Temperature Requirements
This plant prefers warm and humid conditions. The ideal temperature range for the Basilicum polystachyon var. stereocladum to grow is between 20°C to 30°C (68°F to 86°F). At temperatures below 10°C (50°F) or above 35°C (95°F), the plant may not thrive and may even die. Protect the plant from frost during winter months.
Soil Requirements
Basilicum polystachyon var. stereocladum grows best in well-drained, fertile, and loamy soil with a pH range of 6.0 to 7.5. The soil should be rich in organic matter, such as compost or well-aged manure. Make sure the soil is moist but not waterlogged. Too much moisture can lead to root rot and eventually kill the plant. Adding a layer of mulch around the plant can help retain moisture in the soil.
Cultivation methods for Basilicum polystachyon (L.) Moench var. stereocladum Briq.
The cultivation of Basilicum polystachyon (L.) Moench var. stereocladum Briq. is not very different from that of other basil varieties. The plant prefers well-draining soil and warm conditions with plenty of sun. It can be grown both in pots and in garden beds.
If grown in a pot, ensure that the pot is at least 6 inches deep and 8 inches wide. The soil should be rich in organic matter and have a pH of between 6.0 and 7.5.
When planting in garden beds, ensure that the soil is well-draining and has been enriched with organic matter. The seedlings or cuttings should be planted at least 12 inches apart to allow for adequate air circulation.
Watering needs
Basilicum polystachyon (L.) Moench var. stereocladum Briq. requires regular and consistent watering to thrive. The soil should not be allowed to dry out completely, but at the same time, waterlogging should be avoided.
It is recommended to water the plant deeply once or twice a week, depending on the weather conditions. The frequency can be increased in hotter and drier conditions.
Fertilization
A well-fertilized plant will produce a higher yield and be more resistant to pests and diseases. Basilicum polystachyon (L.) Moench var. stereocladum Briq. requires regular fertilization throughout the growing season.
A balanced fertilizer with an N-P-K ratio of 10-10-10 is recommended. The fertilizer should be applied every two to four weeks, depending on the soil fertility and growth rate of the plant.
Pruning
Pruning is essential for the healthy growth of Basilicum polystachyon (L.) Moench var. stereocladum Briq. Regular pruning helps to prevent the plant from becoming too bushy and promotes the growth of new shoots.
The plant should be pruned regularly to maintain its shape and prevent it from becoming too tall and leggy. The pruning should be done by pinching off the stem tips, which will encourage branching and promote denser growth.
Propagation of Basilicum polystachyon var. stereocladum
Basilicum polystachyon var. stereocladum Briq., commonly known as Greek basil, is a small-statured, annual herbaceous plant with dense foliage and tiny purple flowers. Propagating this plant is relatively easy and can be done through various means.
Seed propagation
Seed propagation is the most common method for propagating Basilicum polystachyon var. stereocladum. The seeds are small and should be sown in a well-draining soil mix. Sowing can be done directly in the ground or in containers, which should be kept in a warm, sheltered area with consistent moisture until germination occurs. Germination usually takes around one to two weeks and occurs when the soil temperature is between 20-25°C.
Vegetative propagation
Basilicum polystachyon var. stereocladum can also be propagated through vegetative means, such as cuttings. To do so, take cuttings from healthy stems with at least two nodes and remove the leaves from the bottom node. Dip the cut end in rooting hormone and plant in a well-draining soil mix. The cuttings should be kept in a warm and humid environment until roots start to grow, after which they can be gradually exposed to the outside elements.
Division
Basilicum polystachyon var. stereocladum can also be propagated through division. To do so, carefully divide the roots of an established plant, ensuring that each division has healthy roots and foliage. Plant each division into its own pot or in the ground and keep it well-watered until it takes root.
