Gardening Tips and Hacks for Tuberous Begonia care

Tuberous begonia care is straightforward; simply adhere to a few guidelines. Soon, colorful, spectacular blooming bulbs will fill a pot or hanging basket, pouring color on the landscape.

Light & Temperature 

Tuberous Begonias’ native environment is very wet, and the nights are slightly cool. Tuberous Begonias are subject to arid and foggy environments. Unfortunately, begonias cannot tolerate the cold, and they die when left outdoors during the winter season. From the beginning, the bulbs will require heat quite constantly. They also need sufficient bright light when the germs start to come out. 

Buds in most begonias will start to fall when they are affected by frost. Cultivate your Tuberous Begonias somewhere with filtered light or where they can get morning light at most. Avoid placing the growing medium in an area with little light, as the plant will need sunlight to bloom. During the day, most perennials in bloom prefer a temperature range between 55 and 60 degrees Fahrenheit. You should also grow this perennial plant, far from high winds.

Soil & Transplant 

Before planting your Tuberous Begonias, you want to make sure that the soil texture is light and porous enough to allow any excess moisture to escape. The tubers must also have good air circulation. Use plain gravel, then mix it with sand for better drainage. Also, consider changing the repotting mix with some peat foam. When planting the tubers, put them into individual clay jars. The clay containers will allow water and moisture to penetrate through as they are porous, in comparison to plastic pots. 

For optimum root growth, you would like to add a serving of bonemeal. It also helps to keep your tuber begonias from delayed growth. Consider placing pebbles on the bottom of the culture jar to improve drainage. 

Watering need to Tuberous Begonias care

When watering, keep all the leaves dry. The effects of overcrowding include powdery mildew that impairs the quality of foliage and many hard-to-treat bacterial diseases. Keep the soil moist regularly, especially during the warmer months, but don’t overload it because it may cause root rot. Using drip irrigation or self-watering planters would be much safer, and both options are more likely to yield pleasurable results. 

In autumn and winter, it is typical for Tuberous Begonia to enter dormancy. Therefore, reduce watering intervals drastically when temperatures are at an all-time low. Apart from decay, too much humidity during this period will attract parasites. When using a commercial potting blend, it is essential to read the instructions on the soil label you are using and follow the recommended irrigation schedule.

Feeding is necessary for Tuberous Begonias care to grow well. Using humus-rich soil with other biological options would be an efficient way to feed your Tuberous Begonias. They do not need to be powered by synthetic fertilizers to look vibrant and colored. But, on the other hand, your begonias will probably take full advantage of the nutrients. Fertilizing in the first few weeks of spring, when new growth is about to emerge, is a good idea. 

However, you should know how it works to cultivate healthier plants. In addition, your Begonia domestic plants can benefit from many ways to make them grow to be more colorful and robust. Fertilization standards are approximately the same as those for most other flowering perennials. Therefore, an important phosphorus ratio would be necessary as your Begonias desperately need it during the flowering season.

Zones 4-7

You can seen Begonias as annuals, or you can store the tubers inside and replant them next spring. If plants are in pots, move them to a protected area before they freeze. Stop watering them and allow them to die naturally. Dig out the tubers (the stems should come off easily) and store them in peat moss or individual paper bags in a dark, frost-free location at approximately 50°F. 

Zones 8-11

In hot climates, begonias will start to go dormant in late autumn. Blossoming slows and the foliage becomes yellow.If the plants are in pots, just stop watering and move the pots to an area where the soil will remain completely dry throughout the winter. The tubers may remain directly in the jars. If your begonias are in the soil, you will need to dig the tubers so that they are not at risk of rotting during the winter. Let them dry in a secure area and keep them until spring.

When to repot Tuberous Begonias

Repotting is one of the most important steps in Tuberous Begonias care. As begonias love to be attached to the root, wait to repot until the container is full of roots. This will be clear if you carefully remove the plant from its pot. If the ground is still loose, let the Begonia keep growing. When the roots of the plant hold the entire soil, it is time for a transplant. 

A Begonia transplant does not always require a larger recipient. Sometimes a Begonia can wither and collapse. This means that the roots have begun to break down, and there is too much soil providing extra nutrients (and water), more than the needs of the plant. In this case, you will not move the Begoniato a larger pot, but instead to a smaller one.

