My ponderosa lemon tree has lost about 70% of its leaves. Blooms seem to come out of a few places. Will the leaves grow back in the summer by themselves or should I prune?Starting to worry about it losing all of the leaves. I've put it under the grow light as of today. :acorn:

With your loooooong winters, I feel your concern.

At my house, citrus dropping leaves is no concern.
They leaf out with the warmer temps.

Whether you prune or not is probably a personal choice...
How much room do you have at your house for a large citrus?

At my house, with citrus that I grew from pips.... I useta root prune in the autumn when I dug them out of the ground and potted....
And.... Pruned the top growth in the spring... Think bonsai.

My citrus always tolerated a lot of abuse.... Any more.... I'm more focused on citrus that is hardy to my garden.... A lot less room at my house to be bringing this stuff inside....

Kevin - I now have two Meyer lemon trees in pots. They're outside in the warmer months and inside once the weather starts getting colder. I used to agonize over every dropped leaf over winter, wondering what I've done wrong. Most of the winter, I only get maybe 25% of available sunlight, even in my little heated greenhouse. Supplemental light helps a little but I still lose leaves. Right now, both plants are starting to get new leaves. They've both bloomed while indoors and one of the trees is getting ready to bloom again. The best I can do is to keep them healthy with regular watering (I try to use rain water or distilled water) and fertilizer. Sometimes they get a dose of chelated iron or fish emulsion. I do spray them a couple of times over the winter with Azamax to control spider mites which are a problem here during winter. Your tree will leaf out as we get more sun.

I had it in front of a large south facing window but we only get a few hours of daylight daily. It's now in a corner in the basement with a 28W grow light on it. I sprayed It with a mix of very diluted dish soap in water to kill spider mites. Maybe that made it worse

Whatever you can do to maximize the light will be beneficial. Can you move your tree and light setup back to the south-facing window? You'd then have two sources of marginal light for it. Do make sure you spray the leaves with clean water an hour after using the soap solution.
