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!

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…

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…

Outdoor:           This is the busiest month in bonsai.Once the danger of temperatures in the low twenties or less has passed, it is time to bring your trees out of winter protection and into their summer homes. For trees in mulch beds, be sure that the mulch has thawed below the pots before lifting the trees out of it. Do not force trees from a frozen mulch bed, as significant damage can result.Watering requirements will increase, so be prepared to water more frequently. Fertilization can begin…
