Matthiola are upright-growing, fragrant, annual flowering plants. They are more commonly known as flowering stock. Matthiola are indigenous plants to regions in Southern Europe. They can be grown as bedding plants, along borders or in containers. Matthiola will bloom through early through mid-summer and are easy to grow from seed, if given cool growing conditions, full sun and lots of loamy soil.
Planting Matthiola Seeds Outdoors
Weed and cultivate the planting area you’ve chosen for growing the matthiola seeds. There should be no weeds, rocks, sticks or any objects left in the planting are which could cause problems with the germination of the matthiola seeds. Mix into the soil a 2- to 3-inch layer of rotted manure, compost, leaf mold or any similar natural media.
Smooth out and level the planting area using a metal garden rake. Scatter the matthiola seeds over the planting area. Try and plant them so the matthiola seeds are about 2 to 3 inches apart from each other.
Push the matthiola seeds firmly into the soil using a garden hoe, a trowel, or the base of your hand. Sprinkle garden soil over the matthiola seeds to cover them up with about ¼ inch of soil. Water the area lightly, using a fine mist of water.
Push in 12- to 14-inch-tall planting stakes around the perimeter of your planting area. This is useful so you can know where you need to water.
Mist the area with water as often as needed to keep the seed-bed moist, but never allow the soil to become so wet it gets to be soggy. In about 7 to 10 days, you will see matthiola seedlings emerging from the planting bed.
Planting Matthiola Seeds Indoors
Scoop seed-raising compost into planting packs. Firm the soil down in each of the packs using the base of a smaller sized growing container, or a metal spoon.
Pour about 1 inch of water into a shallow irrigation tray, or watering tray. Transfer the planting packs into the tray. They should be allowed to soak up the water to saturate the growing media.
Plant two to three matthiola seeds into each of the cells in the planting packs. Gently push the matthiola seeds down into the growing media using the tips of your fingers. Scatter approximately 1/4 inch of the seed-raising compost over the matthiola seeds.
Put the irrigation tray, or watering tray where it will receive ample light, and warmth. Don't put the tray where it's going to get direct sunlight, but try and put it where it will receive filtered bright light for about 8 to 10 hours each day. The temperature should remain between 55 and 65 degrees F. In about 7 to 10 days you will see the matthiola seeds sprouting. Keep the growing media moist; add water to the irrigation tray, or watering tray as required.
Transplant the matthiola seedlings into their permanent location outside after no further frost is expected in your growing region.
