Yellow leaves on Guava Tree

    6 responses

Lizz starts with ...
The leaves on my guava tree are turning yellow and falling off. I have no idea what could have caused this sudden change other than maybe it is being overwatered.

I would appreciate it if you could throw some light on the situation for me.

hi Lizz,

my pink supreme guava lost quite a few leaves after it finished fruiting in August. I think it was a combination of extreme heat, winds, and leaf drop in preparation for new shoots. it was actually looking a little bare in places - but it's starting to fill out with new growth now. over-watering in spring after an extended winter dry spell has also caused me the occasional problem with leaf drop such as you've got.

Hi Kate, the problem continues. I have another guava tree close by. It is doing well and is even fruiting.

Thanks for your advice. Do you think I should just wait and see?

Cheers

hi Lizz,

is that a pic of the tree having problems with yellowing leaves? if so - I see quite a bit of new growth, so I'd look closer at the branches with the yellow leaves to see if there is new growth starting push out where the leaf is dying. I tend to be a wait and see type of gardener - take care of the basics such as checking of bugs, making sure water and drainage is ok, feeding/mulching, and looking for signs of normal new growth behavior. if something is putting out healthy new growth and has yellowing/dying older leaves - then I figure those leaves have passed their use-by date. if it has lots of new growth which is looking a bit malformed and dis-coloured I check for bugs and give things a light feed with an organic fertilizer and look for improvement. it's not a fool-proof approach - but it seems to work most of the time, and saves me from becoming too obsessive.

The guavas can easily lose leaves for any reason and they usually put the growth on shortly after. It usually happens in winter conditions. The guave trees are variable so it is not unusual for one to look different to another at this time. There is a chance a disease caused it but without seeing it I dont know and time will tell if it releafs or dies.

This is my other tree growing 2 meters away in the same raised garden bed.

The other tree is still losing leaves. I took a quick look from an upstairs window this morning. I will have a closer look when I get home from work.

hi Lizz,

going by the original pics you posted - the tree did have lots of healthy new growth shooting up, and the yellowing leaves were confined to older leaves located towards the core of the tree. that tends to indicate a normal cycle of shedding the old and growing the new. those old leaves do have to be shed eventually, to make way for new branch growth or to simply allow for the trunk and branches to have those bare sections of bark in the shaded center.

the key things I'd look for are healthy new growth, no signs of insect infestations on the yellowing leaves, new buds starting to form where the yellowing leaves attach to the branch, and age of leaves.

can you post some updated images of an overall tree shot which takes in some of those yellowing leaves?
