Indoor Container for a Fast-Germinating Perennial Flower

Pots and Containers

• Pots and containers come in a range of stone, plastic, copper, aluminum, clay, wood and ceramic materials. Aggie Horticulture notes that clay pots offer better aeration for roots but dry quickly, while plastic and metal pots provide more moisture retention and easier maneuverability. Plastic pots are the least expensive option, but are not as attractive as decorative pots. Choose a pot per your preferences and adjust your care accordingly. Re-pot houseplants every two years, or when their roots outgrow their old pots.

Size and Drainage

• Aggie Horticulture recommends containers large enough for soil and roots, with drainage holes in the bottom. If you're re-potting a houseplant, move it to a pot one to two sizes larger than the old one. Large pots give perennials more room for root growth and establishment, while small containers bind roots and restrict growth. Choose pots that measure at least 6 inches deep and hold at least 5 gallons of soil to give plants room and balance.

Soil and Nutrition

• Potting soil is an important part of any potting process, as the perennial depends on the soil for vitamins, minerals and moisture. Aggie Horticulture recommends mixing a non-soil potting foundation with one part peat moss or pine bark to one part vermiculite or perlite. Mix a soil foundation with one part quick-draining potting soil to one part organic compost. Both foundations provide generous nutrition and moisture retention for long-term health. Purdue University's Department of Horticulture recommends adding 5-10-5 granular fertilizer to soil for perennials, to encourage quick root development.

Placement

• Aggie Horticulture calls light the most important aspect of houseplant growth. Keep the plant in bright, medium or low light, depending on cultivar needs, and use both natural and artificial light to satisfy this requirement. Maintain good air circulation and moderate temperatures for perennial germination, growth and flowering. Don't put the plant near heating registers or fireplaces as the hot, dry air dries out plant foliage and blooms.
