When you have a die-cast vehicle to showcase, you can create your landscape around a driveway.
Succulents are easy to work with and care for – you can ignore them more than any other plant. Give them plenty of sun. Water when completely dry (and you can even let it stay dry for quite a bit). They can handle heat well. If there is frost or freezing temperatures, keep the garden inside in a well lit window. When you want to create more succulents, most will propagate by simply breaking off a piece and sticking it in the ground – with no root stimulator necessary. This is also great when a piece of a cactus breaks off accidentally (awww!) and you get a whole new plant from it (yay!).
Cactus replanting tip: use heavy duty gardening gloves or use a piece of rolled newspaper folded around the plant to lift it and place it in its new home.
