers around summer produce. Do you have some ideas for what we might plant in July that we could harvest in the fall or winter?
