Identify my knotted crane's-bill

Geraniums are small, hardy perennials with more or less persistant foliage. The leaves are rounded and split either into palms or five points. The flowers may be flat or star-shaped, and come in shades of pink, purple, blue and white.

Plant my knotted crane's-bill

You may plant perennial geraniums in autumn or spring. Leave a space of about 80 cm around and between each plant Prepare the soil with some light digging (to decompact without necessarily turning it over with a pitchfork or broadfork), hoeing, and raking. When planting, leave approximately 20-20 cm between plants. Tamp the soil down well so that the roots are not in contact with air, then water generously.

Water my knotted crane's-bill

Water when the plants are in bloom, keeping a particularly close eye on potted plants. Always thoroughly water adult plants even if that means doing it less often; the plant will develop a better root system if it must look for water deep underground. "Thoroughly" means that the water you pour is no longer absorbed by the soil and forms a little puddle. Unless otherwise stated, never wet the foliage: plants "drink" with their roots. The seedlings need to be watered with a light shower so as to not turn over everything. Keep them constantly moist to encourage germination.

Weed my knotted crane's-bill

In perennial species, weeding also means working your flowerbed – don't let anything develop too quickly to the detriment of others.

Cut down my knotted crane's-bill

Deciduous perennials don't keep their above-ground growth during the winter, they survive with their underground systems. At the end of the season, the foliage and the dried flower stems can be cut off without second thought. Don't touch the root or the future buds that are emerging from the soil

Fertilize my knotted crane's-bill

With a respectful approach to soil life, it's always better to fertilize a little in advance with organic material that will decompose; spread out a compost that isn't entirely decomposed, with well decomposed manure at the plant's base, and incorporate over 10 cm with a hoe. This operation is carried out in winter so that earthworms and bacteria have enough time to do their job.

Propagate my knotted crane's-bill

It's easiest to multiply your geraniums by dividing the tufts in spring, which will also allow them to air out a little. You can also multiply your geraniums by sowing outside in an earthenware pot, either in spring or at the height of seed maturity.

Mulch my knotted crane's-bill

Mulching these perennials will save you from watering and weeding and will even fertilize the soil a bit as it decomposes. When choosing, know that dry wood chips are the most inert, but they will last for a longer time. Fresh wood chips and leaves enrich the soil but must be changed often. Grass cuttings are to be used mixed with something else in a layer that is at most 1 cm thick. Mulch with a thickness of at least 5 cm to provide a good level of efficiency.
