Sandy,
when I weed, I cut down to the area around the root, where no sprouting can come from.
This leaves the soil undisturbed and roots to rot back in, with nutrients and food for microbes.
Sort of lazy man's composting.
Sometimes you can use the weeds to help a tree water wise, they provide a buffer when the
tree has been heavily pruned and can no longer drink as much it could before.
Watering wise, some trees down here spring back faster after repotting than others, so one
has to be careful and water by observation.
Additionally some need more water than others and we mix up the tree /shrub types to
confuse and deter insects etc.
Mono cropping is really bad, encourages insects and diseases.
We don't need to spray for anything.
Just feed the leaf cutter ants a batch of treated citrus peels, and the queen is gone.
Now crossing over to companion planting in bonsai pots to see if we can protect the
Fukien teas and Serissa s. Ants love Fukien tea, and leaf cutters shred Serissas.
Did note a small growing piece of small of leaf seasonings stop the leaf cutting.
Since Basil protects tomatoes, basil leaf powder might as do the same ?
Let you know how it goes.
The ants do not like the metal stands, so the Fukien teas stay on those, but it would
be nicer to have them on the concrete stands on the eastern facing patio.
Good Day
Anthony
