How to Grow Bromeliad
Guzmania lingulata
Bromeliads are striking tropical houseplants with a colourful central bract that lasts for months. They absorb most of their water through a central cup — keep it topped up with fresh rainwater and change it weekly to prevent stagnation. The soil should stay barely moist, and feeding is done by adding very diluted fertiliser to the cup. After flowering, the mother plant slowly dies but produces offsets that can be potted on.
Yearly Lifecycle
Care Essentials
Feed monthly during the growing season by adding a very diluted orchid fertiliser directly into the central cup. Stop feeding once the flower spike appears.
Watch For
- Scale insects on leaves and stems
- Mealybugs at leaf bases
- Root rot from overwatering the soil
- Brown leaf tips from fluoride in tap water

☀️ Light
Bright indirect light; no direct midday sun.
Place near an east- or west-facing window for best results. South-facing windows work if the plant is set back from the glass or filtered by a sheer curtain. Low light dulls the bract colour and slows growth.
💧 Watering
Keep the central cup topped up; soil barely moist.
Fill the central cup with fresh rainwater or filtered water and change it weekly to prevent stagnation. Water the soil only when the top centimetre is dry — roots absorb little compared to the cup.
🌱 Fertilizing
Monthly, very diluted orchid feed into the cup only.
Use a balanced orchid fertiliser at a quarter of the recommended strength and apply it directly into the central cup during the growing season (spring to early autumn). Stop feeding once the flower spike emerges.
✂️ Pruning
Remove dead or browning leaves at the base.
Use clean scissors to cut away any yellowed or brown outer leaves close to the base. After the central bract fades, cut the spent flower stalk down to the base to keep the plant tidy while the pups develop.
🌿 Humidity
Prefers moderate to high humidity; mist occasionally.
Bromeliads are tropical plants that appreciate 50–60 % relative humidity. In centrally heated homes, stand the pot on a pebble tray filled with water or mist the foliage lightly in the morning to raise ambient humidity around the plant.
Growing Tips
Use rainwater or filtered water
Tap water contains fluoride and chlorine that cause brown leaf tips. Always use rainwater, cooled boiled water, or filtered water in the central cup and for soil watering.
Change the cup water weekly
Stagnant water in the central cup quickly becomes a breeding ground for bacteria and fungus gnats. Tip it out and refill with fresh water every 7 days.
Bright indirect light is key
Bromeliads thrive in bright, indirect light — a spot near an east or west-facing window is ideal. Direct midday sun scorches the leaves, while deep shade prevents the bract from developing its full colour.
Offsets are the next generation
After the mother plant flowers it slowly dies, but it produces side offsets (pups) at the base. Wait until a pup is at least a third the size of the parent before detaching and potting it on into free-draining compost.
Pests & Diseases
Pest Scale Insects
Identification: Brown or tan shell-like bumps on leaves and stems, often with sticky honeydew residue beneath.
- Remove by hand with a cotton swab dipped in rubbing alcohol.
- Wipe leaves with a soft cloth and diluted neem oil solution.
- Apply a systemic insecticide containing imidacloprid as a soil drench.
Pest Mealybugs
Identification: White cottony masses at leaf bases and in the central cup, often accompanied by sticky deposits and slowed growth.
- Dab individual insects with a cotton swab soaked in isopropyl alcohol.
- Spray with insecticidal soap solution, avoiding the central cup.
- Use a spray containing acetamiprid, covering all leaf surfaces and crevices.
Pest Fungus Gnats
Identification: Tiny dark flies hovering around the compost surface; larvae are small white grubs that damage roots in overwatered compost.
- Allow the soil surface to dry between waterings to break the lifecycle.
- Apply a biological control such as Steinernema feltiae nematodes to the compost.
- Drench the compost with a pyrethrin-based product labelled for soil insects.
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Soft, mushy, discoloured roots; yellowing or browning of lower leaves; plant becomes loose in its pot.
Treatment: Remove the plant from its pot, cut away all rotten roots with sterilised scissors, dust cuts with cinnamon or sulphur powder, and repot in fresh free-draining compost.
Prevention: Keep the compost barely moist and never allow the pot to sit in standing water. Water soil sparingly — most hydration should come via the central cup.
Disease Fungal Leaf Spot Helminthosporium spp.
Symptoms: Brown or tan circular spots with a darker border appearing on leaf surfaces, sometimes with a yellow halo.
Treatment: Remove affected leaves, improve air circulation, and avoid wetting the foliage when watering. Apply a copper-based fungicide if the infection spreads.
Prevention: Water only into the central cup and onto the soil surface, not over the leaves. Ensure good air movement around the plant.
