Early June marks the peak season for rhubarb, with its stalks reaching their most succulent and plump state. However, gardeners are urged to closely monitor the plant’s crown in the coming weeks to ensure a successful harvest. As temperatures rise, rhubarb is at risk of bolting, a stress response that causes the plant to stop producing edible crops and focus on seed dissemination instead.
When bolting occurs, rhubarb ceases to yield edible produce and begins to sprout slender, woody flowers that significantly weaken the plant. To prevent this, Kimberly Killebrew, an experienced gardener and creator of Daring Gourmet, recommends a straightforward solution: promptly removing any seeding pods before they mature and propagate.
Killebrew advises, “Ideally, you want to prevent your rhubarb plant from reaching the stage where it develops flower stalks. These long shoots initially appear as seed pods at the base of the plant. As soon as you notice them, remove them.”
According to the Express, these seed pods initially emerge as tender green shoots encircling the rhubarb’s crown, where the stalks typically sprout. These shoots may have red or pink striations and resemble a cabbage head or a clenched fist.
Fortunately, these seeding pods are quite delicate and can be easily removed if identified quickly. When spotted, simply use a knife or gardening shears to cut them off as close to the plant’s base as possible.
If flower clusters are observed, it is crucial to remove them immediately. Although they can be stubborn, ensuring that your garden shears are sharp and effective is essential. By removing the flowers and pods, the rhubarb plant can redirect its energy towards producing the largest and most succulent stalks in time for a June harvest.
Killebrew further advises, “With the seed pods and flower stalks removed, your rhubarb plant can now focus its energy on producing a delicious and healthy yield of edible rhubarb stalks. Continue to check your plant frequently for new seed pods and remove them promptly.”
It is important to note that rhubarb typically starts bolting when stressed by hot weather. Regular watering is crucial to prevent the soil from drying out. Mulching the rhubarb or placing it in a shaded area, especially if it is potted, can also help keep the plant cool and protect the crop.
However, the most effective strategy for preserving rhubarb stalks is to inspect the plant daily. Early removal of budding flowers greatly increases the chances of successful growth and a bountiful harvest.
