CONTAINER
GARDENING

One of the most exciting and versatile kinds of gardening,
one which seems to grow in popularity year after year, is container gardening.
Whether you live on a farm in the country, on a small plot of land in a suburban
subdivision or in an urban apartment, there is always room for container gardens.
And they are easy; following just a few simple guidelines will produce blooming
creations that will delight you all summer. LOCATION: Before you purchase
any plant materials, consider your location; it is one of the most important factors
for good container gardening. Plants can be grown in sun, part-sun, part-shade
or shade, so make sure the plants you purchase match the lighting requirements
where they will be planted. If you are combining different plants in a single
container or grouping several containers together at the same site, make sure
they share similar light requirements. Do not mix plants that require sun with
those that do well only in shady areas. Make sure, too, that your plants share
the same watering needs. CONTAINERS: When it comes time to select a container,
let your imagination go. Anything that has room for root growth and provides good
drainage can be made into a unique and interesting container. More common are
terra cotta or unglazed pots which come in many sizes and shapes and are usually
orange in color. The pots are heavy and dry out faster than other materials. Glazed
clay pots come in many colors and are less porous than unglazed pots thus holding
moisture better. Both types are breakable. Pots are also made from nonporous plastic
and fiberglass, which cut down on evaporation and hold moisture longer in the
soil. They are also lightweight, which makes them easier to move around. In
addition, there are wooden containers, which are usually made of rot-resistance
redwood or cedar. They are heavy, durable and do well in cold weather. Wooden
containers provide good soil insulation, keeping roots cooler and providing less
evaporation than terra cotta. Consider applying a preservativeone that will
not harm your plants--to the wood before you plant. There are also containers
made from metal, concrete, and other components that may appeal to your taste. Before
planting in terra cotta pots, soak them in water for 10-15 minutes to prevent
the clay from absorbing moisture from the soil mix. If you are using old pots,
clean them thoroughly to remove any salt deposits and rinse with a 10% bleach
solution to reduce chances of disease. Consider how the container drains, and,
if necessary, drill drainage holes in the bottom. Good drainage will eliminate
water build up in the bottom of the pot, which can lead to root rot and early
death of the plant. Also, keep in mind that smaller containers need more frequent
watering than larger ones. PLANTS: You can grow plants from seeds. If you
do, follow the care requirements on the seed packets. If you purchase potted plants,
care requirements are usually stated on the plastic stakes included with the plant.
These stakes provide the plant name and characteristics which may include lighting,
watering, width, height and fertilization requirements. Ive often kept these
stakes until the end of the season to judge how the plant has performed. Then
I have plant identification to reference to see if I want to use that same plant
in my garden again or to recommend it to a friend. SOIL: The drainage,
water-holding ability and growing conditions in a container are different from
your regular garden. Use ready-to-use potting mixes. Most contain basically the
same ingredients; perlite and/or vermiculite mixed with peat moss. Some mixes
have fertilizer added and may even have water-holding polymers which help reduce
water needs. To save time and guesswork applying fertilizer, mix slow-release
fertilizer into the soil at planting time. Make sure to follow the manufacturers
directions. When you fill your containers with potting soil, leave a one
to two inch gap for watering between the surface of the soil and the top of the
container. Do not use yard or garden soil in a container because it tends to compact
and roots cannot penetrate the soil. PLANTING THE CONTAINER GARDEN: Consider
the three basic plant shapes for a successful looking container garden: vertical,
trailing and filler plants. Vertical plants (dwarf papyrus, ornamental grasses)
are usually tall and narrow and should be planted in the center of the container.
Trailing plants (petunia, sweet potato vine) anchor the container and soften the
look. Filler plants (coleus, geranium) fill in the remaining spaces between the
vertical and the trailing plants and are usually only medium sized. Filler plants
can repeat the color of the vertical or cascading plant. When you are ready
to plant, remove your plants from their containers, set them on the top of the
planting soil and move them around until you decide where you would like to place
them in the container. I have found many prepotted plants to be root bound, so
before I plant them I usually cut or tear a scant quarter inch off the bottom
of the root ball to break up the roots and enable them to spread out in the soil.
Using your hands or a trowel, dig a hole large enough for the root of the
plant, slip in the plant and firm the soil down around it with the edges of your
finger. Bury the plant deep enough to not allow the root ball to rise above the
soil level. After planting, cover the top of the soil with mulch to help keep
in the moisture. Water thoroughly by using a sprinkler hose or watering can. To
encourage continual flowering during the growing season, cut off or deadhead flowers
past their prime. Container gardening encourages experimentation. You can
combine plants in ways that you would never think to do in a regular garden setting
because you can more carefully monitor their light, water and nutrient needs.
Planting in containers is a great way to introduce children to gardening by providing
them the opportunity to create a container for themselves or as a gift for a grandparent,
neighbor, or friend. Container gardening can do all the things that in-ground
gardening can do and even more. So why not resolve this year to plant a
container garden. With just a little bit of effort, you will be rewarded with
a beautiful garden that will bring you joy all summer long.
