    Lemons and other citrus plants actually bloom when they are under mild stress, so typically blooming occurs during the cooler months. That being said, it is not uncommon to also see a citrus tree bloom during drought or when affected by disease or pest.

    When a lemon tree is in bloom, it is a good idea to fertilize lightly and increase water to the plant. If your tree is isolated (i.e. does not have access to pollinators) you will also want to use a paintbrush to gently "paint" the inside of some (but not all) of the blossoms. This will help to ensure fruit. You do not want to pollinate all of the blossoms because a tree will produce far more blossoms than it can support the fruit of and you will get better fruit if only a few of the blossoms produce fruit.

    It has a pest, most likely scale or aphids. The stickiness is from the honeydew in which these insects secrete. Neem oil will take care of the problem.

    The amount of time time it takes for a lemon to ripen can vary depending on several things. First, different varieties have different ripening times (typically between 3-18 months). Second, the conditions the lemon is grown under can shorten or lengthen the time it takes for it to get ripe. Lemons are ripe and ready to pick once they have completely turned yellow. However, slightly green-yellow ones can still be picked and will normally ripen off the tree, provided they are large enough. They should also be somewhat heavy feeling and hard with a ‘glossy’ look to them. If it’s kind of squishy, you’ve waited too long. The lemon should also be about 2-3 inches in diameter.

    It sounds like you may have a pest problem, likely mites, which can be hard to see. I would treat the plant with a pesticide and a mitecide. Neem oil is good because it is both a pesticide and a mitecide plus it is organic.

    There are a couple of reasons this can happen.

    First, the tree may not be mature enough to bloom. It need to be about 6 years old before it is able to bloom.

    Second, there may be too much nitrogen or too little phosphorous in the soil around the tree. I would recommend having the soil tested and adding some bone meal to around the base of the tree.

    You would be best to spray all the plants down completely. If he was wholesale sparying, there is a good chance that there was overspray and it may be killing the plants. Drenching the soil will also help to leech out any chemicals that are in the soil.

    Thank you! I sprayed them all down really well as suggested and moved the plants away from where he sprayed (they are in containers). They all appear to be doing fine a week later. I appreciate your help :)

    You can normally encourage branching by snipping out the top bud, which gives the side buds a better chance to grow.
