Troubleshooting
Atlantic Monanthes problems — and how to fix them
Atlantic Monanthes (Monanthes atlantica) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot in humid, stagnant air
Dense rosettes trap moisture; in poor air circulation this promotes fungal crown rot. Grow in a well-ventilated spot and water at soil level rather than overhead.
Leaf drop in very dry conditions
Unlike most succulents, this species can lose inner rosette leaves if relative humidity drops very low. Grouping with other plants or using a pebble tray improves local humidity.
Root aphids
Small pot-grown specimens in dry conditions can harbour root aphids, which cause stunted growth and yellowing. Unpot, wash roots thoroughly, treat with a systemic insecticide, and repot in fresh mix.
