It is dissolved in water and applied as a liquid feed to soil or foliage. Follow the label rate for the plant type, since the mix is concentrated.

Can I use it on tomatoes and squash?

Yes. The phosphorus and potassium support flowering and fruit set, and the nitrogen keeps vines growing. Avoid overfeeding, which pushes leaves at the expense of fruit.

No. It is derived from urea, ammonium phosphates and potassium nitrate, all synthetic sources.

Can I use it on houseplants?

Yes, at a diluted rate. Water-soluble feeding suits container plants, but flush the soil occasionally to avoid salt buildup.

Does it work on lawns?

Yes, it can be applied as a liquid feed to turf. The high nitrogen greens grass quickly, so apply evenly to avoid streaks.

Our take on the Southern Ag Powerpak Water Soluble Fertilizer 20-20-20

Southern Ag Powerpak is a water-soluble 20-20-20 fertilizer, an even blend of nitrogen, phosphorus and potassium that mixes into water for feeding roses, flowers, vegetables, lawns, trees, shrubs and houseplants. The nitrogen comes from urea and ammonium sources and the potassium from potassium nitrate, so it feeds both quick top growth and fruiting and flowering. It suits gardeners who want one general-purpose mix for beds, containers and lawns rather than separate formulas. Against single-purpose bloom or lawn fertilizers it is more versatile but less specialized, and it is not an organic product.
