Environmental conditions

Light. The Marvel-of-peru prefers sunny places, where it can benefit from sunlight for at least 6 hours a day. It can also tolerate partial shade, but in these conditions it is likely to no longer bloom profusely.

Temperature. It prefers higher temperatures. In areas with a colder climate, they are grown as annual plants, which die with the drop in temperatures and the appearance of frost. However, after flowering, in autumn, the tuberous roots can be removed from the soil and stored in a cool and dark place. They will be planted in the spring, once the temperatures start to rise. In areas with a warmer climate, the tuberous roots can remain in the soil during the winter.

Soil. It does not have high demands in terms of soil. It grows well on a fertile, clayey, well-drained soil. The soil can have a neutral-slightly acidic pH.

Marvel-of-peru – care

Watering. It will be done regularly, letting the soil dry slightly on the surface before watering again. Excessive watering and a permanently wet soil will lead to root rot. Plants grown in pots will be watered more often than those grown directly in the ground.

Fertilizing. In order to grow properly and to bloom, the regular fertilizing of the plants with balanced fertilizers is recommended. Special fertilizers for flowering plants can be used.
