Can you successfully grow a lemon tree in a big planter pot? How do you look after it and also are there plants/herbs that can be grown in the same container as a lemon tree that has only a small trunk?
Citrus plants grow very well in containers and to keep them healthy you need to consider; pot size, soil mix, fertilising and watering. Choosing the right sized container for your tree is important and depends on the size of the plant. With regular varieties plant into a container large enough to let the root system spread out comfortably. Every 3-5 years you will need to re-pot your citrus into a larger container as the roots will fill the existing container and limit the trees ability to absorb nutrients and water.
Always use a good quality potting mix, such as Daltons Premium Container Mix. These mixes are specifically designed for pots and will give consistent nutrients and drainage throughout. Add good layer of Daltons Mulch and Grow on top (but not touching the trunk of your tree) to help with moisture retention and stop pots drying out. Because citrus are known as 'heavy feeders' they respond well to regular application of specific citrus fertiliser. Apply Daltons incredible edibles® Citrus Fertiliser every 4-6 weeks from late October to Christmas, recommencing late February through to mid-April.
Regular watering is critical to help develop good quality fruit, especially during periods of insufficient rainfall. Remember to give trees regular deep watering, and increase this during the summer months.
While it’s possible to plant herbs and other plants in the same container, it is not recommended because the lemon trees roots are just below the soils surface and will compete for the available nutrients and moisture.
