Mandevilla, Pink Allamanda 'Alice Dupont'

Bringing it in, I noticed fuzzy bits that squash when rubbed. Since I have a full-sun window, I am not doing the "winter dormant thing" as an experiment.

But I guess I need to get rid of these white fuzzy things.

Anybody had success with this situation? Thanks.

I bought a new plant every year for about 15 years before someone told me they could go dormant. Last year right before frost, I strippe...Read Mored off most of the leaves & put 2 of them in a mostly dark unheated basement (no colder than 40) along with my Brugmansias. I dumped a cup or so of water on each of them about once a month. The rest of the leaves fell off & they looked dead. In spring, I repotted them with new soil & they sprouted from the older vines & sent up new ones from the bottom. They look great & are blooming. I am going to try to keep them again this year.

I have had this plant for the 2nd year. Last year I planted the 1 gallon plant into a 12in pot. I had some mildew problem.

I brough the plant out starting in April, this is early for Atlanta and I needed to watch for colder nights. The plant gets only 4 hrs of sun from 11AM to 3PM and dappled PM sun. But it grows nicely, bug-free and started blooming in June. My placed a tropical hibiscus standard next to this plant and havn;t got a single bud on it so far.

I wedge large staples from the hardware store into the shale to attach the stems to the cliff. Once the vine establishes a good framework it is no longer necessary to do much attaching. They become spectacular specimens by mid summer and are covered with bloom till frost. I haven't made a serious attempt to over winter the plants but will try again this fall now that i have instructions from Dave's Garden. It is well worth the $29 they ask at Lowe's for good sized ones so I just buy several each year. They are not usually available here till early June. If I could get them in time to plant by May 15th I could have an earlier and larger display.

I also plant one Alice D. (pink) in a large pot beside a fire escape and it climbs to 25 feet and covers the entirerailing with gorgeous foliage and blooms.

Some one asked about the tubers. The plants make lots of them and it would seem they could be stored and used to start new plants in the spring. Has anyone tried this?

Now... no flowers, not a one, and wondering when they will re-appear. I live in San Diego, California and it sits on my patio with partial sun. Most of the time the bottom part is in the shade as my small patio fence is facing west and the plants pot is on the other side, but it does receive indirect morning sun and direct late afternoon sun on top portion. The soil is moist, but alas, the flowers aren't blooming and when trying I think, they are stopped before they develop.

It was still in full bioom and just breathtaking to look at. The root ball was out of the ground about an hour or so then I stuck it in the ground watered it in and went back to work. not thinking too much about it. Three or four days passed and the weather had gone from 70 to 40 and cold rain set in.

I found this site and just sat back and laughed when I foud it to be a zone 10 or 12 tropical, but in the cold rain I went out and potted the two of them up into big square patio pots. NOW 2 months later they have stopped blooming and are putting up with the warm dry heat I have been misting them 2 or 3 times a week. I really thought they were goners, all the flowers and most of the leaves browned and fell off but today I have new shoots coming up from the bottom out of the soil as well as new growth on the vines as well, wish me luck!
