watering
Water this plant species once or twice a week, making sure the soil is kept moist through consistent monitoring of the top 2-3 inches of the soil tube. Apply enough water so that there is some visible draining at the bottom of the pot. An even deep-soaking of the soil is essential to ensure that the plant is adequately hydrated. It is important to reduce the amount of water given during periods of cooler temperatures. Madagascar periwinkle should not be waterlogged; if you notice water standing at the top of the pot, reduce the quantity of water given. Overwatering can easily lead to root rot.
sunlight
The Madagascar periwinkle (Catharanthus roseus) is a tropical annual plant that thrives in sunny conditions. It requires 6 to 8 hours of direct sunlight each day. Full sun is best early in the morning and late in the afternoon, when the sun's rays are not too harsh. Place the periwinkle in an area with dappled shade during peak sun hours. With this combination of full and partial sun, the plant can meet its need for strong light but avoid scorching from peak light intensity.
pruning
Pruning Madagascar periwinkle (Catharanthus roseus) is a relatively simple process and should be done as necessary for the health of the plant. Prune the spent flowers frequently, as soon as they start to wilt (monthly in most areas). To encourage new growth, prune back long stems close to their base as needed. Pruning can be done just before the plant starts to bloom in late summer or early fall.
