🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.

😖 Common Issues

Overwatering is a likely cause of issues with Twin Spined Cactus. These plants are very sensitive to wet soil so if you notice your plant becoming squishy or translucent, overwatering is the likely culprit.

Cut your plant just past where the rot ends and allow it to callus over for a few days before replanting it in fresh, dry soil. Download Greg to make sure your plant never gets overwatered again!

This was my husband’s plant and I was to be “hands off”. Well, he didn’t do much for the thing and it got REALLY sad. It trooped on for A LOOOONG time, and sent out a few pups in an effort to save itself. I took over, potted these pups, and am committed to doing right by this plant. I can tell you, their momma persevered for years on zero love and support. This species is a true survivor.

So far she is doing well, I got her at a very good price. 50% off when Krogers was having a sale, plus I got an extra 15% off so I paid less than $2.00 for her.
