This is an awesome solution you can make at home and feed your plants during the bud, flower, and fruiting stages of their growth cycle. During the changeover period from growing to flowering, we use CalPhos to enhance roots and strengthen plants. Now that we’re into flowering/fruiting, the natural farming method emphasizes Potassium to enhance qualities like taste and sweetness. To create the fruit extract, we’ll use the same principles we used for HerbaGrow.
How to Make:
Collect fruits. Any fruits can be used. In North America, you can use herbs, or weeds high in Potassium like Comfrey (also a good source of Phosphorus). For the beta-carotene, yellow/orange plants like Carrots, Squash, Pumpkin, etc. We really emphasize Potassium during this time so those plants high in that element are recommended. In Asia we use banana, squash, pumpkin, papaya, mango, jack fruit, pineapple. Citrus fruits should generally be avoided. Recommended “best” combination here in asia is a 1:1:1 mix of banana, squash, papaya. In the west it could be banana, squash, pumpkin.
TIP: if you are growing tomatoes, add tomatoes to the fruits to ferment! Get the plant-specific enzymes, nutrients, etc. Want nice big flowers? Use flowers! Want to help the budding stage? Use flower buds and after fermentation, use concoction during budding time! Ferment small growing fruits if you want to promote fruit growth to produce larger fruits.
Mix fruits 1:1 with sugar. E.g. if you gather 1kg of fruits, mash them up with 1 kg sugar (brown sugar being the best), or 1L of molasses.
Mash up this mixture – don’t use hands!
Add mixture to plastic jug and cover loosely.
It should ferment for 7-10 days.
TIP: 7-10 days is normal for fairly warm (25-30 Celsius) temperatures. In colder temperatures it might take longer. Don’t worry, if you leave it longer no problem.
If you start with 1kg fruits+1kg sugar, you’ll end up with 1.5L juice after fermentation.
Drain the juice after fermentation, into a glass/plastic jug for storage
Leave cap off! For first couple weeks to allow bubbling to finish, then cap it.
Apply as a foliar spray or soil drench. Apply during bloom phase and fruiting phase. Can make separate bloom formulas for each phase.
Strengthens plants during flower/fruiting
Enhances flavor and sweetness in fruits
Performs the same function as commercial bloom formulas but is 100% organic, does not burn plants
Mix with BIM(.5tbsp of each) and apply together to leaves/soil
