Understanding Colorado’s Climate
Before we dive into the lawn fertilizer schedule, let’s take a look at Colorado’s climate. Colorado is known for its extreme weather conditions, which can be challenging for lawn care. The state’s climate is considered arid, with hot summers and cold winters. The eastern part of the state is known for its low humidity levels, while the western part receives more precipitation.
The best time to fertilize your lawn in Colorado is during the cool season. The cool season starts in late summer and continues through early spring. During this time, the soil is moist, and the temperatures are mild, making it the perfect time for the grass to absorb the nutrients from the fertilizer.
The Fertilizer Schedule
Now that we have an understanding of Colorado’s climate let’s take a look at the lawn fertilizer schedule. The fertilizer schedule is divided into two parts: the cool season and the warm season.
Cool Season Fertilizer Schedule
The cool season in Colorado starts in late summer, around mid-August, and continues through early spring, around mid-April. During this time, the grass is actively growing, and the roots are absorbing the nutrients from the soil.
Here is a breakdown of the fertilizer schedule for the cool season:
Late Summer (August to September): During this time, you should apply a fertilizer that is high in nitrogen to promote root growth. The recommended amount of nitrogen is 1 pound per 1,000 square feet. You can use a fertilizer with a ratio of 3-1-2, which means it contains three parts nitrogen, one part phosphorus, and two parts potassium.
Fall (October to November): During the fall, you should apply a fertilizer that is high in potassium to promote root growth and winter hardiness. The recommended amount of potassium is 1 pound per 1,000 square feet. You can use a fertilizer with a ratio of 0-0-25, which means it contains no nitrogen, no phosphorus, and 25 parts potassium.
Winter (December to February): During the winter, you do not need to fertilize your lawn. The grass is dormant, and the roots are not actively growing.
Early Spring (March to mid-April): During the early spring, you should apply a fertilizer that is high in nitrogen to promote new growth. The recommended amount of nitrogen is 1 pound per 1,000 square feet. You can use a fertilizer with a ratio of 3-1-2, which means it contains three parts nitrogen, one part phosphorus, and two parts potassium.
Warm Season Fertilizer Schedule
The warm season in Colorado starts in mid-April and continues through mid-August. During this time, the grass is actively growing, and the roots are absorbing the nutrients from the soil.
Here is a breakdown of the fertilizer schedule for the warm season:
Mid-April to May: During this time, you should apply a fertilizer that is high in nitrogen to promote growth. The recommended amount of nitrogen is 1 pound per 1,000 square feet. You can use a fertilizer with a ratio of 3-1-2, which means it contains three parts nitrogen, one part phosphorus, and two parts potassium.
June: During this time, you should apply a fertilizer that is high in potassium to promote root growth and summer hardiness. The recommended amount of potassium is 1 pound per 1,000 square feet. You can use a fertilizer with a ratio of 0-0-25, which means it contains no nitrogen, no phosphorus, and 25 parts potassium.
July to August: During this time, you should not fertilize your lawn. The grass is under stress due to the hot temperatures, and fertilizing can cause damage to the roots.
Tips for Fertilizing Your Lawn
Here are some tips to keep in mind when fertilizing your lawn:
- Read the instructions: Always read the instructions on the fertilizer bag before applying it to your lawn. Follow the recommended amount and application rate.
- Water your lawn: After applying the fertilizer, water your lawn thoroughly. This will help the nutrients to penetrate the soil and reach the roots.
- Mow your lawn: Mow your lawn regularly to maintain the recommended height. This will help the grass to absorb the nutrients from the soil.
- Test your soil: It is recommended to test your soil every few years to determine the pH level and nutrient deficiencies. This will help you choose the right fertilizer for your lawn.
- Avoid fertilizing in extreme temperatures: Avoid fertilizing your lawn during extreme temperatures, either hot or cold. This can cause damage to the roots and affect the absorption of the nutrients.
