About soil condition, Elaeagnus macrophylla prefers well-drained soils but is tolerant of a wide range of soils including heavy clay soils. It also tolerates salt and smog and can be used as a street tree.
So, like the other elaeagnus plants, elaeagnus macrophylla requires full sun to partial sun to grow properly. The plant should receive at least 6 hours of sunlight per day, but it can tolerate up to 8 hours of sunlight per day.
The temperature condition that is most ideal for Elaeagnus macrophylla is one that is relatively cool and not too hot. This plant is native to areas that have a moderate climate, so a temperature condition that is too extreme in either direction can be harmful to the plant. For example, if the temperature gets too hot, the leaves of the plant may begin to droop and the plant may stop growing as quickly. On the other hand, if the temperature gets too cold, the leaves may turn brown and the plant may become dormant.
Ideal humidity condition for this plant is between 40 to 60%. If the humidity drops below 40%, the leaves will start to drop. If the humidity exceeds 60%, the leaves will become soggy and start to rot.
The fertilizer, this kind of plant needs is one that is high in phosphorus. The roots of the elaeagnus macrophylla are very aggressive and can easily damage septic tanks, sewer lines, and patios if not kept in check. This shrub can grow up to 20 feet tall and just as wide, making it a very large and potentially dangerous plant if not properly maintained.
Pruning is an important part of keeping your elaeagnus macrophylla plant healthy and looking its best. You should prune your plant regularly to remove any dead or dying branches, to encourage new growth, and to shape the plant the way you want it to look. When pruning, be sure to use clean, sharp shears to make clean cuts.
Propagation of elaeagnus macrophylla is typically done through root or stem cuttings taken from the parent plant. Cuttings should be taken from new growth and should be 4-6 inches long. Cuttings can be taken from both the softwood and hardwood of the plant. The cuttings should be placed in water or moistened potting mix until they develop roots. Once roots have developed, the cuttings can be transplanted into individual pots.
Usually, the plant growth rate takes place during the spring and early summer. However, the plant may continue to grow and produce new leaves throughout the summer months. The average growth rate for this plant is between 3 and 5 inches per year.
Common problems for this kind of plant are powdery mildew and root rot. Powdery mildew is a fungus that appears as a white powder on the leaves and stems of the plant. Root rot is caused by a fungus that attacks the roots of the plant and prevents the plant from taking up water and nutrients. These problems can be controlled by treating the plant with a fungicide.
