Eucalyptus High K – Soluble Tree Fertiliser

Professional grade soluble plant fertiliser with the ideal nutrient make up for Eucalyptus trees. Essential for happy container-grown Eucs in patio pots and also great for giving a boost to Eucs grown in the ground.

The special formulation allows the full range of nutrients to be available to the plant even in areas with hard water. Hard water can be problematic as it has a tendency to make iron and other trace elements, vital for correct plant metabolism, less accessible by ‘locking them up’ in insoluble compounds.

Eucalyptus High K is as safe and easy to use and store as any other soluble plant fertiliser.

At Hardy Eucalyptus, we have been using Eucalyptus High K in the nursery by the tonne and are very pleased with the results.

Why use this product as opposed to other readily available plant fertilisers?

Eucalyptus High K has the specific,  correct formulation to keep Eucalyptus happy.   Not too much Nitrogen, very low in Phosphorus, high in sensible Potassium.

The formulation: 13:10:28+2MgO+TE where the 13:10:28 refers to N:P:K: ratio.  2MgO is the level of Magnesium and  TE stands for trace element.

Nitrogen ( N:13) is for shoots and leaves.  Eucs love nitrogen, but like me and chocolate – we should only be allowed to consume it in small quantities.   Nitrogen is like crack cocaine to a Eucalyptus. Over do the Nitrogen with a Euc and it becomes sick and falls over – literally.  Nitrogen results in fast and furious growth, which is unsupported and sappy.  The tree has no means of supporting this summer season growth until November (due to its complex biology) and so it falls over.  This sappy growth also compromises winter hardiness, leaving your tree at risk of extreme frost damage.  Eucalyptus only require a small amount of nitrogen to be happy.

Phosphorus (P:10) is for roots: Australia is a land of impoverished soils with very little phosphorus, so Eucs dont really know what to do with it!  Put it this way, they are reputedly not keen on it.

High potassium (K*)  (K:28) is traditionally known for flowers and fruits, but it also has many other functions to perform with in a plant. It is the first aid kit; in that it helps the plant to fight off diseases. Potassium also regulates osmosis (water-flow) throughout the plant; this is important under drought conditions where plants can suffer drought-stress.  Furthermore, and especially in Eucalyptus, Potassium helps the tree ripen its tissues in readiness for winter. It is like a frost-proofer.

*K from the Latin Kalium – derived from the Arabic word al-qalyah (alkali), meaning plant ashes.  In English, potash was manufactured from ashes in pots.

Magnesium is important as it is the at the centre of the Chlorophyll molecule – the green stuff in plants that converts sunlight into chemical energy,  which in turn, helps to build plant material, amongst other things.

High K contains a good range of trace elements TE (think plant equivalent of vitamins) in a slow release format – see the next tab for a full list, but these elements such as Boron, Molybdenum etc. all have specific jobs to carry out with in a plant to keep it healthy and functioning correctly.

Packaging is completely compostable, including the ziplock. Please put it in your compost heap or green waste bin after use. Composition: “Eco Kraft paper”, bio-cellulose film, starch zip.

Eucalyptus High K is a multi-purpose product; you can use this plant food in Spring & Summer to feed your roses, Japanese maples, flowering and fruiting trees and shrubs, and even on lawns in the Autumn.  Hardy Eucalyptus have successfully used Eucalyptus High K to feed a range of potted plants including Lemon trees, House plants, potted fruit trees and a range of perennials, with great results
