When general advice is not enough
Some gardens need a proper conversation
The advice pages on this site cover the most common questions Irish gardeners ask. But every garden is different and some situations are more involved than any single page can address properly.
If you have read through the advice here and still feel uncertain about what your garden needs, or if you are about to make a significant decision about planting, redesign or investment, an online consultation is the right next step.
We work through your specific situation together and you leave with a clear direction rather than a general answer.
