Some of the leaves on my Kumquat tree are slowly going brown and drying out. the tree is 2 or 3 years old, is planted directly into the lawn in full sun and we live in the South West of England. The tree has never flowered but I live in hope! Is there something I can feed it to bring it back to full health? regards polly.

This could be a watering issue. Either too much or too little.
You should water your Kumquat deeply once a week during it's growing period.
Kumquat do not like soggy roots and need a well draining soil.
If it has rained, no watering is likely needed.
Also make sure you mulch with a hardwood mulch, but keep the mulch back 6 inches from the trunk of the tree.
Review the links below and check the nutrient and feeding requirements. Another area that may need attention.
