Pansy Inspire Plus White

Pansies are not difficult to raise from seed. For autumn planting to flower in spring, seed can be sown at any time from May to early July. A soil-less compost is suitable but should have extra perlite added if you suspect the drainage may be poor. Cover thinly with vermiculite and place in a temperature of 59-65F to germinate. High temperatures and fluctuating moisture levels are the most likely causes of failure.

Prick out the viola seedlings when they are large enough to handle using a similar compost. They can either go into trays or use 7cm square pots. The plants can grow on in a frame until the September when they will be ready for planting. For containers and for hanging baskets in particular, planting in early spring is often more successful. In this case a later sowing is suitable, August or September, and the seedlings should be pricked out into 9cm pots and grown through the winter in a cold frame before planting up in early March. They should only be covered in severe weather.

If you should wish to grow them for summer flowering, sow the seed in March and raise them like summer bedding.

Pansies suffer from few problems. Aphids are the most common and a regular spray with a suitable insecticide will see them off. Slugs can cause problems in wet seasons but perhaps the thing that causes the most disquiet is leaf spot.
