I will buy this planner every year!
Format: Book Supplement
I had a 2025 Old Farmers Almanac Planner and loved it. I had to get the 2026. This planner is perfect for me. Shows the month at a glance, but then has the day pages where you can put plenty of notes!

A nice themed planner
Format: Book Supplement
Not a garden/farming planner. Just a regular planner with some Old Farmers Almanac rubbed on it. Really well made and nice looking but not really super special or helpful for farming or gardening.

Great Book
Format: Book Supplement
Been buying this Planner since 2022. First year I bought it for myself. 2nd year myself & my bestie. 3rd year myself, bestie & another friend. I’m sure you get the idea. 😁 I keep up with daily weather predictions on the calendar page & daily activities, of any type, in the days of the week section. I can see when I planted a crop or when I SWR the bed (for those not in the know it means strip, wash & remake the bed). My youngest daughter got a real kick out of that one. Told her when I passed she could read them all & try to figure out what the heck I was talking about. *LOL* Great book, beautiful renderings & interesting tips & notations.
