Readers of the You Grow Girl book might recall that I love a little milk mixed with water as a tomato disease preventative. Okay, I probably didn’t go so far as to indicate a “love” for the concoction but I will say it here: the tomato plants on my rooftop garden benefit from regular applications throughout the growing season and have been disease-free since I began this experiment a number of years ago. You can’t not LOVE those results. I’d cuddle a milk and water concoction on the couch while sharing a bowl of popcorn and a movie with results like that. After the movie we’d play some non-competitive board games and catch The Colbert Report before settling into our communal sleeping bag for the night. I LOVE these results.
Here’s what I do. Organic milk tends to go bad in the fridge faster than non-organic. I only drink milk in my cappuccinos so I often have lots of spoiled milk in the fridge. I dilute the milk with water to a minimum 50:50 ratio (I often dilute much further than this) and either pour it directly over the plant leaves or pour it onto the soil at the roots. I used to put it into a spray bottle first but am too lazy to take that extra step now-a-days.
I should add that this is the only time I water tomato leaves directly. I am careful to water the soil only on all other occasions. This is because tomatoes do not like wet leaves and can develop fungal diseases as the result of too much humidity and moisture sitting on the leaves for long periods of time.
One of my favourite things about gardening is experimenting and trying to improve on old ideas. Last year I figured I might as well mix up my milk remedy with my fertilizer routine. My thought process is that perhaps it all works better when it’s mixed together. I mix the same water and milk solution and add a splash of sea kelp and a dash of fish emulsion to the mix then pour the whole thing onto the soil.
It doesn’t smell great but the plants like it. And I like tomatoes. If it means more tomatoes come fall then I’m all for it.
Hint: If you’re not a milk drinker you can make up the same mix using powdered milk. In fact many people swear by dry powdered milk mixed directly into the soil.
