Prune or not to prune Jackfruit Sapling

[Z070305]

Hi everyone, I just planted the jackfruit into this big pot. Reason for not planting it into the ground directly- the soil layer is not deep enough. I tried digging a hole and was o steucted by a layer of cement about 12 inches from the top layer.

Question: Should I prune the sapling to promote geowth of leader branch and restrict its overall height?

I have pruned the two mango saplings as below. Not sure if I have done it correctly.

Jackfruit tree is too small, I think i heard R. Cambell say cut at 9’

Indeed too small, i would keep it in pot until 4-5 ft tall. No need to prune anything  now, it needs those leaves to photosynthesize and grow since it doesn't have too many to begin with.
You also must break all that cement at least 3ft wide when ready, hopefully its not too thick of a rock layer and you hit dirt down under again

I imagine electric jackhammers are available in Singapore. If roots get below the concrete there may be little competition down there.

My thought exactly. I believe UFL recommends keeping them 10 - 15 feet in height.

I just topped my 7 years old Gold Nugget's leader trunk at 15ft, still waiting for fruit though
And remember that Jackfruit likes to be pruned only in the rainy season, as per Dr. Campbell
