Temperature

Grown outdoors under natural conditions. Frost protection should not be necessary. 

 

Light

Chamaecyparis pisifera ‘Golden Mop’ grows best under a shade system (30%) that needs to be installed by WK14 and removed by WK37. 

 

Crop Timing

Plant 4” inputs into a 6” in WK6-12 for sales in WK38-15. 

 

Relative Humidity

During the hot summer months, transpiration will cease at relative humidity (RH) levels below 45% and above 90%. When RH drops below 45%, a short period of pulse irrigation in the morning lengthens the period of time for transpiration to take place. This results in prolonged uptake of vital nutrients for continued growth. 

 

Media

Chamaecyparis pisifera ‘Golden Mop’ must be grown in a medium with adequate air porosity. A minimum of 40% coarse peat moss should be incorporated into the soil mix. Media pH must be kept between 5.0- 5.5. A low rate of 8-9 month slow release fertilizer (18-6-12, for example) can be incorporated into the growing media.

 

Irrigation

Maintain an even watering schedule, especially through the heat of summer. Do not let them run dry, never go below a Level 3 on the soil moisture scale. Typically water first thing in the morning on hot days, and follow up with a watering early afternoon (if necessary) so that foliage has time to dry off going into the evening.

 

Fertility

Feed Chamaecyparis pisifera with a fertilizer containing medium levels of nitrogen after transplanting. Transition to lower nitrogen fertilizer  as roots start to fill the pot. Plants should be hardened off before any risk of frost. The target for EC in the soil is 0.5-1.0. 

 

Trim

If trimming is required, do not trim later than WK31. If you do, trimming wounds will still be visible at time of shipping. 
 

Space

Space plants to prevent foliage touching, allowing for adequate light to prevent stem elongation, and sufficient air movement to prevent disease.

 

Pest Management

Chamaecyparis must carefully be monitored for fungal diseases and insect pests. Common insect pests are aphids and leafrollers. Aphids and leafrollers decrease ornamental quality and vector diseases.
