Can you help me identify what is eating my garden? I can’t seem to get on top of it. Thanks in advance
This actually looks like shothole fungus, or one of its relatives. I would treat with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
Sometimes I come upon a batch of tiny red or yellow spiders all concentrated on a web. I used to just spray them with bug killer, but now I'm thinking they might be beneficial. What species of spider are they?
It would be impossible to give you an answer without photos, a description of what you found them on, and if these were on your plants.
If these are very hard to see, and this webbing is occurring on your plants, then you may have a HUGE problem. Spider mites will make short work of any plant.
Please include photos, and as much detail as you can, and I will be more than glad to help.
Unfortunately, without knowing whether this is a plant eating mite or an insect eating spider, it would be difficult to give you a straight answer.

I have previously only had a pot balanced in the top of a chimney pot and snails & slugs crawl up from the bottom inside. Now I want to plant a clematis more permanently to grow up the garage wall. Without cementing the chimney pot down, how can I fill it with growing medium but deter slugs and snails? Thank you in anticipation
