Spider plants may turn brown for several reasons, even though they have an appearance that attracts many people. The reasons include; accumulation of dust on the surface of the leaves, exposure to excess sunlight, applying too much fertilizer on the plant, among others.

Despite the several reasons why the spider plants are turning brown, there are several ways of bringing them back to correct functioning. Such methods of solving the issue include; applying the recommended amount of fertilizer on the spider plants, cleaning the plant to get rid of the dust and dirt, etc.

The information below shows the root causes of the spider plants turning brown. Also, the article shows the spider plant brown tips and brown spots. Therefore, it is advisable to read the article to understand how to solve such an issue.

Common causes of spider plant brown spots and brown tips, including the troubleshooting tips

  • Bacteria cause leaf blight

Bacterial leaf blight appears as light lesions on the leaf tips that develop into brown lesions over time. Bacterial leaf spot and tip burn are characterized by yellowing of the leaf margins and browning of the edges, and it grows in hot, humid environments. Brown tips on spider plants indicate bacterial leaf blight infection.

  • Watering Mistakes

Watering is the one cultural activity that has been demonstrated to generate the most problems among all the care given to plants, especially when it’s overdone or not. Overwatering in this situation promotes waterlogging, which creates an ideal habitat for diseases like root rot to grow. When this happens, your plant will show signs of distress by becoming brown at the tips of its leaves.

Underwatering your plants will also cause your spider plant leaves to dry up, resulting in minimal water and food material movement. The leaves will continue to become brown, and if the problem is not resolved, the plant will die.

  • Sunlight level

When a spider plant is taken indoors from the outside, the shock can harm the plant leaves owing to a quick change in harsh temperatures. When shifting them from indoor to outdoor, the same thing can happen. Moving the spider plant from one extreme to the other can impede the plant’s growth.

Sunburn on the spider plant’s leaves, which appear as brown tips, can also be caused by keeping it in direct sunlight for long periods. Too much sun causes the soil to dry out quickly, resulting in flaky and dry soil. Such may cause the leaves to dry up, resulting in brown tips on the spider plant. You can gradually relocate the spider plant from one location to another to protect it from unexpected shock.

  • Chemicals such as fluorides

 Chlorides and fluorides are present in regular irrigation water in amounts ranging from 1.0 to 10 milliequivalents. It is a safe temperature range for your plants. When this quantity exceeds 20 me/l, however, a problem occurs. Fluorides are likely to develop in your spider plant after prolonged exposure to this type of water, resulting in browning.

Boron levels should be between 0.7 and 3.0 me/l in most cases; anything more will harm your plant. When it comes to brown tips on spider plants, these chemicals are primarily a fault, but overuse of fertilizers can also be a factor.

You will never see brown tips on the leaves if you give the plant enough indirect, filtered light throughout the day. Trim the brown ends and remove the entire leaf if it is severely damaged. After pruning, give the plant plenty of water and indirect light to ensure that the leaves remain green and healthy.

  • Applying too much fertilizer on the plant

Fertilizing spider plants is just as important as water and light, but the dosage is different. Most novice hobbyists make the mistake of overfeeding their spider plants in the hopes of seeing rapid growth. Please take it easy on the fertilizing, as too much fertilizer can harm the plant rather than help it grow. Over-fertilizing can cause toxicity and root damage, resulting in brown leaf tips.

The most prevalent cause of browning leaf tips is fertilization in the winter. During the winter, the plant is dormant and needs only light and water to stay healthy. Fertilizers are not required. Stop immediately and follow the appropriate directions and recommended dosage if you check your spider plant’s fertilizer demands by gradually increasing the dosage of fertilizer.

  • Humidity levels

Spider plants require a lot of water to thrive, and this is why they work so well in restrooms and other high-moisture environments. You may maintain a high humidity level by watering it regularly, combining it with other houseplants, or using a home humidifier.

Step-by-step guide of getting rid of the brown spots and tips

Step 1: Collect all materials required

The materials necessary for such activities include the following

  1. A clean water can.
  2. Recommended water. Especially rain or distilled water.
  3. Bleaching or disinfectant agents such as alcohol.
  4. A pair of pruning shears or scissors.
  5. Recommended fertilizer, especially the water-soluble fertilizer.
  6. Houseplant potting mix.

Start with the simplest and most common option, and if no change is noticeable, move on to more advanced troubleshooting. This principle is followed in the phases that follow.

Step 2: Using recommended water, flush the spider soil distilled or rainwater

Use two gallons of water per half of the soil pot to flush the soil of the spider plant. Slowly flood the soil with the recommended amount of water and leave it to drain completely. Leave it for a few moments before adding more. Continue doing so until all of the surplus water has been drained.

Step 3: Regularly water the spider plant with distilled or rainwater

At a depth of one inch, check the amount of water in the soil with your finger to see if it is damp. If it doesn’t, water it until the water runs out of the soil pot. Flood any remaining water out of the saucer.

Step 4: get rid of the brown spots and tips present on leave by cutting at an angle

Use sharp, sterile pruning scissors to remove the brown tips. To keep the leaves’ sharp tip shape, cut at an angle preventing the spread of bacterial leaf blight to parts of the plant that aren’t afflicted.

Step 5: apply recommended fertilizer

During the growing season, fertilize spider plants once every two or three months with two tablespoons of water-soluble fertilizer.

Step 6: Use a recommended soil pot

To avoid root rot, make sure you only use pot planters with drainage holes at the bottom.

Step 7: Make sure you only use pot planters with drainage holes at the bottom to avoid root rot

Step 8: Avoid watering from above

 Such accomplishes two goals: first, it inhibits bacterial leaf blights, and second, it prevents water particles from acting as magnifying glasses, scorching the leaves with direct sunlight.

Frequently asked questions:

  • Is it reasonable to altogether remove the brown tips on the spider plants?

You may cut or leave them depending on your choice since the brown spots are harmful and may fix themselves, leaving the spider plant healthy.


Although the spider plant is essential, it may sometimes have brown spots and tips for some reasons. The reasons include; exposure to too much sunlight, accumulation of dust on the surface, among others.

When taking care of the spider plant with brown spots and tips, it is essential to follow some precautions such as; avoid overwatering the plant, avoid applying too much fertilizer or unwanted fertilizer, etc. finally, be careful when handling the plants with such spots.
