Scientific name: maranta leuconeura (maranta's white string plant). Common name: prayer plant. Origin: native to tropical brazilian forests. Light: bright, indirect light throughout spring and summer; it will appreciate a splash of morning or evening sun in autumn and winter. If it isn't moving its leaves up and down often this probably means it's a bit too shaded. Water: allow the top quarter of the soil to dry out between waters; make sure to keep an eye on this, especially in brighter spots where the soil will dry out quicker. Humidity: likes high humidity, so will benefit from the introduction of a humidity tray and regular misting. Hose down the plant to keep it dust-free and keep an eye out for curling, browning leaves indicating low humidity. Soil: use a well-aerated soil mix which also retails moisture well to keep this plant happy; a mix of light components such as coir with moisture-retentive vermiculite or zeolite works well. Repot every two years in spring as the plant grows. Food: feed every four waters in the growing season, and reduce to every six in autumn and winter. Temperature: ideal temperature is 18-27°c. Sprouts top tips: keep an eye on your maranta's leaves for an indication of its health; yellow leaves signify overwatering and soggy soil whilst brown, crispy leaves indicate too little humidity.
