Alyssum Seeds 'Carpet of Snow' - Unwins

You can sow 'Carpet of Snow' seeds directly outdoors in spring after the last frost, or in early autumn for overwintering in milder climates. For an earlier start, sow indoors 4-6 weeks before the last expected frost.

This can be due to insufficient sunlight. Move plants to a sunnier location if possible, or ensure they are receiving at least 4-6 hours of direct sun daily.

Plants may not be getting enough light or nutrients. Prune back leggy stems to encourage bushier growth and consider a light feed with a balanced liquid fertilizer.

Common issues include aphids. Inspect plants regularly and treat with insecticidal soap or neem oil if necessary. Ensure good air circulation to prevent fungal issues.
