In addition to their all-purpose fertilizer, Jobe’s also offers specialized water-soluble plant food for specific plant types like tomatoes, azaleas, and orchids.

Jobe’s Organics Water-Soluble All Purpose Fertilizer is an organic, environmentally friendly, water-soluble solution for healthy, beautiful plants.

Jobe’s Organics

While not a granular fertilizer, the powder in Jobe’s Plant Food is not as fine as some of the other options (like Miracle-Gro Nature’s Care). The coarser grains are less likely to blow away in the wind if you’re mixing up the liquid fertilizer outdoors. It can be a bit more difficult to dissolve than the finer powders. Jobe’s can be a bit messy to use since the plastic liner bag is not resealable (a wooden clothespin works well).

Jobe’s organic fertilizer has a proven track record and is available in garden centers across the continent. Even their all-purpose fertilizer includes specific water mixing instructions for different types of plants, including flowers, vegetables, roses, and houseplants. Jobe’s plant foods are OMRI listed for organic gardening by the USDA. Jobe’s Organics is headquartered in Texas with additional manufacturing in Kentucky.

Using Water Soluble Fertilizer for Fruit Trees

What are Water Soluble Fertilizers

Most water-soluble fertilizer in stores today is synthetically manufactured from oil. These synthetic fertilizers are not approved for organic gardening. The concentrated chemicals can burn plants instead of helping them (not to mention beneficial critters and earthworms). These synthetic chemicals are generally manufactured in commercial chemical plants from a petroleum-based feedstock. 

While synthetic fertilizers do provide giant amounts of NPK, they skimp on all the other important nutrients. Organic options are more likely to provide important trace nutrients, beneficial bacteria, and mycorrhizae. OMRI-listed water-soluble organic fertilizer is a safer alternative for your garden and for the overall environment.

Organic products can be just as quick and effective as synthetic products at providing nutrients to your plants. Natural fertilizers provide plants with the big three nutrients (N-P-K) as well as other less-famous (but still important) nutrients. Organic water-soluble fertilizers are less likely to contribute to the pollution of waterways and much more likely encourage a healthy soil environment for the long-term
