Germination of
Kalmia latifolia
. Mountain Laurel (Calico Bush) - Kalmia latifolia
Kalmia latifolia seeds require a cold stratification period in order to germinate. Start by mixing the seeds with moistened peat moss or vermiculite, and then seal them in a plastic bag or container. Place the bag or container in the refrigerator for 4-6 weeks, keeping the temperature between 32-40�F (0-5�C). After the stratification period, sow the seeds on the surface of a well-draining soil mix and cover them lightly with a thin layer of soil. Keep the soil moist and in a bright, warm location. The seeds should germinate within 1-2 months.
Some of plants may have very have specific germination requirements that may not be covered in these general instructions.
Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here. Germination times and germination temperatures are to be a guide only. Many factors can DRASTICALLY affect this.
It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
