Best Fertilizers for Begonias

Begonias' nutrient requirements can change depending on their age, variety, the current season, and state of health. It's also worth noting that begonias tend to respond better to fertilizer when it's poured around their base instead of when it's sprayed directly onto the leaves and branches. In fact, this can also be harmful to the plan if the fertilizer is too concentrated.

When should you fertilize begonias?

Begonias should be fertilized every two weeks for continuous blooms. It's best to start the feeding right before springtime before new growths start to appear.

Is Epsom salt good for begonias?

The jury is still out on this. While many gardeners attest to using Epsom salt on their plants to enhance their pH levels or add magnesium, it may not be ideal for begonias specifically. If your plants lack magnesium sulfate, it's better to find fertilizers sufficient in this mineral. And if the soil is too alkaline, it's best to add compost to the soil to increase its acidity.

Do begonias like coffee grounds?

Yes. Coffee grounds work great to help acidify the soil. However, it's important to know that they won't offer a permanent solution, but more so a temporary one. It's better to add compost to your soil. Doing so will prevent you from having to reapply the grounds every week or so. You can also use peat moss soil, which works wonderfully to create an acidic, well-draining mix that's perfect for begonias.

What feed do you give begonias?

Begonias are heavy feeders, so they all need fertilizer about every 2-3 weeks. For the most part, it's best to use a formula that has an NPK ratio of 10-10-10, 10-10-5, or 8-8-8, or something close to these. Keep in mind that this can vary depending on the plant's variety, age, and health.

Do begonias like acid fertilizer?

Yes. Begonias prefer soil that is acidic with a pH range of anywhere from 5.5 to 6.5. You can increase the acidity of your soil by using quality fertilizer that is slightly acidic.

Do begonias like Potash?

Potash hasn't been confirmed as a beneficial addition to begonia plant soil. However, the main ingredient in this mixture, potassium, can be useful for the begonias if they have a deficiency.

Not only is potassium useful to help plants fight disease and stress, but it can also be beneficial in deterring insects and weeds. However, if you're using this for the first time, it's best to start with a small amount to ensure that you don't overburden the plant.

Wrapping Things Up

Begonias are acid-loving plants that'll require a steady supply of fertilizer to produce full blooms and maintain their vigor. If you notice any discoloration or growth-related issues with the foliage or flowers on your plant, be sure to take a close look at the plants' soil, as this is usually the main cause of these types of health issues.
