How to grow Stock, and other Matthiola Plants in the Garden

When growing stock outdoors from seeds, you should sow on the surface following the last frost of spring.

Alternatively in mild areas you can do autumn sowing of stock, this will result in spring blooms the following year.

Stock likes to grow in sunny areas of the garden that have good drainage, and a slightly alkaline and moist soil.

You can start to grow Stock indoors first. The annual and perennial varieties of Matthiola should be started about 7 or 8 weeks before the last frost of spring, whereas biennials stock should be started off in the summer.

It takes around one to three weeks for plants to germinate. Ideally the Matthiola Plants should be sown in vermiculite and watered from below. They will germinate if grown in the light at a temperature of 12 to 18 degrees centigrade (53 to 64°F).

Once ready, transplant annual and perennial stock out to the garden in mid spring or autumn. Transplant biennial stock in the autumn.

They should be spaced from 15 to 45 cm (6 to 18 inches) apart, depending upon the stock variety.

Caring for Stock - Matthiola plants

Matthiola Care: Once established in the garden, pinch the young stock (Matthiola) plant shoots back to encourage taller growth.

It is best to have the plants located close together to increase the amount of blooming.

Matthiola plants are easy to look after, water regularly and feed once a month.

If you require more plants then the perennials can be propagated by taking cuttings in the summer.
