Prof. Charles Hartman, Ph.D.Correcting soil pH levels in the garden takes care, lest precious plants suffer. Often, remedies for one malady create another. I've seen gardens twirling in their heavenly joys through ill-timed makeshifts. Take cognizance, and there will be much saved in time and expense, to say nothing of being good to the plants.
Over-Application Hazards
- Excess lime locks manganese and boron
- Causes micronutrient deficiencies within weeks
- Requires months of corrective flushing
Temporary Fix Fallout
- Vinegar drops pH briefly then rebounds
- Baking soda increases sodium toxicity
- Damages soil structure and microbiology
Retesting Neglect
- pH continues changing weeks after application
- Misses over-correction causing new imbalances
- Wastes amendment materials unnecessarily
Plant-Ignorant Adjustments
- Raises pH for acid-loving blueberries
- Lowers pH for alkaline-preferring cabbage
- Creates multiple nutrient lockouts
The excessive use of lime can lead to alkaline poisoning. The excess of calcium combined with phosphorus and zinc. I corrected this issue by applying a combination of sulfur and compost for a period of three months. Phosphate magnetic compositions must, in all circumstances, be based upon soil analyses, never left to guesswork. Be very careful to have your garden measured correctly before operations are undertaken.
In the case of any mistakes, correct them with great care. For soil that is over-limed, apply sulfur gradually. Deep watering flushes temporary fixes. If the plant's needs were neglected, transplant the specimens to the appropriate areas. Make note of each adjustment for future reference.
Avoid mistakes with sound planning. Test your soil before making any amendments. Never guess application rates. Remember that the soil texture plays a role, since clay will require even more material than sand. Your patience guarantees you will maintain a stable pH for the seasons ahead.
