compost for nitrogen. any grass, broken and dead branches. Anything that used to be green or brown, can be used. get a box like a Rubbermaid container and drill holes in it. the sides and the bottom. then put all of your grass clippings, dead or dying foliage. It takes a while for compost to be ready. around 3 months oh and you got to keep it wet and take a rake and stir it up at least every three days or so. But in your case, you don't have that time to wait, so go to your nearest nusery or Walmart. they have it. bags of compost. or compost tea, it works faster. Its just water ran through compost and collected. spray on foliage and in soil. your plants will thank you for it.
Iron is one of those micro nutes that is usually found in soil. First thing to do is check the PH of your soil. If that is over 8 or under 6 then that could block your plant from obtaining iron out of the soil. if your soil is lacking iron you can simply stick a nail in the soil. as the moisture reacts with the iron in the nail, it will form iron oxide which your plant can use. one nail. don't go dumping a box of them down . you will turn your soil toxic. there are plant foods that have iron in them. tomato plant food has iron and evryother nute that your girls need. But first I would recommend checking the PH first
