Soil and substrate

For growing duranta, the optimal soil is light and well-drained. A mix of garden soil, peat, sand, and perlite works well. The approximate ratio is: 2 parts garden soil, 1 part peat, 1 part sand, and 1 part perlite. This mixture provides good drainage, preventing water stagnation, which is crucial for a plant prone to root rot due to excess moisture. You can also add some organic fertilizer to the soil to provide the plant with additional nutrients.

Duranta prefers soil with an acidic or neutral ph, so it is recommended to maintain the acidity at a level of 5.5-6.5. It’s important to monitor soil quality and change the substrate if necessary to ensure the plant has everything it needs for healthy growth and flowering.

Watering

Duranta requires moderate watering. In summer, during warm months, watering should be more frequent to keep the soil moist, but without over-watering. It’s best to water the plant when the top layer of soil is slightly dry. In the winter, watering is reduced as the plant is in a resting phase. It’s important to avoid water stagnation in the pot, as this can lead to root rot.

One sign of improper watering is yellowing and leaf drop. This can be due to either over-watering or under-watering. Regularly check the soil moisture and adjust watering according to the season.

Fertilizing and feeding

Duranta needs regular feeding, especially during periods of active growth and flowering. It’s best to use fertilizers high in phosphorus and potassium, as these promote good flowering and strengthen the root system. Complex liquid fertilizers can be used, applied once a month in spring and summer.

In winter, when growth slows down, the plant does not need feeding. Overfeeding should also be avoided as it can lead to salt buildup in the soil and worsen the plant's condition.

Propagation

Duranta can be propagated by both cuttings and seeds. Cutting is the most popular method. For this, cut young shoots about 10-15 cm long, remove the lower leaves, and root them in water or a soil mixture with added sand. Rooting usually takes 2-3 weeks at a temperature of 20-25°c. The cuttings should be regularly misted to maintain optimal humidity.

Propagating by seeds is a more complex process that requires patience and attention. Seeds should be sown in small containers with light, nutritious soil and kept moist. Seedlings begin to develop after a few weeks, but they require more time and attention to grow compared to cuttings.

Flowering

Duranta begins to flower in the warm season, usually during the summer months, and continues until autumn. The flowers are small and gathered in large panicles that can be purple, white, blue, or yellow, depending on the variety. Flowering is the main decorative feature of duranta, and during this period, the plant attracts attention with its vibrant and fragrant blooms.

The flowering period can be long if the plant receives enough light and warmth. However, if grown in a space with insufficient light, the flowering may be less abundant and shorter.

Seasonal features

In summer, duranta grows actively, increasing in size and often providing abundant blooms. It’s essential to maintain optimal conditions for growth during this time: adequate watering, feeding, and good lighting. In autumn, growth slows down, and the plant begins to prepare for a resting phase, reducing its need for nutrients and water.

In winter, duranta enters a dormant phase, and its care is minimized. Watering should be reduced, and feeding stopped. If necessary, the plant can be moved to a cooler place, where the temperature stays around 15°c.

Care features

Duranta is a relatively undemanding plant that doesn’t require complicated care. However, to achieve good decorative results, a few key rules should be followed. First, it’s important not to let water stagnate in the soil and to monitor light levels and temperature in the room.

Regularly check the plant for pests and diseases to prevent problems. It’s also important to periodically prune duranta to maintain its compact shape and stimulate new growth.

In addition, duranta should be regularly pruned to control its growth and maintain its attractive shape. The best time for pruning is in the spring or after flowering, removing dead or damaged stems. Regular repotting will help keep the plant healthy and provide space for growth.

Repotting

Duranta should be repotted annually or every two years to give it room to grow and refresh the soil. Choose pots that are slightly larger than the previous ones to allow the root system to develop. Ceramic or clay pots are good options as they allow the roots to breathe naturally and prevent water stagnation.

The best time to repot is early spring, when the plant begins active growth. This gives the plant time to adjust to the new pot and soil. It’s also useful to update the drainage layer at the bottom of the pot to avoid water stagnation.

Pruning and shaping the crown

To maintain duranta’s compact shape, regular pruning is necessary. It’s best to do this in the spring, before active growth begins, or immediately after flowering. Cut back old and weak stems, as well as those growing in unwanted directions.

If needed, the plant can be shaped into a shrub or even a small tree, depending on preferences and conditions. Pruning helps stimulate new growth and ensures more abundant blooming.

Possible problems and solutions

Duranta may face several issues, such as yellowing leaves, falling flowers, or poor growth. These symptoms can be due to improper watering, insufficient light, or a lack of nutrients. It’s important to properly diagnose the problem and adjust care, such as improving drainage, moving the plant to a brighter location, or feeding it.

If the plant suffers from diseases like powdery mildew or fungal infections, it should be treated with fungicides. It’s also crucial to monitor the roots and remove any damaged sections.

Pests

Duranta may be attacked by various pests, including spider mites, aphids, whiteflies, and scale insects. For prevention and control, it’s important to regularly inspect the plant and apply insecticides or natural protective methods, such as soapy water.

Improving growing conditions can also help reduce stress on the plant, making it less attractive to pests.
