FAQs

Citrus fertilizer: when to apply it for maximum effect?

The best time to apply citrus fertilizer is in late spring or early summer, when the tree is actively growing. Citrus fertilizer can also be applied as a foliar spray. Citrus trees are very sensitive to fertilizer type or concentration changes, so it's important to follow the product label instructions carefully.

How to use fertilizer for fruit trees in containers?

Fertilizer for fruit trees in containers should be a high-quality, water-soluble product specifically designed for potted plants. It's important to follow the product label instructions carefully, as over-fertilizing can harm plants. Citrus trees, in particular, require a high dose of nitrogen, so be sure to select a fertilizer that contains a high concentration of this nutrient. Apply the fertilizer in early spring and again in mid-summer for best results.

Is Epsom salt good for orange trees?

Yes, Epsom salt is a good citrus fertilizer. It's high in magnesium and sulfur, two nutrients that citrus trees need for healthy growth. Adding Epsom salt to your citrus tree's watering can help improve its health and yield larger, juicier fruits.

To apply Epsom salt, mix 1 tablespoon of salt into half gallon of water. Apply the solution to your citrus tree's roots once every two weeks. Be sure to follow the package directions for the best results.
