What is an annual?
An
annual plant completes its life cycle in just one season, from
seed to flower to producing seeds, all before frost kills the
plant.
Most annuals are tender (killed by frost) but there are
some which are fairly hardy and will take low temperatures late
into the fall. Annuals bloom quickly from seed (that's their
schedule) and most can be planted directly outdoors.
How to use annuals in your garden Plant in large groups, or
in masses, or in rows -- whatever effect you like. Some annuals
are pretty when used as a low hedge or border around other
plants.
Annual flowers also are wonderful companions to
perennial plants, especially perennial gardens which have been
recently planted and may not bloom the same season. Plant around
mailboxes, in an old tire, or in a wheelbarrow. Annuals are
wonderful in large containers, too, and in hanging baskets.
Allow space for plants to grow (if too crowded, they can’t bloom
well). Shown above is the Easy Gold Garden, a colorful annual
flower garden from seed.
Can I plant anything else with my annuals?
YES! Combine with
spring-flowering bulbs, summer flowering bulbs, perennial
plants, blooming shrubs. They're also great combined with a lot
of other annual flowers.
Plant combinations to try (annuals in red):
Daylilies and Peonies with Daffodils, Dahlias and Marigolds,
Calendula and Nasturtiums
Hosta and Bleeding Heart with Tuberous Begonias and
Impatiens, Coleus and Pansy
Echinacea and Liatris with Lilies and Vinca, Scabiosa and
Cornflowers
Poppies and Daylilies with Tulips, Lilies and Ageratum,
Lavatera and Larkspur
Rudbeckia and Hollyhocks with Cannas, Gladiolus and Zinnias,
Verbena and Snapdragons.
Use your imagination -- Anything goes!
HOW TO GROW ANNUALS
Plan Your Garden Sketch the area on graph paper. Put groups
of similar plants together for pleasing color effect from a
distance. Allow space (one to one-half times plant height) for
plants to grow and spread.
Evaluate and Prepare Soil Select an area that's well-drained
(no puddles after rain). Improve soil by adding plenty of
organic material before establishing your garden, and do so
every year thereafter. Loosen soil by tilling or digging to a
depth of 6-12 inches. Turn over well, forking in the organic
material. If a soil test indicates, spread a balanced fertilizer
over the area, and work in. Smooth the soil surface and mark the
locations for planting. If starting a new garden in spring, wait
until your soil has passed the "clump" test. A palm-full of soil
should stick together when squeezed, then
break apart into medium-sized particles. At this point, it’s
safe to work soil.
Planting Scatter seed in bands, groups or rows, according to
packet instructions. When seedlings have several pairs of
leaves, thin then out and mulch around each plant (a 2-3 inch
layer).
Watering Water well daily, so seedlings will emerge quickly
and begin to
bloom. After plants are established, water weekly.
Possible Pest and Disease Problems
PREVENTION Pull weeds when they’re small. Deadhead (pick off
faded flowers) daily. The more you do this, the better the
plants will bloom. Pick off any dead or sick-looking leaves from
plant or ground around plant. Don’t add diseased or
insect-infested stems to your compost (they may live over
winter). Look for insects, and hand-pick them. A hard spray from
the hose will help wash off many pests. Beneficial insects
(ladybugs) and birds can help eat insect pests.
COMMON INSECTS
Aphids Small, soft-bodied, translucent insects, color green,
red, brown or black, which suck plant juices. Found on shoots,
under leaves and on flower buds. Can stunt or deform leaves or
flowers. Sticky residue ("honeydew") usually present, which
attracts ants. Control: ladybugs, strong spray from hose,
insecticidal soap.
Beetles Adults chew leaves, flowers and stems; larvae (grubs)
chew roots.
Control: Pick beetles off and knock into a can of kerosene and
water.
Caterpillars Larvae of moths and butterflies feed on leaves,
buds and flowers, mostly in spring. Buds are chewed, leaves may
be rolled up around the worm. Control: Remove affected buds and
leaves.
Mites Tiny colonies of red or brown spiders in webs under
leaves; suck plant juices and cause leaves to turn stippled,
grayish, then fall. Control: Clean up plant debris around plants
in spring. Wash off with a spray from the hose; do this daily
and try to get the underside of the leaves. Can spray with
insecticidal soap or miticide.
Whiteflies Scale-like, flat, oval pale green or brown in
nymph stage, white winged adults which fly up in a cloud the
plant is disturbed. Mottled leaves, turn yellow and die.
Control: Difficult.
COMMON DISEASES
Fungus (Powdery Mildew) White, powdery patches on leaves,
shoots, buds; stunted foliage or distorted shoots. Spread by
wind, splashing water, plant debris. Control: Remove affected
plant parts, dispose.
Fungus Diseases (Rust) Yellow dots on tops, rusty patches
underneath leaves. Spread by wind, splashing water, plant debris
from previous season. Control: Remove affected plant parts,
dispose.
Virus Diseases (Mosaic, Aster Yellows) Mottled or mosaic
patterns on leaves; stunted or distorted growth. Control: Spread
by aphids or leafhoppers. Remove and dispose of affected plants.
No real cure. Rotate your flowers around in different places
each year.
Annual Plant Care Other than removing faded flower heads and
regular watering, annuals are pretty carefree. For
early-flowering annuals, cut plants back when flowers have
stopped appearing. This will encourage new flowering. If you've
planted annuals for cutting, be sure to cut frequently because
this will encourage more flowers for future bouquets.
Enjoy!
