Oxalis Iron Cross Water Requirements The Oxalis Iron Cross has a relatively moderate water requirement, as this plant is native to Mexico it can be somewhat drought tolerant as well, especially if it is growing in partial shade.
Watering: Keep soil evenly moist, watering when the surface of the soil feels dry.
They had several so I picked up two more pots of those, too.
Keep the soil slightly moist and ventilate the cover daily to prevent mold.
Some varieties are tougher to grower error than others.
We recommend cleaning out the flowers promptly, so that the lucky clover does not invest unnecessarily its valuable plant energy into the growth of the seeds.
