Not too worried but just more curious as to why my 3 year old dwarf lime will not flower. It looks healthy and it gets the same light, watering, and fertilizing as my smaller already fruiting meyer lemon which you may be able to see in the photo. Any answers/suggestions? Also does anybody have a suggestion as to how to heat a greenhouse in a garage? That is my best option for a place to put tropicals in the winter if possible otherwise they can go in a basement but will have little room. Thank you!!
