I have high hopes for this clover in my backyard (which gets absolutely hammered by the sun in the summer)! It has sprouted & I have my finger's X'd that it fills in.
Thank you for the review, Kate! We’re so excited to hear that your microclover has sprouted and is off to a good start.
To help it fill in those areas that get hammered by the sun, make sure to keep it consistently watered through the establishment phase. Once it is fully established, you can then begin to reduce the frequency of watering. We have high hopes for your backyard as well!
