🌱 How to Care for Summer Snapdragon to Prevent Aphids?

💧 How to Water

Water deeply when the top 2-3 cm (about 1 inch) of soil feels dry, then let it drain completely. In containers during hot weather check moisture every 1-2 days; in garden beds, established plants tolerate short dry spells. Never let the plant sit in waterlogged soil.

☀️ Lighting

Provide at least 6-8 hours of direct sun daily. Indoors, place within 30 cm (1 foot) of a bright, sunny window; outdoors, full sun produces the densest flower spikes.

🪴 Ideal Soil

Use a rich, well-draining soil with a slightly acidic pH between 5.5 and 6.2. Amend heavy or clay soil with compost, and ensure containers have drainage holes to prevent standing water.
