Restio’s do best in open sunny positions with good air movement – they like the wind! Free draining soils with a PH of 7.5 and below are prefferable – thats neutral to acid. Being mostly from mediterranean climates they are well adapted to summer drought however, during long dry periods the plants will be greener and more lush with an occasional watering. They are not for boggy or water-logged soils.
Most are suitable for growing in pots, especially in their early years. Choose a free draining compost, we use a mixture of peat and bark, about 70/30. In pots keep plants moist at all times, they dislike drying out in containers. Watch out during frosty weather in winter as this can dry pots out very quickly. Occasional feeds of diluted liquid seem very benificial..Find more info on kelnanplants.com
