Purple heart plants are breaking my heart


This is a plea for help.

When I first planted purple heart (or purple queen) in my garden, I was thrilled with the results. It spread very quickly, which was great for filling in the high-profile spots where I’d put it. And it looked beautiful.

I’ve had purple heart in pots before, and I know the stems can break off easily. But it grows so fast, that not really a problem.

Now that I have it in the ground in several places, though, I’ve noticed that it’s looking pretty ragged. Something is chewing the leaves – leaving little holes and ugly rough edges.

The University of Florida’s IFAS Extension Web site (http://www.ifas.ufl.edu), says there are “no pests or diseases of major concern” for purple heart, although “mites and chewing insects may occasionally cause injury.” This doesn’t match up to what my plants look like.

I’m wondering if they’re more susceptible if they get too much sun, because the plants in the sunnier part of the garden look the worst.

I could trim them back and see what happens, but I’m afraid the plants will just get eaten all over again.

I hate to spray if I don’t have to. Any thoughts?

I’m in total awe, Kim, that you’re having a problem with a plant I’ve had no problem with. Will wonders never cease?
I’ll be interested to see if it’s slugs. The bites look too little to be lubbers. (Ben ran over one on the way down here to the Keys. We cheered.)
  They sell Sluggo at Shell’s Feed on Nebraska, just north of Busch.

Thanks, Rick.

I don’t see too many snails in my yard, so I’m not sure if that’s it or not. But it sure couldn’t hurt to try the beer trick, if only to see if that’s the problem.

I do plan to fertilize, as well, just to help them brighten up and get stronger, so they can fight off whatever’s bugging them.

Do you know if they sell Sluggo at Home Depot or Lowe’s? A co-worker was telling me the other day that slugs are getting to his peppers—munching on the tops.

Could it be slugs or snails feeding at night? Do the old beer trick. Put beer in a jar lid where they can crawl in and drown. Also Sluggo is an organic bait that is primarily iron phosphate and lethal only to slugs and snails. (pet safe) It breaks down into iron and phosphate which are both absorbed by plants. Beyond that I would try 2 oz of timed release fertilizer per plant and pray for rain. No need to cut them back as they should be good as new in no time, especially with this heat and the full sun placement. Go Purple. Right Plant-Right Place!

About Us:

Kim's a Want It Now (WIN): Everything pretty, everything now.

Penny's a Nurture And Hold (NAH): Nah, I won't pull that out yet, it's still got a green shoot.

Kim will resort to full-spectrum insecticides in desperate situations, and believes it's her duty and right to buy new plants every weekend.

Penny likes dragonflies, lady bugs and new stuff only after weeding, pruning and fertilizing.

Both advocate Plant Choice (SOMEthing besides crotons. Please!), lots of color and low maintenance.

We don't agree on everything, but we're smart enough to learn from each other - and from you.
