Growing instructions for the Desert Globemallow
The seeds have a hard seed coat that has to be treated, or scarified, in order for water to enter the seeds so that they can sprout. 1. Scarify the seeds by nicking or sanding the seed coat. The seeds can be sanded with sandpaper, a nail file or an emery board. 2. Soak the seeds in water for several hours. 3. Put the seeds in a ziplock bag. 4. Put the bag in the refrigerator and leave it there for 30 days. 5. The seeds like moist, well-drained soil. Prepare a mixture of half potting soil and half sand, perlite or vermiculite. 6. Put the soil in a pot. 7. Sow the seeds on the soil. Cover them with a layer of soil. 8. Water the soil so that it is moist but not wet. 9. When the seedlings are a few inches tall, they can be transplanted.
