How often to water an orchid
Phalaenopsis
Spring–autumn 10 days
Winter 15 days
In a bright room, water your orchid about every 10 days from spring to autumn and every 15 days in winter. Check that the top of the soil is dry first.
By season and light
| Season | Bright spot | Lower light |
|---|---|---|
| Spring to autumn (Apr–Oct) | every 10 days | every 13 days |
| November and March | every 13 days | every 16 days |
| Winter (Dec–Feb) | every 15 days | every 20 days |
These are the starting intervals Trellis uses when you add an orchid. Growth slows in winter, so the interval is stretched 1.5× in Dec–Feb and 1.25× in November and March, and 1.3× in lower light (seasons are flipped in the Southern Hemisphere). Pot size and room temperature change things, so adjust to how fast the soil dries.

Seasonal notes
Winter
- Water less and keep it warm in winter
Tips for your orchid
- Silvery roots mean the orchid needs water
- Water the roots, not the crown or flowers
- After blooming, cut above a node — it may rebloom
- A clear pot lets you see the roots
