In addition to watering the rhubarb, you can make it grow better by adding commercial fertilizer, compost, or rotted manure.
Here are a few tips to help your Rhubarb grow well:
Watering rhubarb keeps the soil around the plant moist for maximum nutrient uptake.
However, the soil surface does not have to be extremely wet.
Rhubarb plants need at least 4 inches of soil around the plant to stay moist.
So dig about 4 inches around the plant and examine most of the contents.
If the soil is very dry, you should water it.

When watering rhubarb, focus on the base of the plant.
Avoid watering the leaves as this could encourage pests and diseases.
The best time to water rhubarb is early morning.
You can also add mulch around the plant to lock in moisture in the soil.
The afternoon sun helps evaporate water from the foliage that could attract pests.
