Perilla plant species are able to grow well in both sunny and lightly shaded areas. Ideally the soil should be fairly dry.
If growing Perilla species in the greenhouse first, then start the process about 2 to 3 months in advance. The seeds should take from two to four weeks to germinate in the light at 18 to 24°C.
Once ready transplant the young Perilla seedlings to about 30 to 35 cm apart (after the last frost).
Perilla plants are easy to grow; as soon as they reach about 15 cm pinch the growing tips back to encourage bushiness.
The plants can take over the garden so you may like to deadhead the flowers before the seeds have a chance to set.
If you require more Perilla plants then propagation can be had by taking cuttings, or they can be easily grown from seed.
