Growing marshmallow from seed is indeed a relatively easy and rewarding process. While it may not be readily available in garden centers, ordering marshmallow seeds online is a convenient option. I have personally had success in planting marshmallow from seed and have found it to be a delightful addition to my garden.
To begin, it is important to understand that marshmallow seeds require a process called cold stratification. This mimics the natural cycle of the plant and helps break the seed’s dormancy. Cold stratification involves subjecting the seeds to a period of cold temperatures before planting.
Here is a step-by-step guide to successfully growing marshmallow from seed:
1. Obtaining marshmallow seeds: As mentioned earlier, marshmallow seeds may not be commonly found at local garden centers. However, they can be easily ordered online from reputable seed suppliers. Make sure to select a trusted source to ensure the quality of the seeds.
2. Cold stratification: After obtaining the marshmallow seeds, you will need to provide them with a period of cold stratification. This can be done by placing the seeds in a damp paper towel or in a sealed plastic bag with moistened peat moss. Store them in a refrigerator for about 4 to 6 weeks. This process helps to break the seed’s dormancy and promotes germination.
3. Preparing the planting site: While the seeds are undergoing cold stratification, it’s time to prepare the planting site. Marshmallow plants thrive in full sun to partial shade, so choose a location that receives at least 6 hours of direct sunlight daily. Ensure the soil is well-drained, rich in organic matter, and slightly acidic to neutral pH.
4. Planting the seeds: Once the cold stratification period is complete, it’s time to sow the seeds. You can directly sow the seeds outdoors in early spring after the danger of frost has passed. Alternatively, you can start the seeds indoors in pots or trays filled with seed-starting mix about 6 to 8 weeks before the last frost date. Lightly press the seeds into the soil or cover them with a thin layer of soil, as they require some light for germination.
5. Watering and care: Keep the soil consistently moist but not waterlogged during the germination period. Marshmallow seeds typically germinate within 2 to 3 weeks. Once the seedlings have emerged, thin them out to allow proper spacing, typically around 18 to 24 inches apart. Water the plants regularly, especially during dry periods, and mulch around them to retain moisture and suppress weeds.
6. Providing support: As marshmallow plants grow, they develop tall, slender stems that may benefit from some support. Consider using stakes or cages to help keep the plants upright and prevent them from bending or breaking under their weight.
7. Harvesting and enjoyment: Marshmallow plants usually reach maturity and start producing flowers in their second year. The lovely pink or white flowers are not only visually appealing but also attract bees and other beneficial pollinators to your garden. Once the flowers have bloomed and faded, small fruits resembling miniature cheese wheels may develop. These can be harvested and used for propagation or left to self-sow for the next season.
While marshmallow plants may not be commonly available in garden centers, they can be easily grown from seed with a little patience and care. By following the steps outlined above, you can enjoy the beauty and benefits of these lovely plants in your own garden.
