Planting pine trees may seem straightforward, as their needle-like leaves resemble those of cacti, which should have excellent water retention. However, during the planting process, it's observed that when water is lacking, the needle leaves can drop significantly. For slightly larger trees, failing to supplement them with nutrient solutions is simply not an option. In summer, the flow of sap within the pine tree increases, and the pine oil also becomes more active. Attempting to hang nutrient solutions can lead to clogs, and without the necessary nutrients and moisture, the trees struggle. So, what can be done?

Actually, the solution is simple.

Planting pine trees has become quite popular because they remain green year-round and don't shed their leaves like most broadleaf trees, which drop their leaves in the fall and winter, leaving bare trunks. They are commonly seen in parks and residential areas, and many families also have various ornamental plantings. However, pine trees grow slowly, with a gradual rooting and sprouting process. Yet, they still lose significant moisture during the summer. If nutrient solutions aren't supplemented, the pine needles may drop, and in severe cases, this can lead to the tree's death. When administering the solution, it's easy for the pine oil to clog the injection point, making it difficult to continue. Some bags may remain unused for ten days to two weeks because the holes have likely healed, causing even slower flow.

To prevent the pine oil from clogging the nutrient solution injection points, you can create slightly deeper holes for the needles, ensuring the needle tip doesn't go all the way in but leaves some distance for flow. Additionally, you can hang the bag higher to increase the pressure of the nutrient solution, or simply use a wider needle, which is less likely to clog.
