Need a little help,
for the past several years, I have been trying to grow
several Dwarf Citrus tree. They do fine outside, but
when I bring them in for the winter, most of the time
they will not make it to the following summer.. I have
a severe problem with leaf-drop. Eventually the plants
die. I live in Northern Illinois, so leaving them out
side to over winter is not an option. Trees are watered
when the soil gets dry. fertilized every other month,
humidity in the house is around 50% or so, plants are
in a sun porch that stays at around 70 - 74 degrees day
and night. The plants get some direct sun, but mostly indirect.
Keeping them alive and even eventually fruiting has become a challenge. Could itbe that they (oranges, lemons, limes) are not getting
enough light? If so, what would be better LPS or MV
additional lighting? If so, what wattage??
