My lemon tree has a few leaves appearing to be shriveled. What could be the cause? We live in the Houston area.
While a few shriveled leaves may not be cause for alarm, here is an article that will inform you of possible causes:

Tree kept indoors during cold months and in full sun on deck during warm weather. Tree looks very healthy and free of insects. Blossoms everywhere but they drop before forming fruit.
How old is your lime tree? Lime trees need to be at least 3-4 years old before they are mature enough to bear fruit.
When it blooms, is it indoors? When they bloom indoors, they can suffer from blossom drop because no pollinators (bees) have access.
Here is an article on the reasons for lime blossom drop that may be helpful:

Can I plant a lemon tree in the same bed as roses? Full sun, plenty of water. Small garden so roses will be quite close to the lemon tree.
I really would not recommend it. Rosebushes do not like to compete with trees for water and nutrition. If the garden was large and there was a good 6 feet from the rosebushes, then may be okay. But for small gardens I recommend finding a nice spot near the rose bed yet 6 to 8 feet of clearance.
I have two nursery-grown lemon trees planted in an open, sunny area SW of the house in central Texas. Each produced over 100 lemons the first year, fewer the second, and have set virtually none the third. We keep them bushed for ease of maintenance, and covered, with heat lamps, during freezing weather. We have had a lot of rain and numerous overcast days this year, but few the last couple of years. One tree puts on rapid new growth, while five feet away the other is much slower. Our soil is rich, dark, deep, and well-drained. Any suggestions would be helpful. These are very lush plants, so should we prune? And if so, when?
I have listed a couple of links to help you.
I do think weather conditions may be your most likely issue, but familiarize yourself again with the watering and fertilizing requirements.
Also the pruning instructions in the article below.
With a little tlc I think you can get your lemon trees producing again.

Most likely caused from a scale bug infestation.
Neem oil is good treatment but you can make a insecticidal soup also.
You may want to check all your plants and quarantine your Lemon Tree.

I started a lemon tree from a seed and it is about 20 inches in height. I just noticed thorns growing on it. Why is it growing thorns?
Here is an article that will explain this thorny phenomenon:

I planted a lemon tree a few years ago and am getting some large lemons. However, the pith is really thick and the fruit area is pretty small. Any way to correct that?
