Brussels Sprouts fertilizer schedule

Brussels Sprout plants are classified as heavy feeders due to their rapid vegetative growth. They need to fill soil nutrients frequently to fuel this growth. Feed them twice at least during the growing season. Feed with a high nitrogen fertilizer per month for excellent growth that contains boron. Plants need more boron saplings than other vegetables to prevent hollow stems and small buds. Brussels Sprouts also need more boron than other vegetables.

Boron is a plant nutrient that is used in fine quantities by all plants, without it, Brussels Sprouts produce hollow stems and small buds. If these symptoms have appeared in your plants, you can add boron to the soil by dissolving 1 level tablespoon of borax in 5 quarts of water and spraying it evenly on a 50 square feet bed. Don’t be tempted to mix too much, because it causes too many problems. Also, do not apply unless there are signs of deficiency in your plants that we have just mentioned.

Fertilize before planting and then mid-season, side-dress plants with well-aged compost, or even feed with organic fertilizers such as 5-10-10 or 10-10-10. Heavy rains or sandy soils, supplement the soil with nitrogen-rich manure. Sprinkle 1/2 cup of 21-0-0 fertilizer under each 10-foot row about 6 inches from the plant base. Water after fertilizer so that nutrients seep into the soil.

How to fertilize Brussels Sprouts in pots 

Brussels Sprouts are heavy feeders. You can add well-rotten manure when planting in potting mix and side-dress plants with compost or manure or with balanced fertilizer 3 to 4 weeks after transplanting. Then, when they are grown in half, apply fertilizers like 10-10-10 or 5-10-5 or 5-10-10 as per instructions on the product. Alternatively, you can also feed this vegetable crop with a liquid fertilizer every other week instead of time-based. These plants prefer nitrogen-rich soil. You can side-dress organic fertilizers such as compost or manure.

The manure mixed in water also works well. If you have transplanted the plant into a large vessel, wait 3 weeks after the transplant. Fertilization is not always necessary. If you modify the soil with fertilizer before planting, there must be a lot of nutrients to support the plant as it grows. It said many gardeners like to add fertilizer to help Brussels Sprouts further. While plants are like nitrogen, they can be very harmful. Excess levels of nitrogen will result in more foliage.