How to propagate Tuberous Begonias

“How to propagate Tuberous Begonias?” and way to Tuberous Begonias care are always of interest to everyone when they start growing them.

Propagating by root cuttings

A common way to spread Tuberous Begonias is to plant roots. If you slim the stems when they are about 3 inches in height, you can use these cuttings. Besides, some gardeners cut a small piece of tuber with each shoot to increase the likelihood of stem rooting. However, the damage to the tuber may allow pathogenic organisms to attack the tuber. 

Before taking the cuttings, prepare what is known as a forsythe pot into which the roots: 

  • Take a 2-3 inch unvarnished clay pot and plug the drainage hole in the bottom. 
  • Fill a 10″ plastic container with vermiculite. 
  • Push the clay pot towards the bottom of the plastic pot filled with vermiculite. There should be a 3-inch wide vermiculite ring around the clay pot. 
  • Wet the vermiculite and fill the clay container with water. 
  • Cut out the stems for rooting and insert them into the damp vermiculite. 
  • Put the whole assembly in a clear plastic bag. 
  • Secure the top of the bag to keep air around moist cuttings. 
  • Put the Forsythe pot in a hot place with a shining indirect light. 
  • The clay jar is a water tank, so you won’t need to water the cuttings as long as you keep it full. 

After two or four weeks, the cuttings must be firmly rooted. Open the plastic bag a bit more every day for a few days to get the plants used to normal moisture. Then plant them in pots, harden them, and transplant them outdoors as outlined above. By September, small tubers will be formed that you should treat and store as you would for larger tubers.

Propagation by seeds

You can also multiple Tuberous Begonias from seeds, but you must launch the seeds in December or January for summer flowering. Fill the containers with a mix of fine-textured compost and water. Press the seeds on the surface of the medium and cover them slightly with countersunk sphagnum. Moisten the sphagnum with a spray, then cover with a film of glass or plastic to retain moisture. 

At a constant temperature of 70, germination usually takes about ten days, but it can take up to three weeks, particularly if the potting soil temperature is lower than 70. Leave plastic or glass for 1-2 days after germination and then remove it. 

Thin the seeds to 2 inches away. Bright light, such as from fluorescent light, is useful to produce robust seedlings. 

When they get cluttered, transplant them into bigger pots, using a porous and well-drained mixture. Harden the plants, then plant them in hanging baskets, in large containers or straight into your garden.

  • Gradually decrease watering and discontinue fertilization at the end of August. Some gardeners may choose to remove any flower buds that form in September to encourage dormancy and the storage of energy in tubers. 
  • Dig into the Begonia tubers when the leaves start to turn yellow or after the first deadly frost. 
  • Cut the stems at about five inches, and let the tubers dry inside at room temperature, out of direct sunlight, until the remaining pieces of stem are dry and loose. 
  • Remove stems and roots or earth, but do not wash the tubers. 
  • Put the tubers in a perforated plastic bag full of sphagnum or vermiculite. 
  • Store it in a cool, dark place with a temperature between 40ºC and 50ºC, much cooler than most cellars. An insulated but not heated attic or three season porch can be quite cold. A spare refrigerator can be a great place to store tender bulbs and other parts of plants similar to bulbs, such as tubers. 
  • Occasionally check for decay, softening, or wilting of tubers and discard the wrong tubers immediately. 

Why are Tuberous Begonias dying?

Tuberous Begonias dyingIn Tuberous Begonias care, you have to be very careful, but the plant is still dead. So find out why with us.

Place the plant in a part of your home that has bright but indirect light and do not water it immediately after potting. Wait a week or more to give the roots enough time to recover from the injury of pruning and replanting. 

Water the plant only when the top two inches of the ground are dry. If you touch the ground and the upper two thumbs are still moist, wait another day or two and check the ground again. 

You should pick plants that look healthy, even if you might pay more expensive than low-priced plants that aren’t as healthy. When taking your plant home, be careful not to expose it to extreme temperatures. It is normal for certain leaves of the wilting plant because of stress. It is better to prune all dead foliage.
