Watering and Fertilization
Watering your Begonia Semperflorens requires some finesse. You should only water the plant when the top surface of the soil is dry to the touch.
To avoid root rot, make sure excess water drains out the drainage holes, and don't let the plant sit in water. Use a rose attachment on your watering can to have more control over where you apply water.
Avoid splashing the leaves and water the soil only, as this can lead to bacteria and fungi growth. Misting is also a no-go.

Watering Requirements?
Watering is one of the trickiest parts of growing plants, but the key is to not water if the top surface of the soil is still wet.
Established plants don't need constant moisture and can even withstand short periods of drought, so give them about an inch of water per week and allow the soil to dry out slightly before watering again.
Avoid overwatering, which can lead to root rot and cause the stems to turn mushy, and make sure the pot has drainage holes so the soil doesn't become soggy.
Water container plants when the top inch or two of soil feels dry to the touch, and use a rose attachment to your watering can for greater control over where you apply water.
Don't let the plant sit in water, as this can lead to root rot, and avoid misting to prevent bacteria and fungi.
The soil should be allowed to dry slightly between waterings, and it's best to water thoroughly until the excess water drains out the drainage holes.
Any combination of porous, well-draining, and well-aerated soil will work for Begonias, as long as the pH level is between 5.8 and 6.8.

Fertilizing Frequency
Fertilizing your wax begonias can be a bit confusing, but don't worry, I've got you covered. You can fertilize them with a weak liquid fertilizer mixed in water, once every two weeks.
Some people prefer to use an all-purpose plant food, but make sure to dilute it at half strength. This will help prevent over-fertilization, which can be detrimental to your plant.
Begonia semperflorens can thrive without fertilizer, but if you do decide to use it, opt for organic options. These are absorbed by the plant slowly, which is better for its health.
When choosing a fertilizer, look for one that contains slow-release concentrations of nitrogen, potassium, and phosphorous. This will provide your plant with a steady supply of nutrients.
Remember to follow the manufacturer's guidelines and cut the concentration if you're unsure. And whatever you do, don't put too much fertilizer close to the roots, as it can damage and kill your plant.
Discontinue feeding your wax begonias in the colder months, as they don't need the extra nutrients during this time.
