Overall, Selago hispida L.f. var. nana Choisy is a delicate plant that requires specific growth conditions to thrive. The above-mentioned conditions, including light, temperature, soil, and water requirements, are necessary for ensuring that the Dwarf Marsh Felwort grows well and healthy.
Cultivation Methods
Selago hispida L.f. var. nana Choisy can be cultivated indoors or outdoors, depending on the climate. It is a hardy plant that can withstand occasional neglect and still thrive. For indoor cultivation, choose a pot that will allow the plant to grow to its full potential. A well-draining soil mix is essential to prevent waterlogging, which can lead to root rot. The plant prefers neutral to slightly acidic soil, with a pH level between 6.0 and 7.0. Place the plant in a location that receives bright, indirect light.
If you're growing Selago hispida L.f. var. nana Choisy outdoors, choose a spot that receives partial shade or filtered sun. The plant prefers well-draining soil and will not tolerate waterlogged conditions. If you live in an area with harsh winters, consider planting the Selago hispida L.f. var. nana Choisy in a container and bringing it indoors during the cooler months.
Watering Needs
It's best to keep the soil of the Selago hispida L.f. var. nana Choisy evenly moist but not waterlogged. Water the plant when the top inch of soil feels dry to the touch. Use room-temperature, filtered water when watering the plant and avoid getting water on the leaves. Overwatering can lead to root rot, so err on the side of underwatering rather than overwatering.
Fertilization
Selago hispida L.f. var. nana Choisy benefits from occasional fertilization to promote healthy growth. Use a general-purpose fertilizer once per month during the growing season, which typically runs from spring to autumn. Follow the instructions on the label, as applying too much fertilizer can damage the plant. Avoid fertilizing during the winter months, as the plant's growth slows down during this time.
Pruning
Pruning is not usually necessary for Selago hispida L.f. var. nana Choisy, as it maintains a neat, compact shape on its own. However, if the plant becomes leggy or overgrown, you can trim back the stems to encourage bushier growth. Do this in the spring before new growth starts. Use a clean, sharp pair of scissors or pruning shears and cut just above a leaf node. Dispose of the trimmed material appropriately.
