The target soil pH to grow healthy conifers is slightly to moderately acidic at 5.5 but can range up to 6.0 and as low as 3.5 in the case of Fraser fir (Abies fraseri). Many plants do well in acidic, slightly acidic, neutral, near neutral soils, alkaline soils; in other words, they will grow fairly well in some to all ranges as long as they are not extreme. If you have acidic soil, you do not have to spend a fortune on changing it. A graduate of East Carolina University, Kilpatrick writes for national and regional publications.
