Chunky, well-draining mix: 1 part potting soil, 1 part perlite, 1 part orchid bark. Add some worm castings for nutrients.
Repot every 1-2 years in spring. Go up one pot size (2-3 cm larger diameter). Signs it needs repotting: roots growing out of drainage holes, water running straight through, or slowed growth.
Prune in spring to control size and shape. Cut just above a node with clean, sharp shears. Remove yellow or damaged leaves at the base of the petiole.
Terracotta pots are ideal as they allow the soil to breathe and dry evenly. Ensure drainage holes. A heavy pot helps balance the top-heavy plant.
Feed monthly during spring and summer with a balanced liquid fertilizer (NPK 20-20-20) diluted to half strength. Stop fertilizing in autumn and winter.
Keep away from cold drafts, air conditioning vents, and radiators. Sudden temperature changes cause stress and leaf curling.
East or north-facing window, or 1-2 m from a south or west-facing window. Filter direct light with a sheer curtain.
Living room or bedroom with bright indirect light. Makes an excellent statement plant in a corner near a window.
Continue summer routine. Watch for sunburn if light conditions have changed. Still good for propagation.
Growth begins to slow. Bring outdoor plants inside before night temperatures drop below 15 degrees C. Last month to fertilize.
Reduce watering frequency. Stop fertilizing. Clean leaves before the heating season starts to maximize light absorption.
Winter mode: water sparingly, increase humidity as heating dries indoor air. Check for pests which thrive in dry conditions.
Stick your finger 3-5 cm into the soil. If it feels dry, it is time to water. If still moist, wait a few more days.
Cut a stem section with at least one node and one aerial root. Place in water or moist sphagnum moss. Roots develop in 2-4 weeks. Pot up when roots are 5-8 cm long. Air layering works well for larger stems: wrap moist sphagnum around a node, cover with plastic, and wait for roots to form before cutting.
Fine webbing on leaf undersides, tiny yellow speckling on leaves
Shower the plant to remove mites. Apply neem oil or insecticidal soap weekly until gone.
Silver streaks on leaves, tiny dark insects on leaf surfaces
Isolate the plant. Apply systemic insecticide or neem oil. Remove heavily infested leaves.
White cotton-like clusters at leaf joints and stem bases
Dab with rubbing alcohol on a cotton swab. Follow up with neem oil spray. Repeat weekly.
Choose a plant with at least 3-4 healthy leaves. Check for fenestrations — more holes indicate a more mature plant. Inspect the undersides of leaves for pests. Avoid plants with yellow or brown leaves.
The holes in Monstera leaves are called fenestrations. Scientists believe they evolved to allow wind to pass through without damaging the large leaves, and to let dappled light reach the lower leaves. The Latin name 'deliciosa' refers to its edible fruit, which is considered a delicacy in its native range.
Native to the tropical rainforests of southern Mexico, Guatemala, Costa Rica, and Panama. Grows as an epiphytic climber on large trees in the understory, reaching heights of 20 m in the wild.
