In October, plant festivals sprout like orange cosmos after a good rain. And just like that cheery, self- seeding landscape staple, they’re an excellent source of inexpensive, easy-to-grow delights.

Whether you’re new to Florida gardening, a veteran in search of novelty or a frugal shopper with a long holiday gift list, the tao of garden shopping is the plant fair.

If I haven’t yet sold you, add this: Professional growers and expert gardeners staff these sales. They know what they’re talking about and share tips freely. I’ve solved many a problem by asking a vendor who’s selling a healthy version of my sickly specimen.

That said, if you have a lot of questions, look for a booth labeled “Master Gardeners.” These expert volunteers from the University of Florida Extension make it their mission to help us succeed. For free. Bring a chomped leaf, a photo, a bug — they’ll help you figure it out.

You’ll have more fun if you go equipped:

• Because two hands don’t hold much, bring a rolling tote: a folding shopping cart, kids’ wagon or childless stroller works great.

• It may be fall, but think summer. A brimmed hat, sunblock and water will help you last a little longer so you can buy more plants!

• If you’re buying a new-to-you plant, record the name and care tips with a note pad and pen or your note-taking smartphone. (If vendors have detailed signs on their plants, I just snap a photo with my phone.) Memories can’t be trusted, I don’t care how old you are.

• • •

Searching for the great plants we read about can be frustrating. (Yes, I can hear the exasperated sighs in your emails! I feel your pain.) At plant sales like these, you can find those elusive holy grails and discover new ones.

At the very least, you’ll enjoy some fun garden time — no weeding required.
