About Brazilian Jasmine

Mandevilla sanderi · also called Brazilian Jasmine, Dipladenia · flowering

Brazilian jasmine, often sold as dipladenia, is a tender tropical plant with a bushier, more trailing habit than climbing mandevillas. It bears glossy leaves and showy trumpet flowers in pink, red or white throughout summer, ideal for pots, baskets and patios. Heat- and drought-tolerant once established, it must be overwintered frost-free in cool climates.

Mature size: Typically 0.5-1.5 m (1.5-5 ft) tall and wide as a mounding/trailing plant in containers

Watch for — Root rot from overwatering: Its top cause of decline; soggy mix rots the roots and yellows leaves. Use a gritty, free-draining mix, let the surface dry between waterings, and never leave it sitting in water.

How to tell brazilian jasmine needs repotting

Repotting on a calendar is less reliable than reading the plant. For brazilian jasmine, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot brazilian jasmine

Every 2–3 years, into bone-dry mix. Brazilian Jasmine's growth habit — bushy, mounding to trailing tender perennial, more compact than climbing mandevillas and well suited to pots and hanging baskets; can be lightly trained on a small support. glossy leaves and red, pink or white trumpet flowers all summer. milky latex sap exudes from cut stems. trim to keep tidy and free-flowering. — sets the pace.

What size pot to step brazilian jasmine up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Brazilian Jasmine stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot brazilian jasmine

Spring or summer, while brazilian jasmine is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting brazilian jasmine

Repot dry. Do not water brazilian jasmine for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty well-drained, gritty potting mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set brazilian jasmine at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep brazilian jasmine completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for brazilian jasmine

Brazilian Jasmine wants well-drained, gritty potting mix. Use a free-draining mix with added perlite, grit or sand; slightly acidic to neutral pH. Sharp drainage is essential, as this plant is prone to root rot in heavy or waterlogged soil. Moderate organic matter supports its long flowering. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting brazilian jasmine — frequently asked questions

How often should you repot brazilian jasmine?

Every 2–3 years, into bone-dry mix for brazilian jasmine. Repot brazilian jasmine every 2–3 years into a snug pot of well-drained, gritty potting mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does brazilian jasmine need?

When is the best time of year to repot brazilian jasmine?

Should you water brazilian jasmine after repotting?

No — not straight away. Repot brazilian jasmine into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise brazilian jasmine after repotting?

Not immediately. Wait about 3 weeks after repotting brazilian jasmine. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
