Q.Horse Tail Reed Dying
I have horse tail reed planted in three self watering pots in an uncovered area that gets full sun. They were doing very well but over the last two weeks all three plants started showing signs of distress. The leaves are turning yellow and brittle and dying out. One plant is worse than the other two but all showing signs of distress. I like in a tropical climate. The plants get full sun and I water them regularly. Help!!!!

There may be a salt buildup or excess fertilizer. It's best to use compost as a fertilizer rather than liquid or time release. Also, make sure they haven't gotten too crowded in the pots. Since they prefer a moist site, I wouldn't think it is overwatered. I would remove the lower watering bin and flush out the upper container for salts and fertilizer per the instructions below. Also, remove any browning stems.
