Why does my mango tree have signs of yellow leaves are the grass cuttings around the base causing this

I have just moved into a house that has a big mango tree in the front yard and it looks sick compared to others around. The previous tenant has put all the grass cutting round it, right up to the trunk, I am going to clear them away but what else should I do to get it better. Thank you.

Dear Judith,

Certainly you should remove those grass clippings around the base of the mango tree. Grass clipping should be allowed to rot down and then added to a compost heap for at least 3 months before applying as a mulch. Adding uncomposted grass clippings directly to the soil can cause nitrogen drawdown and yellowing of the leaves. Composted mulch can be added around a fruit trees but it is never placed right up around the trunk of the tree. By leaving the mulch close to the trunk the bark can become wet and soggy making it a perfect entry for insect attack and fungal disease. After removing the grass clippings, you can then improve the health of the tree by giving it regular applications of seaweed extract. This will act as a tonic and help the tree to recover. When you see signs of the tree improving, then you can apply a fertiliser. Try Yates Thrive Natural Citrus & Fruit Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your fruiting plants the right balance of nutrients for their growing needs.
