Meyer lemon trees are a popular choice for those seeking an easy-to-care-for, relatively low-maintenance citrus plant. Proper hydration is an essential part of caring for a citrus tree, but how often should you water your Meyer lemon tree? The watering needs of a Meyer lemon tree vary significantly based on the size, age, and growing conditions of the tree. Generally speaking, however, Meyer lemon trees need to be watered deeply and infrequently, typically once every 7 to 10 days, or when the top 2 inches of soil are dry.
When it’s time to water your Meyer lemon tree, you should use plenty of water — about 15 gallons for a 5-gallon container. If your tree is in a larger container, divide the overall size of the container by 2 to determine the quantity of water you need. When watering your tree, it should be done slowly in order to encourage the water to penetrate deeply and to reach the dense root system of the tree. During active growth in the spring and summer, make sure to supplement deep watering with an occasional, light surface irrigation.
It’s important to make sure your Meyer lemon tree is getting enough water, but you also don’t want to over water it. Over-irrigation can cause the leaves to yellow and can render the soil too wet for the roots to access air and oxygen. If the potting mix feels overly-damp throughout, then it is likely that you are watering too much. Be sure to also monitor the drainage; Meyer lemon trees must be planted in well-draining soil that allows excess moisture to pass through. Otherwise, the roots can become waterlogged, leading to root rot.
In addition to knowing the correct frequency, it’s also important to pay attention to the soil conditions. While Meyer lemon trees should never be allowed to dry out, they should also not be overly-saturated either. Place your finger into the soil up to the second knuckle and if the soil is dry to the touch, then it’s time to water. Monitor the wet/dry cycles of your tree and adjust watering according to the changing conditions.
It’s also able to save time and effort by using a soil moisture meter or soil probe to easily check moisture levels without having to constantly dig up the soil by hand. Also, if your Meyer lemon tree is growing outdoors, consider using a drip irrigation system that works to slowly and evenly water the soil over a period of time.
Additionally, the use of mulch around the surface of the soil can help to hold in moisture and reduce the need for frequent watering. However, you must be sure to place the mulch around the drip line (the outer edge of the canopy), as mulch placed against the trunk of the tree can create a moist environment, leading to rot.
Soil Conditions
Soil conditions affects how often you should water your Meyer lemon tree. The type of potting soil that you choose is very important when it comes to caring for a Meyer lemon tree. As with garden soil, the potting soil should be light and drain easily. Sandy and loam mixtures are ideal, as these soils are able to hold just the right amount of moisture, and then quickly drain away any excess. When planting or repotting your Meyer lemon tree, make sure to use a soil that is formulated for citrus trees as this soil generally contains larger amounts of essential nutrients than other types of potting mix.
Location and Climate
Location and climate both play pivotal roles in determining the optimal watering needs of a Meyer lemon tree. In general, those growing in warmer climates will need more frequent deep waterings (up to twice a week) than trees growing in cooler climates. Additionally, growing Meyer lemon trees in partial shade is known to improve water retention and reduce the need for extra watering.
Yearly Water Requirement
A Meyer lemon tree grown in an ideal environment will generally require an average of 25 gallons of water per year, with heavier waterings during the warmer months and lighter waterings during the cooler months. This can vary significantly, however, depending on the climate, soil, size of the tree, and type of container that it is planted in. Make sure to constantly monitor your Meyer lemon tree’s watering needs and adjust watering schedules accordingly.
Fertilizing Your Meyer Lemon Tree
In addition to adequate water, fertilizing your Meyer lemon tree with a citrus-specific fertilizer is essential for optimal health and growth. Fertilizing should generally take place from mid-January through mid-August, but always be sure to adhere to the instructions on the specific fertilizer that you choose. Additionally, it’s important to always water the tree well before and after applying fertilizer for optimal absorption and to ensure that it does not burn the tree’s roots.
Signs of Under-Watering and Over-Watering
Signs of under-watering and over-watering in Meyer lemon trees include yellowing leaves, leaf drop, and withered fruit. Additionally, if the tree is being over-watered, it may be suffering from root-rot, which is typically signaled by wilting or limp leaves, sluggish growth, and general lack of vitality. Signs of under-watering a Meyer lemon tree include droopy leaves, leaf scorch, and dry, corky bark. If your tree appears to be experiencing any of these symptoms, adjust your watering schedule accordingly in order to get it back to optimal health and vigor.
