Water

Madagascar periwinkle does not need much water once established. A general rule is to water when the top inch of soil feels dry to the touch. If you're cultivating indoors, hydrate deeply and thoroughly until water drains out of the bottom of the pot.

Sunlight

Madagascar periwinkle loves full sun and can tolerate high temperatures. Place it in an area that receives at least 6 hours of direct sunlight per day for optimal growth and flowering. If grown indoors, place it near a bright south or west facing window and rotate the pot every week to ensure even growth and light exposure.

Soil

The plant prefers well-drained fertile soil that's not too acidic. A good potting mix for containers should be light and airy, with enough organic matter to improve drainage and aeration.

Fertilizer

The plant does not need much fertilizer, as it can grow in poor and nutrient-deficient soils. But to encourage lush foliage and blooms, you can apply a balanced fertilizer during the flowering season. If growing indoors, feed Madagascar periwinkle once a month from spring to fall with a liquid fertilizer diluted to half strength.

Pruning

It may benefit from occasional trimming to remove dead or damaged stems and leaves, shape the plant, encourage branching and bushiness. It's best to prune in early spring before new growth emerges.

Propagation

You can easily propagate the plant by seed, cutting, or division.

Thrives in

Warm and sunny conditions, with moderate to low water and fertilizer needs.

I'm an enthusiastic gardener. I learned the art of growing my own food using sustainable gardening techniques from my father, which I still find effective for healthy plant growth. Gardening has become one of my best hobbies ever since I realized its benefits beyond growing my own food. Through experimenting and connecting with nature, I've found gardening to be a therapeutic and relaxing practice.
