🪴 Orchid Soil pH: Optimal Range

🌿 Soil pH

The ⚖️ acidity level of the medium is a crucial element in the vitality and development of these plants. The ideal acidity range for their medium is between 5.5 and 6.0. This range ensures that the medium is slightly acidic, which is necessary for the proper absorption of nutrients by the roots. If the acidity is too high or too low, the plant may not be able to absorb the nutrients it needs, leading to poor development and overall vitality. It is crucial to routinely check the acidity level of the medium and make any necessary corrections to ensure the best conditions for your plants.

There are various techniques at your disposal. One alternative is to use 🧪 test strips, which are user-friendly and deliver a quick and accurate reading. Another choice is to use a meter, which is more precise but might be more costly. The ‘pour-thru’ technique is particularly useful for examining the acidity 🐂 of the medium as it doesn’t disturb the roots. This method involves pouring water through the medium and then testing the acidity of the water that emerges.

Techniques:

Use test strips
Use a meter
Use the ‘pour-thru’ technique

To raise the acidity 🐂 of the medium, you can use lime or oyster shell. These natural substances will help to increase the acidity, bringing it into the optimal range for your plants.

It is necessary to follow the instructions on the packaging and to only use the recommended amount, as too much can be damaging to the plant.

When it comes to hydrating your plants, it is essential to use the appropriate type of water to maintain the acidity of the medium. Rainwater or reverse osmosis (RO) water are the best options as they are free of dissolved solids and chemicals that can alter acidity. These types of water will help to ensure that the acidity of the medium remains in the optimal range for your plants.

🌿 Tap water

However, it is essential to note that tap water can influence the 🐂 acidity of the medium. Tap water contains varying levels of dissolved solids and chemicals, which can alter the acidity depending on the water’s composition. This is why it is crucial to routinely check the acidity of your medium and make any necessary corrections to ensure the best conditions for your plants.

Nutrients 🍲 can also have a significant influence on the 🐂 acidity of the medium. Some nutrients, especially those that contain urea, can make the medium too acidic when used with pure water.

It is essential to use a meter or test kit to track the acidity of your medium and make any necessary corrections to ensure the best growing conditions for your plants.
