PlantFiles is getting a new look! Just in time for spring, we're rolling out a new look for the best online plants database. It will also work with your smart phones and mobile devices, so now you can take it with you on garden center visits or botanical garden tours. Questions or comments? Please post them here.
I have grown moss rose in the past and noticed that sometimes it blooms more than other times. What I can't figure out is why. Is it the temperature? Does it need a certain fertilizer/nutrient? Is it getting too much water or not enough? I have experimented around, and will often get lots of the long round leaves and the stems get long and healthy looking, but not many flowers. Then other times/years they bloom like crazy and are gorgeous. Anybody know what the problem could be?
This is one of those years where the plants look really good, but they aren't blooming much.
In my experience, they like heat and not too much water or fertilizer. Too much fertilizer for plants that can grow just fine in poor soil will often result in lots of lush green growth but not many flowers so if you've been giving them too much TLC that could limit the blooms. Or, I don't know what your weather's been like this spring but for this year at least it could just be they haven't got going yet--when I've grown them they've bloomed more in the summer vs the spring so it might just be a little early for them to be at their best. Sun will also be important--if they have too much shade they won't bloom as well.
Okay, maybe I need to move the potted ones to a sunnier location. The sun seems so intense though, (I didn't want them to burn up) but maybe full sun would be better during the spring (then give them a little shade only if they need it as the summer heats up.) It gets really hot here (last summer we were over 100 F for months at a time and it only got down in the 90's at night.)
And I'll skip them when I fertilize.
Thank you for the input ecrane3 - will sure be keeping it in mind since we want them happy and blooming! .
Mine always did best in blazing sun and heat also. I have them usually in clay containers sitting on a concrete sidewalk in full sun. I water sparingly in the morning as I head off to work. When the weather is cool or rainy they tend to slack off. The great thing about them for me is how they tell you when they are ready for water as they are succulents and start to look a little limp and wilty when they need more water.
