**Title: Best Fertiliser for Cactus – A Complete Guide to Healthy Growth**
Cacti are hardy, drought-tolerant plants that require minimal nutrients to thrive, but the right fertiliser can significantly boost their health, colour, and flowering potential. The best fertiliser for cactus is one that is **low in nitrogen and higher in phosphorus and potassium**—such as an **NPK ratio of 2-7-7 or 1-2-2**. Too much nitrogen can lead to weak, leggy growth and root rot, while phosphorus and potassium promote strong roots and vibrant blooms.
Choose a **water-soluble fertiliser** specifically formulated for cacti or succulents. Always **dilute it to half or quarter strength** and apply during the active growing season (spring to early summer). Over-fertilising is a common mistake, so feeding once every 4–6 weeks is usually enough for outdoor plants. For indoor cacti, a **monthly feeding** works well if they continue growing through the year.
Organic options like **worm castings tea, seaweed qqdewa extract, or compost tea** can also be effective, offering a slow release of nutrients without the risk of chemical burn. Whether using organic or synthetic fertilisers, remember to water your cactus before and after feeding to prevent salt buildup and root damage.
Using the right fertiliser helps your cactus stay compact, colourful, and healthy all year round.
