Black Dots on House Plants: What’s the Deal?

Have you ever noticed little black dots on the leaves of your precious house plants, even on the stalks? It can be quite alarming to see these mysterious markings, but fear not! We’re here to shed some light on this issue and provide you with effective solutions.

Are They Friends or Foes?

First things first, let’s investigate these dots. Are they moving? Can you easily crush them? Do they rub off effortlessly? Is there a sticky residue around the drops or on the leaves and stems below? These questions will help us determine if you’re dealing with insects on your beloved green companions.

If the dots rub off easily and can be squished with little effort, you might have aphids on your hands. No worries, though! You can wash them off by placing your plants in the sink or bathtub and giving them a thorough rinse with a strong stream of water. Remember to repeat this process periodically to keep those pesky aphids at bay. Another safe option is to use insecticidal soap for indoor use. Simply put your plants in the sink or protect the surrounding area with an old sheet or plastic, and spray away! But if you prefer a stronger insecticide, wait for warm days to apply it outside and let the plants dry, leaving behind any unpleasant odors.

However, if the black spots don’t rub off or can’t be smashed, you may be facing a more formidable foe – scale insects. These little critters can be trickier to treat, but fear not, we’ve got you covered. Horticultural oil is a great option for dealing with these pesky pests, but do keep in mind that it may stain fabrics in your house. So, exercise caution while applying it. Before taking any action, make sure the spots are not just natural pigmentation, as some plants naturally produce such spots. Safety first!

Winter Woes: Protecting Your Tender Plants

Ah, the cold winter months can be a challenge for your tropical plants, especially when they’re surrounded by block walls and sit on cold tiles. But worry not, for we have some tips to keep them safe and sound.

When freezing weather is expected, the safest route to take is bringing your plants indoors. If it’s only for a few days, a dark room will do just fine. However, for a longer stay indoors, place them in a bright room near east- or south-facing windows to ensure they receive ample light. Don’t forget to bring them back outside when the weather warms up, but be cautious and bring them back inside if freezing nights return.

To make your plant-moving endeavors easier, consider placing larger potted plants on platforms with casters. This way, you can effortlessly roll them in and out as needed. It’s also a great trick for collections of smaller potted plants, reducing the number of trips to move your green companions. Remember to water your plants regularly, as they tend to dry out more quickly in the drier indoor environment.
