Transplanting a Mandevilla Vine

I recently purchased a mandevilla vine and need to know if I need to transplant it to a larger pot. It is crimson and beautiful, so I want to make sure it does well. Thanks.

If it is blooming, you may want to hold off on repotting until flowering has stopped, as this could interfere with the blooms. If the plant seems to be rootbound, is difficult to water or the pot is simply too small, then move it up another couple sizes (or 2 inches in diameter).

If it's in a container, water at least once a day and 2 times a day in temps over 85 F. Those grown in the ground can be given a deep watering on a weekly basis, around 1-2 inches.

Yes, mandevilla can be propagated by seeds, cuttings, or dividing the root-ball; however, most new plants are produced from softwood cuttings taken in early spring. Here is more information: http://www.gardeningknowhow.com/ornamental/vines/mandevilla/mandevilla-propagation.htm

Are Mandevilla Plants Poisonous to Dogs and Cats

Are Mandevilla plants poisonous to dogs and cats?

ANSWERS

It is considered in the list of poisonous plants, but allegedly its toxicity is very low, and no severe symptoms would result from ingesting it. However, to be on the safe side, I would try to keep the plant away from them, though these animals normally won't bother the vine. Here are articles with toxic plants for cats and dogs that may be helpful to you as well: http://www.gardeningknowhow.com/plant-problems/environmental/plants-toxic-to-cats.htm

Mandevilla Vine

I have a mandevilla vine that has been growing beautifully, bit all of a sudden leaves turning yellow and falling off.

ANSWERS

There are a number of reasons why the leaves may turn yellow. One might be overwatering. Too much water causes yellowing of the leaves and mandevilla do not like overly wet feet. Another possibility could be too little water. If this is the case, the yellow leaves would be curling up as well. Mealy bugs can occasionally affect these plants, causing them to become weak and leading to yellow foliage. Finally, plant stress due to a change in location, temp., etc. can lead to yellow leaves. Mandevilla favor humid conditions. If your plant is exposed to the sun, the soil may be too hot. Try misting/spraying the leaves with water in the mornings and keep the soil moist (NOT wet). You may also want to consider moving your plant (if possible) to an area that doesn't receive direct sunlight for extended periods of time.

Troubleshooting Mandevilla Problems

My daughter gave me a gorgeous mandevilla plant growing on a two ft. high trellis. It was beautiful and after a month leaves turned spotty yellow and green and dried up and started dropping off. The plant now looks dead. Is it or is it dormant?

Mandevilla Not Flowering

It had a few blooms when I bought it, but none since I transplanted it to a larger pot.

ANSWERS

It is likely just the stress from repotting and should right itself once it recovers. However, to help it along some, you can try giving the plant some phosphorus rich fertilizer or add some bone meal to the soil.
