FAQ
What’s the best time to sow wildflower seeds?
Generally, wildflowers are best sown in autumn (September-November) for a natural spring display or early spring (March-April) for an earlier bloom. Soil temperature is key – aim for at least 7°C.
Do I need special soil for flower garden seeds?
While most seed mixes can be sown in general purpose compost, a seed starting mix provides excellent drainage and aeration crucial for germination. Incorporating some horticultural grit into the mix improves root development.
How much sunlight do most of these plants require?
Our collection includes varieties suited to full sun (6+ hours), partial shade (4-6 hours), and even shady conditions (less than 4 hours). Always check the individual plant descriptions for specific light requirements.
What’s the difference between annuals and perennials?
Annual plants complete their life cycle in one year, requiring replanting each spring. Perennials live for more than two years, returning reliably year after year – providing continuous colour.
How do I care for pansies in my flower garden?
Pansies thrive with regular watering and feeding, particularly during flowering. Deadheading (removing spent flowers) encourages further blooms and maintains a tidy appearance.
Can I grow lavender in a pot or directly into the ground?
Lavender does well in both! In pots, use a well-drained soil mix like gravel and compost to prevent root rot. Direct sowing requires full sun and excellent drainage.
What’s the best way to protect seedlings from frost?
Cover newly sown seeds or delicate seedlings with horticultural fleece until the risk of frost has passed. Alternatively, move potted plants indoors during cold snaps.
How often should I water my flower garden plants?
Water deeply and less frequently – allowing the soil to dry slightly between watering. Frequency depends on weather conditions; hotter, drier periods require more frequent watering.
What’s a good fertiliser for flowering plants?
A balanced liquid fertiliser applied every 2-4 weeks during the growing season will provide essential nutrients. Look for one with a higher potassium content to promote flower development.
Are there any specific requirements for sowing cosmos seeds?
Cosmos seeds benefit from being sown directly into well-drained soil after the last frost. They germinate quickly and require full sun for optimal growth and prolific flowering.
