Tanacetum potentilloides var. nitrophilum requires full sun or partial shade. It grows well in areas with bright sunlight for at least 6 hours a day. In shady areas, the plant may grow with elongated internodes and become leggy.
Temperature Requirements
This plant can tolerate a wide range of temperatures. It grows well in locations with mild temperatures, ranging from 14°C to 25°C. However, it can also do well in areas with high temperatures, although it requires proper irrigation to prevent it from drying out.
Soil Requirements
Tanacetum potentilloides var. nitrophilum thrives well in well-drained fertile soils. The plant prefers soils that are rich in organic matter and can hold moisture well. Sandy to loam soils with a pH of 6.0 to 7.5 are ideal for its growth. Additionally, this plant is nitrophilic meaning it requires soil rich in nitrogen for its optimal growth.
Cultivation methods
The plant Tanacetum potentilloides (Gray) Gray var. nitrophilum Cronq. is a perennial herb that is relatively easy to cultivate. It prefers well-draining soil with a pH range of 6.0 to 7.5, but it can also grow in poor soils. It can be propagated via seeds or division. For seeds, sow them in spring or fall, and cover with a thin layer of soil. For division, separate the rooted clumps and replant them in a new location.
Watering needs
It is essential to keep the soil moist, but not waterlogged. Water the plants regularly during the growing season, and reduce the frequency during the winter months. Ensure that the plant receives enough water during the hot and dry spells to prevent wilting. Moreover, avoid watering from overhead as this can contribute to fungal diseases.
Fertilization
Tanacetum potentilloides (Gray) Gray var. nitrophilum Cronq. benefits from feeding to encourage healthy growth. Use a balanced fertilizer during the growing season, and follow the instructions on the label for the correct dosage and frequency. Apply the fertilizer evenly around the base of the plant to avoid burning the foliage.
Pruning
Regular pruning is required to maintain the shape and size of the plant. Cut back the plant by two-thirds in late fall to remove any dead or damaged stems. In spring, trim back any undesirable growth to encourage bushy growth. Deadhead the plant regularly to prolong the bloom time and maintain a tidy appearance.
Propagation of Tanacetum potentilloides var. nitrophilum
The propagation of Tanacetum potentilloides var. nitrophilum can be achieved through either seeds or vegetative means such as stem cuttings.
Seed Propagation
The seeds of Tanacetum potentilloides var. nitrophilum can be directly sown into the ground in the fall or early spring. It is recommended to sow them on fertile, well-drained soil. The seeds should be scattered thinly and covered with a fine layer of soil. The germination of the seeds usually takes about 2-3 weeks. Once the seedlings are about 2 inches tall, they can be thinned out to allow for proper spacing.
Vegetative Propagation
Vegetative propagation of Tanacetum potentilloides var. nitrophilum can be done by taking stem cuttings during the growing season. The cuttings should be approximately 4-6 inches long and taken from healthy plants. The lower leaves should be removed and the cuttings should be inserted into well-draining soil. It is important to keep the soil moist and provide partial shade to prevent the cuttings from drying out. The cuttings should root within 4-6 weeks and can then be transplanted into their permanent location.
