These clamshells are packed full of succulent plants. They can be used for table decorations or make great house presents. You can use a mix of succulent plants, or use one type. These are planted with a few different kinds of hens and chicks, and some tiny echeverias.
As when planting any succulent, use either a potting soil made specifically for succulents and cacti, or make your own by taking a good quality potting mix and adding either pumice or perlite. Make sure to use a container that either has drainage holes one that you can punch or drill holes in. Drainage is key to keeping your succulents healthy.
To care for these miniature container gardens, give them full sun, or if you are in a very hot climate, keep them in partial shade. Do not over water. During the growing season, keep the soil moist, but not wet. During the winter, when succulents go into dormancy, let the soil dry out between waterings.
Hens and chicks are incredibly forgiving plants. They are extremely hardy - most of them can survive in zone 3, and can tolerate poor soil. For Step by step instructions on making clam shell container gardens.
