Controls for Blossom Drop
by: Clark

When blossoms emerge but don't set fruit and fall off this is known as "blossom drop". It happens because the blossoms are not being fertilized.

Two typical causes for blossom drop are hot, dry spells or cold, rainy periods. Large fruit varieties seem to have the worst problem with blossom drop.

Since you're in Houston we can probably rule out the cold weather! To help prevent blossom drop you can investigate these ideas:

1) Keep plants mulched and well-watered.
2) Don't overfeed with nitrogen fertilizers that encourage green growth at the expense of fruiting.
3) Spray blossoms with blossom-set hormones.
4) Check for other disease symptoms that can also cause blossom drop.
5) Shake or vibrate the blossom stems with an electric toothbrush to encourage pollination.
