How Often Should I Fertilize My Outdoor Pot Plants

Whether you are growing flowers, herbs or vegetables in outdoor pots, proper fertilization is crucial. Fertilizing your potted plants will ensure that they are receiving the necessary nutrients to grow and thrive. However, there is no “one size fits all” approach when it comes to fertilizing your outdoor pot plants. A lot of factors need to be taken into consideration including the type of plant, pot size, soil quality and moisture levels. In this article, we have compiled a comprehensive guide to help you determine how often you need to fertilize your outdoor pot plants.

Determine the Nutrient Needs of Your Plants

Before you start fertilizing your outdoor pot plants, you need to know what nutrients your plants require. Different types of plants have different nutrient requirements. For instance, flowering plants require a fertilizer that is high in phosphorus while leafy vegetables like spinach or kale require a fertilizer that is high in nitrogen. You can determine the nutrient needs of your plants by conducting a soil test or checking the packaging of the fertilizer.

Consider the Pot Size

The size of the pot plays a vital role in determining how often to fertilize your outdoor pot plants. If the pot is small, nutrients are likely to get exhausted quickly. Hence, it needs to be fertilized more often. On the other hand, if the pot is too large, it might retain more nutrients than the plant requires, leading to nutrient toxicity. A general rule of thumb is to fertilize small pots every two weeks while large pots can be fertilized every 3 to 4 weeks.

The Timing of Fertilization

The timing of fertilization is also important when it comes to outdoor pot plants. It is recommended to fertilize your potted plants during their growing season. During the growing season, plants require more nutrients to encourage growth, flowering or fruiting. For instance, if you are growing tomatoes in outdoor pots, fertilize them every 2 weeks during the growing season. However, once the growing season is over, reduce the frequency of fertilization or stop it completely. In the dormant season, plants do not require as many nutrients.

The Type of Fertilizer to Use

Choosing the right fertilizer is important for the health of your outdoor pot plants. There are three main types of fertilizers: granular, liquid and slow-release fertilizers. Granular fertilizers are sprinkled around the plant base and need to be watered in. Liquid fertilizers are added to the water and then given to the plants. Slow-release fertilizers are added to the soil and can last for several months, gradually releasing nutrients into the soil. Slow-release fertilizers can be great for outdoor pot plants as they do not require frequent fertilization.

The Importance of Watering

Proper watering is crucial in keeping your outdoor pot plants healthy. Over-fertilizing, coupled with inadequate watering, can lead to nutrient burn or even plant death. On the other hand, under-fertilization or over-watering can lead to nutrient deficiency issues. Hence, you should ensure that your plants are well-watered before and after fertilization. You should also check the moisture level of the soil regularly to determine whether or not to water your plants.

Conclusion

Fertilizing your outdoor pot plants is essential for their growth and overall health. Understanding the nutrient requirements of your plants, the pot size, fertilization timing and the type of fertilizer to use can guarantee success. Remember to keep your plants well-watered and to stay on top of the fertilization schedule during their growing season. When done correctly, fertilization can lead to beautiful, healthy plants that will thrive all summer long.
