When to Start Fertilizing

You should make your first fertilizer application 7-10 days after transplanting in the bed or container. I suggest your initial feeding be Jack's Classic® All Purpose 20-20-20. It has equal parts of Nitrogen, Phosphorus and Potash along with all the trace elements they need. The rate for all outdoor plants is 1 tablespoon per gallon of water. Most watering cans hold two gallons so dissolve two tablespoons and apply the fertilizer solution around the base of the plants as a root area drench. You should put on as much of this solution as it would take for a good watering. Don't worry about getting any on the leaves because it will not burn your plants. Some fertilizer will be absorbed by the leaves, but the amount absorbed by the roots is much greater and more effectively used by the plant.

For all your annuals both flowers and vegetables you should feed every other week. Since hanging baskets require more frequent watering because they dry out so quickly and use up their nutrients I suggest fertilizing them every 10-14 days.

You can use all the Jack's Classic® products in the Miracle Gro feeder to cover large plantings. Remember that with this type of feeder the fertilizer solution is stronger in the beginning and weaker at the end. With that in mind make sure you distribute your spray solution uniformly by going back and forth repeatedly over the area being fertilized. Fill the sprayer with about 1pound of Jack's Classic® Products and follow the sprayer directions. For the type of sprayer that has a siphon tube, follow the directions to get a final feed rate of 1 tablespoon per gallon.

Bedding Plants Use 20-20-20 All Purpose or 10-30-20 Blossom Booster every 2 weeks.
Container Gardens Usually these are planted in a soilless mix (lightweight potting soil). Use 10-30-20 Blossom Booster every 10 days especially for baskets that need frequent watering.
Trees and Schrubs Use 20-20-20 All Purpose or 17-6-6 Acid Special once a month. Make an application early in the season timed with the typical growth spurt. Pin Oaks in particular thrive on the 17-6-6 Acid Special with its low pH, sulfur and available trace elements
