Is Your St. Augustine Turning Yellow? It could be Chlorosis.
Is your lawn St. Augustine lawn turning chartreuse or yellow? With the higher temperatures of summer, a common issue in St. Augustine lawns is chlorosis. Chlorosis is a lack of chlorophyll caused by a deficiency of much-needed nutrients such as Nitrogen and Iron. When soil temperatures and pH are too high, it’s difficult for lawns to take up these nutrients, even if they are available in the soil. Soil compaction and poor soil health also contribute to the problem.
By feeding the soil and stimulating microbial growth, your lawn can better absorb the needed nutrients, even during the summer months. Adding organic matter can help bring down the pH a bit, which helps with nutrient uptake. If you are a Soil Building Program customer you’ll receive balanced feedings year-round
Our May-June lawn treatments are filled with liquid bio-stimulants, worm castings and micronutrients will help keep your lawn and landscape healthy and well-fed
In June-July, we add a dry organic fertilizer that will continue to feed the turf to alleviate any deficiencies that might persist through summer
Aerating soil is another great way to reduce soil compaction and boost microbial activity. Soil microbes break down organic matter and make nutrients available to your plants
If you are attempting to heal your chlorotic lawn yourself, we recommend adding a layer of acidified compost, or garden sulfur, to the area and apply liquid seaweed with added iron.
