How To Grow Petunias From Seed
Growing Petunias from Seed – Petunia seeds are quite small, however elite strain seeds are sometimes provided in pellet form, making them simpler to handle. Petunia seeds, whether pelleted or uncoated, are sown by pressing them gently into damp seed-starting mix.

Then, sprinkle additional mixture until the seeds are just barely coated.
The seeds typically germinate in seven days if kept warm and wet.
Consider petunia seedlings to be little tomatoes or any other Solanaceae relative.
Transfer them to larger containers as necessary, and be patient with the process of hardening.

How long do petunias take to develop from seeds?

Starting seeds inside – Although petunias are simple to cultivate outside from transplanting, inexperienced gardeners may find it more difficult to grow them from seed. The benefits of beginning petunias inside include a greater selection of cultivars and the ability to cultivate huge quantities of plants for less money.

However, it takes petunias 10 to 12 weeks to reach planting size, so they must be started early (about March first in northern climates).
This implies there is considerable possibility for issues to arise between sowing and harvesting! Even for expert gardeners, petunia seeds provide a problem due to their size.

Not only are they exceedingly little and delicate, but they also require light to germinate. Pelleted seeds are more manageable, but they are not always accessible. On top of a container of clean, moist potting soil or ground sphagnum moss, scatter seeds sparsely.

Before watering, wash them into the potting medium with a thin mist or press them in with your fingertips. Until the seeds sprout, cover the container with transparent plastic and store it in a bright, warm (70 to 85 degrees F) location away from direct sunlight. This often occurs seven to ten days after planting.

Remove the plastic after the seeds have emerged. Move the container to a light but cooler location, with daytime temperatures of 65 degrees Fahrenheit and nighttime temperatures of 55 to 65 degrees Fahrenheit. Place the petunias four to six inches underneath a fluorescent light lamp until they are ready for outdoor planting.

You are not need to invest in pricey plant-growing lights. Typically, standard fluorescent bulbs will suffice. Utilize a timer to keep the lights on for 16 to 18 hours every day. Raise the lights as the seedlings develop, maintaining a 4- to 6-inch distance between the plants and the lights at all times.

When seedlings have three genuine leaves, it is appropriate to transfer them to individual peat pots or multi-plant packs. Every two weeks (every week for “spreaders”), provide them with diluted liquid fertilizer. Young plants can be hardened off by placing them outside on bright, warm days.
