Q.Sweet peas
My sweet pea plant is starting to get yellow leaves on the bottom part of the plant and lots of pods all of a sudden. Overwatering? Am I supposed to be doing something for the plant to be fuller? Do I want pods? Thanks.

Yellow leaves can happen for a number of reasons. If leaves turn yellow suddenly, as opposed to yellowing slowly over time, the #1 cause in too little moisture in the soil. Try watering more, or more often.
