Q. Spearmint Plant

I am trying to grow spearmint plants inside in a small pot. I bought the plants at a grocery store. The leaves are drying up and turning brown even though they are watered twice a week. I see small gnats flying on them. What is wrong and how do correct it?

It could be dry in the center, in which case you could try soaking the pot in water. However, your problem could also be due to mint wilt (otherwise known as verticillium wilt), a fungal infection in the soil. While there is no treatment, you could try fertilizing to strengthen plants or repotting with a fresh, clean potting soil, inspecting the roots prior to replanting. Discard any dead or dying plants.

Q. Spearmint Plants and Effect on Growth of Other Plants

I have a patch of spearmint plants growing. If I pull them up and plant some vegetable plants there, will there be any problems getting them to grow there? I planted some squash plants there last year and they just died.

First, you'll want to make sure that all the spearmint has been removed, as these plants are somewhat invasive. Since you have had problems in the past with squash, you may want to get the soil tested to find out what nutrients may be missing in the soil, as well as the pH level. Once you have done this, you can correct any issues.

Q. Harvesting Spearmint

What is the correct way to harvest spearmint? I have seen references to sprigs, stems, etc. How do I tell the difference of each, and what is best way to harvest (i. e. pluck leaves, cut sprigs or stems) and how far down? I get plants (in large pot) to grow nicely, only to have the plant slowly die once I start harvesting. I live in south Florida where we have hot to warm weather usually 12 months a year.

Sprigs and stems are essentially the same thing. Typically you would harvest it like you were giving the plant a haircut. Simply cut off what you think you need.

It sounds like the plant may be dying after harvest due to disease getting in the open wounds. Trim only with very clean scissors and shears. You can wipe them off with rubbing alcohol even to kill anything that may be on the blade that could hurt the plant. Then, after you harvest, provide a little more water to the plant so that it is less stressed and can fight off disease better.

Q. Worms in My Mint Plants

I’m growing quite a bit of spearmint and recently noticed worms in the mint. I use the mint for tea. How can I get rid of the worms or any other pests that get there? Again, I plan on using the mint in tea, so I need a remedy that won’t get me sick.

Bacillus Thuringiensis (Bt) spray can quickly eradicate these leaf and stem-eating worms. It is a safe, biological insecticide. In fact, Bt a bacterium which is toxic to many moth and butterfly larvae (caterpillars) and will not harm the plants or other beneficial creatures, including us. In addition to using Bt in the garden for worms and caterpillar pests, you can try neem oil. Both are safe to use.

Q. growing spearmint

I bought a spearmint plant yesterday. It was in a bio-degradable pot so I stuck the whole thing in the ground. It is by a recently trimmed rose bush, but I can cut the roses back. How big will the mint get and how fast will it spread?

Q. herb cross pollination

I have chocolate mint and spearmint growing, one in the front yard and one in the backyard. I have heard that mint hybridizes easily. I was wondering if I took a cotton swab and cross pollinated the flowers, would they be like a mix between the two? It would only affect the seeds though right, not the original plants. I would collect the seeds. I also am growing basil, oregano, and sage. Would any of those cross?

Yes, you can do this and they would be a mix. And yes, it would only affect the seeds. Certainly worth it to try.

Basil will cross with other basils and oregano with oregano and sage with sages but not with each other.
