Pot size for a Meyer lemon tree (Citrus x meyeri) depends on its age, the desired size and shape of the tree, and the production of fruits. It is important to have a pot that is large enough to contain the root system, but not so big that the soil in the pot remains wet for too long. Here are some tips on the size of pot you should use for a Meyer lemon tree.
Pot Size for a Young Meyer Lemon Tree
For a young Meyer lemon tree, use either a 16- to 20-inch-wide pot for a single tree, or a 24- to 32-inch-wide pot for a multi-trunk tree. Make sure the pot has multiple drainage holes to help with excessive moisture. It should have a depth of at least 8 to 9 inches to make sure the roots have enough room to grow. While you may be tempted to use a larger pot to promote growth, a pot that is too large can cause root rot, as the soil in the pot will remain too moist for too long.
Pot Size for Established Trees
Most established Meyer lemon trees should be in a 20- or 24-inch pot. For an extra large tree in a 25- to 30-inch pot, you may need to tie the main trunk to stakes already in the pot to support it. For an extra tall tree, you may need to repot it into a barrel. Just make sure the barrel has several drainage holes at the bottom so excess water can escape.
Keep Repotting Every Few Years
Meyer lemon trees should be repotted every 2 to 3 years to keep the root system healthy and promote fruiting. When repotting a lemon tree, use a slightly larger pot and a soil mixture that drains well, like equal parts sand and potting soil, and add some compost for added nutrients. Make sure to water the tree for a few days before repotting it so the roots don’t dry out.
Dealing With Overgrown Roots
If the root system of a Meyer lemon tree grows too large for its pot, you can prune the roots to make it fit. To do this, you need to turn the tree on its side and outer roots that are 1 to 2 inches in diameter can be cut with pruners. You can add new soil in the middle of the root ball to accommodate the smaller root mass.
Putting a Plant in the Right Pot
The right-sized pot is essential for the health and growth of a Meyer lemon tree. While it may be tempting to choose an oversized pot, it is important to pick one that is just the right size, or a bit larger. The soil should be kept mostly dry, but not overly dry, to ensure the health of the roots. Repotting should be done every 2 to 3 years, and the root system should be pruned if necessary in order to fit in the pot.
Add Mulch For Optimal Drainage
For optimal drainage and to retain moisture, it is important to add mulch to the top of the potting soil. Organic mulch such as leaves, pine needles, and sawdust will help to breakdown, improving the soil structure and water retention. This will prevent the soil from becoming waterlogged and help to protect the roots from freezing temperatures.
Provide Regular Watering and Fertilizing
Meyer lemon trees need regular watering and fertilizing to produce an abundance of lemons. Water the tree when the soil begins to dry, ensuring that you water deeply to the bottom of the pot. Fertilizing should also be done regularly, usually in spring and summer when the tree is actively growing. A liquid fertilizer with nitrogen and other essential minerals is ideal for a Meyer lemon tree.
