Cynanchum acutum Care
Cynanchum acutum
A native vine that, as its name (Bostanbozan) suggests, spreads quickly in agricultural and garden areas and can be invasive. It is very drought tolerant; it is generally not grown intentionally, and its control and management are important.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Fertilizing: Absolutely not needed.
- Pruning: All dry stems above the soil can be cut and destroyed.
- General care: To prevent its spread, digging out the root system when the soil is workable is the most effective method.
- Pests & diseases: It is dormant.
- Frost risk: Its underground roots are very hardy.
- General care: Last chances to lift the roots.
- Pests & diseases: It is dormant.
- Pruning: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering.
- General care: Constant checking and clearing of new shoots drains the plant's energy.
- Pests & diseases: New shoots begin to emerge.
- Pruning: Keep cutting the shoots off at the base continuously.
- Plant protection: A systemic herbicide (e.g. Glyphosate) application is most effective when the shoots are 15-20 cm (apply it if you consider the plant a pest, and take great care not to splash it onto other plants).
- General care: Do not let the shoots wrap around other plants.
- Pests & diseases: Growth is very fast.
- Pruning: Continuous pruning and checking is the most important task.
- Plant protection: Herbicide application can be repeated if needed.
- General care: It can smother the plants it climbs on; clearing it is important.
- Pests & diseases: Aphids may be seen but generally do not harm the plant.
- Watering: In a long drought, water deeply once a month.
- Pruning: Cutting the shoots before they flower prevents spread by seed.
- General care: If not kept in check, it spreads over a very large area this month.
- Pests & diseases: Usually very healthy.
- Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. The area around the roots should be wetted to a depth of 20-30 cm.
- Pruning: Continue checking.
- General care: It continues to grow even in the hottest and driest months.
- Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. The area around the roots should be wetted to a depth of 20-30 cm.
- Pruning: Cut off and discard the flowers and any seed capsules.
- General care: Do not lose control of it.
- Watering: In a long drought, water deeply once a month.
- Pruning: It must be pruned before seed capsules form.
- General care: Seed capsules spread quickly by dispersing their cottony seeds on the wind, so it is critical to prevent their formation.
- Pests & diseases: Spread by seed is the biggest risk.
- Pruning: As the plant begins to yellow, all above-ground parts can be cut and burned or discarded.
- General care: With the autumn rains, the soil may become workable again for lifting the roots.
- Pests & diseases: The plant prepares for winter dormancy.
- Pruning: Remove dead branches.
- General care: Work on lifting the roots can continue.
- Pests & diseases: It is dormant.
- General care: If the soil is not frozen, root control can continue.
