They are a little bother but I put a bucket over the plant and then the wall of water. Then I fill the tubes with a hose with a small stream or sometimes use a 2 gallon watering can with warm water from the house. When the W of W is full I remove the bucket and grasp the top of the wall and pull up a little. One person can do it but if a second person is available it helps. I've done it many times myself. An added benefit is the wall keeps the moisture in the soil so they don't require frequent watering. Great for root growth.
