Trees have Tap Roots that access subsoil moisture. When planting a tree you accelerate its establishment by providing its tap root with ease of access to subsoil moisture. READ BELOW for LOW COST RECIPE to Fast Track Tap Root Establishment. THE OBJECTIVE is to create 10% air pockets in a tree hole plug that provides nutrients for the seedling. Hoop Pine Bark from Bunnings is ideal for trees like Silky Oak. So have a go, wait, watch and learn. Some trees like a bit of added charcoal – some don’t. The safe bet is wood shavings sold as animal bedding at Rural Produce Shops.

 SOMETHING GOOD TO KNOW: If you have fertile soil + enough rainfall/water to establish seedlings – sometimes all you need do is dig a tree hole. Recent plantings of Tipuana on Black Soil Country were planted into a 1.8 metre deep tree hole made with an auger on a tractor. No nutrient was added – it was the disturbed loosened soil profile that granted access to the tap roots of the Tipuana Seedlings that grew 2 metres first 9 months before frost. DO SOME LOCAL RESEARCH Recommended. AVOID EXCESS NITRATES. BEWARE of FROST. Watch OUT for TREE EATERS . Maintain WATER + MOIST TREE HOLE. Protect Trees from Wind/Sun.       

THINK LATERAL trees need food and water. You select what they eat. What trees eat as seedlings then determines how they will get a start on in life. Humus is living soluble plant food made from carbon and nitrogen from things that were once living.

Too much nitrogen is potentially adverse as trees are more susceptible to frost and heat and insects. Excess carbon locks up nitrogen and minerals. If you were to use only leaves from Saltbush as a tree hole backfill you would be mostly spot on. Twigs and leaves from Casuarinas will work well as will most cellulose rich plant matter. Or buy in wood chips/shavings from your Rural Produce Shop/Bunnings.               

carob tree

PHOTO 1: Carob Tree (grown from seed) was planted when 300mm tall in January 2023. By May it was 700mm tall. First “black frost of May” has defoliated this Carob Seedling. Excess nutrient from nitrogen is the cause. Hardier established carob trees withstand minus 4 frost here with damage only to flowers (when in flower). 

PLANTING METHOD: Tree hole dug narrow to 600 mm. Backfilled with a BLEND of (1) 80% Wood shavings (2) 15% Sheep manure (3) 5% Fine ground charcoal. NOTE This one Recipe of Many. Use whatever is viable and available.


MIX this Blend into soil at about 20% with 80% Soil  

OPTION to ADD BLOOD + BONE. ADVANCE TREE HOLE PREPARATION provides for nutrients to breakdown reducing risk of excess nitrates.  OR increase cellulose and reduce protein to find the right balance. SOME TREES will thrive on this blend without any frost issues – others will not.

FUNDAMENTAL is to create a Porous Tree Hole Plug to encourage “Tap Root Development” USE OTHER MEDIUMS eg: Wood Chips + Bone + Twigs + Leaves etc..  

EVERYTHING is competing for water, so spacing of trees is important in lower rainfall zones. So some companion plants may be detrimental when it goes dry. Old Man Saltbush is a potential adverse companion. On the other hand Saltbush is able to be prune back to ground level. Belah is a prefered companion tree that can provide shade. It also imports water and nutrients from up to 15 metres away from its base. RECOMMEND READING: Drought Buster Trees and Fungus   

tree planting method

PHOTO 2: Black Stump of 6 year old Leucaena may have tap roots now to 5 metres deep. Now we can plant any selected seedling next to black stump. New seedling will be able to penetrate subsoil by following roots of dead Leucaena as they break down in soil. Leucaena is planted also on same day with some new tree seedlings. Its growth is then managed with pruning or grazing. THIS Stump is also seen as a whipstick tree PHOTO 4 Leucaena Seeds for Sale prior to being burnt off.

PHOTO 3: Leucaena Clump planted from 10 seeds now 3 months old. You can prune this clump with secateurs or let it grow and frost will knock it in some locations. Sheep and cattle will also prune it for you. Leucaena will grow to 4 metres within 5 years. SO Keep It Short OR Let it Grow. Eventually you may want to kill it off. If you prune it enough it will never get out of control.

apple from seed

PHOTO 5: Apple grown from seed was planted into an Old Clump of Leucaena on heavy black soil. No other amendment was made for apple planting + result is 700 mm growth during first growing season with minimal water applied. Apples grown from seed will send up multiple trunks. You decide to let them grow or select the strongest shoot as main trunk. Old Clump of Leucaena was 10 years old. So you can plant clumps many years in advance or on the same day as planting your fruit tree.
