Environmental stress such as temperature fluctuations can cause cole crops including cauliflower and broccoli to bolt. “Bolting” refers to premature flowering and negatively affects the taste. Ensure cool season vegetables are receiving consistent moisture, especially with the heat and wind we’ve experienced lately. One-inch of water per week is typically enough for these crops. You can test the moisture of the soil by inserting your finger to a depth of one inc Continue fertilizing every two to three weeks until harvest. Fertilizer can be applied on the soil surface next to the rows of plants. This technique is called “side dressing”. Use a high nitrogen source of fertilizer such as blood meal. Lawn fertilizers could be used but cut the rate in half. Do not use lawn fertilizers that include weed killers or preventers.
