Fisher Space Pens are also something to look into as well for a low-cost âtactical pen.â You canât beat the ability to write in water, heat, cold, upside down and in 0 gravity environments, since most of you reading this commonly travel into space. Iâm joking of course, I really do like Space Pens.
A lemon tree normally goes through three periods of fruit drop. The first drop occurs when 70 to 80 percent of the flowers fall from the tree without ever setting fruit. A week or so later, pea-sized fruit drop from the tree. The third drop occurs in spring when the fruit is about the size of a golf ball. Unless premature fruit drop is excessive, however, these drops are not a cause for concern. In many cases, lemon tree fruit drop is due to environmental factors that you canât control. Sudden changes in temperature and heavy rains can often cause premature fruit drop.
Most often, leaves on pear trees turn black due to fire blight, a highly contagious bacterial infection. The culprit is the bacterium Erwinia amylovora. This disease not only attacks pear trees, but it endangers apple and crabapple trees as well. Fire blight is identified early on by spots on the trees with bark that oozes a light tan material. This ooze leads to streaked bark. If left untended, the bacteria first infects open flowers and young fruit, which turn black. Eventually the leaves turn black and die as well.
