What Are the Best Tips for Planting Brassica Seeds?

The various species of plants in the Brassica genus, which are types of mustards or cabbages, are relatively hardy and easy to grow. In order to successfully grow Brassica seeds, it is extremely important to plant them in well-drained soil. They do well in a variety of soil types and can tolerate a range of light levels. The seeds should be planted after the last frost and should be kept free of weeds.

Though Brassica will grow in any type of soil, it does best when planted in soil that has the proper balance of nutrients. Brassica seeds prefer soil that is rich in humus and nitrogen, which can be added to soil by mixing in manure or compost. Fertilizing the soil can cause the pH to drop, which can damage young plants or seeds, so it is best to complete the fertilization at least a couple of months before planting the seeds. Adding fish or meat and bones to the soil can also add additional nutrients that will greatly benefit the Brassica seeds.

The nutritional needs of plants in the Brassica genus are relatively high, so it is important to plant the seeds far enough away from each other that they do not have to compete too fiercely for space and resources. A distance of 6 to 8 inches (15 to 20 cm) between rows is usually adequate. Brassica should only be planted at a depth of about a half inch (1.3 cm) so that the plants can sprout and begin photosynthesis quickly. Once the Brassica seeds have sprouted, the plants should be thinned out, selecting the strongest plants and ensuring that these plants get enough nutrition.

Weeds also need to be kept away from Brassica seeds and seedlings. These undesirable plants can easily take nutrients and space away from young Brassica plants, which may fail to thrive in the presence of competing plants. Weedicides or nets that obstruct the growth of weeds can be used to keep weeds away.

Brassica seeds can be planted in areas of full or partial sun. They require a considerable amount of water and can die if the soil dries out. Seeds planted in sunnier areas require more water than those in partial shade. Temperature is also a concern. Though the plants can survive a frost, the seeds and seedlings can be killed if temperatures are too cold and should be planted after there is no chance of a freeze.
