You may see a lot of plant food products as you're browsing the floral section of your favorite stores. Nearly all plants will benefit from regular feedings with the right products. Most types of plant food contain the three most essential nutrients — nitrogen, phosphorus, and potassium. Calcium and magnesium are included in many plant foods as well. As mentioned above, researching the plants in your garden will give you a more detailed idea of what they need. Even potted plants need plant food. The limited amount of soil they have access to in your home can become depleted quickly. Feed your plants just as you water them to make sure they have everything they need to thrive. Order cut flowers, potted plants, and more through Instacart and add bright blooms to your home with delivery in as little as 2 hours.
