This morning, at Bethlehem Lutheran I attached some potato and onion sacks to the fence to serve as a barrier to keep the soil inside the garden. In order to make it prettier, I also planted some succulents along the fence. Their roots will not only hold the soil in place, but it also grow strong with out much water.
Succulents (plants with a waxy coating on their leaves - like aloe) are a great addition to California gardens, because they can cover large spaces and conserve valuable water resources. Mixing lots of different types of succulents next to each other can also make a very beautiful look and provide rich textures. I also think that the green and purple of the succulents look really beautiful next to the orange of the potato sacks.
Succulents are very forgiving, so they're great for inexperienced gardeners. You can transplant them by breaking off a branch/stem and simply sticking it in some soil. Just be careful not to over water them. You'll know if this is happening because they will start to turn brown.
