Well, It happened yet again. ! My potted Anise Hyssop plant -- which was lush, green and beautiful and well-flowered -- has turned brown and died. All the leaves and stems of the plant have turned brown, and it appears to be deceased. This same phenomenon happened last year with Anise Hyssop -- growing great, lush and green, lovely flowers, then seemingly suddenly, all plant parts turned brown. (By suddenly, I mean in several days to one week.) The plant has been growing in a med-large terra cotta pot in the garden, surrounded by other potted herbs and plants (which are all doing just fine). Is there a fungus or rust that is attacking the plant? Am I doing something wrong? I did plant the new plant in the same pot I had used for the Anise Hyssop last year, but had added fresh new potting mix and organic fertilizer as I usually do. The plant gets full sun for about 5 or 6 hours, then partial shade. I haven't checked the roots yet, but will. Maybe the heat of the pot is killing the roots -- but that seems so far fetched? Has anyone else experienced this problem? Is it because of all the rain we've been having here on the East Coast this Spring? The browning-out seemed to happen so suddenly, and is a repeat of what happened last year. Any help, suggestions, appreciated. Thanks !

The question that you asked regarding too much rain... Pretty much went along with my own thoughts reading your post.
I was wondering how much you watered... As at my house, they seem to do fine in the bottomless white sand... In the drought, without a drop of supplemental water.
Just out of curiosity...
Can you grow rosemary?

I have the same thing happen with lavender here. Haven't even tried any Hyssop because the lavender hardly ever makes it through the rainy season unless I keep it under the overhang of the house and then it gets no sun.

They love dry conditions and a gritty, fast drying soil would be my best recommendation if you want to try again. Mix a whole bunch of Perlite in with your potting soil and try again with that mix.

I'm sure it was the heavy rain that killed the plants, coupled with too moisture-retentive soil. Btw beware of "Moisture Control" potting soil. It's fine if you live in the desert, but anywhere that has humidity, it just stays wet all the time and kills plants right and left! The little moisture gel granules suck water out of the air and keep the soil so wet it's amazing. My gingers and cannas love it, but they can live in a pond and be happy. You can also use it indoors, (hey, it will probably help to de-humidify your house!) and anywhere you have low humidity.

I have an anise hyssop in a pot and it hates to get dry. According to several articles I've seen, including the below, it likes moist but well-drained soil. A terra cotta pot will dry out faster than a plastic one. Some of the places it grows naturally are beside lakes and rivers and in ditches. Quoting from the below: "The pH should be 6 - 6.5. It requires lots of moisture, and wilts if it is too hot."
