Question Hello-I have started a vegetable garden around the base of an old dead oak stump.The soil seemed wonderful and easy to till, sandy and loamy and initially all the vegetable plants seemed to do well but all are yellowing somewhat now.Is there a deficiency in oak soils?How can I correct it.Thanks
Answer Hi Pamela, the soil may be deficient, but it would have little to do with the oak. Oaks however, tend to grow in soil that's more acidic than your garden would prefer, so I'd have your pH checked. I suspect you'll need to add some lime. Your pH should be around 6.5. Yellowing can be caused by nutrient deficiency, water issues (too much or too little) and disease, so I'd take a soil sample and a few leaves to your local garden center and let them give you a more accurate diagnosis.
