The water needs of the
Large yellow loosestrife can change depending on growth stages as well. For example, when your
Large yellow loosestrife is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your
Large yellow loosestrife will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your
Large yellow loosestrife will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your
Large yellow loosestrife more water at this time.
