Gardening apps are so helpful when trying to identify plants, pests or weeds ‘on the go’. They are improving all the time, supplanting manuals and textbooks as the way people dig for information. Many University Extension services are developing digital aids to extend outreach to clients. This is helpful when we’re searching for reliable, research-based information, as it’s always wise to have a critical eye when searching online.

Here are some links to current applications (updated March 2021) to get you started. Do your research to find the best and least expensive options. Look for online reviews as most apps have been tested and rated by other gardeners.
