Plant containers can be anything that holds soil! Remember: Drainage Drainage Drainage
KNOW YOUR PLANT’S MOISTURE REQUIREMENTS! Moisture-loving plants can stand in water: bacopa, peace lily, cannas. Plastic pots are good for these plants. Most plants cannot stand in water and need oxygen as much as moisture. Double pot these or use containers with several drainage holes. Dry loving plants require drainage and pots that dry out: terra cotta, or clay. Plastic is worse for these plants.
CONTAINER OPTIONS: TERRA COTTA OR CLAY • Classic choice because it is great for plant root growth: provides good air or oxygen exchange. • Heavy • Dries out quickly • Develops mold, salts etching
CONTAINER OPTIONS: PLASTIC & FIBERGLASS • Lightweight, maybe too lightweight • Hold moisture longer, maybe too long • No staining • Colorful, can be decorative and attractive
CONTAINER OPTIONS: WOOD • Minimum temperature fluctuation: good insulators • Needs replacing eventually, can last many years • Informal, natural appearance
CONTAINER OPTIONS: GLAZED CERAMIC • Beautiful • Non-porous and can be too airtight for root growth • May clash with plants flowers and foliage Phormium, New Zealand flax
CONTAINER OPTIONS: METAL • Little insulation: can be very hot or very cold, less of a problem in large containers • Can be very attractive
CONTAINER OPTIONS: STONE, HYPERTUFA TROUGHS • Heavy in weight and cost • Harder to find • Moss grows on containers • Drainage may be a problem.
Traditional Container Soil Mix: • 1 part garden soil • 1 part peatmoss(wet first: soak in a bucket) • 1 part sand • Use new soil each year.
Most people use synthetic soil. Lightweight; holds water and air; ideal for plant growth.
Cocc Coconut fiber or coir is in the ingredients.
Slow release fertilizer is in this potting soil, but in a very small amount.
Container plants need fertilizer. You can use a slow release fertilizer in the soil mix and weekly liquid fertilizer applications for actively growing flowering annuals in containers.
WATERING: VERY IMPORTANT • Daily in summer • Small and hanging containers need extra care • Type of container type makes a big difference
Pouches require lots of water. Use a piece of hose in the back of the pouch.
What plants should you use? It depends on: • Site • Personal preference • Color scheme • Purpose: food, color, hide/cover, frame, soften, attract attention
Hot sites call for careful plant selection. Purple or pink fountaingrass loves sun and warm or hot locations
Hidcote, England Fuchsia: likes cool weather and lots of moisture.
Osteospermum ‘Orange Symphony’ likes cool weather; opens with sun
PERSONAL PREFERENCE informal formal
White color theme: featherreed grass ‘Overdam’ Miscanthussinensis ‘Variegatus’, caladium and Zinnia angustifolia ‘Crystal White’
Define a bench: Plectranthus,sweet potato vine ‘Margarita’, coleus, supertunia
Containers allow you to grow plants where there is no access to the soil.
