Plant my coreopsis
Plant the coreopsis bought in a bucket from March to May or from September to October, in open soil or in pots.
Choose a rich, but well-drained, soil in semi-shade or full sun. Coreopsis is drought resistant.
In pots, prefer a sunny spot, and a substrate composed of potting soil and garden soil. In the open soil, dig a hole 3 times the size of the root ball. Mix several compost handles with the original soil - if your soil is heavy add coarse sand or gravel for better drainage. Soak the root ball for 3 minutes.
Install the plant and refill the hole. For a more beautiful effect, install at least 3 plants spaced 30 to 40 cm apart. Place very large varieties preferably at the bottom of the flowerbed.
In pots, drain with clay balls or gravel and add the mixture of potting soil and garden soil.
Sow my coreopsis
You can sow directly in open soil, in-line or spreaded on an area, ideally between March and June, in well-drained, well-prepared soil.
Thin out my coreopsis
Three or four weeks after sowing in open soil, thin to one plant every 15 to 20 cm when the plants have 3 or 4 leaves.
Weed my coreopsis
The first month, to give your seedlings enough time to grow, weed a little around them.
Mulch my coreopsis
Avoid watering and weeding; mulch the foot of your coreopsis after planting.
Water my coreopsis
Water in the first weeks, and in case of very hot weather.
Keep the seedling substrate a bit moist.
After planting, let the soil dry between two waterings until growth begins, and then water again.
Once properly grown, you will only need to water your plants in dry and windy weather or in case of prolonged drought.
Propagate my coreopsis
Coreopsis multiplies easily by slicing the tuft in March. Cut it in the middle with a spade, dig a new hole, and voila ... A few handfuls of compost and a small watering can later, you have a new coreopsis.
