Yellowing leaves on newly planted Ginkgo Biloba

Planted a Ginkgo Biloba tree in March.  Have been watering it well with lots of good drenching especially with the really hot weather last week but have noticed that there is a definite tinge of yellow to a number of the leaves.  I understand that this is due to lack of water at roots.  I've upped the watering, but want to understand if this will reverse any adverse impacts or is it only going to get worse?

The tree itself was a present and wasn't cheap, so would be upset if its going to die.

Is there anything I can do to help it along, such as a foliar feed?  When I planted I followed the tree nursery advice to the letter of putting mycorrhizal fungi in the bottom of the planting hole, using tree and shrub compost around the sides, and making sure I planted at the same depth it was in the pot it came in.  I have noticed when watering that some finer roots are coming to the surface but just think this is from all the watering washing some of the top soil from the pot aside, so I have placed a thin layer of general purpose compost just to stop them being exposed.  My soil is sandy loam and does drain fairly freely.   TIA for any advice/help.

    It is far too early in the year for the natural yellowing of the leaves in the Autumn .
    Gingko biloba is prone to chlorosis , especially if your soil is slightly alkaline ; try treating it with a good dose of Sequestrene or something similar .
    This will replenish any deficit in vital minerals or trace elements your tree needs .

    Thanks - I have some seaweed extract which I've read can help with chlorosis.  Should I use that when watering?

    Sounds like a good idea ; might also be another good idea (without damaging the roots), to incorporate some ericaceous soil around your tree .This might help to retain more moisture .
    If you live in a hard-water region , this may have a detrimental effect also ; can you access rainwater if possible ?

    I prefer using rain water from the water butts, but had to resort to tap water when they ran dry.  And yes, the water is hard.  Following the rain last week after the heatwave, water butts are full again, so have resorted to them.  Thanks for the advice - will add the seaweed extract to the watering.

    Good news regarding your rainwater supply !
    Hope your tree survives ; they're pretty much free of pests and diseases so don't foresee any major problems .
    Good luck !
