The best time to stop fertilizing your flower garden depends on a few factors, but generally speaking, you should stop fertilizing
around 6-8 weeks before the first expected frost. Here's why:
* Encourage dormancy: Fertilizers can stimulate new growth, which is not ideal as the weather cools down. You want your plants to focus on storing energy for the winter, not growing new leaves or flowers.
* Risk of disease: New growth can be more susceptible to fungal diseases in cool, damp conditions.
* Nutrient overload: Too much fertilizer can actually harm your plants in the winter.
Here are some additional factors to consider:
* Your plant variety: Some plants, like bulbs, benefit from fall fertilization to help them prepare for the spring.
* Your climate: In mild climates, you may be able to fertilize later than in colder regions.
* Your fertilizer type: Slow-release fertilizers release nutrients gradually, so you may be able to use them a bit later in the season.
General Tips:
* Pay attention to your plants: If you notice your plants are still growing vigorously, you may need to stop fertilizing sooner.
* Don't fertilize after the first frost: This can encourage weak growth and make your plants more susceptible to damage.
* Clean up your garden: After you stop fertilizing, remove any dead leaves or debris to prevent diseases.
Remember, it's always best to check with your local garden center or extension office for specific recommendations based on your region and plant variety.
