Do I need to fertilize to get flowers?

Peas generally do not need much fertilizer. Too much nitrogen can actually cause the plant to grow leaves instead of flowers.

Will they flower in the shade?

No, snow peas require full sun to produce a good harvest. Shade will result in weak plants that fail to bloom.

Why are my snow peas not flowering? Causes and fixes

Check these first

Measure the hours of direct sunlight the plant receives.
Check the local temperature forecast.
Inspect the plant for aphid infestations.

Likely causes

Excessive heat
Most likely
How to tell: The plant looks healthy but refuses to set buds as temperatures climb. Snow peas stop producing flowers when the air temperature stays consistently above 80 degrees.
What to do: Plant your peas earlier in the season to avoid the summer heat. Use heat tolerant varieties if you live in a warmer climate.
Insufficient light
Most likely
How to tell: The plant is growing slowly and has very few or no flower buds. Snow peas need at least 6 to 8 hours of direct sunlight every day to bloom.
What to do: Move the container to a sunnier spot if possible. If they are in the ground, prune back nearby plants that might be casting shade.

When to worry

If the plant is mature and the weather is cool but no buds appear, it may be a nutrient issue. It is normal for very young plants to have no flowers.

Stopping it coming back

Ensure your peas get full sun and are planted during the correct season for your local climate.
