Mealy Bugs:

Mealy bugs are white, waxy creatures that live in large colonies usually on the undersides of the leaves and/or around leaf joints. The bug is about 1/10th of an inch and has the look of cotton. Similar to other pests a sure sign that your plant is infested is if you observe that the leaves of your plant seem dry or weak (dropping). If you notice those signs the first course of action would be to isolate the infested plant from all other plants within your home. After that use a strong spray bottle with water in order to try to wash off the colonies from your plant, or wipe off the infestation with cotton buds dipped in rubbing alcohol. Take note that this may not work to get rid of all the Mealy Bugs at one time, so keep the plant away from others while you monitor it for more insects. Another option is to buy the Mealy Bug’s natural predator called the Mealybug destroyer (Cryptolaemus montrouzieri) which is a species of lady bug. This is an option for heavily infested plants, but is probably not practical unless you have a large number of infested plants. Once the Mealybugs have been killed and consumed the Mealybug destroyer will die off from a lack of a food source.

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.

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.
