Epson Salt Spray
HOW TO APPLY EPSOM SALT TO PLANTS
• Foliar spray during the season. Add two tablespoons of Epsom salt to a gallon of water and use tank sprayer to apply the mix once a month substituting the spray for regular watering. Use one tablespoon per gallon of water if you apply Epsom salt spray more often than once a month. Begin foliar spraying when blooms first appear.
• Sidedressing during the season. Work one tablespoon of Epsom salt per foot of plant height around the base of each plant. Sidedress plants every six weeks beginning soon after leaves appear and continuing through the end harvest.
• Soil additive at planting time. Add one or two tablespoons of Epsom salt to the bottom of each hole before planting seeds or transplants.
