The Best Way to Plant Rhubarb: A Comprehensive Guide

Rhubarb (Rheum rhabarbarum) is a hardy perennial that can thrive in various conditions, provided it gets the right care during planting and growing seasons. This guide will walk you through the best practices for successful rhubarb cultivation, from choosing the right variety to establishing a healthy base for your plants.

Understanding Rhubarb's Needs

Rhubarb requires a cold winter to thrive, as it is well known for its preference for cooler climates. This plant needs a period of dormancy, which usually occurs during the winter months, to prepare for growth in the spring.

Planting Rhubarb from Crown or Seeds

The most common method of growing rhubarb is from crown, which is a piece of the plant’s stem. Buying a crown from a reputable supplier is an easy and effective way to ensure you are starting with a healthy and productive plant. However, if you are passionate about breeder material, you can also plant rhubarb seeds:

Seeds: Plant rhubarb seeds in soil water and wait for germination. It's a slow process, but with patience, you can grow rhubarb from seeds.

Crown: Choose a healthy crown of a known variety. This is easier and quicker, as the plant will establish itself faster and produce earlier.

Establishing Your Rhubarb Patch

Choose a spot in your garden that receives full sun, ideally in the range of USDA hardiness zone 6 and higher. Ensuring that your planting area gets ample sunlight is crucial for the health and productivity of your rhubarb. If you live in a region with hot summers, make sure to provide some protection from the hot afternoon sun, as this can stress the plant.

Rhubarb prefers rich, well-drained soil that remains lightly moist. Ensure that your soil has adequate organic matter such as compost or dried manure mixed in. This will help provide the necessary nutrients and moisture retention to support healthy growth.

Planting Techniques

Begin by digging a hole large enough to accommodate the rhubarb crown or seeds. If using a crown, place it in the ground with the knob (the top end) of the crown below the ground level. Surround the plant with a layer of rotted manure and ensure it receives a good amount of sunlight.

Water your newly planted rhubarb well. The first year, consistent watering is essential to help the plant establish a strong root system. Once established, watering can be reduced slightly, but it should still receive about once a week during dry periods.

Additional Care Tips

In spring, apply manure around the base of the plant. This will provide the necessary nutrients for healthy growth. Regularly check for issues like root rot, which can be a concern in poorly drained areas. Rhubarb is generally hardy, but it is important to monitor the plant’s health and address any issues promptly.

Over time, your rhubarb plant will become more robust and may even spread naturally. However, over time, it can become less productive, and it is advisable to divide and replant the rhubarb every 3-4 years to maintain its vigor.

With the right care, rhubarb can be a rewarding addition to your garden. Whether you are planting from crown or seeds, following these guidelines will help you establish a flourishing rhubarb garden. Enjoy the fruits (and leaves) of your labor!
