The seedlings will require watering, several fertilizing, and hardening off before planting in the ground. To form a beautiful bush, pinch the top.
When the cold weather goes away, the seedlings can be sent to the flowerbed.
Zinnia is planted in a flowerbed at a distance of 30-35 cm from each other, the same distance is given between the rows.
Alternatively, you can grow zinnias at home by starting to plant them about 4-6 weeks before the end of frost.
How to replant zinnias.
If you want to transplant zinnias from trays, note that the soil temperature should be between 21-26°C (70-80°F).
Zinnia graceful needs regular watering throughout the growing season.
Starting in spring, you should plan to water this plant about once a week. As the warm season approaches, watering can increase to two to three times a week.
Trimming. Pinch the tip above the 3rd or 4th pair of true leaves for a fuller, more compact plant.
Pinching is the removal of the apical growing point, which provokes the appearance of lateral shoots and, as a consequence, tillering.
