Temperature Requirements
This plant thrives in warm temperatures between 20°C and 28°C during the day and 12°C to 16°C at night. It is not frost-tolerant and cannot withstand temperatures below 5-10 °C. Therefore, it is essential to grow it in a warm environment, especially during the winter season.
Soil Requirements
Lagarinthus navicularis E.Mey. requires a well-draining soil type with a pH range of 5.5 to 6.5. The soil should be rich in nutrients and organic matter to promote growth and flowering. A sandy, loamy soil mixture with equal parts of peat moss and perlite is ideal for this plant. It is also important to ensure that the soil moisture is consistent but not waterlogged, as over-watering can lead to root rot.
Cultivation Methods for Lagarinthus navicularis E.Mey.
Lagarinthus navicularis E.Mey, a perennial plant, thrives in full sun to partial shade. It requires well-drained, fertile soil that is moist but not water-logged. It can grow in various soil types, including sandy, loamy, and clay soils, as long as the soil is well-draining.
It can be grown from seeds or cuttings, with the best planting season being spring. The plant can be propagated by division during early spring, with the new plants requiring to be established before the onset of winter.
Watering Needs for Lagarinthus navicularis E.Mey.
Lagarinthus navicularis E.Mey requires moderate watering during the growing season. The plant should be watered regularly, especially during dry spells, to keep the soil moist but not waterlogged. Overwatering can lead to root rot, which may be fatal to the plant. The plant can tolerate mild drought, so it is necessary to avoid excessive watering.
Fertilization of Lagarinthus navicularis E.Mey.
It is recommended to fertilize Lagarinthus navicularis E.Mey with a balanced fertilizer during the growing season to promote healthy growth and flowering. Fertilization should be done in early spring, with one more application in mid-summer, using granular or liquid fertilizers. Too much nitrogen can result in rapid, leggy growth and reduced flowering, so it is essential to avoid excessive fertilization.
Pruning of Lagarinthus navicularis E.Mey.
Lagarinthus navicularis E.Mey requires minimal pruning to remain healthy and attractive. Deadheading of spent flowers will encourage the plant to produce more blooms. If necessary, the plant can be pruned lightly in early spring, removing any damaged or diseased stems. The plant may also benefit from a light pruning in mid-summer to rejuvenate the growth and promote more blooms.
Propagation of Lagarinthus navicularis E.Mey.
Lagarinthus navicularis E.Mey. can be propagated by various methods:
Seed Propagation
Seeds of Lagarinthus navicularis E.Mey. can be collected from the plant directly after the flowering period. The collected seeds should be cleaned and dried properly. They can be sown in a well-prepared seedbed or potting mix and covered with a thin layer of soil. Germination usually occurs within 2-3 weeks, and the seedlings can be transplanted to their permanent location after 6-8 weeks.
Cuttings Propagation
The plant can also be propagated through stem cuttings. Cuttings should be taken in the spring or summer from softwood stems. The cuttings should be around 10-15 cm long and have at least two pairs of leaves. Remove the lower leaves and dip the cuttings in rooting hormone and plant them in a potting mix. Place the pot in a warm, bright location, keeping the soil moist until rooting occurs. Once the roots have formed, the cuttings can be transplanted to their permanent location.
Division Propagation
The plant can also be propagated by dividing the root clumps. The best time to do this is in the spring or fall, when the plant is not blooming. Dig up the clump and gently divide it into smaller clumps, each with a few roots and shoots attached. Replant the clumps in a well-draining soil mix and keep the soil evenly moist until they establish.
