Geranium in pot leaning
I am starting small with 1 geranium in a pot. It really gets battered in the wind. It has leaned to the side for the longest time. I propped it up a bit with some rocks and put it in a place where the wind wouldn't get to it as bad and it perked up a bit. But we had a bout of really nasty weather the past couple days, (while I was at work and couldn't get home ... it has been cold-around 45-70-and windy), and my geranium is back to leaning again.
Is this just the wind? Am I doing something wrong? Perhaps the little guy isn't strong enough and needs some more fertilizer? I have some slow release fertilizer mixed in with the pot but that is it. I water it about once a day if it hasn't rained. Is it not supported enough in its little pot?
Also, I have some browning of the leaves (see pic as well). Is this a sign of some kind of nutrient deficiency?
Help is appreciated!
