How to Grow Heliotrope and other Heliotropium Plants in the Garden
It is best to grow Heliotrope indoors first and then transplant later. They should be started about three months before they are due to be transplanted. Transplant outdoors a few weeks after the last frost of spring.
They take from a couple of days to six weeks to germinate at a temperature, of 21 to 24 degrees Centigrade (70 to 75°F).
Once Heliotropium plants are established, they can either be kept indoors in an area that receives plenty of sunlight, or transplanted outdoors into containers or the border. Use a spacing of about 40 to 50 cm (16 to 20 inches.
They prefer to grow in a sunny area of the garden with good drainage. Preferably locate in an east facing part of the garden, so that it gets shade in the afternoon. The soil should be rich.
Caring for Heliotrope (Heliotropium)
Once growing it is important to keep the soil that Heliotropium is growing in moist. Also provide a regular monthly feed.
Additionally, young Heliotropium plants should have their tips nipped to encourage bushy growth.
Once the flowering has finished, deadhead the flower to encourage further blooming.
If you require further heliotropes plant, then cuttings from either the root or stem can be taken in the autumn.
