It is better to grow brassicas when cooler weather arrives. With shorter days, crisp mornings, and the approach of fall rains, conditions are ideal for establishing leafy greens such as kale, arugula, broccoli, and cabbage. Success, however, depends on timing, soil preparation, and careful planting.
Start Indoors or Direct Seed Outdoors
Many growers begin brassicas indoors four to six weeks before transplanting them outside. This method ensures seedlings are strong enough to handle shifting temperatures. At the same time, many brassicas—especially fast growers like arugula and kale—can be sown directly outdoors. Combining both approaches allows for staggered planting and a continuous harvest throughout the season.
Build Rich, Moisture-Holding Soil
Brassicas demand fertile soil capable of holding moisture without becoming waterlogged. Mixing compost, manure, or organic matter into topsoil creates a fluffy, nutrient-rich base. These big-leafed plants absorb abundant sunlight and require steady access to water. Beds should be watered deeply before planting and kept consistently moist during germination and early growth.
Plant Shallow, Water Often
One of the most common mistakes is planting brassica seeds too deep. The seeds are tiny, almost like grains of sand. A light scratch of the soil, followed by sprinkling seeds and gently covering them, is all that’s needed. Watering frequently is crucial to trigger germination and sustain growth. Maintaining moisture, especially during dry spells, ensures strong and healthy plants.
Extend Your Harvest
By starting seeds indoors, planting directly outside, and staggering crops, growers can maintain a steady flow of leafy greens throughout the season. With well-prepared soil, proper planting depth, and consistent watering, brassicas will flourish in fall conditions and deliver nutrient-dense harvests week after week.
