Expert tips
The key tip
Dicliptera squarrosa loves fertile soil and plenty of water in summer. Prune lightly after flowering (September) to remove tired stems.
The common mistake
Neglecting water in July-August causes flowers to drop, leaves to yellow, and the plant won't bounce back for the rest of the season.
The pro's trick
In May, before the plant starts flowering, pinch back young shoots to encourage branching and get a fuller, more floriferous shrub.
Care
Exposure
Place Dicliptera squarrosa in full sun to encourage abundant and generous flowering. It tolerates very sunny and bright locations well. Insufficient light can reduce flower production.
Watering
Water regularly to keep the soil moist but well-drained, particularly during summer flowering. Reduce watering in autumn and winter. Avoid letting the substrate dry out completely between waterings.
Soil
Prefer light, well-drained soil rich in organic matter. Potting mix for flowering plants mixed with coarse sand works perfectly. Soil that is too heavy may cause root asphyxiation.
Fertilizer
Apply a balanced, diluted fertilizer every 15 days or so during the growth and flowering period (May to September). Stop fertilizing in winter. Moderate feeding is sufficient; excess promotes foliage at the expense of flowers.
Pruning and maintenance
Pinch young stems regularly in spring to encourage bushier branching. After flowering ends, cut back spent stems. Light pruning after winter helps rejuvenate the plant.
Diseases and pests
Watch for aphids or whiteflies during warm periods. Excess stagnant moisture can lead to fungal diseases; ensure good air circulation. Remove diseased or damaged leaves as soon as they appear.
Did you know?
Dicliptera squarrosa belongs to the Acanthaceae family, renowned for its delicate and often two-lipped flowers. The name 'Dicliptera' literally means 'two closed lobes' in reference to the particular structure of its flowers. This tropical plant regularly attracts pollinating insects and brings an exotic touch to sunny gardens.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
