How often should I fertilize my aloe vera plant?

Aloe vera plants should be fertilized once a year, typically in the spring. Use a balanced, water-soluble fertilizer diluted to half strength. Over-fertilizing can harm the plant, so it's important to stick to this schedule for optimal growth and health.

icon

What type of fertilizer is best for aloe vera?

The best fertilizer for aloe vera is a balanced, water-soluble fertilizer with an N-P-K ratio of 10-40-10. Organic options like compost tea or a diluted fish emulsion can also be beneficial. Avoid high-nitrogen fertilizers, as they can promote excessive leaf growth at the expense of root development.

icon

Can I use succulent fertilizer for aloe vera?

Yes, you can use succulent fertilizer for aloe vera. These fertilizers are specifically formulated to meet the needs of succulents, including aloe vera. Ensure the fertilizer is diluted to half strength to avoid over-fertilization, which can lead to root burn and other issues.

Repotting for Aloe Vera
