Winterize Mandevilla There are many varieties of Mandevillas,including varieties formerly known as Dipladenia. The old fashioned variety Mandevilla x amabilis Alice du Pont has fuzzy foliage and bright pink flowers, grows vigorously. Among other cultivars Mandevilla splendens (Dipladenia splendens) has a dark glossy leaf.

Both are grown trellised and have a tendency to vine. These species of tropical vines winter over only in the tropical South. They tolerate a minimum temperature of 45-50F at which time growth will begin to slow down.

For winter storage keep the plant outside as long as possible before bringing it indoors. Check for insects and use insecticidal soap if needed. To winterize the plant; either treat it as a houseplant or store it in a dormant stage.

Mandevilla as a houseplant can be trimmed back to make it manageable and needs a sunny window to flourish. Water once a week. You will get some leaf drop due to lower light and humidy indoors.

Another way to winterize mandevilla is in a dormant stage in a garage or cool basement with temperatures around 45-55F. Cut it back to about 12 inches above the soil line. Treat for insects if any.

Keep it dry but not completely dry. Check periodically for soil moisture. It will drop its leaves.

The important thing to keep in mind is that you want to keep it alive it through the winter. In the spring some of the old growth may be pruned back and when new shoots develop move the plant to a sunny window. Pinch the new growth to get a bushier plant.

Repot in fresh soil and set outside when danger of frost has passed. Sources: http://hortchat.com/info/winterize-mandevilla/comment-page-1 .

Yes, you can according to an expert, read more details at en.allexperts.com. Yes, you can treat it like it is summer as long as you are giving it longer days than nights with your light system. You have 2 fairly easy options for getting rid of the black spot.

The first would be to spray it lightly with aerosol Lysol spray every 3-4 days making sure you get the fronts and backs of all the leaves. Continue this spraying until the black spots are gone. Option 2 is mix baking soda in water and put that in a spray bottle and spray your diplandia with that.

Again, making sure you get the fronts and backs of all the leaves. Continue this spraying until the black spots are gone. The baking soda treatment is being used on roses to get rid of black spot and has been found to be very successful.

The only drawback is it leaves a white haze over the plant. I have used the Lysol spray several times on houseplants very successfully. Yes, you can water it normally and give it fertilizer.

If you keep it a bit cooler than usuall it is more likely to become healthier faster. Good luck. Sources: http://en.allexperts.com/q/House-Plants-721/dipladenia-indoors-during-winter.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
