Either affected by Mandevilla (Dipladenia sanderi) diesease or overwatering (details below) According to fmscare. Com1, dipladenia is also known as Mandevilla or Brazilian Jasmine. Based on my research on the net there are several things might cause the leaves turning brown.It might might be affected by disease 2 or might be due to overwatering.

Below are snippet of similar problems and solutions3. Hope this help! ***Snippet from velvetmandevilla.

Com on the disease of MandevillaDiseases of MandevillaThe following diseases occur on Mandevilla. They usually occur during the warm and wet months of the summer. The diseases can spread rapidly when leaves are left wet overnight.

Use an approved fungicide, such as Zyban as soon as spots are present. These diseases can spread to other plants quickly. Leaves will turn yellow with spots and fall off the plant after a few days.

Removal of infected leaves and spraying with a fungicide and careful watering will stop the disease from spreading to other plants or to other leaves on the same plant. Cercospera has been more of a problem than Corynespora.1. Corynespora Cassiicola on Mandevilla 2.

Cercospera Leaf Spot on Mandevilla 3. Cercospera Leaf Spot on small plants***Snippet from hortchat.comQ. I just got a mandevilla this summer and I put it inside last month.

First it was pretty and healthy but now its leaves are getting brown by the ends and then got brown spots and then drop. I want to know if it is a fungus or I am overwatering. I water it every week and I leave some water in the botton of the plant.A.

Keep your Mandevilla on the dry side and do not leave any standing water, it will invite problems like root rot. It will drop leaves with cooler temperatures, dry air and less light. You can let the plant go dormant by triming it, giving it minimal water (from which it will drop all its leaves) and keeping it in a cool place (basement, cellar).

It will regrow in all its glory next spring. Q. Need advice, I sucessfully winterized my 2 mandavilla’s thru the winter by bringing indoors and cutting back, the plant grew lovely new green leaves an lots of new shoots, this week, May 6 I put the plant back outside for only 1 day, watered and fertilized, and only 1 day later the leaves are turning brown.

Is it maybe because the temp went down to about 42 degrees last night. Would that be the reason or should I have not fertilized yet? Should I bring it back inside until warmer, can I save my plant?

Toronto, CanadaA. The temperature can do that. Wait till night temps are 50 degrees.

Also your plant needs to be eased to the outdoors in a shaded area, for a few hours a day increasing each day. It’s been indoors for a long time in much lower light exposure . Too much sun will scorch your new leaves, give them time to toughen up.

You can trim back the brown areas and it will regrow even bushier.Q. My Mandavilla’s vine is growing well, but the mature leaves on the plant are browning and dying from the leave’s vein outward to the leave’s edges. I wouldn’t call it “yellowing” as I’ve seen in over-watering of other plants, but a dry, dying brown leaf.

Is this not enough water? The plant is planted in the ground in a good sunny spot. I don’t want to lose my new Mandevilla - it’s beautiful!A.

The mature leaves that are browning can be going through an aging process and dying back. As long as the exterior new foliage is growing, I don’t think there is anything to worry about.Q. I also have mandevillas that are turning brown and dying.

I have already lost two this summer and two more that are dying. The leaves turn brown mostly on the tips and outer edges first then move to the whole leaf. Some of the flower buds also turn brown.

They also have long shoots with no leaves or flowers. They have done well in past years.A. If the weather has been hot in your area brown edges on the leaves can be caused by hot,dry air, or sun scorch.

In additon browning leaves can be an indicator of underwatering especially if the mandevillas are growing in a container. Hot weather will require watering for as much 3 times a week to to keep the plant from drying out . Be sure to water enough and let the water drain out-don’t allow your plant to sit in water or you will have other problems (root rot).

You may also want to give it a dose of fertilizer (8-12-12) to boost it up for the upcoming winter. Brown leaves can also be pest or disease related. ***1 http://fmscare.com/index.php?plant_care&page=7&s=t&key=2 http://www.velvetmandevilla.com/diseases_of_mandevilla.htm3 http://hortchat.com/info/mandevilla-care-and-tips Sources: link inside .

I had this problem this year for the first time. Check for Aphids under the leaves. Noticed wasps and flies on the plant.

They were eating the aphids. Sprayed and the plant returned to health.

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.
