Cultivation Methods for Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush.
Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush. can be propagated from seed or by stem cuttings. When growing from seeds, it is best to sow them in trays or pots filled with a well-draining potting mix. Keep the soil moist and place the tray in a well-lit area. When the seedlings are large enough to handle, transplant them into individual pots.
If you choose to propagate by stem cuttings, take cuttings from healthy, mature plants in the spring or early summer. Dip the cut end of the stem into rooting hormone and insert it into the potting mix. Keep the soil moist and maintain high humidity by covering the pot with a plastic bag until the cutting has rooted.
Watering Needs for Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush.
Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush. requires moderate watering. Water the plant when the top inch of soil feels dry to the touch. Overwatering can lead to root rot, so be sure to avoid letting the soil become waterlogged. During hot, dry weather, you may need to water the plant more frequently.
Fertilization for Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush.
During the growing season, you can feed Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush. with a balanced, water-soluble fertilizer once every month. Be sure to follow the instructions on the fertilizer package, as over-fertilization can cause damage to the plant. During the winter months, suspend fertilizer application as the plant's growth slows down.
Pruning Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush.
Pruning is not necessary for Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush., but if you want to shape the plant or help it to produce more flowers, you can pinch out the growing tips of the stems.

Propagation of Drymaria cordata var. pacifica:
Drymaria cordata var. pacifica can be propagated through different methods including seed propagation and vegetative propagation.
Propagation by Seeds:
The most common method of propagation for Drymaria cordata var. pacifica is by seed. Seeds should be sown in a sterilized soil mixture composed of peat moss, vermiculite, and perlite in equal parts. The seeds should be lightly covered and kept moist in a warm area with high humidity, preferably in a greenhouse. Germination may take up to a few weeks or even months. Once the seedlings are large enough, they should be transplanted into individual pots or ground beds.
Propagation by Vegetative Cuttings:
Drymaria cordata var. pacifica can also be propagated through vegetative cuttings. Take stem or leaf cuttings from a healthy plant, making sure to cut right below a node. Dip the cuttings in rooting hormone and place them in a well-draining soil mix. Keep the soil moist and provide high humidity by covering the cuttings with a plastic bag or by placing them in a propagation tray. After a few weeks, the cuttings should show signs of new growth. Once the roots are established, the new plants can be transplanted into individual pots or ground beds.
Disease and Pest Management for Drymaria cordata (L.) Willd. ex Roem. & Schult. var. pacifica Mizush.
