What to Plant in September

As the heat of summer fades and the winds of fall begin to blow quietly, September provides an ideal opportunity for your garden to embrace the change of seasons. This transitional month is ideal for planting a variety of cool-season vegetables, herbs, and flowers, preparing your garden for the fall and winter ahead. Find out what crops you can plant in September to extend your growing season and make the most of fall's potential.

If you're located in a warm climate zone, September is a good month to plant some heat-tolerant or late-season crops such as spinach, lettuce, carrots, and some root vegetables. These crops can be grown in the fall and harvested in the winter or early spring.

However, if you are in a cold climate zone, the weather gets progressively colder in September, which may limit the growth of some crops. It is recommended to sow fast-growing fall crops such as spinach and winter vegetables. There is also the option of raising seedlings indoors ahead of time and transplanting them when outdoor temperatures are suitable.

Indoor Seedling Trays vs. Direct Sowing in Raised Beds

Indoor seedling trays provide a controlled environment that helps with germination and initial growth, especially as the weather cools. This method allows growth to begin in a warm environment, avoiding the effects of cold temperatures outside on the seedlings. When choosing seedling trays, the top recommendation is a silicone seed starting trays that is durable, easy to clean, and reduces root damage.

Of course, for some hardy crops such as spinach, kale, carrots, and beets, direct sowing in raised garden beds can be more convenient. Installing raised bed covers can provide double protection for fall planting.

Why Choose Silicone Seedling Trays Over Plastic

First, choosing silicone seedling trays over plastic ones is crucial because silicone is a more environmentally friendly material. Derived from natural minerals, silicone has a significantly lower environmental impact during production compared to plastic, which typically comes from petroleum.

Additionally, silicone decomposes faster in the natural environment, posing less harm to ecosystems. Furthermore, silicone seedling trays usually outlast plastic ones. They offer better tear resistance and deformation resilience, maintaining their integrity despite exposure to sunlight, temperature fluctuations, or repeated use.

What's more, Vegega's silicone seed starting trays, made from food-grade material, contain no harmful chemicals like BPA. Moreover, silicone seedling trays are highly flexible, allowing easy removal of seedlings without damaging their root systems, which is vital for transplanting. Additionally, silicone resists dirt and bacteria, making it easy to clean.
