I have recently started my journey into caring for plants. I started with a Bonsai (juniper), and got Myrtle Topiary and a Cycad. Since the winters in PA can get a little rough and the temperatures have dropped. How do i maintain these plants? I don't know to much except water and not over water. I'm not sure what kind of food they take or when to feed them. Is there any resources you know of that can help me get a basic foundation? I really enjoy plants and I want to keep growing!
Generally, care for plants during the winter is pretty easy. I will include several articles that you will find helpful.
