- PFF Gold – At the start of the cropping season, from bud burst through to mid cell division, apply PFF Gold, then transition to High K from mid cell division through to harvest; this combination helps plants effectively manage calcium uptake from the root system, when needed most.
What is a potassium-enriched plant food and how does Kendon High K benefit all plants?
Kendon High K is a versatile supplement formulated to enhance growth and vitality in fruit, vegetable, and ornamental plants. Potassium plays a vital role in plant development, boosting flower colour and longevity, improving fruit quality, and strengthening roots for better nutrient uptake. This supplement also helps plants resist disease and tolerate stress, ensuring healthy growth in various conditions. When your regular fertiliser doesn't provide enough potassium, Kendon High K offers a balanced solution for vibrant blooms and productive harvests.
What plants and crops can benefit from a liquid potassium supplement like Kendon High K?
As a versatile liquid potassium fertiliser, Kendon High K is suitable for a wide range of plants, including pome fruits (like apples and pears), stone fruits, citrus, leafy and root vegetables, as well as flowering ornamentals, lawns, and turf. Its balanced nutrient profile supports healthy growth, vibrant blooms, and robust yields across both edible and ornamental plantings.
How does potassium improve the appearance and storage quality of fruits and vegetables?
Potassium is essential for plant cell development, sugar movement, and water regulation. When applied during the growing season, this Kendon High K product is used as a vegetable fertiliser or fruit fertiliser, that helps produce fruit and vegetables with enhanced colour, firmness, and flavour, while also improving their ability to store well after harvest. This means your crops not only look better but also maintain quality for longer periods.
Can I use Kendon High K with pesticides and wetting agents for better foliar coverage?
Yes, Kendon High K can be combined with most pesticides for effective foliar application, as these often contain sufficient wetting agents. When using High K on its own, it’s beneficial to add a non-ionic agricultural wetting agent, such as Kendral 600, to ensure thorough and even coverage of plant foliage, especially on hard-to-wet plants.
Is potassium enriched fertiliser suitable for lawns and turf, and how does it help with wear resistance?
Yes, a fertiliser with a higher potassium content is effective for use on lawns and turf, promoting stronger root systems and improved resilience. Regular application of Kendon High K can increase grass resistance to wear and stress, making it ideal for sports fields, high-traffic areas, and ornamental lawns that require durability and lush appearance.
What trace elements and nutrients are included in this rich potassium supplement?
In addition to its rich potassium content, Kendon High K contains nitrogen and phosphorus for balanced nutrition. Essential trace elements are also included: boron and molybdenum (as sodium salts). Copper, iron, magnesium, manganese, and zinc - all added as chelates for instant uptake by plants. These nutrients support overall plant health, growth, and stress resistance.
How do I apply Kendon High K – by spraying, irrigation, or mixing with other products?
Kendon High K can be applied as a foliar spray or through overhead irrigation, making it easy to integrate into your existing nutrition program. It is compatible with most insecticides and fungicides, except for alkaline materials like Lime Sulphur, White Oil, or Bordeaux. Always read product restraints and compatibility notes before mixing.
What makes Kendon High K one of the best fertilisers for fruit trees in Australia?
Kendon High K is specially formulated for fruit trees, providing a high level of potassium to boost fruit size, flavour, and colour. Its balanced NPK (Nitrogen, Phosphorus, Potassium) profile and chelated trace elements support healthy growth, strong roots, and improved yields in apples, citrus, and stone fruits. Rapid absorption makes it ideal for foliar or soil application, helping Australian growers achieve vibrant, productive trees throughout the season.
When should I use a potassium-rich fertiliser for the best results in flowering and fruiting and at what rate?
For optimal results, apply a potassium-rich fertiliser like Kendon High K during periods of rapid growth, flowering, fruit set, or when plants are under stress from unfavourable weather. This ensures your plants have access to readily available potassium when they need it most, supporting healthy blooms and abundant harvests.

Are there any compatibility issues when mixing this fertiliser with other agricultural chemicals?
Kendon High K mixes well with most insecticides and fungicides, but should not be combined with alkaline products such as Lime Sulphur, White Oil, or Bordeaux, as these may cause precipitation or reduce effectiveness. Always check compatibility and follow label instructions for best results.
How can I supplement magnesium when using a liquid fruit or vegetable fertiliser?
If your plants show signs of magnesium deficiency, you can add 25g of magnesium sulphate (Epsom salts) per 100L of diluted Kendon High K solution immediately before use. Do not add magnesium sulphate to concentrated High K, as this can cause precipitation.

Testimonials
We have won another gold medal for our Shiraz, all due to Kendon High K allowing my vines to achieve their full genetic potential. And we can pick our grapes 2-4 weeks earlier than our neighbours when the fruit has already achieved 22% Brix.
One day after we fertigated my apple trees with Kendon High K, the apple leaves were noticeably greener and shinier. We could all see the difference. With our apricots, the fruit were on fire, they were so red! The fruit ripened all at the same time, meaning 2 picks instead of 3. The skin was firmer and the flesh was the sweetest we have noticed. This is due to our use of Kendon High K fertigated 3 times before harvest, 2 weeks apart. True confession: this season, we missed our window of applying Kendon High K to the apricots pre-harvest. The crop was pale, didnt ripen evenly and fruit was not as sweet as last season. Having seen the difference in the results, there is no way we will miss applying Kendon High K to our fruiting crops.
Kendon asked why I didnt buy insecticides and fungicides for my potato crop. I told them, I dont need to! I have been using Kendon High K for the last 25 or more years. I watch the deliveries of insecticides every 2 weeks to my neighbours and am thankful I do not have those costs.
