Tip 1: I have several African Violets in my kitchen window. When I rinse milk glasses and containers, I use the rinse to water my violets. They seem to flourish and bloom frequently.
Tip 2: When my geraniums need watering, I add water to leftover coffee. This makes them thrive; at least until the summer heat becomes intense.
Tip 3: If any of my house plants get aphids on them, I use a Q-tip or cotton ball dipped in alcohol to gently wipe the aphids away. I then try to clean up the area that is sticky with it as well. Most of the time the Q-tip method works and does not seem to harm the plants.
