Identify my eastern bluestar
Amsonia tabernaemontana commonly referred to as the eastern bluestar is a perennial species of the family Apocynaceae.
It is a tuft with many stems. The leaves are small, elliptical, dark green. Flowering occurs from May to July in 2cm panicles of rounded cymes.
Plant my eastern bluestar
Amsonies support ordinary, cool, well-drained soil. Find a location in the sun.
Dip the clumps in a tray filled with water to moisten them well. Plant them when the water is no longer flowing out of the bucket.
Prepare the soil: make holes, leaving a spacing of 20 to 30 cm between each, and mix the soil with potting soil and sand if it is heavy.
Put the plants in there.
Finish filling with soil and tamp it gently to avoid air around the roots. Water a lot.
Weed my eastern bluestar
In perennial species, weeding also means working your flowerbed – don't let anything develop too quickly to the detriment of others.
Water my eastern bluestar
Water during the summer season once a week if the weather is dry. Remember to keep the leaves dry !
Fertilize my eastern bluestar
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 eastern bluestar
You may divide the plant in autumn.
Chose an older part of the plant that no longer flower well.
Dig it up with the help of a pitchfork, taking care not to destroy the roots. Drive the pitchfork into the centre of the clump to divide it in half, in one good cut. Replant the two parts of the plant immediately.
Mulch my eastern bluestar
Mulch, it will prevent you from watering and weeding in summer, and - even if they are rather hardy: it will protect the roots of cold in winter.
Cut down my eastern bluestar
After flowering, cut back your plant to a compact shape.
