|Background: I started Burpee Moonflowers indoors. They germinated well and started growing well. They had a slow start after transplanting to larger pots on my desk. I water them daily and they are growing very well. The vines are over 10 ft tall. I have them growing up twine against a south facing wall where they get sun early morning to late afternoon. It is now late July and I have no flowers. There are what look like flower buds at the joint of the leaf stalks and the vine. These buds are small no more than 1/2" in length. A few have dried up and fallen off. Others just seem to stay small. I used 10-10-10 fertilizer in the pots at planting and have added some liquid fertilizer on a weekly basis. I have tried to avoid too much fertilizer fearing I would stimulate too much vine growth and no flowers. Your package says to plant indoors for earlier blooms but does not say when to expect flowers.
Question: What can I do to encourage Moonflowers bloom?
|It sounds like you are doing all you can, with the possible exception that larger pots might help ( athought for next year). These vines are tropicals and seem to take a long time to come into bloom in our northern clime. Once they start, though, they keep on going into the fall. Full sun, keep them well watered to avoid stress, maybe try some "blossom booster" type fertilizer (any fertilizer with a high middle number, follow the label instructions). Note too that they open at night and close up in the morning. The wait is worth it!|
