How long does cress take to grow from seed?
Germination takes place within a couple of days (24 hours, if you’re lucky) and the cress is ready to harvest when it’s around 1½ to 2 inches high (which will be, depending on the type you’re growing, five to seven days later).

What happens if you let cress keep growing?
The true leaves of cress are feathery and divided and plants grow to around six inches high in about four weeks. Leave it longer and it will begin to go to seed, but if this happens don’t just throw them out. Cress tends to lose its flavor when cooked, but it certainly adds texture and a mustardy warmth to any salad.
Does cress need sunlight to grow?
Cress grows well in cool, shady areas. You don’t want to grow cress in direct sunlight. You only need 1-2 square feet of garden space to plant cress. Garden cress is also called broadleaf cress.
Why do seeds grow faster in the dark?
(Explanation: seeds store a lot of chemical energy in the form of fats and proteins that can be used to grow in the dark. Once this stored chemical energy is exhausted, the plant requires light to grow taller.)
Does cress regrow once cut?
Does cress regrow after you cut it? Basically not. However, often there are still small seedlings among the already mature plants. They may still be able to thrive after a first harvest.
Why can cress grow without soil?
Cress is an extremely undemanding plant. It does not need soil and can germinate on cotton wool! The cress seeds themselves also contain a small supply of nutrients, and so the plant is pretty much self-sufficient and can grow and flourish under very basic conditions… even without soil!
How much water do cress seeds need?
The overall result therefore was that 3ml of water was the minimum amount necessary to enable the water cress seeds to germinate.
Why do seeds grow better in the dark?
Most seeds germinate underground, so their first stages of growth are naturally in the dark. Seedlings can grow for a certain time in the dark as they have a limited chemical energy store in their cells. Once these energy stores run out, they need light exposure to produce their energy using photosynthesis.
Should cress be grown in the dark?
The cress seeds begin to grow significantly after a day or two and end up being more than 3 times as high. In the dark, the plants have no light to use in photosynthesis. They will therefore put all their energy into growing as high as possible to increase the chances that they may still encounter a ray of sunlight.
Can seeds germinate without sunlight?
Some seeds don’t need light to break through their seed casings and sprout. Most seeds germinate best with controlled amounts of UV generation, but there are seeds that germinate in the absence of light. Furthermore, there are plants that get enough just light in highly shady areas of a garden or even in darkness.
Does more light make plants grow faster?
Sugars fuel plant growth, so the more light a plant is exposed to, the more energy it will create and the faster it will grow.
