If you're looking for a garden planning tool that suggests the best combinations of plants for the highest yield and best pest resistance, AIGardenPlanner is worth a look. The tool uses artificial intelligence to offer advice tailored to your specific situation, plants that are best suited to your area and the best pairings for natural pest control. It also offers more general advice on planting, pruning, growth habits and pest control, so it's good for gardeners of all experience levels.
Another useful tool is PictureThis. Although it's geared more for plant identification and care, it offers detailed care advice and tips on watering, lighting and feeding. Its AI system can also be used to diagnose plant diseases and recommend treatments, which can save you time and ensure your plants stay healthy.
If you want to help with biodiversity and conservation, Pl@ntNet is an interesting project. It uses AI image recognition to identify plants, but you can contribute to the project by reporting observations that can help improve the AI algorithm. It's a community approach that can help you learn about and identify plants, and improve your gardening skills.
Last, Cropwise could be of interest if you're more focused on farm operations. The digital platform offers a range of apps to help optimize operations, improve crop yields and make decisions. It's more geared for large-scale operations, but it offers practical advice to help you avoid rework, improve yields and make data-driven decisions.
