Keep your outdoor begonias happy!
Annual begonias (Begonia semperflorens: also known as wax begonias, or bedding begonias) are a gardener's best friend with their vibrant colours, gorgeous foliage and long blooming season! Plus, there are so many colours to choose from, you can put them anywhere in the garden. We're here to show you how to care for your begonias and keep them super happy and healthy all season long.
Do begonias need sun or shade?
Lighting: Begonia plants love morning sun and then enjoy a cooler afternoon shade. Too much direct sun all day will damage the leaves or stress out the plants and could lead to disease. This is great news though, because they can brighten up the shady spots in your garden! Of course, there are begonia varieties made for sun or for shade—check the info card on your plants to make sure.
Watering: How Often Should I Water My Begonias?
Generally, every two to four days. Keep your begonias happy with a moist environment but beware of soggy soil! These plants like to stay damp, and not dry out completely, but they hate having their roots sitting in water. Use well draining soil with some compost material, to help retain moisture. Always water at the base of the plant as they are susceptible to leaf rot and spots if the leaves get damp.
Temperature: When to Plant My Begonias?
Begonias are tender annuals, and need to be planted after the frost has ended in the Spring. They love warmer temperatures, and can be damaged when it dips below 10'C (50'F).
Fertilizer: Should I Fertilize My Begonias?
Use a balanced fertilizer mixed into the soil before planting your begonias in the garden, as well as a water-soluble fertilizer about once a month. This will keep them healthy and blooming for you all summer long!
How to Keep Your Begonias Blooming?
If you want to keep your plants continuously blooming, then don't be afraid to deadhead spent flowers as this will encourage the plant to grow new buds. Fertilizer also keeps them fed and blooming. As a bonus, these versatile plants are deer resistant so you can plant them in areas that have had problems with nibblers during the summer months.
