When should I repot tuberous begonias?

Keep the tubers in flats until the roots are well developed. You can transplant them in pots or flower beds when there is 4–5 inches of growth. Water them only when the soil begins to show dryness. You can water more as the plants develop.

Even if it hasn’t filled the pot with roots, repotting back into the same pot with fresh mix may give it a burst. Don’t repot a begonia into a much larger pot. Generally, move up one pot size at a time. It’s better for the plant to be repotted more frequently in smaller jumps than to make one big jump.

Likewise, what is the best potting mix for begonias? In pots, use a light free- draining potting mix containing coco coir, perlite or vermiculite (African violet mix works well). Begonias have fleshy stems and leaves that hold water for long periods of time, so they don’t need constant watering.

Similarly, it is asked, how do you transplant tuberous begonias?

Tuberous begonias grow from fleshy tubers that you can store during the winter dormant period and replant in the spring.

  1. Fill a flat with peat moss in February or March.
  2. Moisten the peat moss and place the flat in an area with indirect light, that’s between 60 and 70 degrees Fahrenheit.

Should you deadhead tuberous begonias?

do not require deadheading to thrive. Rather they self-clean by dropping spent flowers on their own. However, if you want to clean up your begonias a bit faster than nature does, or if you want to encourage the plant to produce more stems, you should get into the habit of deadheading.

How do you keep begonias blooming?

Following some general growing tips common to most begonias, however, probably will encourage your plants to bloom. Grow begonias in bright, indirect sunlight or dappled sunlight, preferably in an area with high humidity. Water begonias thoroughly when the top 1/2 to 1 inch of their soil feels dry.

How do you care for potted begonias?

Water begonias carefully. Let the potting soil dry out slightly between watering during lower light and cooler temperatures of late fall and winter. If possible, use room temperature water that has been distilled. Mist the foliage of Rex (foliage) type begonias twice a week or provide high humidity to avoid leaf drop.

How often do you water begonias?

The main rule of thumb for watering begonias is to not let the soil dry out completely. Stick your finger into the soil, and if it dry to your first knuckle, it’s time to water. Avoid overwatering, which will cause the foliage to turn yellow and eventually drop.

Can a begonia be a houseplant?

Generally, fibrous and rhizomatous begonias make excellent houseplants while tuberous begonias can be grown as houseplants but have a harder time surviving due to the need for higher humidity and light than the other two kinds. Begonias grown indoors are especially susceptible to root rot and overwatering.

Why are the leaves on my begonia turning brown?

Too much sunlight can lead to fading and wilting of the leaves, and continued excessive sunlight can cause the edges of the begonias’ foliage to turn brown. Begonia plants do not like very wet soil, and too much soil moisture can cause the plants’ roots to rot.

Does a rex begonia flower?

Tuberous: These begonias are usually grown for their showy flowers, which come in every color except blue. They vary in size and go dormant in the fall and winter months and restart each spring. Rex: Famous for their outstanding foliage, color, and texture, Rex begonias are actually a type of rhizomatous begonia.

Do begonias come back every year?

Like Impatiens, Begonias are actually tender perennials (come back year after year) that are usually treated as annuals (gone forever at first frost). In deep shade situations, Begonias will stretch and become leggy, so do give them a spot with at least a few hours of sunlight for the best results.

Why is my begonia not flowering?

The tuberous begonia suffers flower bud drop if it is overwatered or overfertilized. The plant needs moist soil that dries between waterings. This reduces disease and encourages blooms.

How do you divide tuberous begonias?

Begonia tubers increase in size each year and after three years or so, the flower display will begin to deteriorate. It’s best to divide the tubers in the early spring, after the buds have begun to swell. Use a sharp knife and divide into as many pieces as you like, as long as each piece has at least one bud on it.

Do begonias spread?

Trailing-scandent begonias grow along the ground or vine up tree trunks. They can grow from 6 inches to 8 feet or more. They form roots at the nodes and can spread over large areas. Thick-stemmed begonias develop treelike stems and in warm climates can grow 20 feet tall.

Can you replant a begonia?

Step 1 – When to Transplant For begonias kept indoors during the winter (either tuberous or in begonias in pots), transplanting outdoors after frost is gone in the spring is one way to do it. New begonia plants can also be transplanted in the fall, which gives the plants enough time to develop roots.

Can begonias be rooted in water?

begonia cutting in water But making baby begonias can be even easier if you root your cuttings in a glass of clean, fresh water. It’s fine to put several cuttings in each jar. Once the roots are about ½” long, the cuttings are ready to transplant.

Do all begonias have tubers?

Any begonias that do not have tubers or rhizomes fall into the third general category of fibrous-rooted varieties. These have ordinary root systems and include many varieties commonly used as summer bedding plants. All begonias with glossy leaves are of this “wax leaf” begonia type.

How do begonias reproduce?

A particular group of begonias, called the rex begonias (Begonia rex cultorum), propagate themselves through leaf cuttings. Unlike other plants that use specific stem portions for reproduction, the rex begonia uses its leaf veins to create new plantlets. The plant thrives outdoors in warmer Mediterranean climates.
