Month-By-Month
Gardener's Guide
- Plant
or transplant woody plants such as trees or shrubs. Now, while it
is cool and plants are somewhat dormant, is one of the best times
of the year for planting. Newly planted or transplanted material
will still need water through the winter. Don't forget to irrigate
if rainfall does not supply plenty of water. January is also a good
time to plant fruit trees.
- Bare
root roses and many of the spring flowering bulbs can also
be planted in January. Tulips and hyacinths should be pre-chilled
for 6-8 weeks in your refrigerator before planting.
- January
is also a good time to plan this coming year's vegetable garden.
Seeds and transplants can be ordered if not available locally.
- If
you have not already done so, don't forget to take soil samples
for your garden and lawn areas.
February
- February
is an excellent time for pruning. Fruit trees, grape vines, roses,
and crape myrtles should be pruned. Most evergreen plants can also
be pruned. For spring flowering plants, such as azaleas, wait until
after they bloom before prunning. Pruning now can reduce flower
production.
- In
the vegetable garden, plant English peas, Irish potatoes, beets,
carrots, lettuce, mustard, radishes, turnips, onions, asparagus
and spinach.
-
Pre-emergence herbicides for weed problems in turf can be applied
at this time. Be sure to follow label directions.
- Most
fruit trees and pecan trees can be fertilized in early to mid-February.
Do not apply fertilizers to warm season lawns or ornamental plants
at this time.
March
- Repot
houseplants where needed.
- If
you have not already done so, prune crape myrtles and overgrown
evergreen shrubs. Mulch around shrubs and trees and replace existing
mulch as needed.
- Prepare
a plan for planting spring and summer annuals. You can continue
to plant new shrubs and trees in the warm spring weather. The sooner
in spring you plant, the better, so plants will face less heat stress.
- Fertilize
trees and shrubs as needed. Roses will need monthly fertilization
through spring and summer. Fertilize fescue lawns only at this time.
Wait until two weeks after greened upbefore fertilizing warm season
grasses.
- If
lawn areas are compacted, now is a good time to aerate the lawn
using a core-type lawn aerator to help improve drainage and loosen
soils.
April
- Prune
flowering shrubs such as quince, spirea and forsythia after blooming.
- Prepare
beds and plant annual flowers.
- Lawn
areas can still be planted from seed, plugs, sprigs or sod. Fetilizer
can be applied to lawn areas provided it has been two weeks since
the grass has greened up.
- In
the vegetable garden, plant tomatoes, beans, cucumbers, squash,
butterpeas, eggplant, peppers, okra and sweet potatoes.
- As
you begin mowing the lawn, sharpen the blades every 4-6 weeks.
May
- You
may continue to plant shrubs in the landscape, but plan to water
regularly to insure that they survive the coming warmer temperatures.
- Warm
season lawn grasses, such as Centipede, St. Augustine, Zoysia and
Bermuda can still be planted during May. Pay careful attention to
watering since temperatures will continue to rise throughout the
month.
- Fertilize
St. Augustine, Zoysia and Bermuda lawn areas. Fertilizer should
not be applied to Centipede lawns at this time.
- Summer
flowering bulbs, such as dahlias and gladiolas, can be planted.
- Thin
fruit on vegetables and fruit trees.
- Don't
forget to fertilize annuals and roses monthly throughout the growing
season. Most vegetables should be side-dressed with fertilizers
at this time. Be careful not to over fertilize.
June
- Prune
azaleas and camellias after they have finished blooming.
- Spray
gardenias to control white flies and sooty mold. Crape Mrytles should
also be sprayed to control aphids and sooty mold.
- Keep
a close eye on insect problems in the lawn area. Spittle bugs and
white grubs can create serious problems in lawn areas during June.
- Warm
season lawn grasses can still be established during June. Keep a
close eye to make sure adequate water is available.
- Fertilize
St. Augustine, Zoysia and Bermuda lawn areas. Fertilizer should
not be applied to Centipede lawns at this time.
- Marigolds,
salvia, annual vinca and begonias can be planted. Pinch terminals
of flowers to promote branching.
- Don't
forget to fertilize annuals and roses monthly throughout the growing
season.
- Harvest
vegetables at peak quality. Plant beans, sweet corn, squash, okra,
and cucumbrs for a second crop.
- Watch
for disease problems in the vegetable garden. Tomatoes can be sprayed
with calcium chloride to help prevent blossom end rot.
July
- Watch
shrubs carefully for water stress. Apply adequate water but don't
overwater. Water shrubs under trees more often.
- Check
ornamental plants for insects and control as neccessary.
- Watch
for Powdery Mildew on crape myrtle and apply fungicides where damage
is severe.
- Remove
old flowers from annuals and perennials to encourage more blooming.
- Don't
forget to fertilize annuals and roses monthly throughout the growing
season.
- Fertilize
Centipede, lawns following your soil sample recommendation. This
should be your second and final application to Centipede lawns for
the year.
- In
the vegetable garden, plant beans during the first half of the month.
Now is also the time to prepare your fall garden plan.
August
- Do
not prune azaleas now. This will reduce flowering in the coming
spring. Old crape mrytle flowers should be removed as soon as their
color fades.
- Continue
to remove old flowers from annuals and perennials to encourage more
blooming. Because summer can be hard on many perennial flowers they
can also benefit from trimming back leggy growth.
- Fertilize
lawn except for Centipede grass. Lawn areas may need water during
drought. Continue to watch for insect and disease problems in turf
areas.
- Don't
forget to fertilize annuals and roses monthly throughout the growing
season.
- Plant
cabbage, collards, beets, bush snap beans, lettuce, turnips, kale,
and mustard. Carrots should be planted later in the month.
September
- Prune
ornamental shrubs for shape only.
- Divide
and transplant ornamental grasses such as liriope. Now is also a
good time to divide iris and daylillies.
- Fertilize
roses early in the month, this is the last application until spring.
- Plant
fall vegetables such as greens, onions, radishes and beets not planted
in August. Plant a cover crop of rye on unused garden plots.
- Begin
to acclimate outdoor plants to move indoors in late September. Now
is a good time to re-pot those overgrown houseplants and check for
insects.
October
- October
is the best time for planting in the landscape. Ornamental trees
and shrubs can be planted, perennial flowers can be transplanted
or divided, fall bulbs can be planted and annual flowers such as
pansies and dianthus should be planted.
- Cut
back annual and perennial flowers as they begin to fade.
- As
crops are harvested in the vegetable garden, destroy debris to prevent
the buildup of insects and diseases.
- As
leaves begin to fall, start a home compost pile to use as organic
material in next year's garden.
- October
is the perfect time to begin taking soil tests from your lawn and
garden. Remember, it takes three months for lime to react with soils.
Soil testing early gives ample time to apply lime if needed and
get your garden ready for next season.
November
- Continue
planting ornamental shrubs and trees to make new additions to your
landscape.
- Mulch
plant beds and trees with shredded fallen leaves, pine straw, compost
or other material.
- Watch
for winter weeds in turf areas as lawn areas go dormant and control
as needed.
- As
the last vegetables of the year are harvested, clean garden area
of weeds and dead crops.
December
- Continue
renewing mulch around plant beds and composting fallen leaves.
- Plant
shrubs and trees.
- Begin
working on next years garden plan.
- Till
garden soil after crops die down and remove debris from area to
prevent diseases.
- Plant
asparagus in late December.
