9 Tips for Feeding Plants in Containers

Hey there, fellow plant lovers! If you're like us and enjoy growing plants in containers, you know how important it is to keep them well-fed. But it's not always as straightforward as it seems. There are many factors to consider, from the type of nutrients to the feeding frequency. In this blog, we'll share some useful tips to help you keep your container plants healthy and thriving.

1. Don't Rely on Standard Feeding Schedules

 

Manufacturers often provide feeding schedules on their product labels, but these are just general guidelines. The truth is, that every plant is different, and its nutritional needs can vary depending on factors like light levels, plant size, and growth stage. For example, plants in lower light conditions generally require less nutrients than those in bright light. So, instead of blindly following the schedule, observe your plants closely. Look for signs of nutrient deficiency or excess, such as yellowing leaves or stunted growth, and adjust the feeding accordingly.

 

2. Start Small and Adjust

 

When it comes to feeding plants, less is often more. Plants have a natural ability to absorb the nutrients they need and reject the ones they don't. So, it's a good idea to start with a small amount of fertilizer and gradually increase it if needed. A good rule of thumb is to start with a quarter or half of the recommended dosage and see how your plants respond. If they look healthy and are growing well, you can stick with that amount. If not, you can slowly increase the dosage over time.

 

3. Monitor Plant Health

 

Regularly checking your plants for signs of stress or nutrient deficiencies is crucial. Pale or yellowing leaves, slow growth, or weak stems can all indicate that your plants need more nutrients. On the other hand, if the leaves are turning brown or burned at the edges, it could be a sign of over-fertilization. By keeping a close eye on your plants, you can catch these issues early and take corrective action.

 

4. Measure Nutrient Levels

 

Using a meter to measure the electrical conductivity (EC) or parts per million (ppm) of your nutrient solution can help you ensure that you're providing the right amount of nutrients. Different plants have different nutrient requirements, and measuring the nutrient levels can help you tailor the feeding to the specific needs of your plants. Just make sure to use a meter that is appropriate for your growing system and follow the manufacturer's instructions for calibration and use.

5. Adjust the pH Level

 

The pH level of the nutrient solution can also affect the availability of nutrients to your plants. Most plants prefer a slightly acidic to neutral pH range, typically between 5.5 and 7.0. If the pH is too high or too low, it can prevent the plants from absorbing certain nutrients. You can use a pH meter, litmus paper, or pH testing drops to check the pH level of your nutrient solution. If it's outside the optimal range, you can adjust it using pH up or pH down solutions available at your local gardening store.

 

6. Use High - Quality Water

 

The quality of the water you use to feed your plants can also have a big impact on their health. Tap water often contains chlorine, chloramines, and other chemicals that can be harmful to beneficial organisms in the soil and your plants. So, it's a good idea to use filtered or distilled water or let the tap water sit out for 24 hours to allow the chemicals to evaporate. Additionally, make sure the water is at room temperature before using it to feed your plants, as cold water can shock the roots.

 

7. Consider Beneficial Organisms

 

Beneficial organisms, such as fungi, bacteria, and nematodes, can play a crucial role in plant health. They help to break down organic matter, improve soil structure, and protect plants from pests and diseases. You can introduce beneficial organisms to your container plants by using organic fertilizers, compost, or beneficial microorganism products. Just make sure to follow the instructions carefully and avoid using products that contain harmful chemicals.

 

8. Flush the Growing Medium

 

Over time, salts and other impurities can build up in the growing medium, which can affect plant growth. Flushing the growing medium with clean water can help to remove these impurities and prevent them from causing problems. To flush the growing medium, simply pour a large amount of water through the container and let it drain out completely. You may need to repeat this process several times to ensure that all the impurities are removed.

 

9. Follow Good Laboratory Practices

 

When handling and mixing nutrients, it's important to follow good laboratory practices to avoid contamination and ensure the safety of your plants. Always wash your hands before and after handling nutrients, and use clean equipment. Never pour unused nutrient solution back into the bottle, as this can contaminate the entire batch. And make sure to store nutrients in a cool, dry place away from direct sunlight.

 

By following these tips, you can ensure that your container plants receive the right amount of nutrients at the right time, helping them to grow healthy and strong. Remember, every plant is unique, so it may take some trial and error to find the feeding routine that works best for your plants. But with a little patience and attention, you'll be able to enjoy beautiful, thriving container plants in no time.
