More sun the better--direct, unobstructed sun will help. Outdoor sun is best--many hours of it!. It's normal for some of the flowers and developing fruits to abort and fall off but obviously, there is something not to their liking here--maybe dry interior air. Try to find a sheltered exterior site for them if possible. Go easy on watering and feeding until you see growth. Citrus tend to grow and fruit in spurts. They'll do nothing for months then suddenly sprout new leaves and/or enter a fruiting cycle. Regarding flowering cycles, my oranges, Eureka lemons, and kumquats will bloom in the Spring (earliest, in February) and April is peak (in the Northern Hemisphere obviously). Mine are literally covered in blooms at this time. Fruits seem to spend the rest of the summer maturing and growing but coloring seems to develop over the winter months. Meyer's lemon seems less seasonal and will bloom and fruit throughout the year. Limes too (being VERY tropical) are less seasonal, and given adequate sun and heat, will fruit and flower throughout the year. At least, that's been my experience with Citrus at a non-tropical latitude. Also, Citus and their kumquat relatives thrive on a bit of 'though love'. If you have been watering consistently and keeping them slightly moist, ease up on the water--let them get much drier between watering. Once you see an increase in either green growth or blooming, you can increase watering. Good luck!

I'm not sure if I should have started a new post, but my question is similar to this previous post so I added to it. I bought a house in a coastal county in Texas. There are 2 stocky citrus trees. I thought they were lemon trees. Over late summer ( I think it was) what looked like limes began to show up. A worker told me they were limes, then gave a dissertation on why they were limes not lemons: leaves, thorns, etc. I waited, but the skin didn't look ripe. Soon they got so big, I thought they were just big limes. I picked so many and gave them away....they aren't limes :-) The fruit on both looked like lemon, so several weeks ago I began picking the lemons. But the lemons are so different on the same tree. Maybe I left some on the tree too long? On one of the trees, a lemon may be twice the size of another lemon, or one may have a smooth thin skin while another has a very thick skin, and some are very orange in color and others very yellow. Now on the second tree, fruits looks like lemon on the more shaded side, but the full sun side looks like oranges for sure - they are big, round, thick rugged skinned, orange colored, they peel like oranges, are orange on the inside, but tastes just like a lemon. I'm so confused. Do oranges have a very sour taste before they are ripe? This house was built in the 1940's, and both trees, which are about 10 feet apart, are very thick with several trunks at the base. It's possible that different varieties were planted inches apart from each other I suppose. I'm guessing they were planted a long time ago because one is planted so close to a pear tree that it almost encloses around the pear tree, as if they didn't think about long term spacing; so I've pruned back quite a bit; actually both needed serious pruning, they limbs were dragging the ground every where. I'm clueless when it comes to these trees. Any suggestions would be helpful. Thanks. -Nancy

I am near montreal so I think it is zone 5a or 5b No choice to winter it inside since temps go down to -35 celcius when I bought the tree spring 2015 it was tagged as a meyer lemon but I am not convinced it is really one. I bought some meyer lemon at the grocery store to compare the ones I harvested and mine were much bigger and more tart to what I remember.. Also i always thought that the leaves on my tree were much bigger and of different shape than the ones i see in pictures or that i have seen on other meyer lemon trees... the mix in this one is mostly the mix it came with from the nursery containing a lot of perlite mixed with a bit of mix I used to prepare for my cacti ( mostly sand small gravel and a little earth from my garden) for my lime tree i made a mix of pre mixed cacti and succulents mix with added sand , bark and coarse perlite

That tree is 10 years old; it is naturally a shorter and bushier type, assisted by a little pruning. That tree produces 400 lemons per year; that and the natural shape of the tree is why I selected that cultivar to be the future of Meyer lemons in Guatemala. To date all of the 35,000 trees we have produced have been genetically identical, having come from a single tree selected as the best of the first 500 I brought from California. I have made a decision that this new cultivar is better than the previous "Mother tree" because of the consistent production and the shorter/broader size, Let's hope that I am right; only the future will tell. We have a new "grove" of 64 of this tree, which beginning next year will be the budwood for all our new production. We may have to adjust our spacing a bit with the broader tree; we will experiment with that before recommending spacing for new growers or expanding growers.
