- What is volcano soil?
Soil that have been formed where there are lots of volcanic activities. It tends to be rich in nutrients but with lots of volcanic ash.
- What is vermiculite?
Vermiculite is magnesium-aluminum-iron silicate. This is one interesting substance that does not decompost but hold moisture very well. It does not drain water but rather holds water. It is a bit spongy when touch. It is typically used in some farms to place in seedling tray to retain moisture to keep the delicate young seedlings soil moist throughout the day.
- Can we just use soil without the rest?
Of course if your soil is loomy, rich and drain well.
- What kind of planting we need coconut husk?
For me, it is best for root vegetables like ginger and sweet potatoes. They like very loose media. Little soil plus coconut husk (crushed and fine) or cocopeat work very well for this group.
- Is it good to add charcoal to soil?
For edibles, I don’t usually use them. Typically use for ornamentals like orchids.
- What are coco chips for?
Typically used by some as top cover for their garden. It looks pretty. But generally, not commonly used for edibles growing.
- When is cocopeat/husk best used?
A general compost:sand of 80:20 ratio is good for beginner growing. However, root vegetables like ginger, sweet potatoes, radish prefer very loose media. So after preparing your media of soil + compost mix. Use that mix and mix with cocopeat at 50:50 ratio, do not add fertilizer to base mix if you are planting rooting vegetables.
- With regards to sand, should we get coarse sand (those used in construction) or lawn (fine) sand?
Coarse sand generally works better for herbs. I do use lawn sand for vegetables as they are easily available. So far not too bad.
