Do the baby leaves fall off?

The cotyledons, or seed leaves, provisionally nourish the seedling with carbohydrates, proteins, and lipids as fuel for the seedling's early growth via enzymatic degradation. When the true leaves emerge and carry out photosynthesis, cotyledons are not needed anymore. They hence go for senescence, where degradation in chlorophyll happens due to enzymes, resulting in the yellow color, and cell dehydration, leading to drying. The withering and shedding of leaves are processes carried out spontaneously under the influence of ethylene through hormonal control, making it an integral part of the growth cycle.

Yeah xD Only that... what a bull... Lisen to organo... he,ll teach u T_T

Technically, cotyledons are not leaves.........their only function is to protect the growing tip as it pushes up out through the soil. They will nearly always shrivel up and fall off/die within 3 weeks or so after germination. "Problems" with cotyledons is not related to nutrition or soil conditions. Having them die and fall off is normal and somewhat to be expected.........it is not a sign of any sort of issue.

if there'd be a deficiency then seedling ll eat it up, if not they will stay perfectly 001 has a right point (1st part)

not always. my cotys usually stay healthy, but i don't think it is meaningful. might reflect nutrient balance and availability in some small way. I often rip them off anyway... peels away that 'skin' off the stem while doing it. This is 2-3 weeks after sprout and they are well-shielded.. more of an ocd behaviour than for a real cause.

Hi, du hast recht die Keimblätter werden meistens nicht so groß und sterben ab.

Yep, that’s exactly what happens 🙂 The cotyledons (seed leaves) only feed the seedling in the very early days. Once the plant has a couple sets of true leaves and can photosynthesize properly, the cotyledons have done their job. They’ll usually turn yellow, dry up, and eventually drop off on their own. Nothing to worry about – it’s totally normal and just part of the plant’s life cycle.
