That a beautiful photo of the area around.
Sadly if you bought this tree from one of the locations that sell bonsai to the general but not a bonsai nursery the tree is probably five needle pine. This is easily tree feller forge by counting the number or needles in a bundle joined together at the base.
If the needles are five, guess what it is a five needle pine and probably Japanese White Pine. Whether this"partial dropping" is normal depends on the tree species. Many species of conifers discard needles after years (for example Weymouth pine - Pinus strobus, Scots pine - Pinus sylvestris, Spruce - Picea), but some only much later. For example Black pines bonsai (Pinus nigra) lose their needles after years). Jan 24, You have to be really carefull about watering any plant, let alone a beloved bonsai.
It is very easy to fall into the 'death by kindness' mentality by watering more and more often if the plants are showing stress. Leaves shrivel or needles drop and we think 'needs more water'. The roots on most plants need to breathe. Dec 11, Needles must be nice and green. Some 3 year old needles will fall. A lot of needles on this tree look dull and will get brown and will fall off. Where they fall, the branch is dead. Look at the buds at the end.
Some are big and have a nice colour. Others haven't formed. You see the results of the conditions of the last 6 months. Heat stress is most bushlopping.barted Reading Time: 9 mins.
Dec 07, If your pine tree has browning or falling needles, you first need to identify the cause in order to help treat the issue. In an indoor pine tree, brown needles are typically a result of a lack of humidity or too low of a temperature. For an outdoor pine tree, browning needles are usually a sign of either waterlogged roots or a drought.
