No sunny summer flower garden is complete without the sure colour of tall garden zinnias. These bright and unique blooms are quite a conversation starter! The blooms measure 5 cm (2 in) across and have a super-packed, semi-double form that holds up well in garden or vase. Ht 75 cm (30 in).
Sow seed outdoors as soon as soil can be worked. Cover seed very lightly and keep the soil moist until all seedlings appear. For earlier blooms start seed 4 weeks prior to intended date of transplanting outside. Germinates best at 21 C (70 F) in 7-10 days. Reduce heat after 3 – 4 leaf stage to 15 C (60 F). Transplant as soon as possible to prevent shock. Fertilize every 2 weeks with 10-52-17 and liquid seaweed for strong healthy plants. Garden spacing 30 cm (12 in) apart.
