Mandevilla Red Care Guide
Light : High
Place in full to part sun to keep the plant blooming and to maintain their growth.
Water : High
This plant likes to be kept moist in well draining soil all blooming season.
Humidity : High
Requires high humidity.
Temp : 65℉ - 75℉
Add this plant to the patio garden when temperatures remain aboe 50°F in a sunny spot for 4-8 hours. If blooms aren't prolific, move to a sunnier spot.
Zone : 10|11
Outside: Keep them in full to part sun on a patio during summer months. Use them as an annual where nights dip below 50°F.
Fertilizer : Monthly
Fertilize monthly during their growing period (spring and summer months) with a balanced liquid fertilizer. Stop fertilizing during the fall and winter months while the plant is in their dormant phase.
Repotting : 2 Years
Water your plant a couple of days before transplanting. After receiving the Mandevilla, let them acclimate to their new environment for a couple of weeks before transplanting. Use a 2 inches bigger pot for a patio. Place a piece of screening at the bottom of the container over the drainage hole to secure the soil and allow to drain. Use a well-draining indoor potting mix with perlite to help with drainage. Add soil to the bottom to elevate the root ball. Lift the plant and release the roots against the existing planter. Use a clean knife or garden trowel to wedge between the grower pot and the soil to loosen. Inspect the root ball. Notice if there are any dead or rotting roots and trim them off with sterile pruners. If the plant is rootbound, loosen the roots to alleviate continued encircling. Ensure the plant is sitting about 1 inch below the edge of the pot to avoid water spillage. Add more soil and backfill around the sides by tamping down. Fill up to the soil line but not over. Water thoroughly, leaving the soil damp but not soggy. If settling occurs, add more soil. Water well to dampen the soil and let drain. Place them in full to part sun (4-8 hours).
The shoots on this plant can grow up to 3 feet. To manage the growth, trim back to a third in early spring after the last frost to give them a kick start. Your dipladenia vine is best enjoyed from a hanging basket.
Propagation : Cuttings
To propagate this plant during the growing season: Take a stem cutting in the early spring. Use a knife or sharp pruners, cut below a node where there are at least two to three leaves. Remove the bottom leaves to expose the node. Place the stem in rooting hormone and plant in moistened potting soil mix. Keep the soil consistently moist. Keep the cuttings in bright light. Add a clear plastic bag over the cutting and mist inside to raise the humidity level. Once the cutting has rooted after six weeks, the cover can be removed.
