What To Know
- The amount of fertilizer you use will depend on the type of fertilizer, the age of your plants, and the soil conditions.
- As the plants start to flower and produce fruit, switch to a fertilizer with a higher phosphorus and potassium content (like 10-20-20).
- By following these guidelines and understanding the nuances of how to fertilize squash, you can ensure your plants thrive and reward you with a plentiful harvest.
Growing squash plants can be a rewarding experience, offering a bountiful harvest of delicious and versatile fruits. But to ensure your squash thrives and produces an abundance of plump, juicy fruits, you need to provide it with the right nutrients. This is where understanding how to fertilize squash comes into play.
Understanding Squash Nutritional Needs
Squash plants are heavy feeders, requiring a consistent supply of nutrients to support their vigorous growth and fruit production. They particularly need nitrogen (N) for lush foliage, phosphorus (P) for root development and flowering, and potassium (K) for overall plant health and fruit production.
Choosing the Right Fertilizer
There are several types of fertilizers available for squash, each with its own advantages and disadvantages. Here’s a breakdown of the most common options:
- Granular Fertilizers: These are easy to apply and release nutrients gradually over time. They are ideal for a slow and steady release of nutrients.
- Liquid Fertilizers: Liquid fertilizers are readily absorbed by plants and offer a quick boost of nutrients. They are particularly helpful during periods of rapid growth.
- Organic Fertilizers: These fertilizers are derived from natural sources like compost, manure, and bone meal. They provide a slow and steady release of nutrients and improve soil health.
When to Fertilize Squash
The best time to fertilize your squash plants is during the growing season, starting when they are about 6 weeks old. You can continue fertilizing every 2-3 weeks until the fruits start to develop.
How Much Fertilizer to Use
The amount of fertilizer you use will depend on the type of fertilizer, the age of your plants, and the soil conditions. Always follow the instructions on the fertilizer packaging.
General Guidelines:
- Starting Fertilizers: Use a balanced fertilizer with a ratio of 10-10-10 or 5-10-5 at planting.
- Growing Season: Use a fertilizer with a higher nitrogen content (like 20-10-10) during the early stages of growth to promote foliage development. As the plants start to flower and produce fruit, switch to a fertilizer with a higher phosphorus and potassium content (like 10-20-20).
Fertilization Techniques
1. Side-Dressing: This involves applying fertilizer along the sides of the plants, about 6 inches away from the stems. This technique helps to prevent fertilizer burn and allows the roots to easily access the nutrients.
2. Foliar Feeding: This method involves spraying a liquid fertilizer directly onto the leaves of the plants. This allows for quick absorption of nutrients and can be particularly helpful during periods of stress or nutrient deficiency.
3. Granular Application: This involves scattering granular fertilizer around the base of the plants, then lightly working it into the soil. This technique is best used early in the growing season.
Common Squash Fertilizer Mistakes to Avoid
1. Over-Fertilizing: Too much fertilizer can burn the roots and damage your plants. Always follow the instructions on the fertilizer packaging and avoid applying more than recommended.
2. Using the Wrong Type of Fertilizer: Using a fertilizer with an incorrect nutrient ratio can lead to nutrient deficiencies or imbalances.
3. Fertilizing Too Close to the Stem: This can burn the roots and damage the plants.

Quick Answers to Your FAQs
1. Can I use compost to fertilize my squash?
Absolutely! Compost is an excellent source of nutrients and improves soil health. You can add a layer of compost around your squash plants every few weeks.
2. My squash plants have yellowing leaves. What’s wrong?
Yellowing leaves can indicate a nutrient deficiency, often a lack of nitrogen. Try applying a nitrogen-rich fertilizer to see if it helps.
3. How often should I water my squash plants?
Squash plants need consistent moisture, especially during hot weather. Water them deeply every 2-3 days, making sure the soil is moist but not soggy.
4. Can I use coffee grounds to fertilize my squash?
Coffee grounds are slightly acidic and can actually inhibit the growth of some plants, including squash. It’s best to use other organic fertilizers.
5. What can I do to prevent squash vine borers?
Squash vine borers are a common pest that can damage squash plants. You can use row covers to protect your plants or manually remove any borers you find.
