FERTILIZING
If you are growing plants in a container or pot then the soil is always maintained. The reason being, if not done so, it will become compacted and lead to root rot which would eventually kill your plant regardless of how well cared for it was beforehand. One way this problem can be solved is by using high-quality potting mix that does not need any extra fertilizer as too much might disrupt its natural growth pattern towards leafy foliage instead of blooms! The type of fertilizer needed by your plants depends on the variety that is growing in the container. In fact, when it comes to application timing, too will be different according to which hydrangeas plant you have!
If you want to grow big leaves, applying light fertilizer in March, May and June will make that happen. Oak leaf hydrangeas do well with two applications of fertilizers in April and June while panicle varieties require only one application a month.
You may be growing a smooth hydrangeas variety and need to apply fertilizer in late winter.
