Know the nursery
When you shop for plants, select ones that look healthy and well potted. Plants with new flowers and buds are your best bet. Avoid: spindly plants; plants with broken stems or leaves caused by rough handling; plants with roots poking out of the bottom of the pot; and plants with yellow, brown, wilted or blotched leaves.
Watering rule of thumb
Stick your finger into the soil 2,5cm deep – it should feel moist, not soggy or parched. Yellowing leaves could be a sign you’re overwatering the plant; brown tips could mean it’s not getting enough water.
Clean leaves = Happy plants
Dust on leaves blocks light and hinders photosynthesis. The simple fix: If you see a film on the leaves, hose the plant off with lukewarm water in the sink or shower, or wipe the foliage with a damp cloth. In the case of fuzzy-leaved plants, gently sweep off dust with a soft brush.
