How to store peach pits for planting:
Peach pit seeds are very useful when they are planted in soil with good drainage. However, if your soil is not well drained or there is no water at all, then the peach seeds will not germinate properly. You have to keep in mind that you need to provide adequate moisture during the growing season so that the seeds germinate successfully.
The best way to ensure that the peach seeds germinate successfully is to keep them moist for about two weeks before planting. You can use a plastic bag or even a paper towel wrapped around the pit. Do not cover it completely because then you would lose most of its air space which will affect the germination rate. Keep it damp but not soaking wet.
You can place your peach pit seeds in a bowl filled with water and leave it overnight or even longer if necessary. If you don’t have any other container, just put the seeds in a paper towel and tie it up tightly. Place it somewhere out of direct sunlight.
If you want to make sure that the seeds germinate faster, then place them in a glass jar or some other kind of airtight container such as a Tupperware box. Add a few drops of water every day. If it is still not moist enough, place the container somewhere warm such as on top of a fridge, in the airing cupboard or near a radiator.
Make sure that there is good drainage in the soil or place a saucer under the container to catch any water that may be spilled.
How long does it take for a peach seed to sprout?
It will take a few weeks before you see any signs of life. You should see a tiny little root poking out of the soil after about one week. The first “leaf” that starts growing is not technically a leaf at all. These are called cotyledon and appear as a yellowish-green tinted spike. The next leaf that comes out is the true first leaf. This should be a darker green colour.
After the second leaf emerges, the stem will start to thicken and grow very quickly. It is important that you keep the soil moist at all times during this period. Place it somewhere warm such as near a heater or somewhere outdoors in the sun. However, if the sun is too hot, you should place it in the shade so that it doesn’t get burnt. If it does happen then the burn can cause the tree to die.
After about two months, the stem will have thickened to about 5 inches and will have developed multiple branches. At this point, you can transplant it outdoors but only do so if there is no more danger of frost. You should also keep an eye on the leaves because if they start to discolour or turn brown then the tree may be getting poisoned and you should move it elsewhere.
These are all the steps that you need to take to grow a peach tree from its seeds. It is not difficult but you do need to be patient and have a bit of spare time on your hands.
