Will my morning glory bloom if it is in partial shade?

Probably not. They really need full sun to produce flowers.

Can I prune the vines to help it flower?

Yes, light pruning can help redirect energy, but do not cut more than one third of the plant at once.

Morning Glory: not flowering, causes and fixes

Check these first

Check the fertilizer label for high nitrogen content.
Observe the plant for at least 6 hours to track direct sun exposure.
Look for tiny buds hiding under the dense foliage.

Likely causes

Excess Nitrogen
Most likely
How to tell: The plant looks very lush and leafy but has zero buds. This happens when you use a fertilizer meant for leafy greens instead of flowers.
What to do: Switch to a fertilizer with a low first number, like a 5 to 10 to 10 ratio. Stop all high nitrogen feeding immediately to force the plant to focus on reproduction.
Insufficient Light
Most likely
How to tell: The vines are stretching toward the light and the leaves look pale. Morning glories need at least 6 to 8 hours of direct sun to trigger blooming.
What to do: Move the container to a spot that gets full, unobstructed sun. If planted in the ground, prune back nearby branches that are casting shade.

When to worry

If the plant is healthy and growing fast but has no buds by mid summer, you need to change your care routine. It is normal for young plants to spend the first few weeks only growing vines.

Stopping it coming back

Use a bloom booster fertilizer from the start and ensure the plant is in the sunniest spot in your garden.
