Follow-Up From Herald Article- Plants Speak to Us
Hello Donna, I enjoyed your Saturday August 06 (Calgary Herald) article about plant nutrient uptake. PLEEEEZe tell us how we can correct these problems in your next week's column. Kt
Ah Kate- - fixing the problem depends on what causes the problem- for instance Magnesium deficiency (shown on the tomato leaf above) is sometimes caused by low pH - which can be caused by the potting soil being acidic or it can be caused by lack of magnesium. The latter can be fixed just by adding the micronutrient -using a product such as Kelp. The low pH can be a bigger problem because if the soil was not balanced before you bought it that is a problem. Don't buy that soil again or fix it now by adding lime. So you have to rule out one problem and then look for the solution. If you simply add Mg and the pH is low it may not be available to the plant.
Iron "deficiency" is also more of a pH problem and once that is changed through using more compost and making sure the soil is watered well but not waterlogged, the problem can solve itself. I will try to add more bits and pieces in my Blog but am also trying to write a book right now so am torn with these writing projects! Thanks for your feedback... ps - I only write in the Herald every second week so check back her for more updates.
