Watch out for

Aphids: Squash infestations by hand or spray with a strong jet of water; use insecticidal soap for severe cases.

Powdery mildew: Improve air circulation, avoid overhead watering, and apply a fungicide if the infection is severe.

Slugs and snails: Use physical barriers like copper tape or eggshells, or apply slug pellets sparingly around the base.

Cucumber mosaic virus: Remove and destroy infected plants immediately to prevent spread; control aphid populations.

Heat stress: Provide afternoon shade in hot areas and cut back severely to encourage fresh growth when cool.
