As a gardener accustomed to the hardy world of aroids and epiphytes, stepping into the begonia scene might feel like entering a more delicate realm.
Begonias are undeniably stunning, but they come with their own set of demands – particularly around watering.
For Southeast Asian gardeners, where humidity is high but rain can be unpredictable, mastering the art of begonia care can be a challenge.
However, with a little patience and attention, these plants can transform your space with their breathtaking foliage and charming blooms.
THE SENSITIVE DIVA
If aroids are the easy-going companions of the plant world, begonias are the prima donnas. They thrive when their needs are met, but one wrong move, and they’ll throw a tantrum – wilting, browning, or dramatically dying.
In tropical climates, begonias are especially sensitive to excess moisture. Heavy downpours make it all too easy to overwater them, leading to the dreaded root rot.
On the other hand, during dry spells or indoors, they sulk if they miss their regular watering, resulting in crispy leaf edges.
Yes, begonias love moisture – but not too much. Striking the right balance between damp and drenched soil is crucial. Their sensitivity is legendary, and while it’s tempting to give them extra care, that’s where things can go wrong.
Begonias seem to live by the motto: “I will die at the slightest inconvenience.”
And they don’t come alone – pests like mealybugs during rainy seasons and spider mites during dry spells always seem ready to complicate things.
To avoid issues, use well-draining potting mix and let the top inch of soil dry before watering. Outdoors, consider sheltering them from heavy rain to prevent waterlogging.
Indoors, avoid placing them near dry air or drafts. Begonias love consistency, but they certainly don’t appreciate extremes!
THE MAIN TYPES OF BEGONIAS YOU’LL FIND
Before diving into the delicate art of begonia care, it’s helpful to know the main types of begonias, each with its own charm and quirks. Whether you’re looking for vibrant flowers or striking foliage, you’ll likely encounter these popular varieties in local nurseries or markets.
Rex Begonias
Known for: Mesmerising foliage.
Growth habit: Rex begonias are prized for their dazzling, often metallic-coloured leaves that feature swirling patterns.
They’re grown more for their ornamental leaves than for flowers. Compact and low-growing, they make ideal tabletops or statement indoor plants. However, they’re not fond of excess water and need well-draining soil and indirect bright light to stay happy.
Tuberous Begonias
Known for: Showy, vibrant flowers.
Growth habit: These begonias are famous for their stunning blooms, which come in a wide range of colours – from bright reds and oranges to soft pastels.
They thrive in cooler, humid environments but aren’t fans of heavy rain. Tuberous begonias grow upright or trailing, making them perfect for hanging baskets or patio displays.
Once their blooming season ends, they go into dormancy, with their tubers storing energy for the next growth cycle.
Fibrous Begonias (including Cane Begonias)
Known for: Resilience and continuous blooming.
Growth habit: Fibrous begonias are the tough, reliable type, often used for garden borders or as bedding plants.
Wax begonias, a subset of fibrous begonias, bloom consistently in bright, indirect light and can handle varying weather conditions.
Cane begonias, with their tall, bamboo-like stems and small but vibrant flowers, grow upright and can reach impressive heights with the right care. Best of all, they’re more forgiving than some of their fussier relatives.
Rhizomatous Begonias
Known for: Unique leaf textures.
Growth habit: Rhizomatous begonias are known for their creeping rhizomes and fascinating leaves, often hairy or textured.
They tend to sprawl outwards, making them great for hanging baskets or as ground cover in tropical gardens.
Like their rex cousins, they require good drainage and thrive in humid environments with filtered light. Begonias might feel like a new challenge – but it’s one that’s well worth the effort.
Their sensitivity to moisture can be overcome with careful attention, and the reward is a stunning plant with intricate, colourful foliage and blooms that add elegance to any space.
So if you’re ready to expand your gardening horizons, give begonias a chance.
Their beauty, combined with the joy of watching them thrive in our tropical climate, will surely make the effort worthwhile. – Wardi Wasil
