2 Containers for plants can be anything!! As long as it has: Drainage!!

3 Plant containers can be anything that holds soil !! Remember: Drainage

4 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.

5 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

6 Container options: plastic & fiberglass Lightweight, maybe too lightweight Hold moisture longer, maybe too long No staining Colorful, can be decorative and attractive

7 Container options: wood Minimum temperature fluctuation: good insulators Needs replacing eventually, can last many years Informal, natural appearance

8 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

9 Container options: metal Little insulation: can be very hot or very cold, less of a problem in large containers Can be very attractive

10 Container options: stone, hypertufa troughs Heavy in weight and cost Harder to find Moss grows on containers Drainage may be a problem.

11 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.

12 Most people use synthetic soil. Lightweight; holds water and air; ideal for plant growth.

16 CoccCocc Coconut fiber or coir is in the ingredients.

17 Slow release fertilizer is in this potting soil, but in a very small amount.

18 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.

19 Watering: very important Daily in summer Small and hanging containers need extra care Type of container type makes a big difference

20 Pouches require lots of water, use a piece of hose in the back of the pouch.

21 What plants should you use? It depends on: Site Personal preference Color scheme Purpose: food, color, hide/cover, frame, soften, attract attention
