Caliente Rojo Mustard Blend Seeds | Biofumigant Cover Crop | Root Knot Nematode Suppression | 100 Square Feet
Brassica juncea
Listing is for 1 packet with enough seeds to cover crop a 100SF area
Caliente Rojo Mustard Blend is a specialized biofumigant cover crop developed specifically to improve soil health while helping suppress soil-borne pests and diseases. Unlike standard mustard varieties, Caliente Rojo was selected for its exceptionally high levels of glucosinolates — naturally occurring sulfur-containing compounds found within mustard plant tissues. When the plants are chopped and incorporated into moist soil, these compounds break down and release biologically active substances similar to naturally occurring fumigants. This process can help reduce populations of root knot nematodes, certain soil-borne fungal pathogens, and other harmful organisms that can build up in intensively cultivated vegetable gardens. For gardeners struggling with root knot nematodes, Caliente Rojo offers one of the most effective biological tools available, especially when combined with crop rotation and healthy soil management practices.
Beyond its biofumigant properties, Caliente Rojo is also an outstanding soil-building cover crop. It grows rapidly, creating a dense canopy that shades out weeds while producing abundant biomass that improves soil structure and organic matter levels. Its vigorous root system helps improve soil tilth while supporting beneficial microbial activity. This is a cool season cover crop - so its best to use during the fall or spring, or if your in a mild winter area with no snow, it can be used as a winter cover crop. Each packet contains enough seed to cover crop a 100 square foot area. Simply sow directly into prepared soil during cooler growing periods (fall, winter, and spring), allow the plants to reach peak vegetative growth, then chop and incorporate them into the soil while still green. Thriving in full sun and moderate temperatures, Caliente Rojo is an excellent choice for gardeners looking to rehabilitate vegetable beds, suppress root knot nematodes naturally, and build healthier, more productive soil for future crops.
BONUS TIP: Before broadcasting your seeds, soak them for a few minutes in compost tea or compost extract. This coats the seeds with beneficial microorganisms that go straight into your soil at planting. These good microbes naturally compete with and suppress root knot nematodes — and paired with the Sorghum Sudangrass's own nematode-fighting root activity, you're giving problem soil a serious one-two punch with almost zero extra effort.
PLANTING
Germination: 5-10 days
Seed Sowing Depth: Broadcast over the soil surface and gently rake them into the top 1 inch of soil
Sowing: Direct sowing only. Caliente Rojo is a mustard blend, which is a cool season crop. This cover crop is best used during the fall or spring. If your in a mild winter climate, as in no snow areas, can also use this as a winter cover crop. For cover cropping during the summer, I recommend Sunn Hemp or Sorghum Sudangrass.
When & How to Terminate This Cover Crop (No Tractor Needed): Allow this cover crop to grow for 6-10 weeks. The leaves should still be small, and the main stem should be thin, tender, as in has not hardened up and got woody. It is hard to cut this down without machinery if allowed to grow tall, or go near the start of flowering because the stems start to get hard. This timing is critical because glucosinolate levels are generally highest during vigorous vegetative growth and before the plant directs significant energy toward flowering and seed production. For maximum biofumigation benefits, cut the plants down while they are still lush and green using hedge shears, a string trimmer, weed trimmer, or garden sickle. Immediately chop the material into smaller pieces to rupture as many plant cells as possible. Next, incorporate the chopped material into the top 4 to 6 inches of moist soil using a weeding or stirrup hoe (my preference), garden fork, broadfork, shovel, or tiller. Water the area thoroughly after incorporation to activate the biofumigation process. If your goal is primarily soil improvement rather than nematode suppression, you may also leave the chopped material on the surface as a mulch layer or allow it to decompose naturally. In raised beds and containers, the process is simple: cut the plants down with hand pruners, chop the foliage into smaller pieces, and mix it into the growing medium. Wait approximately 2 to 3 weeks after incorporation before planting vegetables to allow decomposition and biofumigation to complete. This waiting period helps prevent potential seedling stress while maximizing the soil-health benefits of the cover crop. ***For soil biofumigation*** The biomass must be tilled/mixed into the soil so it can release compounds into the soil that supress root knot nematodes and other pests.
