5 Benefits of Hydrogen Peroxide on Your Plants and Garden (The Mexican Way)

A plant on a window sill dies twice: once from the water it was given, and once from the water that came after. Soil still damp on the third day, a saucer with a puddle in it since Sunday. That plant is not short of water, it is short of air. The brown bottle from the pharmacy, 3 percent hydrogen peroxide, costs about a dollar and buys one breath for a root that is under water. It is not fertilizer and it is not a cure. Its extra oxygen tears into whatever is rotting, is spent in seconds, and leaves water behind. The label in the pot gave you a watering day and said nothing about where the water goes afterwards. None of that is on you. Five jobs, and the point where each one stops. THE FIVE JOBS, AND WHERE EACH ONE STOPS: 1. The drowning pot: empty the saucer, then 1 part peroxide to 4 parts water, 2 cups for a 6-inch pot, poured until it runs out the hole, none on the leaves, then a week dry. 2. The little flies out of the soil: the same weak mix as that day's watering, once a week for 2 to 3 weeks, because eggs keep hatching. Sticky cards for the adults, and let the top inch dry. 3. The seeds, before they ever meet soil: straight 3 percent in a glass jar, 10 minutes for fine seed, up to 30 for beans and corn, then rinse and plant that same day. It cannot wake dead seed. 4. The white dust on squash and cucumber leaves: 1 tablespoon of 3 percent in 1 cup of water, one test leaf first, both sides, evening or deep shade, weekly and after rain. It holds the spread and cures nothing. 5. Last year's pots, saucers and the watering can: scrubbed with hot water and a stiff brush first, because dirt spends the bottle in seconds, then half and half, 10 minutes, rinse, dry in the sun. Half and half only here. One correction, since it rides along with this trick: peroxide on a leaf does not repel bugs or ants. Soap does, 1 tablespoon in a quart of water, underneath the leaves. It goes in alone: never with vinegar, never with bleach or ammonia, and never in a bucket that held bleach. Only the 3 percent brown bottle; the 35 percent sold online burns skin. Capped and up high, away from children and pets. ⚠️ A whole bed going down at once, or a plant black and soft where the stem meets the soil, is past a bottle. Ask a nursery in your own town. One pot tonight, mija, not the whole sill. Empty the saucer, mix half a cup of the bottle into 2 cups of water, pour slowly until it drains, then leave that plant alone for a week. In the comments, one word for what your two fingers found in that soil before you poured: wet, or dry. And your county too, because damp air holds the water in a pot far longer than dry air does. I read every one.
