Are geraniums easy to grow from seed?
Geraniums are relatively easy to grow from seeds. However, they are slow growers which should be sown in early to mid-February to produce the flowering plants you want for spring. Flowering occurs approximately 13 to 15 weeks after sowing.
Here at Thuss Greenhouses, seed geraniums are one of the very first seeds sown to start the season. Most years their seeding occurs the last week of January or the 1st week of February so they are ready for early May.
Seed geraniums are different from Zonal Geraniums in that zonal geraniums are propagated by cuttings while seed geraniums are grown through seeds. Seed geraniums are a compact version of the zonal geranium, growing less than one foot with smaller, more numerous flowers, while zonal geraniums are taller with larger flower heads, but not as abundant.
Seed geraniums can be a great landscape flowering plant, outperforming zonal geraniums all summer long. They pack a solid punch of colour, with amazing bright hues coming in a wide array of colours from neon pinks and the softest of baby pinks, to reds, oranges, purples and whites.
You should deadhead whenever your geranium blooms begin to look brown or weak. To deadhead your geraniums, rather than simply pulling off the top flowers, you need to go a little deeper in the plant and snap the stem below its node or joint, where new growth begins. This also gives the plant a more cosmetic look without empty stems standing alone.
Feeding your geraniums throughout the season will help keep them looking great all summer long! Miracle-Gro All-Purpose plant food is full of all the essential nutrients that plants need to survive and thrive. Feed the geraniums once every 1 to 2 weeks. This water-soluble mix is instant release so the plant receives the nutrients immediately.
One of the most common reasons for geraniums not blooming prolifically is too little light. Geraniums are a sun loving plant that need 4-6 hours of full sun a day. Don’t forget to water them!
