The irrigation water must be able to flow away unhindered and must not accumulate in the planter, for example. Otherwise rot can occur and the Dipladenia will no longer bloom and slowly die. It is enough to water them once a week.
How do Dipladenia cuttings best form roots?
To improve the rooting of dipladenia cuttings, they should be dipped in arooting powderorwillow water. In general, cuttings of Dipladenia, also known as Mandevilla, root rather poorly. It is therefore advisable to stimulate rooting when propagating through cuttings. It is also important to pay attention to the following points:
- Cut 10 cm long cuttings

To do this, take the root ball out of the pot, carefully remove the soil and cut off the root tips. The root ball can then be put back into the pot and filled with fresh soil.
Tip
Too much water reduces flowering
If the Dipladenia is watered too much and the roots are constantly exposed to moisture, they put their strength primarily into the shoots. This means that fewer flowers are produced. It therefore makes sense to water the Dipladenia sparingly and to allow the soil surface to dry.
