Lavatera trimestris 'Mont Blanc' - SeedsMallow, Annual Lavatera

Fill a seed tray with good, free-draining, damp, seed compost. Sow seed on the surface of the compost and cover with a very fine sprinkling of dry vermiculite or finely sieved compost. Place the seed and tray in a propagator or seal inside a polythene bag and keep at around 18-23C (65-75F) until the seeds germinate. This will take about 14-21 days. Don’t exclude light as this helps germination.

When the seedlings are large enough to handle, transplant them individually into 7.5cm (3") pots or multi-cell trays and grow them on in cooler conditions. Before planting out, acclimatise the plants to outdoor conditions by putting them outside for a few hours a day for a few weeks. Plant out after all risk of frost has passed at a distance of 45cm (18") apart. Plant in any light, sandy soil in full sun.
