Citrus Food of course, can address the fertility. Iron sulfate or soil sulfur can address the soil pH by steering alkaline soils toward acid. Both Iron Sulfate and soil sulfur make the existing iron in the surrounding soil more available to the plant.  Iron sulfate adds additional iron for quicker nutrient uptake.

Our citrus grower recommends a little bit of citrus fertilizer each month of the year. (Calculate the annual supply of fertilizer needed for your citrus tree by reading the fertilizer bag, then divide the whole quantity by 12 to determine your monthly dose. 

We also recommend treating the soil with either Soil Sulfur or Iron Sulfate 3 times a year.  Now is an ideal time because remaining rains will carry these products down into the soil, and impending spring growth will benefit immediately from this nutrient blast. Iron Products such as Iron Sulfate help prevent yellow leaves on citrus, azaleas and camellias and also keep a lawn greener with less mowing.

Products containing iron can stain paving, we do carry non staining Iron Plus if you need to protect your patio or driveway.

pH Adjuster Plus
Plants take nutrients up from the soil most efficiently when soil pH is neutral or slightly acidic. pH Adjuster Plus when applied over the soil surface and watered in, gently acidifies the soil and allows nitrogen, iron and other essential nutrients and elements to be released for uptake by plant roots. The end result is a healthier, more beautiful plant with brighter, greener foliage.

pH Adjuster Plus
is a pelletized sulfur that is much easier to apply than more conventional soil sulfur (no annoying dust).

Almost all plants will appreciate 2 to 3 applications per year but those plants that respond most dramatically to a pH adjustment include citrus, blueberries, camellias, azaleas and rhododendrons, gardenias and other plants that develop a seasonal yellowing of the leaf related to iron chlorosis. Most likely you can think of at least one plant you have around your home that suffers from leaf yellowing. Apply and then water or time your application to let winter rains do the watering for you.

Magnesium Sulfate has also shown to have a great greening effect.  A little bit goes a long way and should only be applied twice a year; once in early spring and again in early fall.


Soil Sulfur
E. B. Stone Soil Sulfur is used for adjusting the pH level of garden and lawn soils. Sulfur is also an essential plant nutrient. It is an essential protein ingredient, helps maintain the green color of leaves and aids in the use of nitrogen fertilizer by the plant.
Contains Elemental Sulfur.

Yellow Leaves in Citrus
Restore the green color to citrus and other evergreen shrubs now.

Many Citrus as well as other acid loving plants suffer from yellow leaves now as the cool of winter wears on.  Yellowing leaves at this time of year are usually related to alkaline soils, low fertility or low levels of available iron.
