Identify my creeping woodsorrel
Option 1: Look at the merchant's label;
Option 2: The oxalides carry 3 or 4 more or less heart-shaped leaflets, and white, yellow, mauve or red five-petalled flowers.
Plant my creeping woodsorrel
Oxalides are found in tubers or scoops.
Plant preferably in spring, in the open-soil if your climate is mild, otherwise in pot for the species that you will have to shelter: Oxalis triangularis, Oxalis brasiliense and Oxalis tuberosa.
Oxalides like a light soil, fresh and humus.
Bury the tubers 5 to 10 cm, and space them about twenty centimeters.
In pots, mix soil, decomposed compost and sand in a pot of 3 liters.
Weed my creeping woodsorrel
For perennial species, weeding also means working your flowerbed – don't let anything develop too quickly to the detriment of others.
Water my creeping woodsorrel
Water during the summer season, once a week in case of dry weather, in the morning if possible. Water also during first month after planting, twice a week.
Propagate my creeping woodsorrel
This should not be necessary: the oxalides multiply quite efficiently without outside help!
Mulch my creeping woodsorrel
Each year, renew the mulch layer around your oxalis in the spring. It will help flowering by enriching the soil.
Fertilize my creeping woodsorrel
A small glass of compost juice diluted to 10% - with 90% water - every week in the summer, presto!
Protect my creeping woodsorrel
Oxalis triangularis, Oxalis brasiliense and Oxalis tuberosa need to be sheltered in winter, protected from light, dry and cool.
You have trouble recognizing them?
- Oxalis triangularis has purple leaves with triangular leaflets.
- Oxalis brasiliense has pink, red and then purple flowers.
- Oxalis tuberosa is grown in the kitchen garden to eat its tubers, and it is one meter wide. If you do not want to shelter them, eat them ;-)
