Begonia Maculata Polka Dot Care and Grow Guide

Begonia maculata, often known as Polka Dot Begonia, is a show-stopper with its olive green foliage and contrasting dots. It’s a houseplant that’ll get a lot of attention in your home, and it’s not too tough to care for.

We’ll go through how to maintain a Begonia maculata happily and how to deal with any difficulties that may develop in this post. We’ll give you some pointers on how to maintain them looking great so you can wow your visitors with a plant they won’t soon forget.

Begonia Maculata: An Overview

The attention-getting Begonia maculata is a popular flower right now, although it’s been around for a long time. Wightii, Clown, Spotted, or Polka Dot begonia are all names for this angel-winged cane begonia.

Silver polka dots appear painted on olive-colored leaves, crimson-colored undersides, and sprays of open bell-like red or white flowers with bright yellow centers on bamboo-looking knotty stalks make up the plant’s unique appearance. Choosing something over-the-top like this begonia is a great option if you’re looking for something different that will draw attention.

It’s called “simple” because it is, but it requires very particular humidity, light, and water conditions. You’ll have a plant that’s the envy of your neighborhood once you get it tuned in.

Light Requirements for Polka Dot Begonia

Provide a bright area for your maculata away from direct sunlight, since direct rays can fade the silvery spots or even burn the leaves. In the winter, a southern exposure is ideal; year-round, east or west windows are OK as long as they are kept out of direct sunlight. The idea is to have bright, filtered light.

The plant will endure low light if necessary, but it will not thrive in extremely dim conditions. The polka dot begonia is a shade plant in the south, but it may also be used in sunny windows with little direct morning or afternoon light in the north.

Your maculata’s leaves will lose color, become yellow, and eventually shed if it doesn’t get enough light. If the leaves are overheated, they will get burnt. Begonia Maculata Humidity

We’ll start with humidity because it’s the only factor that determines whether this plant will thrive or produce surprisingly lackluster results. They won’t die under low humidity, but they won’t thrive either. Increased ambient moisture can typically cure unexplained leaf loss and bloom failure.

Even if they don’t accentuate their maculata, those who have the most success keep its dampness high.

Basic techniques for raising humidity include grouping them with other plants and using water trays, but if your home is really dry—as most are—a humidifier is the best option. It takes a little more effort, but it will improve the health of all your tropical plants, and humidity has health advantages for humans as well.

Begonia Maculata Watering Instructions

Watering this begonia may be problematic if you don’t have the appropriate sort of soil, which we’ll cover later, but first, let’s go through the regulations.

Maculatas prefers wet soil and should never be subjected to drought, although they benefit from allowing the top half-inch of their soil to dry up before rewatering. If you keep these plants too wet, they’ll get root rot, so don’t water them while the soil is damp.

Allowing the topsoil to dry also helps to keep fungus and pests like gnats at bay. Because they don’t enjoy having their leaves wet, bottom watering is frequently suggested – but if that sounds like too much of a nuisance, their leaves are large enough to avoid if you’re cautious.

The idea is to keep an eye on their soil and water it properly after the top has dried off. They like a brief respite between waterings, but genuine stress is harmful: they should never wilt.

Begonia Maculata Soil Selection

Polka Dot begonia, like many other plants, prefers well-draining soil that retains moisture without getting wet. They thrive in mild commercial mixes, but it’s a good idea to add these adjustments to offer them the best possible conditions:

• Perlite — Perlite is a natural volcanic glass that comes in tiny white balls with a fluffy, almost Styrofoam-like feel. They perform an excellent job of keeping a soil aerated and bright, as well as insulating it from sudden temperature changes. NOTE: Perlite is not to be confused with vermiculite, which absorbs too much moisture.

• Non-toxic wood chips — A dusting of non-toxic wood chips improves aeration by creating angular space in the soil. The chips decay, but this isn’t a problem because maculatas are repotted and renewed periodically.

• Adding a modest amount of compost or inorganic fertilizer is beneficial. Don’t use as much as the package suggests; a half-handful per pot will enough. You’ll be lightly fertilizing the plant normally, so this simply adds to its fertility.

To make a springy, fluffy mix, start with a light commercial potting soil and add a few handfuls of perlite and a smaller amount of wood chips until you have a springy, fluffy mix. Consider making a large batch to store for future seasons. To keep it fresh and hygienic, put it in an airtight container.

Requirements for Temperature

If you keep them indoors, this is simply because they prefer the same temperatures that humans do. Keep them out of drafts and away from temperatures below 59°F (15°C).

They prefer temperatures of 65°F (18°C) to 86°F (30°C), but may endure higher temperatures during the day. They are hardy in USDA Zone 10 and may be grown outside. If you live in a colder climate, bring them inside before the first frost, unless you wish to free up their pot.


