Gardening Tip: Getting Rid of Black Sooty Mold

plant care

Black Is the New Orange?

Are your citrus trees black? If so, you are not alone. We’ve had an overwhelming number of customers coming in with Ziploc baggies filled with citrus leaves covered with a black film. It’s called black sooty mold and is actually caused by insects. Sap sucking insects often set up shop on the underside of leaves. When they ingest large amounts of sap they start excreting a sweet, sticky substance called honeydew. The honeydew is collected on the surface of lower leaves and that is where the sooty mold begins to grow. The treatment of the mold begins with the insect that is causing it. We recommend a few products. Horticultural Oil or Neem Oil is a good organic treatment that should eliminate the guilty insects. In extreme cases I would recommend Bonide’s Citrus Orchard Spray while still organic does contain pyrethrin which some organic gardeners try to avoid whenever possible. Whichever route you decide on to treat your citrus, we’ve got you covered.

PS. It is important to note that more often than not insects are attacking plants that are under stress. Sometimes that can be over watering, under watering or under fertilizing. After your treatment of the insect or disease is finished we always recommend regular applications of an organic fertilizer. Our favorite is seaweed. Regular applications of liquid seaweed to the roots and/or foliage will bring your plants back to optimum health and help fight off future ailments.

Azalea Lace Bug Issues?

Horticultural Oils & Insecticidal Soaps are effective in controlling the problem 

Once your azaleas are infested with the Azalea Lace Bug, you will know it! The damage is unmistakable. The leaves will look as though the chlorophyl has been sucked out of them – and actually it has. These sap sucking insects will be found on the underside of the leaf.

A great article that explains the problems & organic cures is published by Texas A&M AgriLife Extension and can be found on this link.

Horticultural oils and insecticidal soaps can be used to kill & control the lace bugs. Safer Insect Killing Soap is an OMRI listed product that is effective against aphids, leafhoppers, mealybug control, mites psyllids, sawfly larvae, soft scales, spider mites, whiteflies & other insects.


Carl Pool Root Activator

The Carl Pool Root Activator is made of natural glycosides derived from pecan shells and water. These are compounds that constitute a significant proportion of cellular and tissue contents of plants, and is a critical influence on plant root, stem and leaf development. Prevents transplant shock, stimulates fast root growth, increases root mass.

Recommended for all newly planted trees & shrubs. Available in quart or gallon sizes.



The Endo and Ectomycorrhizal Inoculant Blend of Rhizanova® Tree Transplant reduces risk of plant loss, improves plant establishment and growth, promotes water and nutrient uptake. Used at planting to inoculate trees and shrubs with beneficial mycorrhizal fungi. These are naturally occurring microorganisms that form symbiotic relationships with plants and greatly increase root surface area absorption via hyphal strands that extend beyond the plant’s feeder roots. Mycorrhizae are especially beneficial for increasing water & nutrient uptake, particularly phosphorus which has low soil mobility.
