Zinnias are from Mexico and prefer hot and dry climates. They cannot withstand low temperatures and frosts. Too much humidity, and they will develop diseases.
Plant Zinnias in direct sunlight. The more sun you provide to them, the more healthy they will be and more flowers will grow.
The ideal is to keep the soil slightly moist during the initial growth, allowing the soil to dry superficially between waterings when the plants are well developed.
Zinnia is a relatively drought-resistant plant. On the other hand, it does not grow well in excessively moist soil.
As long as the soil is well drained and light, Zinnias will grow happy. Ideally, it should be fertile, rich in organic matter, with a pH between 5.5 and 7.5.
In climates with cold winter, it blooms in summer and early autumn.
In hot climates, with suitable conditions, it can bloom all year round. It usually begins to bloom approximately 45 to 70 days after germination.
