How to promote root growth on vanda orchids?

Root growth is an important aspect of orchid care. When the roots are healthy, orchids can take up more water and nutrients, which can help them survive in dry environments.

We’ll discuss seven things that you can do to promote root growth in vanda orchids:

01. Choose the Right Pot

Before promoting root growth on vanda orchids, you must choose the right pot for the plant. You should select a pot at least 12 inches in diameter and six inches deep. The pot should have drainage holes and a quality soil mix. 

02. Choose the Right Soil

Many types of soils can be used for vanda orchids. The ideal soil is well-drained and has a high organic content. Some common soils that can be used for orchids include sphagnum moss, bark mulch, and compost. It is important to mix the soil before planting the orchid to have a good balance of textures and nutrients.

03. Water Properly

Most orchids, like vanda orchids, appreciate regular watering. Watering should be done while the plant is in a pot or on the ground. Use a watering can, hose attachment, rain barrel, or faucet with a water dispersal device. Make sure the water reaches the root zone of the plant. Check the potting mix and make sure it is moist but not wet. Allow the plants to dry out between waterings if you live in a hot climate.

04. Fertilize With Organic Matter

It is generally recommended to fertilize orchid plants with a high-quality organic fertilizer. Fertilize your vanda orchid every two to three months with a balanced fertilizer specifically formulated for orchids, using a high-potash formula if available. Do not use manure, compost, Epsom salts, citrus fruit juices, or any other type of fertilizer high in nitrogen; these will only encourage foliage growth at the expense of root development.

05. Deal with Pests and diseases

You can do a few things to help promote root growth on vanda orchids. One is to deal with pests and diseases. Pests can damage the plant, while diseases can cause it to die. You can also take steps to improve the soil conditions for your vanda orchid. Improving the soil will help provide the plant’s nutrients and moisture to grow healthy roots.

06. Keep an Eye on Temperature

Temperature is an important factor to consider when promoting root growth in vanda orchids. Too cold and the roots may not grow, while too warm and the orchid may overheat. A temperature range that is comfortable for the orchid but not too warm or cold is ideal.

07. Prune When Necessary

Pruning is essential for keeping your vanda orchid healthy and ensuring the plant can take up more water and nutrients. Prune back branches growing beyond the desired size and remove dead leaves and flowers. Pruning will also help to reduce stress on the plant.

The benefits of Promoting Root Growth On Vanda Orchids

When it comes to orchids, one of the most important things you can do to promote healthy growth is to encourage strong root development. This is especially true for vanda orchids, known for their notoriously finicky roots.

There are a few key benefits to promoting root growth in vanda orchids:

1. Increased nutrient uptake: Healthy roots can absorb nutrients from the soil more effectively, leading to a healthier overall plant.

2. Better water uptake: Strong roots can take up water from the soil, helping to keep the plant hydrated and preventing wilting.

3. Greater stability: A plant with strong roots is less likely to blow over in the wind or be uprooted by a passing animal.

4. More flowers: A vanda orchid with a robust root system is more likely to produce an abundance of flowers.

Why is my orchid not growing roots?

An orchid might not be growing roots because the plant is not getting enough water. Orchids need plenty of water to grow healthy roots; if they don’t get it, they will stop growing.

Second, even if an orchid does not need direct sunlight, it still needs some light to grow.

Do orchids need air roots?

Orchids do not need air roots to grow. However, some orchids have aerial roots that help them absorb more nutrients from the soil. These aerial roots typically grow from the base of the plant and hang down into the soil. They help the plant absorb more water and minerals from the soil, which can help it grow better.


In conclusion, you can do a few things to promote root growth in vanda orchids. Ensure the potting medium is well-draining and keep the plant in a warm, humid environment. Feed the plant regularly with a balanced orchid fertilizer, and mist the leaves often. If you follow these tips, your vanda orchid will thrive and produce beautiful blooms.
