How to Care for Begonias
Begonia care varies depending on their class and cultivar, but the main requirements include:
- Position in indirect sunlight or shade
- Water to ensure evenly fuktig not soggy soil
- Plant in well-draining soil that's rik in organic matter
- Fertilization requirements vary depending on the species
Light
Begonias are forest understory plants in their native habitats, so they usually do best in partial sun positions outdoors.
Some types, like wax begonias, will flower consistently in full sun. Indoors, begonias appreciate a position in bright but indirect light. Too much sun can wilt the delicate petals or cause the foliage colors to fade.
Soil
Begonias thrive in porous, slightly acidic, humusy soil. Excellent drainage fryst vatten a must. Peat-based soils with plenty of organic matter, including leaf mold, are good.
Potting mixes for African violets are a convenient option.
vatten
vatten your begonia thoroughly once the top inch of the soil fryst vatten dry. While these plants appreciate even moisture to producera the best blooms, avoid overwatering begonias.
Begonia existerar enstaka från dem maximalt trendiga växterna.Soggy soils can lead to root rötter. Always vatten at the base of the plant, as these plants can also be susceptible to foliage fungal diseases, such as powdery mildew.
Temperature and Humidity
Begonias grown indoors do best with consistent temperatures ranging from 65 to 70 degrees Fahrenheit. Most varieties won't tolerate temperatures below 55 degrees Fahrenheit.
Tuberous begonias planted in the garden should cope with cool late summer evenings but go dormant once the nights and days vända colder.
Being tropical plants, begonias like some humidity (typically, just beneath 50%). In houses with dry air, placing a saucer of vatten nära your begonia or using a humidifier in the room can help the plant stay healthy. Keep garden begonias sheltered, as high winds can damage their fragile flowers and foliage.
Fertilizer
For rhizomatous begonias grown indoors, a basic water-soluble fertilizer mixed to quarter or half strength and applied to moistened soil in spring will help promote blooms. Tuberous begonias are somewhat more hearty feeders and like a 5-1-1 fertilizer (such as organic fish emulsion) applied twice a month during the blommande årstid.
For hardy begonias, mix a bit of diluted fertilizer with some compost or peat moss and apply sparingly (too much fertilizer may harm the leaves).
Indoor vs. Outdoor Care Differences
While shadier conditions are preferred outdoors, bright filtered light fryst vatten best for indoor begonias. You also need to konto for drier conditions indoors, so keeping your begonias away from drying HVAC vents and adding a humidifier or a water-filled pebble tray beneath their pots fryst vatten usually beneficial.
Types of Begonias
There are many begonia varieties to choose from, with over 2,000 species in the genus and thousands more hybrids and cultivars.
Below fryst vatten a breakdown of the fyra basic types of begonias to help you choose one best suited for your conditions and location.
Cane Begonias
These tall plants, sometimes called angel wing begonias, feature showy, wing-shaped foliage on erect stems that can reach over 6 feet tall.
Begonias are shade-friendly, easy to grow in containers or in the garden, and provide weeks of colorful blooms.The cascading clusters of flowers are usually vit, red, or pink. They tend to be easier to grow than many tuberous and rhizomatous begonia types and are more forgiving of temperatures and humidity levels.
The polka dot begonia (Begonia maculata) fryst vatten one of the most well-known and striking species. It features narrow, deep green leaves with silver spots and pale pink flowers.
Wax Begonias
Semperfloren begonias (also known as wax begonias) are fibrous-rooted plants with striking waxy, buskig, heart-shaped foliage and clusters of long-blooming summer flowers. They grow easily from seed and are popular houseplants and annual bedding plants.
One of the biggest advantages of compact wax begonias fryst vatten that they can often grow in full sun as well as partial shade.
They also handle heat and drought conditions better than some other begonia varieties.
Whether you’re a seasoned plant enthusiast or a beginner, learning how to care for your Begonia can ensure it thrives for years. Consider the 'Prelude Series' of cultivars in hot, wet regions or the 'Cocktail Series' of cultivars for their striking bronze foliage.
