Plant questions

hydrangea

What is causing spots and discoloration on my hydrangea leaves?

The shrub has a leaf‑spot disease, most likely a fungal problem made worse by wet leaves and crowded growth. Remove the worst leaves, clean up fallen ones, and keep the plant drier and better ventilated; it usually clears up without harsh chemicals.

What are the tiny red-brown specks on my new plant leaves?

Those tiny red‑brown specks and the dusty, faded look on the leaf are very likely spider mites. Keep the plant in quarantine, check the undersides of leaves with a magnifying glass, and start treating with a gentle wash and repeated insecticidal soap or neem spray.

aquarium plants

Why do my aquarium plants always look unhealthy?

The plants are in plain gravel with weak-looking light, so they’re probably starving for nutrients and possibly not getting enough suitable light. Start by improving the light and adding aquarium plant fertilizer (liquid and/or root tabs) to feed them.

Why are the lower leaves of my houseplant turning bright yellow?

The oldest leaves are yellowing from stress, usually from watering issues plus lower light. Check that the pot drains freely, empty any standing water from the saucer, then adjust watering so the top of the soil dries slightly before you water again.
