How do I add iron to my blueberry plants?
Apply ½ pound of sulfur per 100 square feet each March and September until the total amount has been applied. Chelated iron products may be applied to the soil to provide iron in a plant available form. However, high pH soils may prevent most iron chelates from working.
Why my blueberry leaves are turning yellow?
Blueberries in particular are highly susceptible to chlorosis, because they crave such an acidic soil. When soil pH is too high for blueberry preference, the roots cannot properly take up iron, leaving the plant deficient.
What do you use to acidify soil for blueberries?
Pure elemental sulfur, or a commercial soil acidifier containing sulfur, is the most common treatment used to acidify soil for blueberries. It's best to do this the year before you plant your berries, so there will be time for the sulfur to do its work before you actually start the bushes.
What is the best fertilizer for blueberries?
Blackberries respond well to any nitrogen-rich fertilizer, but blueberries require fertilizers with an ammonium form of nitrogen such as urea, sulfur-coated urea, ammonium sulfate, or cottonseed meal. Any fertilizer sold for azaleas or rhododendrons also works well for blueberries.
Is Epsom salt good for blueberry plants?
Epsom Options
If your blueberries need magnesium, Epsom salt grants temporary relief. In deficient soils, broadcast 1/4 cup of Epsom salt in a 10-inch diameter around the plant, and water thoroughly. ... A foliar spray gets the magnesium directly to leaves that need it most.
