Yellow leaves often indicate that as does over watering tho, careful adding to much nitrogen, peas naturally put out excess. I have found if I harvest peas constantly the plants last longer. But as soon as one pod goes past the point of eating and goes to seed the plant starts to die. But I have only had this issue with snap peas this season so far. I added 2 tablespoons of molasses to a pitcher if water...waited to water so the peas were thirsty and would give them the molasses watering evey other week. Seemed to really extend my harvest.
Is it only yellowing from the bottom up? If so it is a sign of N diff, your Dads right and they will appreciate the ferts to munch on![]()
I believe overwater yellow is from the top down or all over. Are the leaves striped? If so, could be a Mag def too. I came across a Mag deficiency last year (lost the plant before I had the answer-easy fix too usually)
We used the fertiluzer sparingly so hopefully we don't give excess. They are yellowing from the bottom up, and until they start yellowing they are lovely and vining like crazy! We water only if the soil is dry, and not at all if rain is called for since afternoon showers are common here in central Florida. We also potted one so we can see if too much sun is hurting them. Fingers crossed this helps!
