Geranium Seeds ‘Horizon White’
- Clusters of pure white flowers
- Drought-tolerant
- Flowers all through summer
- Perfect for containers
Geranium ‘Horizon White’ looks fresh and cool all summer long, with masses of big, pure white flowers that stand out against the foliage. It makes a superb addition to containers and window boxes, and regular deadheading will keep the flowers coming into early autumn.
Sow indoors
Almost fill a small seed tray with moist seed compost. Sow seeds thinly and lightly cover them with a little more compost. Place in the warmth, 20-25°C, and keep moist. Lower temperatures inhibit germination.
Grow on
Keep seedlings in a light position, but shade from direct sunlight. When large enough to handle, transplant individually to 8cm pots. As young plants develop, grow on at between 10-15ºC.
Plant out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out when the danger of frost has passed. Allow 30cm between plants.
Aftercare
Geraniums benefit from regular feeding through the flowering season and the removal of dead heads.
