Jasmines plants (Jasminum) either grow as a shrub or a vine. They prefer a spot in full sun or partial shade and during the summer, the soil and plant can dry out quickly. Most varieties have fragrant flowers that bloom in the spring or summer months. The most familiar varieties include Confederate jasmine, common white jasmine and winter jasmine. Even though there are many jasmine plant varieties, they have similar watering needs.
Water your jasmines with an inch of water just after planting. Water at the base of the plant and do it slowly so the water can soak into the soil rather than run off.
Water jasmine plants in the summer when hot temperatures and the sun can quickly dry them out. According to the Ohio State University, this is especially beneficial for jasmines in their first year, but still is necessary in subsequent years even though they are established.
Water jasmine plants with about an inch of water whenever the soil dries out until it is wet to about 1 to 2 inches deep. Spread the watering out about 8 to 12 inches from the base of the plants to allow the water to sink down to the spreading roots.
Cover 8 to 12 inches around the jasmine bases with 2 to 3 inches of mulch in order help prevent water evaporation. An organic mulch, such as wood chips, is best since it will decompose over time and add essential nutrients to the soil. Replenish the mulch when it decomposes.
