Avocados like plenty of light and plenty of warmth.
Keep an eye on the leaves because they give a good indication of when watering is needed.

Water slowly and thoroughly.

Drainage needs to be good.


Compost - multipurpose is adequate.

Feed the plant regularly during the summer months with a general purpose feed it should thrive quite happily.

The avocado bears both male and female flowers although these tend to open at different times of the day. If there are insects in the conservatory you will very likely find that pollination has occurred and fruits will develop.
So fruit bairing in greenhouses/conservatories you need to collect pollen from the male flowers with an artists paintbrush and help along the pollination when the female flowers open to increase fruit bearing
