Guava can be propagated by seed, branch cutting, grafting and air layering.
For commercial cultivation, it is best grafted onto a established root-stock.
The guava seedlings grow very fast if proper care is taken
Successful Guava cultivation is grown under tropical and sub-tropical climate.
In areas with distinct winter season, the yield tends to increase and quality improves.
High temperature at the time of fruit development can cause fruit drop.
Guavas can be planted at any time of the year, but the warmer months are better.
Plant them 2 to 3 metres from other trees and 5 metres from other guava trees.
Dig a hole about twice the size of the bag in which the young tree is growing.
Remove the soil from the hole and add some compost and manure.
Guava is mostly grown under rain fed condition.
During winter season, irrigation is provided at an interval of 20-25 days
During summer months it is provided at an interval of 10-15 days by the ring method.
Drip irrigation has proved to be very beneficial for guava.
About 60% of the water used for irrigation is saved.
Besides substantial increase in size and number of fruits is observed.
Guavas prefer regular deep root watering, allow the soil to dry out somewhat between waterings.
Provide regular water during the growing season, and reduce watering during the winter.
Apply water at the base of the tree, avoiding its foliage getting wet to prevent fungal disease.
The older branches of the guava tree produce larger size guava fruit.
So to promote branch growth, the tree must receive regular water
Guava tree is heavy feeder, so it should be fertilized every 1-2 months when it is young; thereafter 3-4 times a year
Time of fertilizer application depends on the region and crop variety.
In first week of July for winter season crop.
The plants are manured twice a year, first during June-July and second by during October.
In case of older plants the fertilizers may be broadcasted over a radius of 120cm from the base and forked in lightly without damaging the roots.
A fertilizer high in potassium is the best fertilizer for guava trees to increase fruit production.
I feed my guava plant with a liquid fertilizer throughout the growing season.
Always water your guava plant after fertilizing to minimize the risk of burns
The guava tree blooms in early spring, but may bloom all year in mild climates.
Guava tree has perfect flowers with male and female parts in each flower.
Honeybees pollinate the guava flowers.
If there are no bees in your area, then you may hand pollinate the flowers.
Use a very small paint brush and tickle the inside of flowers.
Spray your guava tree a 5 % solution of urea mixed with a wetting agent just before flowering.
When the urea spray dries, then water the plant.
This will increase the duration of fruit production.
