How to Grow Cactus & Succulents Under Lights


Citrus trees are susceptible to a variety of pests, one of which is a kind of mining insect known as a citrus leaf miner. Citrus trees are also susceptible to other types of tree diseases. These little moths have larvae that feed within the leaves of citrus trees, which may cause harm to the plants. The use of approaches that do not involve the use of chemicals is the most effective way to keep these pests at bay.

The citrus leaf miner is the sole species of mining insect that attacks citrus trees, including lemon, orange, lime, and other citrus trees, as well as allied species like kumquat trees. There are many other kinds of mining insects. The adult leaf miners are moths that are rather tiny and silver in appearance. On the surface of leaves is where the female leaf miner will deposit her eggs. After hatching, the larvae will enter the leaf, where they will produce a very thin deposit of excrement as they progress through the leaf tissue. These insects grow best when temperatures are between 70 and 85 degrees Fahrenheit.

  1. 1. Install a Grow Light

    According to the citrus leaf miner extension information provided by the University of Georgia Extension Agency, the larvae of citrus leaf miners can only enter delicate, freshly developed leaves that have not yet hardened. The deformed and curled appearance of the leaves is caused by the action of leaf miners. Citrus leaf miners are more likely to cause harm to younger trees that have less foliage than to damage more mature trees; yet, it is very uncommon for these insects to kill a tree. However, heavy infestations of leaf miners may have a negative impact on fruit yield.

  2. 2. Set Up a Reflective Surface

    Cultural activities may be of assistance in warding off citrus leaf miners and protecting valuable plants. When citrus leaf miner populations are high, the University of California Integrated Pest Management recommends avoiding the use of fertilisers rich in nitrogen. This is because nitrogen fosters young, delicate growth that may get afflicted by the larvae of the citrus leaf miner. And despite the fact that you may be tempted to remove leaves that are contaminated with citrus leaf miner larvae, it is recommended to keep them on the tree as a food source so that other healthy leaves are not targeted. This will prevent the citrus leaf miner larvae from spreading to other leaves.

  3. 3. Program a Grow Light Timer

    One time per year should be the limit for cutting healthy citrus tree branches. If you prune all of the branches at the same time, you may assure that new growth will occur at the same time. This will reduce the amount of time that leaf miners have to reproduce, which can help prevent damage to the plant. Water sprouts are another kind of shoot that may be seen growing on the branches of citrus trees. It is in your best interest to eliminate these branches since they may also house citrus leaf miner larvae.

    Even if you take preventative measures, there is always a chance that leaf miners may invade your citrus grove and cause damage. According to the University of California Integrated Pest Management, broad-spectrum insecticides are not advised for use in cases of citrus leaf miner infestations. This is due to the fact that these harsh products have the potential to kill beneficial insects, which in turn would allow other citrus tree pests to proliferate without any natural predators. Chemical treatments are often unsuccessful against citrus leaf miner larvae due to the fact that the larvae seek refuge inside the leaf tissue.

  4. 4. Check Soil Moisture

    Spinosad is an organic pesticide that may be used to treat citrus miner larvae; however, due to the poor residual action of this pesticide, it will need to be applied many times during the treatment process. In order to get the greatest possible outcomes, the Texas A&M AgriLife Extension suggests applying Spinosad to any new growth on citrus trees once every seven to 14 days. Spinosad is believed to be generally safe for beneficial insects that feed on leaf miners, as well as for bees and other types of pollinators, owing to the fact that it leaves behind very little residue.

    Empty the water from the catch basins beneath the containers. Give them a houseplant fertilizer with a balanced 10-10-10 or similar ratio diluted to one-quarter of the recommended rate at the beginning of April, mid-May and the end of June.

  5. 5. Cacti and Succulent Winter Care

    Water them only once each month in the winter. Re-pot them in the spring if they become pot-bound, roots are growing from the drain hole in the bottom of the container and the plant becomes top-heavy, advises Missouri Botanical Garden. Use a new container that is 1 inch wider than the previous container.
