Garden Pest Sprays

Garden pest sprays do not have to be toxic to everything. Most of the sprays that are available are just that. They are broad spectrum pesticides, which means they kill everything. Good bugs and bad. Organic land care has a more direct approach when it comes to controlling pests in the garden.


Some insects are on the planet, in part, to eat weaker plants so they are not consumed by animals further up the food chain. It is only when the populations get out of balance that we need to step in and adjust things. When that happens, some of the following concoctions will help keep specific pests (not all of them insects) from throwing off the balance of your garden.

Chamomile for Seedlings (not really a garden pest spray but..)

Basically make some relatively weak chamomile tea.

Allow it to cool to room temperature and water your seedling with it using a spray bottle. It helps to prevent damping off, where seedlings wither and die before they get a chance to really get going.
