If you ever see a weird orange gummy bear-like thing growing on your juniper, you likely have apple trees nearby and apple rust. The first time I saw this I had no idea what I was dealing with!Cedar-apple rust is a common plant disease caused by the fungal pathogen Gymnosporangium juniperi-virginianae. It infects members of the Rosaceae and Cupressaceae families, primarily apple, crabapple, eastern redcedar, and other juniper species. Cedar-apple rust is a widespread disease across the continental U.S. and is a common issue for apple producers due to…

 Indoor: If possible, these trees will benefit significantly from summer outdoors. Ideally, they should have all been moved out by now, but there is still time if you have not already moved them out—water as needed. Watering will depend on the weather, the location of the trees (sunny or shady), the soil, the pot size, and other factors. In many cases, however, daily watering will be needed. Always check the moisture content of the soil before watering. Fertilization should continue. Check wires for tightness. Repotting may be done at…

Outdoor: Place trees in a maximum sunlight location. Make certain to water as often as needed. As the weather warms, the trees will need to be watered more frequently, often daily. Be sure to provide enough water at each watering to thoroughly saturate the soil. Fertilize regularly to keep the trees growing and to support the new growth. Pinch new growth as needed to increase the fullness of the foliage pads. Wire as needed, but be careful when working around the soft new growth as it is easily damaged.…

Outdoor: All outdoor trees should have been removed from winter protection and placed on their growing benches. The trees should be receiving as much sun as possible. Watering needs will be high, and all trees will need watering at least once daily. Be sure to saturate the soil thoroughly during each watering session.  It is good to send a blast of water through the foliage now and then to help dislodge any insects lurking. Keep an eye out for possible insect infestations. The soft new growth on the trees…

photo by Larry Magee Arakawa Rough Bark Maple 粗皮 Katlin Mulligan The Rough bark Japanese maple, Acer palmatum‘Arakawa,’ is a beautiful cultivar that exhibits rough bark, which adds impact to a bonsai. The rough bark is interesting and creates a focal point to the total aesthetic impact the bonsai presents. But, this cultivar does not present a quiet refined image characteristic of Japanese maples with beautiful bark which becomes gray when mature. Fine twigs are difficult to develop and a coarse feeling is usually presented. True Rough bark Japanese maples, Acer palmatum ‘Arakawa,’ must be…
