How much sunlight does an African Milk Tree need?

Back to top

African milk tree in the sun Most cacti and succulents love warm and dry climates. They thrive off neglect and are true sunbathers. The same goes for the African Milk Tree!

In terms of lighting, African milk trees do best in bright, direct light. They can tolerate indirect sunlight as well, but this plant thrives in direct sunlight and loves to receive several hours of bright sun during the afternoon. If you live in a colder climate, it's best to keep your African milk tree near a bright light source, like a west- or south-facing window.

Providing enough light can be difficult in autumn and winter, depending on where you live. If your African milk tree isn't getting enough natural sunlight, you can use a grow light to help keep it happy. You can also move your Milk tree closer to a window, so it's exposed to a little bit more sunlight. During the summer this would be too much sunlight, but this is perfect during the autumn and winter.

How to water an African Milk Tree

Back to top

African milk tree size Cacti and succulents are plants that love to be neglected and prefer it when you forget about them for weeks at a time. These types of plants thrive in warm and dry climates, which means they also don't like to get watered very often.

To water your African milk tree, wait until the soil is dry to the touch. Then, water your plant thoroughly, making sure that the water drains out of the bottom of the pot. A drainage hole is very important for drought-loving plants because it removes the excess moisture from the soil. This plant will not tolerate wet feet! Allow the plant to dry out completely before watering again.

African milk trees are drought tolerant and can withstand long periods without water. No need to worry if you're away for a week! However, they will grow faster and produce more flowers if they're given a good soaking every week or two in the summer. You may need to water your African milk tree more frequently if you live in a hot, dry climate.

During the winter, you won't need to water your African Milk Tree as much, as plants slow down their growth. Be sure to check whether the soil of your Milk tree is dry before you water your plant. This will generally take a little longer during the winter. On average, you'll water your plant every 2-3 weeks.

What is the best type of soil for an African Milk Tree?

Back to top

The best type of soil for an African milk tree is loose, well-draining potting soil. You can find potting soil specifically designed for cacti and succulents at your local garden center. Be sure to avoid using garden soil or soil from outdoors, as these soils are often too dense and will not drain properly.

Instead of buying pre-mixed cactus/succulent soil, you can also choose to mix it yourself. The perfect mix for this consists of 3 parts of potting soil, 3 parts of coarse sand, and 2 parts of pumice or perlite. This creates a very well-draining potting soil that will drain the excess moisture to the bottom of the pot quickly while holding onto a little bit of moisture in the potting soil for your African Milk Tree.

How to fertilize an African Milk Tree

African milk tree soil

African milk trees are not heavy feeders, so you don't need to fertilize them very often. Once every two or three months is usually sufficient. When you do fertilize them, there are a few options for the type of fertilizer you can use.

The best option is to use a special cactus or succulent fertilizer. You can also use a 10-10-10 fertilizer, however, this should only be used during the growing season (the spring and summer). The best type of fertilizer that I've found is a liquid fertilizer. It's very convenient because you can add it to the water you're watering your plants with. Liquid fertilizer also helps you to control the dose of fertilizer. This prevents overfertilizing.

How to transplant an African Milk Tree

Back to top

When your African milk tree starts to outgrow its pot, it's time for a transplant. Choose a new pot that is only one size larger than the current pot. If the tree is in a pot that's too large, the roots can begin to rot. Be sure to use a cactus or succulent potting mix and make sure that the pot has drainage holes.

Gently remove the tree by grasping the base and carefully pull the milk tree from its pot. Depending on the size of your milk tree, you may need someone to help you support the plant as you place it in the new pot. Once the tree has been moved, fill it with the fresh potting mix and water well.

The best time to transplant an African Milk Tree is in the spring when it has a whole growing season ahead of it. It'll make the transition much easier and helps the African Milk Tree to settle in more easily.

What pests and diseases can affect an African Milk Tree

Back to top

As with all plants, it's important to check your African milk tree for pests and diseases regularly. If you notice any problems, treat them immediately.

Pests that can affect an African milk tree include spider mites, mealybugs, whiteflies, or scale. If you notice any of these pests on your plant, treat them immediately with a pesticide or insecticidal soap.

If you notice any of the following signs on your African milk tree, the tree likely has pests:

  • Leaves that are wilting or browning
  • Sudden loss of leaves
  • Dead branches or shoots
  • Honeydew deposits on leaves or branches
  • Swelling or distortion of bark
  • Webbing between branches

If you're unsure about the different pests that might be affecting your African Milk Tree, it's always a good idea to take a photo of the pest and show it to the employees of your local garden store. You can also share the photo on our Facebook Page to get help from other members!
