I am going to point out things to look out for in the early stages of crop growth.
Seed Quality – You might have done everything right but your seed refuse to sprout, it tells you that your seeds are bad or too old. Fresh seeds germinate easily and fast. So when buying your seeds from seed vendors check the packs well to know old the seed is and check to see whether the seed have holes in them.
Planting Depth –Do not plant the seed too deep in the soil, and with too much of moist and coldness the seed will rot. Make sure you follow the instruction on the seed pack or bag very well
Damping off – this is caused by fungi, it makes the stem of the plant turn brown and bend at the soil level. To prevent this you have to remove the humidity dome right after the seed sprout out, by leaving it on, it creates the necessary conditions for pathogens and pest to live and strive.
Mold – Molds are white hair like growth on the soil surfaces. Mold thrives best is dirt that is too wet and there is poor ventilation around plants. To prevent molds you have to increase the spaces or planting distances between plants to let improve air passage between them and also reduces the water content of the soil.
Bugs – If you have houseplants with pest issues, keep your seedling trays far away from them. The most common indoor seed-starting pest is the fungus gnat. It looks like a small but sluggish fruit fly. Gnat larvae survive only in a moist environment, so cut back on water—once seeds have sprouted, let the top ¼ inch of soil dry out between watering.
