If you haven't already, now is the time to put away your motorized gardening equipment. Drain the gas and the oil, repair and replace any parts that need maintenance including filters and spark plugs, clean the dirt and grime away, cover and store it for the season.
Dogs and other animals like to get into ponds. I cover them with wire to keep them out. I place sticks under the wire to hold it up because they do walk on it.
I use an old metal milk crate to sit on when I pull weeds. It is a lot better than squatting or on your knees. Paint it so that you can find it easily in your yard. Plastic milk crates would probably work too.
If you have chickens or other animals that like to scratch in your containers, put wire over the top of the containers.
Use tomato cages in flower pots to hold up plants that like to grow leggy and need extra support.
