What I consider the utility area of the garden includes the rain barrels, the compost tumbler, access to the rain gauge and storage of a few miscellaneous items with potential for future garden projects (chunks of concrete, old wooden gates, some black edging, bags of mulch, etc.) This area has also become home to mystery plants.
I had a few mystery plants last year. I didn't know what they were. I left them hoping they were the local wild blackberries which are popular for pastries. When the mystery plants didn't produce blackberries, I forgot about them. My sunflowers and morning glories took over the area.
This spring, I noticed more of these mystery plants sprouting. They're spreading.
In the path.
By the morning glory trellis.
By the fence.
By the hawthorne tree.
And, numerous other places.
"Oh no," I thought. "What am I dealing with here?"
I searched online with no luck. I took a sample of the mystery plants to our local horticulture agent. She was stumped, and took the mystery plants to the nearby agriculture experiment station. Someone there identified the mystery plants as mirabilis nyctaginea or wild four o'clock. After some searching online, I found these sites with good information:
Wild four o'clocks can be aggressive and are considered a weed by some. I have decided that I'd like to control them, but want to keep some near the fence.
The last link above had the following information:
"The extensive root system and the waxy covering on the leaves hamper the effectiveness of herbicides."
Good to know that before I waste a lot of time trying to spray.
"Hand pulling is not recommended because the stems break at the crown, the roots are strongly branched, and broken root pieces will produce sprouting."
That explains why it's coming up in bunches. I tried to pull out some of the plants.
"Small infestations can be spaded, or dug up."
I don't think I want to dig in that area. Too rocky.
"Repeated mowing or cultivation will prevent seed production to lower the seed bank, and eventually the plant will die from loss of nutrient reserves stored in the root."
This is information I can use. My plan is to cut down the plants I don't want to the ground, and try to dead head the flowers of the plants I want before they produce seed. We'll see how this works out.
