Caring for your Geroldii:
Geroldii can be quite beautiful when they are well-taken care of.
When planting this succulent in a garden, make sure it gets sunlight. Partial sun is the best for its growth. It can be grown with plenty of success outdoor or indoor.
Geroldii prefers a warm climate. If you live in a cold area, it is better to grow it in an indoor environment. As long as it gets enough sunlight, the plant will grow happily.
Allow your plant’s soil to dry out completely, and then water thoroughly. I take my plant to the sink, soak the soil thoroughly, allow the excess water to drain completely, and back to the window it goes. Euphorbia Geroldii grows best in a gritty, well-draining mix which allows it’s roots to dry in-between watering.
If you notice your plant is wilted and your soil is bone dry, immediately take it to your sink. Soil that has gone dry for a long time is sometimes very hard to “re-wet.” When you water your plant, you’ll notice that most of the water will run right through.
Repeatedly water a few times in a row until the soil is moistened again, and try not to allow it to get to that point again. If you haven’t waited too long, your plant will bounce back!
On the contrary… don’t even think about watering again until your soil has dried out pretty well. Never let your Euphorbia sit in water, whether there is water in its saucer or inside its cache pot, or it will rot.
And always make sure your pot has a drainage hole!
Being a Euphorbia, this plant has a toxic sap that should be completely avoided. Gloves and safely eyewear should be used when handling this plant.
Euphorbias typically produce a white, milky sap, called latex, that is relatively irritating to us humans. It is, however, quite useful to the plants themselves. One of the reasons these plants are so easy to grow is these saps have some degree of antifungal and antibacterial activity, which probably keeps them from getting infected easily in cases of injury. And the saps act as excellent wound sealants.
Cuttings of these plants often self seal with this latex which I find useful- saves on antifungal powders, and these plants can often be rerooted right away thanks to their latex healing the cut site almost immediately. And of course the latex presumably repels would-be predators that are looking for a plant meal, from insects to large vegetarian mammals.
