Succulents are plants that store water in thick leaves. They prefer dry climates and thrive in rock gardens. Sedum is the genus name given to a large group of succulents that are well-suited to container gardens. Sedum planters consider the plant's root structure, height and drainage requirements. Once these criteria are met, growers are only limited by their imaginations.
Factor a sedum's mature dimensions into your planter selection. Sedum hybrids have varied growth habits. Autumn Joy grows upright and can reach 24 inches in height. Deep planters allow roots to penetrate farther into the soil, and the large soil volume makes tall sedums less likely to topple in a strong breeze.
Wide planters as short as three inches deep are suitable for low-growing and prostrate sedums. Angelina grows only to be six inches tall and 12 inches wide. Sedums in shallow planters dry quickly and require frequent small doses of water to thrive. Wet the entire soil surface, and use caution to prevent damage to fragile roots.
Sedum planters must have excellent drainage or the plants succumb to rot. Make sure that every sedum planter has a drainage hole and that it is not clogged. Quick-drying potting mixes are available for succulents like sedum, but perlite can be added to regular potting mix for equivalent drainage and soil aeration. Follow label recommendations for proportions.
Different Planter Features
Unfinished clay pots are good sedum planters, because they are porous. Moisture is wicked away from plant roots making rot unlikely. Watering, however, must be done more frequently to prevent sedums from drying out entirely.
Plastic sedum planters making watering tricky. The top few inches may appear dry. Deep down, however, the soil can still be very wet. Tilt a plastic planter so that the bottom is visible, and stick a finger into the drainage hole. If it is very damp, give smaller amounts of water less frequently.
Glazed ceramic planters fall in between plastic and clay as far as moisture retention. The size of pot is more important than the fact that it is ceramic. Larger pots take much longer to dry out.
If you are planning to move your sedum planter indoors or to a sheltered area during the winter, choose light-weight planters made of Styrofoam. You can also place your plant on a dolly so that it can be rolled to a different location with ease.
Anything with a drainage hole can be transformed into a sedum planter. If it doesn't have a drainage hole, you can easily make one. Flea markets are abundant sources for metal bowls, colanders, cups and wooden boxes. Even an old shoe or hat can look elegant with sedum trailing over its edges.
