Help rescue over-watered houseplant - species unknown

Question

can anyone tell me how to revive this plant please? I'm unsure of the species. I'm pretty sure I over-watered it. The bottom leaves started turning yellow. I repotted and removed as much as the water logged soil as possible before putting the roots back in to fresh compost. Since then however the leaves have gone very dark. Please help]1

Answer 1

This plant is an anthurium and is described in more detail here. I find they are quite happy in a small pot and even flower a little more. From the picture it looks like

• the pot is too big
• the soil looks like pure peat
• the brown spots on the leaves remind me of damage due to low temperatures but are also likely to be overwatering

I recommend putting the plant in bright diffuse light. Do not fertilize until you see new growth. At this stage more repotting is not advisable so you need to water when the top half inch to inch of soil has dried out. Be sure the plant is not sitting in water.

Answer 2

If the pot you've moved it to doesn't have drainage holes, I'm afraid you need to repot into something which does. Do it carefully in an attempt to cause as little disruption to the plant's roots as possible. These plants like high humidity, so standing the pot on a wide tray full of pebbles kept half topped up with water will help with that, but the bottom of the pot should not be sitting in the water. If you use an ordinary tray or outer pot without pebbles for the plant, be sure to empty out any excess water 30 minutes after watering.

The soil it's growing in should never be allowed to dry out completely - they prefer slightly damp roots, but not waterlogged. Bright diffuse daylight means no direct sun, but bright daylight, by the way...

These aren't particularly easy houseplants to keep, in my own experience; mine was still reasonably healthy after the red bracts had died back, but I never managed to get it to produce those (with the spike of flowers) again. Yours may have been waterlogged in its previous pot or possibly too close to a draughty window and it got cold. Note they should not be placed near a heat source, such as a radiator; heated rooms during winter often means dry air, which they also dislike. Your plant may or may not recover; you can remove the leaf and stem of any leaves that go yellow as they fade.
