As you care for your plant, you’ll need to check it regularly to keep it growing in the best conditions. In this fourth installment of our series, we’ll dive into some common issues you might encounter with your houseplants and how to address them effectively. With the right tools and knowledge, you can keep your green friends thriving and happy.
Pests
Dealing with pests can be a frustrating part of plant care, but there are simple solutions you can use. For those pesky fungus gnats, watering with a 50/50 ratio of water and hydrogen peroxide can work wonders as a preventative measure. If you want to give your plants an extra boost, mix a 4:1 or 3:1 ratio of water and peroxide and spray it directly onto the leaves and stems to knock out and prevent these unwanted guests. Keep an eye on your sensitive plants when spraying the leaves – most plants love this but plants vary, and you risk burning leaves if your plant isn’t such a fan.
For other non-flying critters, you have a couple of options. You can wash your plant using the spray mixture we discussed in Part 3 of this series, or for a more targeted approach, apply isopropyl alcohol with a cotton swab directly to the affected areas. This method is gentle on your plants yet effective on pests.
Another natural deterrent is adding a few drops of essential oils to your watering can— only a couple drops to each gallon of water. This is especially handy if you purchase water in gallon jugs or collect and store rainwater. It’s a subtle way to keep pests at bay without harsh chemicals.
For a low-effort, cost-effective solution, consider using systemic granules. These are odorless, long-lasting, and require just a sprinkle on top of your soil. They’re perfect for indoor use and provide excellent prevention. However, please note that these should not be used outdoors, as they can disrupt the natural ecosystems in your yard. Outdoors, it’s best to let nature take its course and leave pests alone as much as possible.
Root Problems
Your plant’s roots are its lifeline, so keeping an eye on them is crucial. If you notice any changes in your plant’s leaves, it’s time to investigate the roots. Poor drainage in your current soil can cause roots to dissolve, signaling root rot. Don’t worry—many plants can bounce back if caught early! Repotting in dry soil is your best bet for recovery. I’ve saved numerous plants this way: simply unpot the plant, spray the roots with a 4:1 water and peroxide mix, then transfer them to dry soil in a new pot. Wait a day or two before watering to let the roots dry out and settle. They can look sad for a few more days or even a week or two, but many plants will recover when treated this way.
Another root-related issue is when your plant becomes root bound. If your plant starts looking inexplicably sad, check the roots. If you see more roots than soil, it’s a clear sign it’s time to repot. Giving your plant more space and fresh nutrients will help it perk up and thrive again in no time.
Leaf Problems
Leaves can tell you a lot about your plant’s health. If you notice crispy edges, your plant might be sensitive to minerals in your water. Switching to filtered water can make a big difference, especially for variegated leaves, which are more prone to problems in general.
Wilting leaves are another common concern. Start by checking your roots and soil dampness. For variegated plants, wilting can also stem from a lack of light—they typically need more brightness than their non-variegated cousins. If you suspect root rot or a root-bound situation, repotting is the solution.
Yellowing leaves are often a sign of overwatering. Always check your roots, as this can also indicate your plant is becoming root bound. Different plants have different needs—some prefer to dry out completely to the bottom of the pot, while others only need the top couple of inches to dry. Adjust your watering frequency accordingly, and repot if the soil stays too wet for too long.
While it seems confusing, yellowing leaves can also be a sign of under-watering. In my opinion, it’s better to under- than over-water. If you have a plant with yellowing leaves as the only symptom, try to refrain from watering for at least another day or two. If you get more symptoms like overall wilting, sagging, and dry soil, it is probably time for some water. Plants generally do better going thirsty than getting drowned, and you should see recovery within a day or two.
By staying vigilant and using these tips and products, you’ll be well-equipped to tackle common houseplant conditions. Happy planting!
