"Rabbit is what you need," he told me. "My father swore by it."
Before I could respond, he adjusted his hat and told me: "You need to get your hands on some rabbit pellets." And off he walked.
I haven't seen him since, but clearly his words keep coming back.
I've also read that sheep manure is an excellent option. Drier, less odiferous, high in phosphorous and potassium.
Unfortunately, we don't know anyone who raises either. They're around, I'm sure, but you have to know someone well or be introduced by a reputable party before you start asking to take poo off their hands.
Years ago, we knew a lady who raised ostriches and had friends who raised emus. Back then, we weren't as serious about gardening. A pity. Today, I'd welcome an opportunity to give these avian manures a try.
Like so many things in life, diversity and moderation are probably the essential ingredients when it comes to manure.
For now, we'll stick to composted horse manure because we have a steady source and it's done wonders to transform our century-old lawn. But if we can get our hands on rabbit or sheep, we won't say no!
