We've got some citrus trees Herself's mother gifted us when we got the Big House. So... 13 years now. This year is the first time we got fruit, from the 3 survivors of the 6 originals...

Turn off water and drain any automatic water points (pressure valves for sippin'), bypass float valves for trickle on tanks or drain the hoses that supply them.
