In this way, how fast does aucuba grow?
Aucuba grows slowly, taking 10 to 20 years to reach a mature height of 6 to 10 feet and spreading to cover a 4- to 6-feet diameter; under ideal conditions, it can reach more than 15 feet tall.
Similarly, you may ask, why is my aucuba turning black?
Cause. The blackening of the leaves is usually caused by root stress due to excess moisture levels in the soil during cold, wet winters. Other forms of stress, including root diseases (mainly phytophthora root rots) might also be involved.
Use tip cuttings to propagate crotons. A tip cuttings is a 3- to 6-inch branch tip taken from an actively growing croton bush. Use a pair of clean, sharp pruning shears when cutting branches for rooting and make the cuts at 45-degree angles. You can take and root croton branches any time during the growing season.
