Indoor And Outdoor Seed Options For Zinnias
When it comes to planting zinnias, there are two options to consider:
-
Starting them indoors: Sow zinnia seeds from February to April, allowing sufficient time for plant development before transplanting them outside. This method offers a head start and can lead to earlier blooms. To begin, sow the seeds in trays or modules filled with free-draining compost. Keep the soil moist but not soggy, and place the trays in a warm, well-lit location.
-
Directly sowing into the soil: If you prefer to sow zinnias directly into the soil, wait until May when the danger of frost has passed. Prepare the planting area by ensuring the soil is well-drained and fertile. Remove weeds and debris before sowing the zinnia seeds at a depth of approximately ½ inch. Initially, space the seeds a few inches apart. Once the plants have four leaves, thin them to a spacing of 8 to 18 inches apart.
Important Tips:
- For indoor planting, sow zinnia seeds from February to April.
- For direct sowing, wait until May.
- Ensure the soil is well-drained and fertile.
- Keep the soil moist but not soggy when starting zinnias indoors.
- Thin the plants to a spacing of 8 to 18 inches apart once they have four leaves.
Remember: Zinnias are beautiful flowers that can be grown either by starting them indoors or sowing them directly into the soil. Choose the method that suits your preferences and enjoy the vibrant blooms!
Tips For Growing Zinnias From Seed
To successfully grow zinnias from seed, here are a few key tips to keep in mind:
-
Use fresh seed: It is recommended to grow zinnias from fresh seed each year to achieve the desired color mix. The germination rate of saved seeds may decrease over time. Purchase fresh seeds or collect them from zinnias grown in your own garden.
-
Care for disease resistance: Zinnias are relatively easy to care for, but they can be susceptible to diseases like powdery mildews, mold, and leaf spots. Take preventative measures by regularly picking flowers and removing affected leaves. Proper air circulation is crucial, so avoid overcrowding the plants. Provide adequate spacing and orient the zinnias to receive sufficient sunlight and airflow for their overall health.
-
Feed regularly: Zinnias benefit from regular feeding with a liquid fertilizer to ensure optimal growth. Follow the package instructions for dilution and frequency when applying the fertilizer. Overfertilization can result in excessive foliage growth at the expense of flower production.
