Because of its balanced NPK ratio, this type of fertiliser is often recommended for apple trees growing in soils that have already been deemed fairly balanced through soil testing.

Although synthetic, its balanced approach fits well into a general fertiliser schedule for apple trees, ensuring they are well-fed throughout the growing season.

Homemade Fertilizer for Apple Trees

For those who prefer a more DIY approach to gardening, homemade fertiliser for apple trees offers a cost-effective and sustainable alternative. Creating your mix from kitchen waste like banana peels and coffee grounds or yard waste like grass clippings and leaves provides essential nutrients like potassium and nitrogen. Some gardeners even use a homemade concoction of fish emulsion or bone meal for added phosphorus.

The advantage of homemade fertilisers is that they are free from synthetic chemicals, often making them a preferred choice for organic farming. Additionally, the cost is negligible since most ingredients are waste products that would otherwise be discarded. It’s an excellent option for those who want to maintain an eco-friendly garden while tailoring their fertiliser schedule for apple trees to suit their needs.

Fertiliser Schedule for Apple Trees

Understanding the right fertiliser schedule for apple trees is crucial for maximising fruit yield and maintaining overall tree health. Generally, fertilising should occur in late winter or early spring before the new growth starts. Again, it provides additional nutrients during the fruiting season in late spring to early summer. In some regions, like Kashmir, the fertiliser schedule for apple trees may vary based on local soil conditions and climate factors.

The type of fertiliser you choose—a balanced synthetic blend like 19-19-19, an organic variety, or even a homemade mix—will also influence the schedule. Slow-release options may require less frequent application, while liquid fertilisers might need to be applied more regularly for optimum benefits. In any case, a well-planned fertiliser schedule tailored to the specific needs of your apple trees is an essential component of successful apple tree care.


The health and productivity of your apple trees depend heavily on the fertiliser you choose and how you integrate it into a comprehensive care schedule. Whether you opt for synthetic options like the balanced 19-19-19 blend, prefer organic solutions such as Maxicrop Liquid Seaweed and Espoma Organic Holly-Tone, or even if you decide to go the DIY route with homemade fertilisers, each has its own set of benefits and drawbacks.
