Plant my common blue wood aster

Choose a place in semi shade - to ensure a beautiful flowering! - and cool for these asters. Prepare the soil by digging (to decompact without necessarily turning it, with a fork or a grelinette), scratching and raking. Plant at a spacing of 1/3 of adult height between plants. Thoroughly tamp the soil so as not to let air in contact with the roots, then water abundantly.

Water my common blue wood aster

Asters do not particularly fear drought. Water grownup plants until the water that you pour does not rush into the ground, and forms a small puddleto their fill, even if it is less frequent. Unless otherwise specified, do not wet the foliage: the plants "drink" by their roots. Seedlings should be watered in fine rain. Keep them permanently moist to get germination.

Weed my common blue wood aster

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

Cut down my common blue wood aster

Cut the asters a few inches off the ground in November, before mulching them.

Fertilize my common blue wood aster

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 common blue wood aster

Harvest the seeds if you'd like to propagate your plants! Multiply them by seeding in a pot under a cold frame in autumn or spring, after removing the caustic external flesh of the berries, then transplanting them in open soil after the last freeze.

Prop my common blue wood aster

Train any asters taller than 80 cm in March, otherwise they may droop and sag after rain. A stake and a wire should do the job.

Mulch my common blue wood aster

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.
