Question

the ideal time of the year to cleft graft is ______. a. in winter, when the plants are dormant b. in spring, when new growth is young and tender c. late summer, when buds are mature d. early spring, just before the buds start to swell

Explanation:

Cleft grafting is a horticultural technique. The ideal time for cleft grafting is early spring, just before the buds start to swell. This is because the plant is coming out of dormancy, and the cambium is active but not yet in full growth, which helps in successful graft union formation. Winter (dormant) is not ideal as activity is low, spring new growth tender is for other grafts, late summer buds mature is not typical for cleft grafting.

Answer:

d. early spring, just before the buds start to swell
