Here’s a curated list of organic, concentrated fertilizers and bug repellents/insecticides that you can dilute and apply with a sprayer to vegetables, fruit trees, and other edible plants. These are suitable for organic gardening when used according to label instructions (note that “organic” here usually means certified by OMRI or based on natural plant-based ingredients) — and most are made to be mixed with water and sprayed on leaves or soil.

Here’s a general approach (always follow the product label for exact mixes):

Read the label first: Check dilution ratios — most horticultural and neem concentrates require a specific mix (e.g., 1–2 tbsp per gallon of water).

Mix thoroughly: Fill your sprayer with water, add the concentrate, shake or agitate, then apply evenly.

Spray early/late in day: Avoid spraying in direct midday sun — work in early morning or late afternoon to prevent leaf damage.

Reapply as needed: Many organic repellents need repeat applications every 7–14 days or after rain.
