Frequently Asked Questions

Does Haywire™ False Cypress grow in zone 5a or only 5b and above?

  • Haywire™ False Cypress thrives in zones 5-7, which includes zone 5a. This cultivar was specifically bred for superior cold hardiness compared to other Port Orford cedar relatives. Plant with confidence in zone 5a locations.

How much sun does Haywire™ False Cypress need—full sun, part sun, or shade?

  • Haywire™ False Cypress thrives in full sun to partial sun conditions. This Proven Winners® selection needs at least 6 hours of direct sunlight daily to maintain its vibrant green color and dense pyramidal form. Shop at Nature Hills for this low-maintenance evergreen that's hardy in zones 5-7.

What are the planting instructions for Haywire™ False Cypress when it arrives?

  • Plant Haywire™ False Cypress in well-draining soil with full to partial sun exposure in zones 5-7. Dig a hole twice as wide as the root ball but no deeper, keeping the top of the root ball level with the surrounding soil. Space plants 12-18 feet apart for mature size or closer for screening.

Is Haywire™ False Cypress deer resistant?

  • Yes, Haywire™ False Cypress is deer resistant due to its aromatic foliage that deer typically avoid. The natural oils in the threadleaf foliage act as a deterrent while maintaining the plant's ornamental value. Plant it confidently in deer-prone areas for reliable evergreen screening.

Does Haywire™ False Cypress require pruning, and when?

  • Haywire™ False Cypress maintains its naturally symmetrical pyramidal shape with little to no pruning needed. Its moderate growth rate and excellent form eliminate the frequent shearing required by traditional hedges. If light shaping is desired, prune in late winter before new growth begins.

What fertilizer does Haywire™ False Cypress need?

  • Haywire™ False Cypress thrives with minimal fertilization once established. A balanced slow-release fertilizer applied in early spring provides adequate nutrition for healthy growth. Avoid over-fertilizing, which can compromise the natural form and cold hardiness in zones 5-7.

Is Haywire™ False Cypress salt tolerant for coastal areas?

  • Yes, Haywire™ False Cypress shows notable salt tolerance, making it well-suited for coastal properties and areas near winter-salted roads. This hardy evergreen thrives in zones 5-7 while maintaining its vibrant green color year-round. Plant it as a specimen or privacy screen in salt-prone locations.

How do I mulch and maintain even moisture for Haywire™ False Cypress?

  • Apply 2-3 inches of organic mulch around the base, keeping it 6 inches from the trunk. This established evergreen handles summer heat well once its roots are developed. Water deeply but infrequently during the first two growing seasons to encourage deep root growth.
