Could it be directly spread around the trees base & grass around it? The trunk is approx. 18"diameter. Also very close to an asphalt driveway. We'd like to get it green again so it looks better & can maybe turn red in the fall again.
Hi-Yield Iron Sulfate can be used on trees, shrubs, and lawns to help prevent that yellow and faded-out look caused by an Iron deficiency Trees: Use 1/2 lb. for each 1 inch of trunk diameter - Spread out under branches and water in after application. Lawns: Apply 4 lbs. per 1,000 square feet, using any hand or power-operated gravity or rotary type spreader - Water in after application. Shrubs: Use 1 lb. for each 2 feet of height - Mix into the soil and water in after application. NOTE: Applications should not be made when temperatures are above 85 degrees F as burning may occur. Do not apply to drought stressed lawns and plants. Water the day before application is to be made during dry periods. CAUTION: This product may stain driveways, walks, patios, etc. Sweep off thoroughly, immediately after contact.
