Planting

January is an excellent time to plant trees, especially fruit trees.

Transplanting

Can be done this month with good results.

Fertilizing

No fertilizer should be applied to trees this time of year

Pest Control

Scale infestations can be sprayed with a lightweight horticultural oil – do not spray immediately before below freezing temperatures are expected. Spray several times about 10 days apart.

Pruning

Winter is the ideal time to prune both deciduous and evergreen trees. Do not prune spring flowering trees now.

Watering

Water in newly planted trees thoroughly. Established trees will normally receive enough water through rainfall this time of the year.

Planting

Container roses can be planted throughout this month.

Transplanting

Late December through early February is the best time to transplant roses.

Fertilizing

No fertilizer should be applied to roses this month.

Pest Control

Blackspot may be active if the weather is mild and the roses have not gone dormant.

Pruning

Wait until February to prune.

Watering

It is unlikely that you will need to water your roses this month unless the winter is dry. Natural rainfall this time of year is generally adequate.

Planting

It is too late to overseed and too early to spread seeds for warm weather grasses. You can lay sod during this month although it will not be green since it is dormant.

Fertilizing

If you overseeded with a cool-season grass you can apply fertilizer the middle of this month.

Pest Control

Winter weeds may be found during this month.

Mowing

Mow overseeded lawns as needed. Ryegrass is mowed to a height of 1 to 2 inches, so it should be cut when it has grown 1 ½ to 3 inches tall.

Watering

Normally cool, moist weather generally makes irrigation unnecessary during this month.

Planting

January is an excellent month for planting shrubs.

Transplanting

Shrubs are as dormant as they will get this month and that makes it an ideal time to transplant.

Fertilizing

No shrubs should be fertilized in January.

Pest Control

Winter is an excellent time to apply horticultural oil sprays to shrubs that are prone to scale. Do not spray if the nighttime low is predicted below 40 degrees.

Pruning

You may prune just about anything except spring- flowering shrubs during January.

Watering

There is generally no need to water established shrubs in January. Newly planted shrubs should be watered in thoroughly and thereafter regular rainfall should give them enough water. If a hard freeze is expected and the soil is dry, water thoroughly before the freeze arrives.

Planting

Perennials can be planted this month.

Transplanting

January is a good month to transplant perennials.

Fertilizing

Few perennials are in active growth during the winter. This is not the best time to fertilize them.

Pest Control

Insect and disease problems are a minimum this time of year.

Pruning

Cut back and remove old, dead upper portions of dormant perennials to keep your garden looking more attractive.

Watering

Cool/cold temperatures, typical rainy weather, and the dormant condition of many perennials make watering unnecessary.

Planting

You can plant cool season annuals this time of year.

Fertilizing

If cool season annuals are pale or yellow-green, you can apply a soluble fertilizer and green them up.

Pest Control

Watch for aphids if weather is mild.

Watering

If the weather is dry, water thoroughly.
