Way back in 2003 I wrote a newspaper article about using a Palm PDA (personal digital assistant). In the years since, Palm has gone out of business and many of us use smartphones daily.

I use mine all the time: to look up plant names, to check what I've written about a topic, and to find directions to a garden I'm visiting.

There are several smartphone apps that can be very helpful for gardeners.

Rather than try to research each one, I found this article in the New York Times that seems to cover several good ones.
