Cat Palm

Palm Aphids:

Most Aphids are commonly known as the greenfly or black fly, and theyare one of the most common pest for indoor houseplants. The Palm Aphid is unique in the fact that the female doesn’t move and forms a distinctive ring of white wax around its body. They are not likely to kill your plant but these sap-sucking insects will infest the younger leaves of the palms as well as excrete a sugary waste product called “honey dew’. This waste often attracts the “sooty mold” fungus to those leaves.

Spider Mites:

Spider Mites look like tiny dots on the underside of your plant leaf. They usually live in large groups, so you will definitely see more than one of these tiny dots in a group on the plant. Spider Mites are known as such from the silk webbing that they leave behind on infested leaves. This presence of webbing is the best indication that your plant may be infested. Another good indication that your plant might be infested with this pest or another is by studying your plants leaf. If you begin to notice the leaves are covered a lot of yellow pin pricks that may be a good indication.

Spider mites usually become a problem on outdoor plants after certain insecticides have been sprayed that may have killed the natural enemies of the mite. The best thing to do when dealing with Spider Mites is to find an insecticidal soap that you can use to wipe down the leaves. It is advised that you test out the insecticidal soap on a small portion of the plant before applying it to the whole plant. For indoor plants the best course of action is to remove or isolate the plant from the home to minimize possible spreading to other nearby plants. If only a small portion of the plant is infested, clip that section and dispose of the clippings. If the entire plant is infested and the plant holds no sentimental value best thing to do is dispose of the plant. If you want to try and save the plant do not waste your time with pesticides as they usually won’t have any effect on this pest. Treat the plant with an insecticidal soap every couple of weeks to help kill or keep the mites in control.

Scales:

There are many species of scales that are commonly found in indoor house or greenhouse plants. Some species of the insect can have an armored shell like covering that will protect its entire form while others will have none at all. Those with the waxy shell can have its protection removed by simply scraping it away. It is easiest to tell the difference as the soft scales (no armored protection) produce honeydew while the armored scales will not. Scales feed on your plant by sucking on the plant’s sap. This will promote poor growth which will eventually stunt the growth of your plant. It can also lead to your plant being infested to sooty mold.

The most practical thing to do for your first attempt at cleaning up your plant from its infestation is to use soap and water to wash off the leaves and stems. If your plant is heavily infested, you can try an insecticide spray schedule on your plant that involves 2 to 3 sprays a week every two weeks. It is usually best to discard the plant however before the infestation can spread.

Potassium Deficiency:

Symptoms of Potassium deficiency vary among plant species, but always appear first on the oldest leaves. Older leaflets of some palms are mottled with yellowish spots that are translucent when viewed from below, followed by the leaves rolling and giving a burnt look (necrosis) from the tip inward. In other plant varieties symptoms of Potassium deficiency are older leaves that appear withered and frizzled with yellow tips and brown margins. Yet in other cases symptoms appear on older leaves as marginal or tip necrosis with little or no yellowish spotting present. When left unaddressed it will progress from the older leaves to the younger leaves, eventually killing the plant. Potassium is responsible for chlorophyll formation which plays an important part in the strength of cells, in turn enhancing the ability of the plant to resist plant diseases, insect attacks and cold conditions. The best way to take care of Potassium deficiency is to use a fertilizer that contains Potassium Sulfate. A note of caution though; an excess of Potassium may tend to delay maturity.

Magnesium Deficiency:

Magnesium deficiency can first be detected by observing the leaves of the plant as with most other deficiencies. If you notice orange/brown veins on the leaves that would be one of the first indications. This is further identified with withering or curling of the leaves which will eventually lead to the burnt look around the tips of the leaf. The best/organic way to treat this deficiency is to take Epsom salt and mix it in with about 2 gallons of water. After doing so take a spray bottle and gently mist the plant a couple of times a week.

Manganese Deficiency:

If you notice that the new growth on your plant is a pale green with transverse veins, then it is most likely a manganese issue. The best way to treat this deficiency is to take manganese chelate and spray it on the leaves. After doing so take a spray bottle and gently mist the plant a couple of times a week.
