Why use the Smart Fertiliser and Alg-A-Mic Seaweed Dream Team?

Hardy Eucalyptus’s CEO, Hilary Collins  has a background in horticultural research, including the cultivation of tree crops. Hilary runs ongoing research and development trials at the Nursery, using her understanding of complex plant biochemistry, which led to her sourcing Smart Fertiliser for Eucalyptus plants.

It’s really clever stuff.  Smart Fertiliser is a specialist slow release plant food, perfectly balanced to encourage healthy ‘top growth’ on your Eucalyptus tree and uniquely available to keen gardeners through Hardy-Eucalyptus.com.   Its slow release action shuts down in very cold and very hot conditions, but achieves maximum release under optimum growing conditions. This means the fertiliser is present for your Euc when it needs it most and unlike many fertilisers, it does not leach unnecessarily into the environment under cold, wet conditions, causing pollution.

Smart Fertiliser is of particular importance if you are growing for cut foliage, screening trees/hedges, firewood logs or when establishing liners or 1 litre stock, especially in a field situation.  Standard specimen Eucalypts don’t require feeding once established, but if you are harvesting a crop or regularly pruning a feature tree, both actions of which remove stored collateral*, then your trees require plant food.  Frequent removal of vegetation without feeding will lead to Euc-exhaustion!

*Stored collateral in a plant means the woody stuff, where the plant has laid down woody fibre which contains carbon. When you prune a plant and remove that live material, you are effectively making a withdrawal from its plant ‘bank account’.  Make this withdrawal on a regular basis without putting back plant food in some form and you run the risk of exhausting and killing your plant 🙁

And it’s a ‘team effort’.  Smart Fertiliser works in combination with the contents of the Alg-a-Mic seaweed Fertiliser and also your plant’s mycorrhizal fungi to provide sustained nutrition during the growing season, in the correct proportions to encourage healthy plant growth. (See Timing Application below)

Smart Fertiliser is a multi-purpose product; you can also use this plant food in Spring to feed your roses, Japanese maples, flowering trees and shrubs, and even on lawns in the Autumn.  Hardy Eucalyptus have successfully used Smart Fertiliser in a flower cutting garden with great results.

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.
