Cover crops for shaded compacted lawn

Date Posted: Mon, Sep 16 - 12:32 am
- Hello! I have a very compacted front lawn that only grows Japanese clover (and just barely). It’s in full shade below large willow oaks. A shovel only gets a couple inches deep, and that’s after jumping on it a few times. I have a dream of planting groundcovers like Chrysogonum, Fragaria, and Ajuga, but I don’t think they’ll do well in compaction. Are there any cover crops I can plant to overwinter that will help with this? I was thinking daikon, but don’t know if they’ll do well without sun. Any tips for combatting this compaction would be very helpful!
- So many of us know this struggle with compacted soil!. Daikon radish is often recommended for breaking up compacted soil due to its deep taproot. However, it does require at least partial sun to grow well, and in deep shade, it may struggle. I'm curious when the leaves typically fall from your willow oaks as that should help the area get more sunlight. You might consider crimson clover or white clover which can tolerate low light levels better and also help improve soil structure by fixing nitrogen. Personally, I would be inclined to seed with both diakon radish and clover. If both end up growing that should be a huge help to your soil! Other ideas to consider include applying a layer of compost or leaf mulch. This will encourage earthworm activity and other soil organisms that naturally aerate the soil over time. If physically possible, aerating the lawn with a manual or mechanical aerator can make a big difference. This opens up the soil, allowing water and nutrients to penetrate more effectively, and provides a better environment for your planned groundcovers. And once the soil has improved, your choices of Chrysogonum, Fragaria, and Ajuga could thrive better. These are excellent for shaded areas once the compaction is reduced. Good luck! We'd love to hear what you decide to go with and the outcome that you get.
