- little
- Amount
- ≈ 0.2 lb
- Next feeding
- None needed
For a 32 sq ft bed, that's roughly 0.2 lb (3 oz) of fertilizer, spread evenly and worked into the top 6 inches a few days before planting. A soil test beats any rule of thumb — if you have one, follow it instead.
- Lush vines with few pods = too much nitrogen. Peas want lean soil.

Why
And that's the whole season — peas fix their own nitrogen — routine sidedressing does more harm than good.
- One balanced pre-plant application plus a fruit-set sidedress matches how demand actually rises.
- Peas are legumes — they fix their own nitrogen, and extra fertilizer grows vines at the expense of pods.
When this doesn't apply
- Soil test results override this: high-P soils need nitrogen-only products.
- Beds heavily amended with compost each year may need only half this rate.
