do good weed seeds float or sink

How to grow Pedunculate oak

Collect the acorns from the ground in the autumn, often following the first strong wind. Acorns that have fallen onto grass are less likely to have been damaged than those that fall onto hard surfaces.

Check that the acorns are healthy. You can do this by simply looking at them and feeling them if you don’t have many. Any visibly damaged or with holes in are unlikely to grow.

If you have quite a lot, you can put them into a bucket (or buckets) of water.

If they float, they may not grow, but this isn’t foolproof! Many that float may still grow.

Try squishing a few that float between your fingers. If they are firm and look healthy, plant them anyway. You could cut some in half to see what they look like inside – watch your fingers! Any signs of insect damage, bruising or rot will probably cause them to fail.

Extraction and storage

In the short-term, acorns can be stored in bread baskets for a week or two. They must be kept cool and out of direct sunlight.

There is normally no further extraction needed with acorns after collection. They can be separated from any twigs or leaves if you have the time, but it is not essential.


Acorns are not dormant, so they need no pretreatment for them to grow. In fact, our main difficulty is stopping them from germinating until we want them to! If they are kept in damp conditions, they will grow very quickly, even without soil.


Plant two acorns in a pot filled almost to the top with peat-free compost. Any container will do – a yoghurt pot or root trainer. Make sure there are drainage holes in the bottom, and just cover the acorn with compost (about 2cm deep). Protect the acorns from predation! Mice and jays love them, so cover them over with fine wire mesh to keep them out.

If you are sowing outside, sow them in good soil to a depth of 5cm and firm. Aim for a density of about 100 plants in a square metre. This means sowing about 200 acorns.


Never let your pots dry out! Stand them in a shady, sheltered spot, out of doors and water, from the top, until the seedlings emerge. From then on, water from below by placing the container in a tray of water and let the compost soak it up through the drainage holes. Water plants in seedbeds if needed.


Then wait and be patient. It could be May before the seedlings appear. Your oak seedling will grow quite happily in a 1-litre pot or root trainer for the next two summers. Feed with a liquid fertiliser during the summer to encourage maximum growth, but do not over feed! This can scorch the roots.


When your oak seedling is at least 200mm (8 inches) tall, it is ready to be planted into its permanent home. Choose a place with enough space for your oak to grow. Remember that it can grow up to 45m high! Prepare the site well by clearing away any weeds or grass and make a hole big enough to accommodate the root ball. Plant carefully in the hole, to the same depth as it was growing previously and firm back the soil.

Palm Tree Seed Germination: What Does A Palm Tree Seed Look Like

If you want palm trees in your backyard, growing palms from seed is your least expensive alternative. In many cases, it may be your only alternative, since palm trees grow in a way that makes it impossible to propagate them through asexual means like cutting, layering, or division.

Planting a palm tree seed is more complicated than you might think, however, since it’s important to get mature seeds, plant them promptly, and have patience. Palm tree seed germination is not a matter of weeks but months or even years. Read on for more information.

What are Palm Tree Seed Pods?

When you want to start growing palms from seeds, you definitely need to obtain seeds. While you can buy them in commerce, you can also get them from the seed pods of flowering palms. Fresh seeds tend to germinate more quickly. The pods are the balls that form near the flowers and contain the palm seeds.

What does a palm tree seed look like? That entirely depends on the species of the palm. Some are small and bright red, like holly berries; others are big as bowling balls, like coconuts. You should collect seed once the fruit is 100 percent ripe or when it falls from the tree.

Palm Tree Seed Viability

It’s generally best when you are growing palms from seed to use the harvested seeds quickly. Seeds of some palms only stay viable for a few weeks, although a few can retain viability for a year or more with proper storage.

A popular test to determine if a seed is viable (and can germinate) is to drop it in a container of warm water. If it floats, don’t use it. If it sinks, it’s fine. We should note that experts find this test inexact, since, in testing, a good number of the seeds that floated will sprout just the same.

Palm Tree Seed Germination

Palm tree seed germination can take a long, long time. According to experts at the University of Nevada at Reno, most palms take 100 days or more to germinate, with an average germination rate of less than twenty percent.

Before planting a palm tree seed, you need to remove the exterior of the seed pod, scraping off the fruit, until just the seed remains. If you are only planting a small number of seeds, soak the seeds for a few days in water, then cut the fruit tissue away with a knife.

Plant each seed in a small container, covering it thinly with soil or leaving it half buried. In nature, palm seeds are dispersed by the wind and animals and germinate on top of the soil rather than being buried in soil to grow.

Keep the pots in a warm, humid location. You can also wrap the pot in a plastic bag to hold in the moisture. Keep the soil moist and wait.

