There are a couple ways you can "plant seeds" today:

1. The Word of God is considered a "seed" in some Bible references. Plant Scripture in your mind and heart today so that it can grow and produce fruit.
2. Evangelists and Missionaries "plant seeds" of the power of Christ to people around them. You can plant seeds by telling strangers about who God is and how much He loves us all. You can also practice the art of "giving it all to God", meaning when somebody compliments you just tell them that it is God doing the good things and you're just thankful to God.