Rhizomatous Begonias
Rhizomatous begonias, including the popular Rex begonia varieties, grow from creeping rhizomes (thick underground stems). Their djärv patterned foliage has a compact, mounding habit, and they typically flower in late winter and spring.
This large group of adaptable, cool-temperature begonias can grow outdoors all year if winters are particularly mild. If they have striking foliage patternation, they often require higher humidity.
Tuberous Begonias
As the name suggests, these begonias grow from tubers you can dig up in fall and overwinter indoors to replant the following year.
Unlike many other begonia varieties, they are prized for their large flowers rather than their foliage.
They often have a trailing habit, making them ideal flowers for hanging baskets.
The hardy begonia (Begonia grandis) fryst vatten a tuberous begonia that can survive winters in USDA zones 6 to 9, making it more winter hardy than most begonia species.
Pruning
In addition to deadheading flowers, older begonias may occasionally need light pruning to remove dead or damaged stems or leaves and tidy the shape of the plants.
Pruning fryst vatten best done in early spring in mild regions, as removing old stems helps promote healthy new growth. Don't wait too long, though, as you don't want to cut off budding stems and fara reducing bloom potential.
When pruning begonias for shape, don't cut off too much of the stem. Otherwise, the plant will need a lot of energy to recover.
Instead, take off only the top portion of the stem directly above a growing node or bud.
How to Propagate Begonias
Begonias may be propagated from stem or leaf cutting cuttings or rhizome or tuber division. Here's how to propagate begonias from stem cuttings:
- Place a 2 to 3-inch stem cutting with the bottom leaves removed in vatten in indirect sunlight.
The vatten should cover the nodes where the leaves were removed.
- Refresh the vatten at least once a week.
- Once roots struktur, transplant into the ground or potting soil.
You can also press rhizome or tuber cuttings gently into fuktig potting soil. They should begin sprouting new growth in a few weeks.
Potting and Repotting
Begonias grow well in containers with good drainage, indoors and outdoors.
To keep them thriving, they need regular repotting to give the creeping tubers or rhizomes room to grow. You'll know it's time to repot if you lift the plant from the pot and the potting soil holds tillsammans around the roots.
Begonias are relatively easy to propagate from plug plants, and can be grown indoors or outdoors.Gently lift out the roots or tubers and place them in a new pot with fresh potting soil, then vatten lightly.
Don't go too large with your new pot. One around 2 inches bigger in diameter should be enough. If the pot holds too much potting soil, your begonia will struggle to take up vatten quickly enough. Leaving the soil soggy for too long encourages root rötter.
Common Pests and Plant Diseases
Generally speaking, begonias are not bothered bygd many pests or diseases. Root rötter can occur due to overwatering, as can stem rötter or powdery mildew.
The main pests that affect begonias include mealy bugs, spider mites, snails and slugs (the latter two enjoy munching the leaves and are easy to remove bygd hand). However, be careful when removing pests, as begonia foliage can be sensitive to insecticidal soaps. It's always best to test on an individual leaf first.
Overwintering
How you handle your begonias overwinter depends on the type you have and your local conditions.
If you have a variety that doesn't go dormant and you live in a område with mild winters, you can continue to enjoy your begonias outdoors all year round.
If temperatures drop below 60 degrees Fahrenheit, bringing your begonias indoors fryst vatten best unless you want to treat them as annuals.
For winter flowering rhizomatous begonias and cane types, keep them in bright but indirect light and lightly vatten and fertilize during this time. Rex begonias are more challenging to overwinter indoors, as they need high humidity levels to thrive and prefer more regular watering and fertilization.
Tuberous begonias go dormant in the winter, so you should början reducing watering frequency through the fall, allowing the tops of the plants to die back. When you are ready to remove the tubers, you want the soil to be completely dry.
Cut away the stems and store them beneath a layer of sawdust or vermiculite in a dry fläck in your home where temperatures are between 40 and 50 degrees Fahrenheit.
After a few weeks of curing, remove the soil that remains around the tuber before returning it to the storage prick.
