Pointed seeds- The radicle is normally on(or emerges from) the tip of the seeds, so you’ll want the tip to be pointed downward when sowing. These include watermelon, squash, cucumbers, and corn seeds.

Which end of a cucumber seed goes up?
Place seeds on their side or with the pointed end facing upwards, two per pot of seed compost and about 2 cm deep. Water well and leave to germinate. The seeds should germinate within 5-7 days.
Which end of the seed goes down?
Scott believes that pointing the seed in the right direction (meaning with the root in the down direction) when planting will improve germination rates and vigor of the plant. As a plant begins to grow, an embryonic root emerges from the seed, termed the radicle or primary root.
Do you plant a seed with the sprout up or down?
Place the sprouted seed on top of your growing medium, cover with dry seedling mix, mist with the spray bottle, and place under the growing lights. Be very careful not to damage the root. If you do, the sprout will die. If the root has grown into the paper towel, snip around it and plant paper towel and all.
What happens if a seed is planted upside down?
Whether a seed is sown upside down, right side up or on its side, it has the ability to position itself so stems grow upward and roots grow downward, reports Terrior Seeds. Seeds contain growth hormones that respond to gravity and rotate the seed to the correct orientation.
Which way do you plant cucumber seeds?
Seeds with points such as watermelon, cucumber, squash, pumpkin and corn should be planted point or radicle down. This gives the seed a head start as the root will emerge from the radicle and head straight down, while the shoot or stem will work toward the sun.
How do I plant cucumber seeds?
Sow two seeds about an inch (3cm) deep, then water well. Cucumbers need temperatures of at least 68ºF (20ºC) to germinate, so either place pots in a propagator for speedier germination, or simply wait until late spring to get started. Once the seedlings appear, remove the weakest to leave one per pot.
How do you plant seeds know which way is up?
Plants have the uncanny ability to send their roots down and their shoots up, even if the seedlings are rotated. The plants are sensing gravity.
What would happen if you accidentally planted a seed wrong side up?
The radicle is located differently depending on the type of seed, but the important thing to remember is that if you accidentally plant a seed with its radicle facing in the “wrong” direction (upward), the stem and root will change direction naturally due to geotropism, thereby correcting the issue.
What do you do after seeds sprout in a paper towel?
Removing Seeds from the Paper Towel
A much better way to do it is to carefully tear the paper towel around the root and leave a small piece of it attached. It won’t harm the plant to pot it up with the paper towel attached to the roots as it’ll disintegrate fairly quickly in the soil.
How deep do you plant a germinated seed?
The rule of thumb is to plant seeds at a depth equal to two or three times their width. It is better to plant seeds too shallow than too deep. Some seeds, such as certain Lettuces or Snapdragon, need light to germinate and should not be covered at all.
How long after planting germinated seeds do they sprout?
between 3-10 days
Seed/Germination
They can take anywhere between 3-10 days to germinate, although it can happen in as few as 24 hours or as long as 2 weeks. To germinate, you can place the seeds in a damp paper towel, which you should then place in a dark place, such as inside a drawer.
Why do seeds grow faster in the dark?
The light slows stem elongation through hormones that are sent down the stem from the tip of the stem. In the darkness, the hormones do not slow stem elongation. The seeds in the dark-grown condition rely upon the stored chemical energy within their cells (lipids, proteins, carbohydrates) to power their growth.
Why do seeds grow downwards?
It is essential for roots to grow down so they can explore the soil and maximise their water uptake.
What plants can grow upside down?
What plants can you grow upside down?
- Tomatoes;
- Peppers;
- Eggplants;
- Cucumbers;
- Squash;
- Beans;
- Various herbs.
Why won’t my cucumber seeds germinate?
Keep the Cucumber Seeds and Their Soil Moist
Even with ideal soil temperatures, cucumber seeds will not germinate without enough moisture. In fact, seeds will die if they dry out too much after the germination process has begun. A spray bottle is handy to keep soil moist for cucumber seeds that are trying to germinate.
How long does it take to grow cucumbers from a seed?
50 to 70 days
Although cucumbers can run into issues with pests, they are still pretty easy to grow from seed. Most varieties are ready for harvesting in 50 to 70 days.
How often should I water cucumber seeds?
Plan on watering your cucumber seedlings every few days, or even daily. Keep an eye on the surface level dryness of the soil, and give the seedlings a sprinkle if it doesn’t look moist.
How many cucumber seeds are in a hole?
one cucumber seed
How many cucumber seeds do you plant per hole? You should only plant one cucumber seed per hole if you’re using a fresh new packet. For older ones, plant 2 per hole, and then thin them later if more than one germinates.
What is the best way to grow cucumbers?
Cucumbers like warmth and lots of light! Cucumbers require fertile soil. Prior to planting, add about 2 inches of aged manure and/or compost to the bed and work it in to a depth of 6 to 8 inches. Soil should be moist but well-draining (not soggy) and have a pH of around 6.5 to 7.0.
How many cucumbers do you get per plant?
Depending on who you ask, a healthy cucumber plant can be expected to produce 10 large cukes or 15 small ones within a harvest period of about three weeks.
