The Best Petunia Fertilizer For Blooms That Last

Petunias are one of the most popular flowering plants in the world, and for good reason. They are easy to grow, come in a wide variety of colors, and bloom prolifically all summer long. However, in order to keep your petunias looking their best, they need to be fertilized regularly.

The best fertilizer for petunias is one that is high in phosphorus. Phosphorus is essential for flower production, and it helps to promote strong root growth. A balanced fertilizer with an N-P-K ratio of 10-20-10 or 15-30-15 is a good choice for petunias.

There are a variety of different fertilizers available, both liquid and granular. Liquid fertilizers are easy to apply, but they can be more expensive. Granular fertilizers are less expensive, but they can be more difficult to apply evenly.

No matter what type of fertilizer you choose, it is important to follow the directions on the label. Over-fertilizing can actually damage your petunias.

In addition to fertilizer, petunias also need plenty of water and sunlight. Water your petunias regularly, especially during hot, dry weather. And make sure they are planted in a location that gets at least 6 hours of sunlight per day.

With proper care, your petunias will bloom all summer long.
