Japanese falsecypress

For Japanese falsecypress (Chamaecyparis pisifera 'Kost Yellow'), water the soil evenly and deeply when the top few inches of soil have become completely dry. This may require watering anywhere from once a week to once every few weeks, depending on the amount of moisture, temperature, and humidity in the air. During times of heat or drought, water more frequently, as much as once a day.

For a species like the Japanese falsecypress (Chamaecyparis pisifera 'Kost Yellow'), the optimal amount of sunlight to provide is 5-6 hours of full sunlight per day. It thrives best in direct, bright sunlight in the morning and afternoon, while avoiding the strong midday heat. This will help keep its vibrant golden-yellow foliage and keep it healthy. In the winter months, it will be able to tolerate some shade and redirected sunlight, but during the warmer, sunny months it is best to ensure it has sufficient sunlight.

Prune Japanese falsecypress (Chamaecyparis pisifera 'Kost Yellow') in spring or late winter before any new growth. Prune to maintain shape and size, thinning out the ends of branches by 1/3 to 3/4, but never removing more than 1/3 of the total width of the shrub. Water, fertilizer, and an all-purpose tree protectant can be used to nourish and strengthen the shrub if necessary. Pruning should not be done too frequently, as it can weaken and reduce the potential health and beauty of the plant.
