So it is vital that your soil be well drained. We recommend a moist loam soil for our potted citrus. However, citrus can be successfully grown in a wide range of soil types including clay and sand. Whatever the soil type, make sure the top few inches are dry before watering. Water should be applied thoroughly so that the entire rootball is drenched.
Citrus also needs room to grow.
If you're planting in the ground, a good rule of thumb is to give each citrus a 12 by 12-foot area in which to grow. In pots, size requirements vary. For example, our Calamondins are shipped in one-gallon containers. Pruned annually, the containers will suffice. Your plants should also receive the micronutrients iron, zinc and manganese.
