If your citrus trees leaves are green, then they likely don’t need much fertilizer (although it’s still a good idea to provide a supplemental 1-2 inches of compost in the spring). If the adventure feels daunting you can start slowly with one of these three “easiest to grow” trees: Eureka lemon , Bearss lime , Trovita orange .

Citrus Trees: Best Soil Mix, pH How to Prepare the Soil for Citrus Trees: Best Soil Mix, pH

The amount of water vapour in the atmosphere. Different plants require different levels of humidity. Houseplants that need high humidity are best grown in a steamy bathroom, misted regularly or the pot placed in a saucer of damp pebbles. In a greenhouse, humidity can be raised in hot weather by damping down (wetting) the floor, overhead watering or misting. However, high humidity can cause fungal problems, in which case open vents to improve ventilation. humidity up year round. The best way to do this, is to stand plants on large saucers or trays filled with ‘Hortag’ or gravel and keep the water level just below the surface of the gravel. Mist the leaves in early morning in summer and make sure that there is good circulation of fresh air. Citrus trees will typically outgrow their pot every 3-4 years, and while you can use the old potting soil, it’s best if you provide a fresh mix.

Aeration also allows for carbon dioxide and other gasses that are a byproduct of decomposition to escape and not get trapped in the soil. A potting mix that isn’t properly aerated will become compacted, stunting root growth and preventing water from draining.

In winter, when plants are indoors, allow the surface of the compost to partially dry out before watering, then water thoroughly with tepid rainwater, allowing the excess to drain away. Overwatering in winter is one of the commonest problems, so err on the dry side. And never leave pots standing in water, as this can cause the roots to rot. Yellowing of the leaves or shedding leaves can be signs of overwatering. Use a soil mix that is lightweight and drains well. If the mix contains a large proportion of dense, absorbent material, such as peat moss or worm castings, amend with 1/4-1/3 volume of 1" cedar or redwood shavings. Water in thoroughly, using Vitamin B-1 rooting tonic in the first few applications, if desired. Once the roots have settled, we prefer using slow-release fertilizers applied to the soil surface, rather than mixing fertilizer into the soil or using plant stakes. This avoids any risk of burning the roots. Romeo fertilizer is what the trees are grown within the nursery and has proven to do extremely well on container citrus when applied monthly during the growing season.

Whichever soil mix you choose, know that you can’t really go wrong. Just make sure to have a rich, slightly acidic, and well-draining soil, and your citrus tree will be happy for years on end! How to Transplant the Tree With the New Soil Do you live in a very dry climate? Maybe add a little more of the water-retentive ingredients (peat moss, compost, etc.). Does it seem too dense or heavy? Mix in some extra perlite or pine bark. You can also customize what kind of fertilizer you want to include, depending on the needs of the tree. Your tree should also receive an average of 8 hours of sunlight a day. The roots can be pruned to make room for other plants, but be careful not to harm the trunk or branches. To ensure proper growth, it is essential to know how to make potting soil for citrus trees. I just bought a small key lime tree, and I would like to plant it in a pot and bring it outdoors. What kind of growing medium is the best for it, I do have a bag of the orchid growing mix that has the bark, and also what kind of food do I feed it, and how big does the pot have to be for it? The one that it is in is a 4″ pot. For growing young citrus trees in containers, we recommend a 12-14" pot to start. This includes our Primo trees. A variety of decorative plastic containers are available at reasonable prices. Clay pots and wooden containers are attractive but less mobile choices. When selecting a container, be sure there are sufficient drainage holes . Drilling extra holes is an easy way to improve drainage with wood or plastic. As the tree grows, increase the container size to a 16-20" diameter pot (the next pot size up). Do not start with a pot that is too large as it makes soil moisture levels harder to control with small trees.