Best Way to Germinate Cannabis Seeds

Finally, you have made up your mind to grow pot seeds. You have bought a pack of cannabis seeds and have gathered cultivation materials. With everything you need by your side, you are all set to grow cannabis. But first, you need to do the initial step: Germinating Seeds.

What is Germination?

Germination is the initial stage of the weed growth cycle. It is the process that brings the pot seed out of the hibernation period, and kick starts the growth process. After all, the seeds won’t start developing roots in the bag.

The seed germination starts when it receives environmental signs allowing it to know that the surroundings are perfect to begin growth. This process is also known as ‘popping’ seeds. Thus, germination brings the cannabis seed out of the hibernation period and starts the growth process.

When a seed enters an environment with enough moisture, it grows in size and gradually breaks out of the shell. A germ or seedling forms and roots emerge from it. The roots then help the small plant to absorb nutrients from the soil. The seeds naturally grow roots facing down and stems that stretch upward, allowing the baby cannabis plant to feed on earth and light easily.

It is essential to get good cannabis seeds for germination. Only then will it grow out and become a high-quality cannabis plant. Cannabis seeds that are too green or fresh-feeling show that they are not mature enough. Whereas white, pale-green, and very dark cannabis seeds might have problems sprouting.

If you don’t want to pop your seeds yet, keep them in a cool and dark place until germination. The right tips can help you with that.

Tips to Follow Before You Begin to Germinate Pot Seeds

– Keep your pot seeds in a sealed plastic bag. You can keep them in the fridge and take them out when you want to plant them. Remember, cannabis plants sprout in spring.

– Dip your pot seeds in a glass of water. Make sure the temperature is (20°- 25° C) for twelve hours.

– If you soak your seeds in the water for more than 24 hours, you will deprive them of oxygen. As a result, they will drown and won’t sprout. A weed seed that sinks after twelve hours is viable and is adequate for germination. If your seeds are floating after twelve hours, they won’t sprout soon.

– Next, you need a water sprayer and have to spray your germinating seeds. If you plan to use a dry napkin, don’t because it will destroy the recently sprouted tap root and kill the plant.

– It is essential to keep track of germination dates along with stages during the growth period. Just don’t forget about the germinating seed. If left out for too long and not planted, the seed might grow a long taproot but will eventually die without the right growing conditions.

Set reminders so that you remember. Follow the germination and growing process step by step for success.

How to Germinate Cannabis Seeds?

Our step-by-step guide will get you through the germination process like a breeze. You will need two plates, saucers, and moist tissue. Without further delay, let’s get into it:

First Step – The Setup

Line the first plate’s bottom with some layers of wet tissue. Then drain the access water off the plate, if any.

Seeds go on top of the tissue and give them as much space as possible. Next, place few more layers of moist tissue on the seeds, again draining the excess water.

Lastly, cover that plate with the second plate. Make sure the plate is upside down so that a clam-shell shape is made. It will make a moist and dark environment necessary for germination.

Second Step – Germination

Place the plates in (21ºC) and make sure it’s away from direct light. Keep an eye on the seeds and check every day to ensure that the tissue is not dry. If need be, spray it with water.

In a few days, all the seeds will open, and roots will come out. Cannabis seeds commonly open within 72 hours of germination. It rarely happens that the seeds take up to 10 days or two weeks to bring out the root.

As soon as the first few millimeters of the root come out, carefully transfer it to a container with coco-fiber, soil, or Rockwool.

Third Step – Potting

You need to make a hole in the container twice as deep as the seed so that the germinated cannabis seed is 2-5mm below it.

Place the root of the cannabis seed first in the hole and then cover it with a bit of quantity of the growing medium. Make sure it’s just enough to stop the light. Not too much to block the space of the seedling when it grows.

The cannabis seedlings come out between 24-72 hours once the germinated seeds are planted.

Fourth Step – The Seedling Stage

The new seedlings need to have access to bright light when they emerge. Therefore, you need to be careful in the first two weeks, as at this stage, the seedlings are delicate.

Seedlings outdoors need to be adapted to direct sunlight by putting them on a windowsill indoors. It will increase their exposure to direct sunlight. Do it for an hour or two a day.

Seedlings for indoors come out in an artificially lit environment with zero problems. If you are using HID lighting, seedlings need to be at a minimum distance of 50-80cm from the light. If you are using fluorescent light, then the seedlings can be at an average distance from the light.

Final Word

We hope that our guide has helped you figure out the right way to germinate cannabis seeds. You need to consider everything, including the lights, optimum temperatures, potting the seedlings, and finally transferring them outdoors or under the light indoors.

It’s a simple and easy process but requires a lot of patience. Remember, patience is the key to success.
