We have two citrus trees - Meyer Lemon & Kaffir Lime, that we put in big pots, so we can bring them in the house in Winter, as they don't tolerate freezing temps.
Summer before last, the fire ants made a nest in the lemon pot, and almost killed it.
We took it out of the pot and pressure washed the roots to get rid of the ants. There weren't a lot of leaves left, so I pruned the branches aggressively, to channel all the energy to growing the roots.
Last summer, we didn't get any lemons, & it took a while for the leaves to start growing. Eventually the leaves did fill back in. But not nearly as much as the lime tree, which was about three times bigger.
During the Summer, DH gave the citrus trees monthly feedings of Azomite, and watered them with waste water from the duck ponds. The lime tree got some blossoms, but not a lot. We are now picking them as needed.
The lemon tree never got blossoms, but I figured it was because it was recovering frI'm it's near death experience the Summer before.
When we brought the trees in before the 1st frost, I pruned quite a bit off the lime tree, so we could get it through the front door. I left the lemon tree unpruned. I also gave both trees a feeding of fish emulsion fertilizer mixed with kelp, for added minerals. We then munched it with hay, to keep them from drying out.
Here is a Kaffir Lime
And a Lime blossom cluster
About 2 or 3 weeks after I fertilized the trees, they started getting blossoms, LOTS of blossoms!!!
This morning 2 of them finally bloomed this morning
