This fertilizer has an NPK of 10-5-15, so it offers a lot of nitrogen and potassium to crops and is also ideally suited for use on any fruiting vegetables. The high nitrogen and potassium content makes it a great option for many vegetables and fruit, particularly the likes of tomatoes, peppers, eggplant, squash, and pumpkins.Ī granular example of an all-purpose feed that is ideal for the vegetable garden is the Miracle Gro Shake 'N Feed Tomato, Fruit & Vegetable Plant Food available at Amazon (opens in new tab), which is scattered on the surface and mixed into the soil. It has an NPK of 24-8-16 and offers all the vital nutrients vegetables need to grow strong and healthy. This feed comes in liquid form and is mixed with water to be added to vegetables. One example is the Expert Gardener All-Purpose Water Soluble Plant Food available from Walmart (opens in new tab).

These products all offer vital nutrients to plants and will help them grow. They come in either granular or liquid soluble form and tend to contain all three of the essential plant nutrients. There is a range of inorganic all-purpose plant food available in stores and online. (Image credit: Getty/Alexandra Ribeiro / EyeEm) 9.
