How to Grow Rhubarb Safely
Choosing the Right Location for Rhubarb
Rhubarb prefers a cool and temperate climate, so choosing the right location is crucial. Plant your rhubarb in a spot that provides full sunlight in the morning hours, but avoid areas that get too hot during the day or have stagnant water.
You should also avoid planting rhubarb near trees and other plants as they can compete for nutrients and water.
Soil Preparation and Fertilization
Prepare your soil by digging it deep, about 12-18 inches, and adding compost or aged manure to enrich it with organic matter. Do this process weeks before planting so that the soil has time to settle.
Add fertilizer after planting as needed. A balanced fertilizer with an NPK ratio of 10-10-10 will provide enough nitrogen, phosphorus, and potassium for healthy growth.
Watering and Pest Management
- Rhubarb needs moist soil but not wet feet
- It is crucial to establish a regular watering schedule when you plant your rhubarb. Inconsistent watering can lead to root rot diseases
- Pest management includes watching out for slugs as they can cause significant damage during growth season
- A natural way of controlling pests on rhubarb is companion planting — grow herbs such as mint around the plant bed which repels critters like aphids naturally
Harvesting and Storing Rhubarb
Your rhubarbs are ready for harvest when its stalks reach at least 10 inches long. Harvest by gently pulling off from the base of each stem closest to the ground.
