| I live in zone 5 and purchased one of your Tango Twirl Mandevilla plants the third week in May. It is now the first week in July. I gave the plant a week to acclimate, leaving it on my back porch, before planting it in my garden. I planted it in the container, in the ground. It is growing nicely up the trellis,looks very healthy and has many buds on it. The problem is, the buds have stayed the same size for more than three weeks but not even one of them has opened. Is this a common thing? Is there something I can do to force the buds to open? |
| Based on your description (and a peek at the past month's weather for Syracuse) I suspect the cold nights may be delaying the blooms. Mandevilla is a true heat loving plant and objects to temperatures below fifty five degrees, it also needs warm soil temperatures to perform its best. Now that nights are staying in the 60's I would expect them to open. Also, be sure you keep fertilizing regularly with a water soluble or slow release fertilizer with an analysis of 5-10-5 or similar proportions. Finally, be sure to keep the soil evenly moist (damp, not sopping wet) for best results. Enjoy your mandevilla! |
