How long does it take to start from seed.

My mandevilla has these long thick stems. Is this where the flowers bloom from.

My mandivilla flowers are being eaten. The leaves are healthy looking. But the flowers have circular spots that look like something is eating it. Need oil hasn’t helped, The marks appear overnight and are visibly worse every morning. How to treat?

I have 2 in hanging baskets that I left out during winter. We had a very hard freeze for 4-5 days. These beauties are blooming like crazy. I am going to plant them in the ground, if only I can decide the perfect spot. Good Luck

What are you feeding it with? What formula?

No it is not a perennial in your climate. Yes. It will die. It is a tropical plant. 45 degrees is the lowest it can take (and it won’t be happy about it). If you can cut it back a bit, dig a decent root ball, pot it up and put it in a sunny window it will be much bigger for you next year than buying a new small plant. I put mine in a tall planter, rather than round, where it had plenty of room for roots to grow down. It was was more than twice the size the next summer.

My mandeville has not blossomed in 2 years very healthy lots of foliage lots if vines kept inside all winter put in deck during summer but no blossoms i do notice some very small blackish seeds that come and go any suggestions? I do fedd regularly shoukd i prune it?

I found on another site hardy only to zone 9…I was also confused, hope this helps you…happy gardening!
