Plant marsh orchid with the finger tubers about two to three inches deep, buds facing up.
Set the finger tubers about two to three inches deep, buds up
| Factor | Recommended | Avoid |
|---|---|---|
| When | Fall while the plant is dormant, or as shoots start in spring | Planting a dried-out tuber in midsummer heat |
| Depth | Top of the tuber mass about two to three inches down; a bit deeper in a colder winter | Burying the tuber deep in a wet hole |
| Hole | Moist, draining soil; spread the finger roots, buds up | A vertical wad packed into standing water |
| Stock | A nursery tuber or a crowded clump you already own | A wild-dug plant from a meadow |
Plant nursery tubers, not wild-dug plants. Set the top of the root mass about two to three inches below the soil, with the growing tip facing up, then water to settle. [1] marsh orchid and common spotted orchid take that same shallow set.
How deep do I plant marsh orchid?
Set the top of the tuber mass about two to three inches down, buds up. Go a little deeper in a colder winter. Planting in a wet hole rots the tuber.
How to plant a marsh orchid
Plant one nursery plant at a time in a prepared hole, with the buds facing up, then keep the new hole moist.
- Confirm a marsh kind, a spotted orchid, or Madeira orchid on the tag. If the tag is only a shop name, match it on Types of Marsh Orchid.
- Plant in fall while the plant is dormant, or as new shoots start in spring. Do not let a bare tuber dry on the bench. [2]
- Clear perennial weeds. Loosen moist soil that still drains. Do not plant into a puddle.
- Set the finger tubers with the buds facing up. Cover so the top of the mass sits about two to three inches down — about three to four inches in a colder winter, or the same depth as the nursery pot. [3]
- Leave room for the new fingers that replace the old tuber each year. Water to settle. After planting, sun, moisture, and rest are on How to Grow Marsh Orchid. Buy nursery stock — do not plant a wild-dug tuber.
When should I plant marsh orchid?
Fall while it is dormant, or as shoots start in spring. Do not plant a dried-out tuber in hot weather.
Twist a new tuber off after bloom
Dividing uses the same planting depth. After the flowers fade, lift the clump, shake the soil, and twist the new finger tuber off the old one. Replant the new tuber with the tip just under the soil, or wait until early spring. Tubers resent extra moves, so divide only a crowded clump. [4]
Can I divide marsh orchid?
Yes, after bloom or in early spring. Twist the new tuber off and replant at the same shallow depth. Do not split a small first-year plant.
If the tuber is sitting in a wet hole, lift it and reset it two to three inches deep in soil that drains.
FAQ
Can I start marsh orchid from seed?
Not as a home shortcut. The dust-fine seed needs a fungus to germinate. Buy a nursery tuber, or divide a mature clump.
Can I divide instead of planting a nursery plant?
Only if you already have a crowded clump. Twist the new tuber off after bloom and replant the same day. A first-year plant is not ready.
