Flower buds are dropping from my magnolia.

The magnolia tree I have inherited by purchasing a house is enormous and constantly covered in healthy leaves but the many buds it produces all fall off. It gets morning and afternoon sun.

Flowers and Ornamentals • Diseases

You may check the following aspects which may cause the stress of the tree: 
- Soil drainage, plant wilting after heavy rain due to lack of air in the soil. Best to improve soil structure by digging in garden compost and Dynamic lifter into the soil. 
- Root damage, may be caused by either pests or disease: 
    - Pest is generally soil born larvae of beetles such as curl grubs feeding on the roots. To control, soil drenching with eco neem to eradicate the grubs in soil.  
    - Disease such as root rot or collar rot could cause diebacks in sections. For early infestation, prune off any diebacks and spray the whole plant with 'Yates Anti Rot'. It is a systemic fungicide 
      which is absorbed by the foliage and travels down to the roots, can be used on various plants to control phytophthora root rot, crown rot and collar rot. Click here for more info on this
