Propagation of Platanthera zeyheri (Sond.) Schltr.
Platanthera zeyheri (Sond.) Schltr., also known as the woodland white butterfly orchid, is typically propagated through seeds or by dividing mature plants.
Propagation through seeds
The seeds of Platanthera zeyheri should be collected when the capsules turn brown and start to split open. After harvesting, the seeds can be sown immediately or stored in a cool, dry place until the appropriate time arrives. Seeds can be germinated on a well-draining mix of peat and perlite, with optimal germination occurring at temperatures between 20-25°C. Germination can be slow, taking up to 3-4 months.
Propagation by division
Platanthera zeyheri can also be propagated by dividing the mature plants in the fall, before the first frost. One can lift the plant carefully from the ground, and divide the rhizomes into sections, ensuring that each section has at least one healthy shoot. The sections can then be replanted into prepared soil. It is essential to ensure that the rhizomes do not dry out during the division process.

Root rot: Root rot is a fungal disease that attacks the roots of Platanthera zeyheri. It is caused by overwatering or poorly-draining soil conditions. Symptoms can include yellowing and wilting of the leaves, as well as stunted or distorted growth. One way to manage root rot is to make sure the plant is not sitting in standing water, and to use a well-draining potting mix.
Virus: Viral diseases can be devastating to Platanthera zeyheri. Symptoms can include stunted growth, yellowing leaves, and distorted flowers.
