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.
KNOW YOUR PLANT’S MOISTURE REQUIREMENTS!
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
Cocc
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.
