You are not alone: social media is full of claims that soaking banana skins in water makes a fertiliser that will give you bigger leaves and better blooms. The hack Put banana peels in a jar of water, leave them to sit, then pour the liquid on your plants. Bananas do contain potassium and small amounts of other nutrients. The snag is you have no idea how strong it is or what's missing.

The method Moisture meters measure electrical conductivity in the soil, which roughly correlates with moisture. Push the probe into the pot, around the root ball, read the dial and water only if it dips into the dry zone. Cross-check with the old tests: feel the soil, lift the pot to gauge the weight, and look at the plant itself. If the meter says dry but the soil feels cool and damp, trust your senses.

The black dots you're seeing are most likely thrips droppings. These tiny insects puncture the leaf surface to drain sap, resulting in silvery streaks, mottled patches, curling and eventual leaf drop. They thrive in warm, dry conditions and are easily introduced when plants are moved outdoors. Once inside, they spread rapidly, particularly on mature, leafy specimens. Their damage is often mistaken for nutrient deficiencies or sun scorch, but the telltale sign is the combination of silvery streaks with tiny black specks.

The plant in question isn't a true cactus at all, but a succulent called Euphorbia trigona, also known as the African milk tree. Like many columnar euphorbias, it can shoot up rapidly indoors if it's happy, often outgrowing its space. Luckily, the plant responds well to pruning if done carefully. Prescription The most effective way to manage its height is to top the plant.
