These plants shouldn't be grown in the garden during the cold period; in autumn the plants usually perish, and should be eradicated from the ground. The Zinnia can't stand cold weather, therefore in general it should be grown in a sheltered place; during the Spring months, when the minimum temperatures are above zero, it can be moved outside.The Zinnia should be preferably located in a place where it can have at least a few hours a day of direct solar light.
Water Zinnia
As the cold weather arrives, in autumn, we can interrupt watering, and let the plants perish. Let's water abundantly, moistening the soil deeply with 2-3 glasses of water , but let's act only when the substratum is dry, leaving it dry even for 1-2 weeks before watering it.
Fertilize Zinnia
Before placing the annuals, let’s enrich the soil with a small dose of organic fertilizer or slow release granular chemical fertilizer; during the spring we should use a specific fertilizer for flowering plants to be mixed with the irrigating water, to be used every 20-30 days.

Pests Zinnia
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there aren’t flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.
