Len, I have a walnut tree and all know is they do not like any root disturbance. Oaks do no like to be shifted either, we grew oaks in pots from seeds and transplanted, they just did not thrive. I think it is because they send out a long taproot first and if this is restricted or unset in anyway they just do not grow. I would plant straight in the garden. I have an oak that is still under a foot tall after 5 years from a pot. Both my walnuts are grafted nursey bought and they are okay, one is actually "fruiting"

The walnut is the walnut seed - to state the obvious. Tennisball sized and shaped it is not - it is walnut sized and shaped.
I don't think, even in fruit, they approach tennis ball size, but correct me if I am wrong. If they are still in fruit - the seed is not mature enough to plant - it needs to remain on the tree until the fruit dries and cracks.

I do think it would be a lot less frustrating to buy a grafted walnut tree, which will still take ages to reach fruiting stage, and you know that what you get will be edible.

Someone tossed almonds into my garden and one of them rooted and I now have a tiny plant sprouting from the almond nut. As it was in my rose bed and right near my house I lifted it out of the soil and plopped it into a shot glass filled with water and soil. (That's how tiny it is)

I don't want to throw it away as a weed as it reminds me of the apple sapling that started because my sister threw her core in the garden and not in the bin. Mum and Dad dug it up and threw it away. (this was all years ago, but fond memories die hard)

Does anyone know if I plant it out whether or not it will grow?

I don't mean to plant it in my garden, but I know my partners parents have the space for it.

Cheers

I have had good luck growing walnut trees and transplanting. One tree, sprouted from seed in Illinois was transplanted in Arkansas when it was about 18 inches tall. The tree was again transplanted a year later in Arkansas. After two more years, the tree was moved to Georgia and replanted, finally after another year, the tree was replanted in its permanent location. Now 25 years old, the tree is producing nuts and is about 40 feet tall.

I was thinking of planting a Walnut tree when I lived down south and I knew they took around ten years to fruit so I gave it a miss.

But 25 years goodness I would be pushing up daisies by then.

They have a large root system so I am amazed that you managed to transplant them so many times..

I agree, that tennis-sized what is it, sounds not to be a walnut seed.
But you know how these Ausies are with their tennis....maybe someone was just dreaming of the next Australian Open.

Anyway.....to root a black walnut:
ÂÂ
Black walnut seed..... Â.throw in plastic bag Â.surround in peat moss. Keep soil active with compost which you dampen
then leave overnight on counter; then into freezer for 6 weeks.
Peel outer hull off, wear glovesÂÂtake whatÂs left and put into a soak in warm water overnight; then pot it up in depth which relates to the size of the seed... (about an inch) in potting soil.
May germinate in 6 weeksÂ..if notÂ.take look...Âif hull has not opened, put whole thing in freezer again for 6 weeks in plastic bagÂ
2nd time in freezer if necessary you can put the whole pot in.

Now this method of mine is related to what would be done here in Ontario....I'm guessing the same end result can occur if put into a freezer in Australia.
Cold is cold....anywhere you meet up with it.
And right now darn it.....its too darn cold here....and just last week it was near 80F. (26C)

How long would it take to harvest the tree itself for the timber?

between 50 - 70 years for timber harvest i beleive.
