Plant Pollination

Tomato Flower

Plants grown in a Hydroponic System need to be pollinated in the same way as if growing the plants in soil.

Plants that are growing outside will need minimal pollinating, while if they are inside or in a glasshouse the plants will need some assistance in pollinating.

Pollinating the flowers will ensure that you have the highest flower setting rate possible and in turn the largest possible quantity of fruit on your plants.

Hand Pollination

I prefer to use hand pollination and you would be forgiven for thinking that hand pollination sounds like a very painful slow process it really doesn’t have to be.

Paint BrushShaking or Tapping

I currently have a lovely crop of Tomatoes growing in my Hydroponic System.  I pollinate my tomatoes by tapping the flower stem with a artists paint brush a couple of times, this is all that is needed to set the flowers.

Brushing

The paint brush can also be used to gently brush the pollen from the flowers stamen onto the pistil.  This method can be time consuming and is better for plants that have a few larger flowers.

Hair DryerBlowing

Strawberries can easily be pollinated by using a hair dryer on COLD and blowing air onto the flowers.

Spraying

Another method to pollinate flowers is to spray the flowers with water.  It is best to do this first thing in the morning before the plant has any sun on it, spraying at night is also another option only this can put the plant at risk of getting mold on it as the humidity level around the plant over night will be a lot higher.

Setting Agents

There are a number of Setting Agents that can be purchased from your local garden centre.
