About Anthurium andraeanum 'Midori'

Anthurium andraeanum 'Midori' · also called Midori anthurium, green anthurium · tropical

'Midori' is a distinctive green-flowering Anthurium andraeanum hybrid whose heart-shaped spathes open a fresh apple-green rather than the usual red. An epiphytic tropical aroid, it blooms for weeks at a time and thrives indoors in warm, humid, brightly lit spots. The cool green bracts and glossy foliage give it a clean, modern look.

Ideal humidity: 50-70%

Watch for — Spathes turning brown or dull: Low humidity, draughts, or hard-water salts. Raise humidity, keep away from heat sources, and water with filtered or rainwater.

The watering schedule, season by season

Anthurium andraeanum 'Midori' grows on bark, not in soil — it wants its roots soaked then fully dried and exposed to air, never kept damp like a potted plant. The base rhythm for anthurium andraeanum 'midori' is when the top 2-3 cm of mix is dry, roughly every 5-7 days in growth, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: soak or dunk the roots/mount thoroughly about once a week, then let them dry almost completely before the next soak.
Autumn (slowing down): Autumn: lengthen the gap between soaks as light and growth taper off.
Winter (rest / dormancy): Winter: soak far less often — roughly every 2-3 weeks — and always let the roots dry fully in between.

Water deeply and let excess drain away; allow the surface to dry before watering again. The fleshy roots are rot-prone, so never leave the pot in standing water. Reduce frequency in the cooler, lower-light months.

How to tell anthurium andraeanum 'midori' needs water

A calendar is the worst way to water anthurium andraeanum 'midori'. Check the plant and the soil instead — for this species, look for these signals in order:

Roots turn silvery-grey or chalky instead of green/plump.
The mount or bark medium is bone dry and light.
Leaves or pseudobulbs look slightly wrinkled or less rigid.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering anthurium andraeanum 'midori' for a day is almost always safer than over-watering it.

Overwatering vs underwatering anthurium andraeanum 'midori'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For anthurium andraeanum 'midori' specifically:

Signs you are overwatering

Mushy, brown, hollow roots that have stayed wet too long.
Yellowing, soft leaves at the base.
A persistently wet, never-drying medium.

Signs you are underwatering

Leaves go limp, leathery or accordion-pleated; roots stay grey for long stretches.
Shrivelling pseudobulbs or curling leaves.

Treating anthurium andraeanum 'midori' like a normal houseplant — watering little and often into bark or moss that never dries — suffocates and rots the roots. Soak hard, then let it dry out.

Water quality notes

Rainwater or filtered water is best for anthurium andraeanum 'midori'; many epiphytes are sensitive to softened water and tap-water minerals.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For anthurium andraeanum 'midori', the levers that matter most are:

Air movement matters as much as water — roots must dry between soaks to avoid rot.
A bark or mounted medium dries far faster than moss, so the wetter the medium, the longer you wait.
In high humidity you can soak less often; in dry heated rooms, more often but still let it dry.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of anthurium andraeanum 'midori'.
