Farmer Bhikhabhai Sonabhai of Gujarat gives protection to such trees. In early May, he first digs out all soil immediately around the tree till the roots are exposed. He then mixes 1 kg each of "aankol" (Alangium salvifolium) fruit rinds and stem bark of mahua (Madhuca indica) fascicles and spreads the mixture on all the sides. Initially, he spades in the soil again to cover the exposed roots. It has been the experience of Bhikhabhai that the tree so treated bears good and quality fruits. "Aankol" (Alangium salvifolium) is a 3 to10 metre tall, thorny tree having ash coloured bark and bearing green lanceolate leaves. Mahua (Madhuca indica) is a 10 to15 metre tall tree. It blossoms and sheds the flowers in March and develops fruit-bearing ascicles in April/ May, known as "dodi" in the Dahod area.

"Early flowering and fruiting in mango tree – A quarter to one feet pieces of alangium (Alangium salvifolium) and organic manure are layered on each other for three to four times in trench and compost is ready after 8 months of buried. This compost is layered, around the trunk of mango (Mangifera indica) tree. It will induce early flowering and fruiting in mango tree. This is a traditional practice learnt from forefathers."
