Why Are My Acorn Squash Seedlings So Tall?

Acorn squash matures faster than most winter squash varieties.

Healthy transplants are important because they decrease the chance of shock and increase the plants ability to mature quickly. Sometimes transplants become too tall, leggy or spindly. This leads to damage of the stem, damping off and stunted growth.

Sunlight

Transplants are usually started in the winter or early spring when there is less sunlight, so it is common for seedlings to reach for more light. This makes the plants top heavy with weak stems. If your plants are leggy and are not exposed to sun most of the day, then consider moving them to a location with more light. If a better location is not possible, use grow lights to compensate.

Nitrogen

Excessive nitrogen can lead to large heavy leaves and weak stems. Soil mix for transplants should be on the mild side. If you add fertilizer, dilute it. This helps seedlings grow strong roots and stems.

Considerations

If your acorn squash seedlings, or any transplants, look too tall and it is warm enough to plant them, the best option is to get them into the ground. If it is still too cold for transplanting, then consider direct sowing acorn squash as soon as it is warm enough. Acorn squash ripens early in most climates.
