So do you know where i can buy good topsoil/earth/humus/soil/mud?
My lawn about 600 sq ft has lots of small rocks, construction sand and construction leftovers. i have dug up almost 6 inches and looking for topsoil for turfing. Havent decided phillippines or pearl grass. Would appreciate any advice? thank you
Hi Sorry did not read earlier.
turfing or grass this is what you should do, the easy and cheapest way.
1. You should dig up to 2 feet, if not 2 1/2 feet. Level the ground using a spirit level.
2. Go buy mud (soil), the yellow colour type plentiful and cheap by lorry load fill up the dug areas to 2 feet and 2-3 inches thick (The soil subside with time as there are many air-pockets in between and it will sink). Try level it using long piece of spirit level. Cant find a long one, use a plank/ straight wood 1x2x6 and stick the spirit level on top of the wood. When filling the mud never compact it, just fill and level on the dry. Break the big pieces into smaller with digging tools.
3. Leave it alone let it settle, wait for heavy rain. Real heavy rain for once or two times. The rain not only level out the soil but also even out the compactness of the soil underneath.
3. Then go hardware shop buy sand as topsoil for 4 to 6 inches thick, not just any sand. Buy river sands, the yellow and orange type.
Let me explain this:
1. For plant and grass to grow well you need a layer of mud to hold water all the time rain or shinee.
2. The yellow mud contains little or no wild plant seeds. If you buy humus or old top soil you will get unwanted wild plant spices and out grow your grass and hell lot of work later pulling them up everyday as the wild seeds start to grow.
3. Likewise the sands contain little wild plant seeds. Most grass or plant die when it is submerged in water for too long and the exposed part will rot. The sands will drain away excessive water. That is why you must level the mud and sand ground so as to avoid having pool of water.
4. The mud absorbs water and expands as it is saturated and became impermeable, that is why you must have a layer of sand.
5. The yellow mud and yellow river sands not only void of wild seed but also nutrient, no humus. What needs to do is add fertilizer and overcome this issue.
6. Please note that unlike when you filling the area with mud a bit higher because it will sink, the sand will not compact further or sink but leveling it out when heavy rain.
7. The sand also allows faster spread of the grass and not to worry that the root of the grass have to grow deep to find the water source reaching to the 4-6 inches getting to the mud. A healthy grass can reach it within a day!
8. Please also note that the looser the top layer of "soil" the faster the plant spread and taller it grows. When ground is hard the grass is short and soft it grows taller than usual.
In summary:
Mud, to hold water. Not too thick so as to allow excessive water to move down via capillary action. 2 feet thick will hold lot of water. if too thin if you forgot to water the grass and no rain your grass turn yellow in less than a month.
Sands, allow grass to spread and drain excessive water. Too thin you may have pool of water after heavy rain, too thick your grass grow too tall and you need frequent trimming.
