The foliage on garden plants will reveal everything a gardener needs to know about the health of the plant and the condition of the garden soil. If a garden plant’s foliage is not healthy and green, first examine for pest infestation. If pests are not found, it’s time to look deeper into the garden soil to diagnose the garden plant’s problem.
Pale Green Or Yellow Plant Leaves
When a garden plant should be producing bright green leaves but the leaves are turning pale or yellowing, the plant is not getting enough nitrogen from the garden soil. If the nitrogen deficiency is not corrected, the garden plant will be severely stunted.
Add nitrogen to the soil by side dressing the garden plant with a granulated fertilize that is high in nitrogen, or for more immediate results, Mix one once of the granulate high-nitrogen fertilize in two gallons of water and water plants weekly with the mixture.
If too much nitrogen is present in the garden soil, plants will be lush green, but produce spindly growth and very few blooms.
Yellow Leaf Edges With Brown Tips
When the edges of plant leaves turn yellow, have brown tips and proceed to fall off the plant, the plant is not receiving enough phosphorus from the garden soil. Apply one cup of bone meal as a side dressing to the plants or mix a water soluble super-phosphate product and apply to plants according to manufacturer’s directions.
Yellow Spotted Plant Leaves With Brown Edges
Yellow spotted or yellow mottled plant leaves that develop brown edges indicates the plant is not receiving enough potash from the garden soil. Scatter one tablespoon of potassium sulfate around each plant that has this problem and water the potassium sulfate in well.
Plant Leaves Begin Darkening At Stem Base And Die
When a plant’s leaves begin to turn dark green at the stem base and continue to darken to the edges and fall off, this indicates the garden plant’s feeder roots are dying for lack of calcium. Get calcium directly to the plant’s feeder roots by dissolving ½ cup of Epsom salts in a gallon of water and use to water the plant well, or sprinkle ½ cup of dolomite lime around the plant and water in well.
Plant Leaves Yellow But Veins Remain Green
The garden plant has an iron deficiency. Mix one tablespoon of iron sulfate in one quart of water and use entire quart of water for each garden plant that has this problem.
Red Or Yellow Leaf Centers Followed By Black Spots
The garden soil is not providing the plant with enough magnesium. A dose of Epsom salts ( ½ cup per gallon of water) will remedy this plant problem. Epsom salts is calcium-magnesium and works to solve many garden plant problems, plus it promotes new roots growth for all plants.
Leaf Veins Lighter Than Leaf Tissue
The garden soil is lacking in sulfur. A dose of sulfur dust worked into the soil around the plant will correct the problem and bring health back to the plant.
Garden plant problems can be diagnosed by looking at the plant leaves and tracing the problem back to the garden soil for correction.