These plants are moderate feeders, so they’re easy to keep nourished even under intense light. The most important thing is not to go overboard: you don’t want brown tips and borders on your elegant leaves.

A balanced fertilizer with equal NPK levels is all that is required. When they’re growing, dilute it 50% and feed them every two to four weeks, then reduce it back throughout the winter.


A maculata that has been well-filled out is a stunning plant, but the bushy appearance requires some work. Because the plant prefers to focus its energy on growing up rather than out, the canes become thin and lanky. Pruning corrects this problem.

Pinching out the tips is the gentlest kind of pruning. (This phrase refers to cutting rather than pinching.) Because the cane tips produce a hormone that inhibits branching, removing them encourages bushier growth.

A quarter-inch above a leaf, make a cut. Just below the incision, a new leaf will emerge quickly. Using the same way above any leaf, you may undertake more significant plant alteration.

It’s common to prune heavily twice a year, although you may do less every few weeks as new growth starts.

Begonia Maculata Propagation Is Simple

Propagating a maculata is the only thing simpler than trimming it. There are two fundamental methods: submerging them in water or planting them directly in the ground.

Propagating By Water

Place the cutting end in a jar of water and let it soak. The stem releases rooting hormones that you don’t want to dilute, therefore small containers are better.

Propagation By Soil

A one-step approach involves dipping the end of a cutting in powdered root hormone and burying it in potting soil. 

Tips For Repotting And Planting

Repotting should be done once a year. In tiny pots, Maculatas like to be a little rootbound, but their tightly packed roots deplete the soil. Even if you’re not potting them up, they benefit from yearly soil replenishment.

Choose a hefty pot, such as terracotta or stone, because they’re prone to become top-heavy. Place their light pot inside a heavier container as an alternative.

If you’re transplanting in the same pot, loosen and remove dirt around the rootball’s edges to make place for new soil.

Diseases and Pests: It’s All About Prevention

It won’t be prone to pests or illnesses if you keep your Maculata healthy and practice basic plant hygiene—keep their leaves clean, and sanitize your instruments. Fungus and infestations linked to excessive dampness are the primary issues.

Mildew Powder

One of their most prevalent diseases is a fungal infection. Unfortunately, this hazard is exacerbated by generally healthy humid circumstances. It starts as circular areas of white powdery coating on the leaves and spreads.

Remove the infected material and treat with a fungicide—however, treatments aren’t always successful, so prevention is the best option. Before rewatering, make sure the topsoil is completely dry and that there is enough air movement.

Bacterial Leaf Spot

Leaf patches that look like pimples are caused by this condition. Pruning away the diseased regions will help to lessen the harm; highly infected plants should be securely disposed of.

Root stems

The sole cure is prevention through well-drained soil and cautious watering. The condition causes the stems to become mushy, swollen, and black.

Pythium Root Rot

Another drawback is that this illness causes roots to become yellow and lower stems to turn black. It may be prevented with careful watering (see the theme? ), as well as sanitized soil. Contaminated plants should be disposed of properly rather than composted. The illness is extremely infectious.

Whiteflies And Mealybugs

The problem with these pests is that insecticides aren’t particularly effective: you’ll kill helpful insects before you get to the pests. Whiteflies flutter about when disturbed, and these little vampires live under leaves and stem joints.

Insecticidal soap sprays and oils can be used to aid. Another option is to use a short-acting organic pesticide before releasing beneficial predators such as ladybugs to eat the remaining pests. Prepare for a siege in any case.

Begonia Maculata: Frequently Asked Questions

Is the Begonia Maculata a Toxic Plant?

The ASPCA lists these angel wing begonias as hazardous to dogs, cats, and horses. The roots contain the majority of the poisons, while the stems and leaves might irritate the mouth.

Why are the leaves on my Begonia Maculata becoming yellow?

Yellow leaves are commonly caused by overwatering, although other variables can also play a role. Chills, sickness, infestation, or under-fertilization are all possibilities, as can low light – or too much. Heat, excessive sun, or over-fertilization can create brown areas, margins, and leaf tips.

Why are my Begonia Maculata leaves falling off?

Because maculatas can be finicky, go through our care instructions. Most of the time, the humidity is insufficient. It’s possible that the air is stagnant or dirty. A prolonged ailment might be caused by heavy dirt. If all else fails, relocate it to a brighter area.

What is the best way to get a healthy Begonia Maculata?

Check the soil first: it should be light and airy, with no overgrowth of bark. A lanky plant is OK, but the leaves must be healthy and damage-free. Care should be taken with small specimens, which may be recent cuttings with few roots. To inspect the root ball, gently take the plant from its pot.
