Rumex - sorrel - is a genus of dicotyledonous herbaceous plants of the family Polygonaceae. Its leaves are up to 15 cm long and rounded, light green in color: they resemble those of spinach. The very recognizable fruit is an achene with three membranous wings; the fruits are grouped in clusters.
Sow my dock
The sorrel appreciates heavy soils and clay soils, neutral to acids, very humiferous, and hardly tolerates the calcareous soils.
It can easily be grown in pot on the edge of a window at home, but also in open soil, in ornemental or in vegetable garden. Find him a semi-shade spot.
Sow in nursery from March to June, or in the garden after the last frosts. Cover the seeds with about 1 cm of potting soil.
Water the seedlings frequently to keep the soil moist.
Dibble my dock
For sowing done in open ground, transplant the plants every 20 cm when 3 or 4 leaves appear.
Repot the seedlings under shelter in individual buckets, again at the appearance of 3 or 4 leaves. You will set up in the ground once all risk of frost are away.
Associate my dock
In the vegetable garden, place it in the company of asparagus, watercress, carrots, spinach, strawberries, beans, peas, radishes, lettuces, tomatoes but also rhubarb.
Plant my dock
For plants purchased in pots, plant sorrel in the spring or fall, knowing that in regions with mild climate, planting can be done all year round except during frost.
Water my dock
Water the seedlings regularly, and watch for hot weather. Know, if you want to harvest, that sorrel is more bitter if it is grown in moist soil!
In pot, water once or twice a week in warm weather, once every 2 weeks the rest of the year.
Mulch my dock
Mulch the base during the weeks following the final planting, to keep the substrate moist.
In areas with a cold climate and even if the plant is hardy, plan a mulching for the winter.
Repot my dock
Repot annually, ideally at the end of autumn for sorrel grown in pots, changing a good part of the substrate.
Propagate my dock
Divide the tufts in the spring, every 3 or 4 years.
Clean the clod, and equip yourself with a clean, sharpened and even sanitized spade: slice dry, and transplant.
Reap my dock
Harvest as and when needed by focusing on the leaves that are most developed. You can harvest about 3 months after sowing, but know that the harvest will always be more productive from the second year of cultivation.
Consume fresh - it's better! - or freeze eventually.
Check on my dock
The sorrel is robust but is prone to attack by slugs, aphids and sorrel maggot. Slugs love to devour young leaves, leaving a bright trail as they pass over the plant. The usual methods work partially: ashes, eggshells - but slugs love sorrel!
Aphids suck the sap of plant leaves which become sticky, curl and deform. Eliminate the aphids by hand or with a jet of water, or spray the plant with water mixed with black soap. Favor also in the garden the presence of their direct predators: ladybugs! By providing them a living space, letting the grass grow higher for example.
The sorrel fly deposits larvae on the leaves. These dig galleries that kill the leaves. Burn the affected leaves, and do not compost them.
