The aubrietes support a dry and well drained soil, and appreciate the limestone.
Dip the clumps in a tray filled with water to have them well moisten. Plant them when the water is no longer flowing out of the bucket.
Prepare the soil: make holes with a spacing of 20 to 30 cm, and mix the soil with fibrous compost and sand. Put a plant in each hole. Cover with soil by tamping gently to avoid air around the roots, then water.
In pots and planters, place a layer of gravel at the bottom, then plant your aubriete in a mixture of sand and compost or fibrous compost.
Water my aubrieta
In the first month after planting, water twice a week.
Water during the summer if it is very dry, once a week, rather in the morning taking care of sparing the leaves.
In pots and planter, water as soon as it has not rained for a week, until the dish is filled.
Fertilize my aubrieta
In early winter or early spring, apply some organic matter or compost at the bottom of your aubrieta.
No need to incorporate it deep, it will work for some time as mulching, and then soil micro-organisms will break it down. It will provide a regular supply of nutrients to your aubrieta; better than a slow fertilizer!
Propagate my aubrieta
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.
Check on my aubrieta
The main enemy of the Aubrieta is white rust. It enjoys high atmospheric humidity, or watering too frequent.
Do not crowd the plants, and avoid watering the leaves.
Damage due to nematodes, aphids and flea beetles may also occur, but should not require treatment.
