1751 – Fall and Winter Watering: During Drought

Limited summer rainfall and water restrictions can deplete subsurface soil moisture. Upon digging, people may find little moisture at 8 to 12 inch depths where most tree roots are located. Paying special attention to fall watering is important for trees to mature buds and enter dormancy in a healthy condition. Consider tree watering in addition […]

1706 – Fall & Winter Watering

In much of Colorado, winters can have extended warm, dry, windy spells. Warm winters without snow appeal to people, but cause winter drought. Trees and shrubs at risk from dry winters include recent transplants, evergreens and shallow rooted species such as lindens, birches, and Norway and silver maples. Water plants when the leaves start to […]

2129 – Winter Desiccation of Evergreens

Typical Colorado Front Range winters include periods of warm, windy, low-humidity days with no snow cover and extended dry periods. Needled and broadleaved evergreens, especially last year’s transplants, are very prone to winter desiccation (“winter burn”) under these conditions. As the plants hold their leaves, they continue to transpire which becomes difficult during warm, dry […]

2114 – Winter Browning of Evergreens

Brown evergreen needles, needle tips and branch tips are a common sight during the winter and early spring months in Colorado. These are all examples of winter injury usually caused by the drying winds, lack of snow cover, fluctuating temperatures, and low soil moisture that are typical of Colorado’s fall and winter seasons. Evergreen needles […]

Colorado’s eastern plains are a semi-arid environment. All newly planted trees and shrubs will need supplemental water. Apply as much water as the size of the pot or root ball each week. For balled and burlapped stock, apply 10 gallons of water for each trunk diameter inch. For example, give five gallons of water for […]

2028 – Overwintering Container Plants

Containerized trees, shrubs, and perennials are subject to extreme cold, drying winds, and frequent freeze-thaw cycles in Colorado winters. Extra protection and care must be provided to ensure root and crown survival. In November after soils have cooled, homeowners with large pots should choose a protected area in the garden. Sink the plants pot and […]

1556 – The Importance of Fall Lawn Watering

Lawn watering is often stopped in early fall. Conventional thinking is that because evapo-transpiration (ET) rates are low and the turf isn’t growing much, it is OK to stop watering. However, historic ET and rainfall data for most of Colorado shows a need of 0.5 to 1.0 inches of irrigation per week during September and […]

1532 – Efficient Lawn Watering

What happens to water you put on your lawn? Water can be used by plants, evaporate from the soil or percolate down through the soil to the water table. The most efficient watering system for a lawn is to water it when it is dry, not necessarily on every set number of days. Check the […]

1222 – Preparing Raspberries for Winter

Keep watering raspberries until the ground is frozen. Plants usually go dormant sometime in November and most of the leaves drop off. At this time give them a deep watering, down to the root zone, to prevent winter root and crown damage from desiccation. Mulch with dry leaves to help maintain adequate soil moisture. Prune […]
