Advantages of Container Growing:
Sold and transplanted year-round Plants can be grown in the same
area Uniform growing medium Plants require no digging or balling
of roots Growing medium is usually lighter
than soil Container protects the root ball Growing medium is generally
sterilized Cost lower
Disadvantages of Container Growing:
Initial cost higher. Personnel must be trained in potting
technique. More water is required If plants are over wintered, some
protection must be provided Transplanting to the landscape is
more difficult for some plants because the soil less mixes
If left in containers too long, plants develop a circular pot-bound root system.
Types of Plants Grown in Containers:

Durable Insulated Good drainage Size of container Cost Appearance Shape
New Container Designs:
Field grow fabric containers
Using copper spray to stop roots growing in a circle
Pot in Pot
Growing Mixes:Good growing medium must include:
Good drainage Good aeration Hold moisture well Hold plant nutrients Have proper PH range Be sterilize of insects, weeds Be economical and easily
obtained Be consistent in quality Encourage good root
development Transplant well to the soil in the
plant’s permanent location
Planting & Container Spacing
Done by hand Some nurseries
have machines, but most don’t
Can touch each other, but don’t crowd
Watering – depends on many factors
Weather Plant growth Planting medium Kind of plant Size of container Type of container Container surface
