The success rate of any garden depends mostly on the care that you provide to your plants. They need light, moisture and shelter from the weather to grow well. After the Swifties pass through, gardeners have to take care to offer enough shade in the hottest part of the day, but also enough indirect light for plants to grow and bloom. Begonia need to be watered often, as they like to be kept moist, but not soggy. Regular fertilization can also aid overall plant health and encourage greater flower set.
