Water plants in a beneficial manner using household compounds. Watering plants with household compounds can beautify them or rid them of insect infestation. Household compounds are not to be confused with household chemicals, as a compound is the combination of two or more elements or parts. Household compounds consist of items used throughout the house--either left-over or new items can be used. While none of the household compounds will harm any plant, they will benefit the plants for which they are intended.
Combine compost, made from organic matter such as left-over or spoiled food, leaves and grass clippings with nonchlorinated water. Mix 1 lb. of this compost with 1 gallon of water and allow it to steep for three days in open sunlight. Strain the compost tea and use it to water plants.
Treat withering foliage by mixing 1 tbsp. of castor oil with the amount of water shown on the label directions for a regular medicinal dose.
Wash leaves of a plant that is infected with scales or spider mites with a solution of 2 tsp. of household detergent with 1 gallon of water.
Water plants with the left-over water, after it cools, from boiling potatoes, rice or spaghetti. Plants do well with starch.
Apply diluted tea or coffee--used the same as water--to an ailing fern once each month until it recovers.
Mix a solution of crushed egg shells and water and allow it to sit for 24 hours, but no longer. Water the ailing plants and throw away the solution. Collect egg shells, repeat the process and water the plants regularly with this solution.
