Fertilizing Begonias

Begonias need food to produce a continuous abundance of flowers throughout the growing season. The tubers need fertilizer to store nutrients for the start of the next growing season. Slow growth or lack of blossoms may be a sign that your begonias are hungry. They need fertilizer to promote healthy growth. Both newly planted and established begonias need fertilization.

How to Fertilize Plant Begonias

Most tuberous plants are not heavy feeders, but this is not true for begonias. They are heavy feeders and need fertilization regularly to thrive. Top dress in ground-grown begonias once a month with a balanced (20-20-20) slow-release granular fertilizer once a month during their blooming period. Fertilize container-grown begonias every other week with a weak solution of a balanced liquid fertilizer. 

Crispy brown spots on begonia leaves may be a sign of fertilizer burn. Skip the next scheduled fertilizer application if you accidentally overfed or applied too much.

Best Time To Fertilize Begonias:

The best time to fertilize begonias is by preparing the soil before planting them. Add compost or a granular fertilizer into the top few inches of soil or potting mix as part of the planting preparation process. Fertilize garden plants monthly and container plants bi-weekly during their flowering period.

Best Fertilizer For Begonias

The best fertilizer for begonias is a balanced 20-20-20 blend formulated for slow release. Slow-release fertilizers decrease the chance of your plants suffering from fertilizer burn.
