If you’ve ever spotted those cheerful, globe-shaped flowers nodding happily in the breeze, chances are you were looking at gomphrena. These sturdy little plants are fast becoming a favourite among Singapore’s home gardeners, and for good reason. Not only are they stunning in arrangements and gardens, but they’re also hardy, low-maintenance, and thrive in our tropical weather.
If you’re wondering how to care for gomphrena in a way that keeps them blooming beautifully, this guide is just the thing. Whether you're growing them in pots, balconies, or gardens, here's everything you need to know to enjoy their vibrant charm all year round.
1. Let There Be Sun
Gomphrena thrives in full sun, which means it needs at least 6 to 8 hours of direct sunlight every day. In Singapore, place your plant in a spot that gets strong morning or afternoon sun, such as an east- or west-facing balcony or garden patch. Indoors, position it near a bright window, and consider using a grow light if sunlight is limited. Without enough sun, the plant will produce fewer flowers and weaker stems.
2. Keep It Well-Drained
To prevent soggy roots, plant gomphrena in a potting mix that includes ingredients like sand, perlite, or vermiculite for better drainage. If you’re using a pot, ensure it has proper drainage holes.
In garden beds, choose raised spots that don’t flood easily during Singapore’s rainy days. Water the plant only when the top inch of soil feels dry, usually every 2 to 3 days in sunny weather, or less frequently during wet spells.
3. Feed It Right
A balanced fertiliser (10-10-10 or 15-15-15) applied once a month is enough to support healthy growth. For even more vibrant blooms, use a fertiliser with a slightly higher phosphorus content (like 10-20-10). Mix and dilute according to the instructions on the bottle, and apply in the early morning or evening to avoid any leaf burn from midday sun. Don’t over-fertilise, too much nitrogen can lead to lots of leaves but very few flowers.
4. Deadhead Regularly
Snipping off spent or dried blooms encourages the plant to grow new ones faster. Just pinch or cut off the faded flower just above the nearest healthy leaf node.
Do this weekly to maintain a tidy look and promote continuous blooming. It’s a simple and effective habit to keep your gomphrena lush and colourful.
5. Watch Out For Pests
Although gomphrena is naturally resistant to most pests, it's still a good idea to check for aphids, spider mites, or whiteflies once a week. Look under the leaves and around the stems.
If pests are found, treat the plant with a natural neem oil spray (about 5 ml of neem oil with a few drops of mild dish soap in 1 litre of water). Spray early in the morning or late in the evening when the sun isn’t too strong.
6. Trim Occasionally
To keep your gomphrena looking full and bushy, give it a light trim every few weeks. Cut back around one-third of the top growth just above a pair of leaves. This helps the plant grow more side branches, which means more flowers. Regular trimming also helps maintain a neat, compact shape, especially important for potted plants.
7. Best Grown From Seeds
Gomphrena grows best when started from seeds. Sow the seeds in small trays or pots filled with a light seed-starting mix. Press them gently into the surface (they need light to germinate) and keep the soil lightly moist.
With warm temperatures and steady moisture, seeds usually sprout in 7 to 14 days. Once seedlings develop two sets of true leaves, transplant them into larger pots or directly into the garden, spacing them 20–30 cm apart to give each plant enough room to spread and breathe.
