If you're using this handbook, start by skimming through the table of contents to find the information you need. It's great for planning your vegetable garden and learning cultivation techniques. When handling the book, be gentle because the binding is stiff and fragile. Try not to open it too wide to avoid damage. To maintain it, store it in a dry place away from direct sunlight. This will help prevent further yellowing of the pages and keep the covers in better condition. Don't worry too much about the soiling and minor tears; they don't affect the valuable information inside.
