  1. In or out of exposure to light
  2. Inconsistently watering or lack of humidity
  3. Watering over or under the water
  4. Water quality is poor
  5. Temperature stress
  6. Leaf spot disease
  7. Pests

These are the seven most frequently encountered in the field of plant care. If one of these causes make the lightbulb above your head go off read on to find out how you can help the health of your Dracaena Marginata.

1. Over or Under Light Exposure

When a person is exposed to long exposure to sunlight and sunburn, it can happen. If we don’t get enough sunlight, it could cause an Vitamin D deficit. The same principles can be applied to plants, which may sound odd considering that plants are able to produce photosynthesis.

Did you know that plants can be sunburned as well? A lot of direct sunlight could cause your plants’ leaves to be burned and cause ugly brown spots. Like humans sunscreen, it isn’t able to stop your plant from getting an unpleasant sunburn.

Dracaena Marginata’s preferred light source is indirect, bright sunlight. They are able to thrive in less light conditions, however, if you wish for the Dracaena Marginata to develop rapidly it’ll require the brightest, indirect light.

The Solution to Over or Under Light Exposure

If your Dracaena is currently in a location that has too much light exposure you might want to consider shifting it to a lower light zone. If your Dracaena isn’t expanding in its low-light zone, consider moving it to a location that receives direct, bright sunlight.

If you don’t have a different place to plant the Dracaena plant, placing an opaque curtain between your window and the plant will provide some protection and let the proper quantity of sunlight to pass through.

2. Inconstant Watering and Lack or Humidity

We’re aware of what drinking water on a regular basis can do to us, but imagine what it can do to plants. We’re able to get up and get a drink whenever we’re thirsty, however, the plants are dependent on us to provide them with the water they need whenever they require it.

The Dracaena is a fan of high humidity. The lack of humidity can cause them to dry quickly, and their leaves turn brown, which causes the leaves to curled. If you’ve noticed a slight curly appearance to the leaves of your plant it could be due to humidity. cause.

The Solution to Inconsistent Watering or Lack of Humidity

If the soil of your plant is at 75% dry, it’s time to provide it with a cup of water. By monitoring your Dracaena every 7-10 days, you will be able to stay on the same schedule with watering schedule. The schedule may change during the winter months when our homes get more humid and hot So be aware of this.

To maintain the humidity surrounding your plants, spray mist around your Dracaena during the morning. Misting in the morning can allow the excess humidity to disperse throughout the day, which could stop pathogens that cause disease from developing within your plants.

Another option is to put an under-plant pebble tray. Dracaena. Pebble trays can aid in increasing the amount of moisture within the atmosphere, which will keep your plant moist all day. Pebble tray are also less dirty, so if are looking for a less messy alternative, this is the one that is perfect for you.

3. Over or Under Watering

Many gardeners are aware that submerging can put their plants in danger However, overwatering can be equally harmful.

Although we’re focusing on brown spots in the plants mentioned, I believe it’s important to show the indications of an overwatering Dracaena to determine if that is the reason.

If you notice that your Dracaena’s leaves becoming yellow, it is an indication of excessive watering. If the brown spots on your Dracaena begin at the tips of the leaves and then begin to break or fall off, it is a sign of dehydration.

The Solution to Over or Under Watering

If you’re overwatering your plant, remove all excess water. Wait until your soil has become at least 75 percent dry before watering it again. If this doesn’t work then you could plant your Dracaena in soil that has more drainage to eliminate excess water and give the plant new life.

If you’re drowning your plant, you can move it to a different spot within your home. Sometimes, plants do not receive enough water because of excessive exposure to sunlight. If this isn’t the answer you are looking for, we have a different solution for you.

For your plant to flourish once more, you need to ensure that you water your Dracaena thoroughly once a day or once every two days until the soil is hydrated. Once the plant begins to grow it can be reduced to watering it once every seven to 10 days. Misting can also be a solution.

4. Poor Water Quality

It’s hard to believe that the quality of water could play an important role in the health of your plants. In the end, water is water, and plants require water. However, quality water is crucial for your plant’s well-being.

