Alpine Bitter Cress

Russian Pea Shrub (Caragana frutex) should be watered about twice a week. Watering should be done early in the morning to avoid evaporation and scorching from the sun. Providing enough water so that the soil is slightly damp is the best way to keep the plant healthy. During the summer months, once per week should be sufficient. During the winter months, when the temperature is colder, water less frequently. When the plant looks wilted or when the soil is dry, then water the plant.

Russian Pea Shrub (Caragana frutex) requires at least 4-6 hours of direct sunlight per day to grow and thrive. For optimal growth, it should receive full sun in the morning and then be protected from the strong afternoon sun. It does not do well in shade or in areas that get too little sunlight. When the temperatures are hot, it needs to be protected from the afternoon sun to prevent damage to its foliage and flowers.

Russian pea shrubs should be pruned in spring between late April and early June, when it is young and actively growing. They should be cut back by 1-third their size with lopping sheers or loppers, and any dead or weak branches should be cut away. Pruning should be done to encourage bushy growth, and all the stems should be cut to the same height. When pruning, it is important to leave a few of the main branches intact to help support the shrub. Too much pruning may leave the shrub vulnerable, so it is essential to only prune what is necessary.
