Alkaline soil - Bonsai soil having a ph rating over 7.0.
Apex - The topmost part of the tree, also called the crown.
Balanced - Fertilizers that provide equal parts of the three primary nutrients - nitrogen, phosphorus, and potassium.
Chlorosis can occur on very alkaline soils, though otherwise its pH tolerance is quite high. As concerns levels of moisture, the red maple grows everywhere from dry ridges and southwest facing slopes to peat bogs and swamps.
Acid and alkaline soils are not a problem for it. It can tolerate hot, dry weather and also hot and cold winds. It grows slowly, but strong; and can achieve great age, as it can resprout from its trunk, even if you cut or burn it.
Yellow leaves are a sign of an alkaline soil and an acid-based feed should help green up the foliage. Aphids can occasionally be a problem. The main pests to be aware of are scale insects, particularly around flowering time.
Pests and Diseases: Magnolias are relatively disease free, yellow leaves are a sign of an alkaline soil, an acid-based feed should help green up the foliage. Aphids can occasionally be a problem .
Can tolerate acidic or alkaline soils. Prefers a well drained acidic growing medium. Use 1 part peat moss or sphagnum moss, 1 part loam and 1 sharp sand. Alternatively use 1 part Akadama and 1 part Pumice.
Ok, so, firstly we'll start with the understanding that the yew is quite different to a juniper, but, share the ability to live in dry, alkaline soil in large sun exposure areas.