Dracaenas have sensitivity to salt and fluoride two chemical compounds that are commonly present within tap water. Fluoride is harmful to the Dracaenas specie “Janet Craig,” “Massangeana” and “Warneckii.” Even one milligram of fluoride could cause the leaves of your plants to appear brown on their leaves.

Salt isn’t harmful to Dracaenas However, salts that are soluble in high amounts can harm the roots. Salts be a problem for the leaves, causing burns on the tips. Salt is also able to pull away water of the root, leading to the plants becoming dehydrated.

The Solution to Poor Water Quality

If you reside in a region that is rainy this advice is ideal for you. If you can, conserve rainwater for the rainy season. It is the most pure and natural watersource, which is why it’s a great option to water your plants.

If you have a filtering system in your home, make sure to make sure you use water that is filtered to water your plants. The system filters out particles and contaminants out of the water which makes it safe to your plant.

However, not all people have access to one of these systems. If you don’t have a filtering system, allow your tap water to remain for at minimum 24 hours. The water’s location is allowed the fluorine and chlorine to evaporate and make the water safe for use.

Other options for water include the distilled water as well as water containing hydrogen peroxide. But, hydrogen peroxide water is best kept for use on a limited basis.

5. Temperature Stress

Dracaenas are exotic plants, meaning that they flourish in warm climates. The cooler temperatures result in their leaves turning brown.

If you maintain your Dracaena at temperatures ranging from 65deg-95degF (18.33deg-35degC) They are going to be happy and flourish and you’ll be able to prevent the leaves turning brown.

The Solution to Temperature Stress

Cold drafts can create temperatures stress to your Dracaena. Therefore, if you keep your Dracaena inside, make sure to avoid heating vents or cooling vents. You can also use air conditioning in order to keep an even temperature.

If your Dracaena is located outside in the sun, protect it from winds if it is less than 50 degF (10degC). If temperatures drop between 32deg and 37degF (0deg-2.77degC) be prepared that your plants will show some discoloration or decay.

If you can, plant your Dracaenas outside in areas with low winds in order to get plenty of sunlight they require. If you’re thinking of putting up an indoor greenhouse on your property then a Dracaena is a great choice.

6. Leaf Spot Disease

If you’ve noticed tiny brown spots that have been trimmed with yellow on your plant, it is a chance that your plant is suffering from Leaf spot disease.

The leaf spot disease can be described as a bacterium or fungus that attacks leaves and causes brown spots that are trimmed in yellow. The spots can vary in size, color, and shape.

The Solution to Leaf Spot Disease

If your plant is suffering from Leaf Spot Disease, you must immediately eliminate the affected leaves and separate your Dracaena from other plants.

Try a home-made solution to treat the leaf spot condition. Place one or two tablespoons of baking soda as well as one or two teaspoons of mineral oil into the spray bottle that is filled with water. Shake the solution thoroughly and spray the affected parts in the plants.

7. Pests

Pests are a regular issue for all plants, but not so often for Dracaenas. It’s still an excellent idea to be prepared in terms of the care of your plants.

Mealybugs and spider mites are among the most dangerous pests that your plants could be exposed to. The spider mites, which are tiny insects which rapidly destroy the leaves of your plants. They can be identified by the tiny webs they leave behind on your plants as well as the holes they make.

Mealybugs are found in humid and warm climates. Their feeding habits are similar to spider mites, but they do not leave webs behind.

The Solution to Pests

To stop these pests from taking advantage of your Dracaena for lunch, we suggest washing the cane and leaves of your outdoor plant regularly. If you have indoor Dracaenas it is possible to clean the leaves using a an damp cloth.

If you notice indications that the Dracaena becoming a food source for pests, you can spray it with an insecticide containing pyrethrin. Pyrethrin insecticides attack an insect’s nervous system, without causing further damage to the plant. Pyrethrin is an organic compound, which means it is more secure in comparison to other insecticides.

The USDA suggests mixing one tablespoon of dishwashing detergent with 1 cup vegetable oil to 1 cup water. Place this mix in the spray bottle, shake it thoroughly, then spray your plant using it.
