You generally
don't need to compress soil when planting perennials.
Here's why:
* Air is essential: Perennial roots need air to breathe and thrive. Compressing the soil makes it dense and limits air circulation, potentially suffocating the roots.
* Water drainage: Compacted soil hinders water drainage, which can lead to root rot.
* Root growth: Perennials have extensive root systems that need space to grow and explore for nutrients.
What to do instead:
* Gentle backfill: After planting, gently firm the soil around the base of the plant with your hands to ensure good contact.
* Mulch: Applying a layer of mulch around the plant helps retain moisture, regulate soil temperature, and prevent weed growth.
* Amend the soil: If your soil is naturally compacted, consider amending it with compost or other organic matter to improve drainage and aeration.
Exceptions:
There are some rare exceptions where compressing soil might be necessary:
* Slope planting: If you're planting on a slope, you might need to gently tamp the soil to prevent erosion.
* Sandy soil: Very sandy soil might benefit from slight compaction to retain moisture better. However, be careful not to overdo it.
In general, focus on creating a loose, well-drained soil environment that will allow your perennials to establish and flourish.
