Growth Conditions for Tropaeolum Sessilifolium
The Tropaeolum Sessilifolium, also known as the growing nasturtium or Andean nasturtium, is a perennial plant that thrives well in cool temperature and moderate sunlight. It is a climbing vine that produces clusters of orange, red and yellow flowers along with unique-shaped dark green leaves.
Light Requirements
Tropaeolum Sessilifolium requires moderate sunlight, and it can tolerate partial shade, especially during hot summer months. However, to ensure optimal flower and foliage growth, it is essential to provide at least six hours of sunlight daily. Note that, the plant's growth rate, and the intensity of flower colours are impacted by variations in sunlight exposure.
Temperature Requirements
Tropaeolum Sessilifolium thrives well in temperatures between 7°C to 23°C. Ideally, the growth is optimal in a cool and temperate climate with a range of 10°C to 15°C. It grows well in USDA hardiness zones 7 to 10. The plant can tolerate light frosts, but if the winters are too cold, the plants will go dormant and may not flower in the following spring.
Soil Requirements
Andean nasturtium prefers moist, well-draining, fertile soil that is rich in organic matter. The soil pH should be slightly acidic, with a range of 6.5 to 7.5. It can tolerate slightly alkaline soils, but acidic soil is optimal for proper nutrient absorption and plant growth. Ensure to water the plant regularly, especially during the hot and dry summer months.
Cultivation Methods
Tropaeolum sessilifolium is native to the Andes of South America. It is best suited for cultivation in USDA hardiness zones 8a to 10b. The plant prefers cool temperatures, and it grows well in partial shade to full sun. It thrives in well-draining soils that are rich in organic matter. The plant can be grown from seeds or cuttings.
Watering Needs
When cultivating Tropaeolum sessilifolium, it is important to ensure that the soil is consistently moist but not waterlogged. Overwatering can lead to root rot, which can quickly kill the plant. The plant should be watered deeply once a week, and more frequently during hot, dry weather. During periods of heavy rain, it may be necessary to provide additional drainage to prevent water buildup around the roots.
Fertilization
Tropaeolum sessilifolium benefits from regular fertilization, especially during the growing season. A balanced fertilizer high in nitrogen, phosphorus, and potassium is ideal. The fertilizer can be applied every four to six weeks according to the manufacturer's instructions. Overfertilization should be avoided, as this can harm the plant.
Pruning
Tropaeolum sessilifolium requires minimal pruning. However, deadheading spent blooms can encourage further flowering. The plant can also be pruned lightly to control its size and shape. Pruning should be carried out in early spring before new growth begins. Any dead or damaged growth can be pruned at this time. Young plants should be pinched back to encourage bushier growth.
Propagation of Tropaeolum sessilifolium
Tropaeolum sessilifolium, commonly known as Peruvian nasturtium, is a beautiful trailing plant that produces delicate red-orange flowers. It is easy to propagate and can be done through various methods.
Propagation through seeds
The easiest and most common method of propagating Tropaeolum sessilifolium is through seeds. The plant produces seeds at the end of the growing season, which can be collected and stored until the next planting season. Sow the seeds in well-draining soil at a depth of 1 cm and keep them moist. Germination typically occurs within a week to ten days. Once the seedlings have developed two to three sets of true leaves, they can be transplanted into larger containers or directly into the garden bed.
Propagation through stem cuttings
Tropaeolum sessilifolium can also be propagated through stem cuttings. Take 7-10 cm long cuttings from the healthy stems of the plant, making sure to remove any leaves from the bottom two-thirds of the stem. Dip the cut end in rooting hormone and plant it in a pot or directly into the soil. Keep the soil moist and place the pot or planted cutting in a bright, shaded area until roots have formed. This typically takes 2-3 weeks.
Propagation through division
Tropaeolum sessilifolium is a creeping plant that forms clumps and can easily be propagated through division. Divide the plant in early spring before the growing season begins. Use a sharp, sterile knife to cut through the roots and separate the plant into two or more sections. Plant these sections in well-draining soil and water them thoroughly. Keep the plants moist until they have established themselves in their new location.
Overall, Tropaeolum sessilifolium is an easy plant to propagate and can be done through various methods, providing you with a beautiful and vibrant addition to your garden.
