Most of the apps help you identify plants, of course, and pests. And give you growing instructions.
But there is also an apps for your garden to-do list, which includes a way to take pictures of your garden and assign them to tasks.
There is Flower Garden, by Snappy Touch, which doesn't help you in your real garden, but allows you to plant, water and grow "virtual" flowers then clip and send bouquets to friends.
My Garden, by Perceptive Designs, might make the most sense for most of us, although there appear to be some "bugs" in it. It allows you to keep track of the plants in YOUR garden, with all the information you need through the season.
The prices for the apps range from $9.99 to $1.99.
I am thinking about an app called "Dialing for Flowers." I just don't have any idea what it would actually do.
