How to propagate Sweet Pea 'Matucana'


Sweet peas are best sown in autumn or spring. To help them germinate, soak the seeds overnight to soften their outer coats. Direct sow outdoors in April and May. It is vital to prepare your soil well. Turn the soil over to a depth of 30cm and add plenty of compost. In the well-prepared soil make holes 2-3cm deep and about 10-15cm apart. Drop seeds in and press down firmly on soil. Keep moist until they start sprouting. Alternatively you can start indoors, either in Sept and Oct. or from Jan to March. Sow 5 seeds into 5cm pots, lightly cover with compost. Water after sowing, but not again until after the seedlings have emerged. Maintain the pots between 10 and 15°C (50-60°F). Plant out after the risk of frost has passed.
