I'll never match Gene Kelly and his 'Singing in the Rain' routine, but I've just been dancing around our garden, flinging in the rain, and I feel just as good as Gene ever did.
You see, it's citrus fertilising time, and in recent years I've decided to abandon any pretence to sanity for this special occasion, and as soon as I hear the rain falling, I'm out in the garden with my bag of perfumed chicken poo, flinging it under our fruit trees, while the rain does the other important job – watering in the fertiliser while it gently soaks the skin of one slightly crazy old gardener.
For Australian (and I guess all other Southern Hemisphere gardeners) you should feed your citrus trees twice a year: at the end of summer (late February) and the end of winter (late August).
Now, as for what to use, your choices are many, but I go for chicken poo every time. Here in Australia it's sold under several brand names, but the biggest seller is Dynamic Lifter. Not all Dynamic Lifters are equal, though, so you should check out the labelling before you buy anything, as some products are "organic" and others are "organic-based".
My excuse is that every second time round, I choose rocket fuel over standard fuel, and I think our citrus like that little boost to their diet.
The moral of the story, though, is that whatever you choose, use it now. You can do it in the sunshine and water the fertiliser in with a hose (the boring but sensible option), or you can do it in the rain, dancing around your garden like a slightly deranged, green-thumbed Gene Kelly.
