Seasonal Guides for Your CitraBlue® Maintenance
SPRING
Mowing
Keep your lawn between 2–3 inches in height with a rotary mower that has a sharpened blade. Never remove more than ⅓ of the leaf blade.
Watering
Don’t overwater. In the active growing season, CitraBlue needs about 1 inch of water a week from natural rainfall or irrigation.
Fertilization
For optimal results, feed your lawn during the spring season by applying Lawnifi Foundation, a granular fertilizer, or the Lawnifi Spring Fertilizer Box.
Weed Control
Apply a pre-emergent herbicide when soil temperatures reach 55 degrees Fahrenheit. This will prevent summer annual weeds like crabgrass and goosegrass from plaguing your lawn and garden.
Insect Control
Apply a broad-spectrum insecticide to prevent spring insects from appearing or to control any current spring insects like chinch bugs or white grubs.
Fungus Control
Apply a systemic fungicide at a preventive rate to keep disease from taking hold of your lawn. St. Augustine may be prone to gray leaf spot at this time.
SUMMER
Mowing
CitraBlue mowing heights during the summer generally range from about 2–3 inches. When mowing during the summer, never remove more than 1/3 of the leaf blade at a time.
Watering
Fertilization
For optimal results, feed your lawn monthly during the summer season by applying the Lawnifi’s Summer Fertilizer Box or apply Lawnifi Foundation once every three months. Reduce fertilizer in sunny areas to reduce thatch issues.
Weed Control
It is not recommended that you apply an herbicide at this time. Once temperatures exceed 85 degrees Fahrenheit, the herbicide will damage the grass.
Insect Control
Put down an insecticide to prevent grub worms, mole crickets, billbugs, sod webworms, fall armyworms and nematodes.
Fungus Control
Check for gray leaf spot.
FALL
Mowing
During the fall, mowing will occur less often—keeping your CitraBlue slightly higher than the regular 2–3 inch height will encourage deeper root growth which helps it survive in colder temperatures and during winter dormancy.
Watering
Water less as temperatures drop—too much water will lead to disease.
Fertilization
For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi’s Fall Fertilizer Box or apply Lawnifi Foundation once every three months.
Weed Control
Apply pre-emergent herbicides to control winter annual and perennial weeds like chickweed, henbit, Poa annua or purple deadnettle.
Insect Control
Check for and control any white grubs, chinch bugs, sod webworms, fall armyworms and mole crickets. Treat with an insecticide if needed.
Fungus Control
It’s recommended you apply a fungicide at preventative rates as this will help the grass enter colder months in a healthier condition.
A Word of Caution for Newly Sodded Lawns
A pre-emergent contains a chemical that prevents a weed from putting down roots. Because it is a root inhibitor, it can also negatively affect your new lawn, which is trying to establish itself by putting down roots. If you successfully killed and removed your old lawn, including all the weeds in it, your newly sodded lawn should have relatively few weeds. It is suggested that you hand pick weeds out of your newly sodded lawn for the first season.
