Morning Glories are Fine; Bindweed is Not!
I recently bought two packs of morning glory seeds. After reading all these post I was confused as to whether I should plant or through them in the trash.
If you have a nemesis or rival you could plant them at their house and see if you’d want them after a season or two.
The morning glory sold in the nursery catalogs is an annual and is fine, I believe.
For melons, squash, and other vine crops (Cucumbers, tomatoes, etc), I lay clear plastic or black plastic around the base of the plants. (Throw dirt on the plastic to hold it down.) This reduces bindweed 100% if you do it right. Yes, the bindweed comes back next year. For my strawberry patch I dip a small paintbrush in Roundup (3 times the normal ratio), and “paint” the bindweed between the rows. I think when you increase the dosage from 3 oz per gallon to 9 oz per gallon it knocks the plant back farther, and it takes longer to return.
Actually John, we have really high calcium soils here in KS and MO. Lots of limestone. Missouri is ranked as the number 3 state in cement production in the U.S. (cement is basically ground cooked limestone). My soil tested very high in Ca. I can’t remember the numbers off hand, but it was very high. Hasn’t slowed bindweed that I can tell. If it’s not fought, it will eventually make a solid thick carpet. Then spread the seeds more by wind the next year to carpet another area.
