Fertilising a Geranium macrorrhizum 'Ingwersen's Variety'
To ensure this species thrives and displays its vibrant summer blooms, a balanced approach to fertilization is key. It is recommended to fertilize in early spring, just as the new growth begins, using a general-purpose garden fertilizer. A second application can be made after the first flush of flowers has faded, usually in late summer, to promote continued foliage vigor and prepare the plant for its autumnal foliage color transition.
The resilient nature of the plant, coupled with its ability to adapt to a range of soil types, means that an excessive amount of fertilizer is unnecessary and could potentially harm the natural growth balance. Therefore, moderate use of fertilizer will suffice to support its growth and flowering needs without compromising its health or the environment it adorns.
