How to grow Parochetus

When growing from seed it is best to start to grow Shamrock pea indoors. The process should be started about eight weeks before they are due to be planted outdoors. The seeds should first be soaked for a day in warm water then germinated at 10 degrees centigrade. It should take about one to three months for Parochetus seeds to germinate.

Once ready transplant the seedlings into the garden about 30 to 40 cm apart either in spring or autumn. They are able to grow in either a sunny or lightly shaded area that has good drainage. Ideally the soil that plants grow in should be poor, gritty and moist as this will produce more flowers.

Caring for Shamrock pea - Parochetus

Shamrock pea and other Parochetus are very easy to look after but should be watered regularly to keep the soil that it grows in moist. If you require more Parochetus plants, then they can be propagated by division or taking cuttings in the autumn or at the start of spring.
