ball moss<\/p><\/div>\n
Ball moss is not really a moss, but an epiphyte or air plant, meaning it’s roots are exposed to the air.\u00a0 It is in the bromeliad family, and so is related to pineapples, believe it or not.\u00a0 While the majority of experts believe it is not harmful, because it is believed to receive its nutrition entirely through air and rain, some arborists including me believe that in large quantities ball moss definitely has a negative impact on trees.\u00a0 This is due to its shading out buds and young leaves.\u00a0 There is definitely a major impact when we have ice storms, as the greatly increased surface area causes much more breakage on limbs coated with ball moss.<\/p>\n
There are really only two ways to deal with ball moss.\u00a0 Manually remove it, or spray it with chemicals.\u00a0 Manual removal is the far superior technique, as it can be extremely thorough and can address any pruning needs at the same time, while eliminating the side effects of chemical use.\u00a0 However, it is far more expensive, usually more than five times the cost. Another problem with manual removal is that the average tree service’s unskilled climbers often remove too much foliage or damage a lot of the tree bark when removing ball moss.<\/p>\n
Spraying is usually accomplished with one of three chemicals.\u00a0 Baking soda is one of them, and while it sounds benign, its high salt content and pH can be harmful to soils.\u00a0 It is also not nearly as effective as copper hydroxide.\u00a0 This chemical can be harmful to young foliage and is toxic to aquatic life however.\u00a0 A third salt, potassium bicarb, while extremely effective, is extremely expensive, and actually not labeled for this use.\u00a0 Unfortunately, none of these chemicals will kill more than about 70% of the moss, usually killing only about half, and the moss remains on the tree for months or even years until it finally rots off.\u00a0 With manual removal, it is gone instantly.<\/p>\n
Mistletoe is undoubtedly a parasitic plant and harmful to trees.\u00a0 Its root system (haustoria) is in the wood of the tree, drawing water and some nutrients from it.\u00a0 It can also cause a weakness of the tree branch it is attached to.\u00a0 In these ways, mistletoe causes significant problems for trees and should be removed annually.\u00a0 There really is no spray option for mistletoe.\u00a0 While there is a spray on the market, it only defoliates the parasite; it doesn’t actually eradicate it.\u00a0 And it can wreak havoc on understory plants.\u00a0 So manual removal is the only practical option here.\u00a0 Unfortunately, complete removal is not possible once the mistletoe is severely entrenched in larger tree limbs.\u00a0 Smaller limbs that are infected should be completely removed.<\/p>\n
