Arizona Ash Tree
Known as velvet ash tree, Arizona Ash trees are popular landscaping trees in the southern part of the United States. They are famous for their dense foliage and beautiful blossom. They are perfect shading trees in hot summer providing dense shades for your house. They usually need very little maintenance during their growth, and only a few times of watering would be adequate if some mulching materials are applied on the base around their roots. You just need to do some pruning in winter to keep them tidy and healthy.
The Arizona ash trees are considered as medium-sized trees which can reach about 50 feet in height with a similar spread. They are able to resist most pests and diseases and just a few pests and fungi like Emerald Ash Borer can affect their health. They can bloom attractive flowers in the early spring when other trees just end their dormant period, making it a good option for decorating your spring garden. They prefer well-drained soil conditions with adequate sunlight during the day. Although they are tolerate drought environment well, you still need to water them at least once in sizzling summer days.
Unlike most fast growing trees which need frequent trimming to make them tidy, Arizona ash do not need a lot of pruning work unless some of their branches are seriously damaged. Since they can be infected by some fungi like anthracnose, some fungicide is required constantly, ideally twice per month. The most dangerous pests which can weaken the health of trees are the borers. A dursban spray can be applied to get those pests under control. You should apply the pesticide for a certain amount of time to effectively get rid of them. Abnormal colours on leaflets usually indicate the deficiency of water and nutrients in their body, and thus fertilizers and water should be applied as soon as possible. Generally, a fertilizer with a balanced recipe of 12-12-12 is adequate for their nutrition supplements.
