Superphosphate -- Partly soluble in water and quickly available for plant use.
Potassium -- An essential element deficient in our sandy soils.
Superphosphate: 13-20% phosphorous. Base dressing. Best source of phosphates. Keep off of leaves. Don’t mix with sodium nitrate.
Urea: 46% nitrogen. Liquid feed.
A superphosphate is a fertilizer that contains a blend of ground phosphate rock and sulfuric.
Ideas for Weed Control in Gardens Using Fabric
Landscape and gardening fabrics are designed to suppress weed growth while allowing water and air.
An application of superphosphate in early spring
Severe pruning of the new growth in late spring or early summer
Root pruning by cutting some of the roots with a spade a few feet from the trunk in late fall.
Grafted plants or plants that have flowered in the nursery are recommended.
A half cup of a good plant food (10-6-4), bone meal or superphosphate should be mixed into this layer.
You should avoid adding fertilizer to the soil that will be in direct contact with the roots.
of 0-46-0 (triple superphosphate) or 2 lbs. of 0-20-0 (superphosphate) fertilizer per 50 feet of row in the bottom of the furrow before planting. This will make phosphorus immediately available to the crowns.
Mix a handful of bone meal or superphosphate into the soil you removed from the hole and save it for refilling the hole, once the rose is planted.. This will help the rose bush acclimate to its new home. Don't feed with anything else at planting time.
This trial shows that even two single grains of superphosphate in a pot are enough to cause classical phosphorous toxicity symptoms, such as yellowing new growth and browning on the edges of the old foliage.
When you start a new lawn, landscape, vegetable or flower garden, prepare the soil well by rototilling in organic materials and phosphate fertilizers. Superphosphate and treble phosphate are much more effective under local soils than is bone meal (calcium phosphate).

When 8" tall apply 2 lbs. of urea or ammonium sulfate per 100 sq. ft. When silk appears add 2 lbs of superphosphate.
Add compost or well rotted manure.
The choice of fertilzer will also affect the color change. A fertilizer low in phosphorus and high in potassium is helpful in producing a good blue color(25/5/30 is good. Potassium is the last number). Superphosphates and bone meal should be avoided when trying to produce blue.
Start by sowing raw (not roasted) peanuts into well- drained soil. Sprinkle Thrive Granular All Purpose plant food and some extra superphosphate beside the rows. Mulch well to retain moisture and feed the plants by regularly watering with soluble Thrive or Aquasol.
This mixture should be pasteurized at or about 180?F for 30 minutes. You alsocan buy a premixed, pasteurized media. If you are mixing your own soil, add oneteaspoon of superphosphate or bone meal for every 2 1/2 cups of soil mixture andthoroughly mix in.
Flowers can be made (or kept) blue by applying aluminum sulfate to the soil, kept red (or pink) or made redder by liming the soil or applying superphosphate in quantity. Flower-color treatment is not effective unless started well ahead of bloom.
