Cranesbill geranium care is really very easy, but they do need appropriate care for selecting the best site and soil that they will make them thrive and flower the best.
You should know that cranesbill is the common name of the Geranium genus and should not be confused with Pelargoniums.
So now I will give you tips for how to care for geraniums, and where to plant them, and care for them the best way.
Geraniums are so easy to grow, are very versatile, and long-flowering, and few plants are so useful in a garden as these hardy geraniums.
Site and Soil
For Hardy Geraniums
Most geraniums like well-prepared, fertile, moisture-retentive soil.
They grow best in sun, but are quite undemanding and some, G.macrorrhizum, G.endressi, G. x cantabrigense, and G.phaeum are especiially drought and shade tolerant.
I recommend planting sprawling varieties, such as G. Ann Folkard and G. Rozanne among perennials that are tall, and near, or around rose bushes, so they can ramble around at will.
Geranium Plant Care
You can apply an all purpose fertilizer in late fall, or in spring (or both)
Tall growing varieties such as G. maculatum, G. pratense, and G. psilostemon should be supported with sticks if you are growing them as border plants.
Many cranesbill plants benefit from a mid-season cutback, but not all of them will repeat-flower after such a pruning.
You’ll have to learn this by trial and error, as you experiment with mid-season trimming.
If you cut back, carefully, after flowering, G. phaeum var. phaeum ‘Samobor’, will repeat-bloom and grow fresh new leaves that will look great until frost comes.
Deadheading is really not necessary and won’t accomplish much. Although, in some cases, trimming back (see above) will encourage more flowers.
Winter Geranium Care
Cranesbill geranium varieties are hardy, and they die back to the ground in winter.
They will emerge every spring with fresh new foilage, ready to bloom for a new season.
You can increase cranesbill geraniums by dividing them in early spring, or late fall.
G. ‘Ann Folkard’ can also be propagated by basal cuttings, because this plant has a loose crown. This you do by taking a small piece from the crown of the plant, to which a few roots are attached.
Some varieties such as G. pratense, G. pyrenaicum, and G. palmatum will self-seed.
