2. Rice cooking water as fertilizer for orchids

Cooking water from certain foods, such as rice, is very effective in fertilizing orchids,   as long as this water is not salty.   After cooking the rice, collect the cooking water and let it cool   before using it to water your orchids.

In addition to rice, you can also use the cooking water from the potatoes. This tuber can provide your plants with potassium, but also a little phosphorus. To do this, simply save the cooking water from the potatoes and use it to water your orchids when it has cooled. You can also cook small pieces of unpeeled potatoes and   then add them directly to your pot.

However, be careful   not to use too much cow’s milk,   as this can create bad odors and slow the growth of your plants.  In no case should it replace irrigation with water. Also prefer skimmed or semi-skimmed milk, rather than whole milk.

Tip:   To fight fungal plant diseases, dilute 1 part milk to 4 parts water and water your plants with this solution once every 2 to 4 weeks.
