watering

The Sulphur Flower (Eriogonum umbellatum) should be watered once per week if planted in a pot, using 2-3 gallons of water. If planted in the ground, it will need a deep watering once a month, preferably during the morning hours or during dry spells. Avoid wetting the leaves when watering, and avoid frequent, shallow watering as this can easily cause root rot. During hotter weather, water twice per week for plants in pots; for plants in the ground, increase the water to once per week.

sunlight

The sulphur flower (Eriogonum umbellatum) prefers full sun and should be grown in areas that receive at least 6–8 hours of direct sunlight per day to maintain the deepest yellow color and flower display. When given ample sun, this species will produce its best flower display. It also benefits from at least some light shade during the hottest part of the day where temperatures exceed 90°F (32°C).

pruning

For Eriogonum umbellatum, a moderate amount of pruning should be conducted in late spring or early summer. Pruning too much may cause the plant to produce fewer flowers the following season. To prune the plant, simply remove the faded flowers and generally trim the plant’s stems back by 1/3. It is also important to note that if the plant has become leggy, then it should only be cut back by half of its height.
