Yes, all seeds have an average "life span", but the length varies between species and is greatly influenced by storage conditions like temperature, humidity and light. As a rule of thumb, dry, cool and dark, possibly in the original sealed package is the best way to store seeds. The standard garden veggie seeds should typically1 last at least two to three ...

Probably the biggest disadvantage of using soil blocks is the up-front cost. If you want to get the biggest advantage, you'll want to have the ability to transplant from smaller blocks to larger blocks. For example, you'd start tomatoes in 2" blocks and then transplant up to 4" blocks. I've seen a number of people recommend the little tongs/tweezers, which ...

Tomato seeds that have never been dried can germinate. I've tried it. Tomatoes can actually germinate inside the fruit, sometimes (wherein the fruit is still good to eat, at that). I've read that the gel sacks around the seeds are supposed to inhibit germination. You may have greater success if you remove the sacks. I could be wrong, but I don't think ...

The aim of it is to mimic the action of a bird's intestines prior to pooing out the seed - many seeds which pass through a bird's digestive system germinate more readily, because the outer coating of the seed has been either thinned or softened as a result, making it easier for the seed to germinate. Chili pepper seeds (depending on variety) are known to be ...

If you really need one plant growing in the center of the pot, then get 3 or 4 pots, mark them with numbers (so you don't bias your experiment by choosing the one that is "growing the best" or whatever) and plant just one seed in each pot. Use the lowest numbered pot where the seed germinates for your experiment You can eat the other radishes in a salad, of ...

That looks like fine root hairs on the hypocotyl of a normal , healthy seedling still in the cotyledon stage. These root hairs greatly increase the surface area of the root and are thought to aid in nutrient absorption, anchorage and microbial interactions. Edit: It does look like the root has pushed the seedling out of the medium though (maybe they are ...

You don't need any fertiliser at all to start with - the clue is in the word 'starter'. You're only meant to germinate the seeds, then wait till they have 2/3 sets of leaves (one cotyledon pair and one true leaves), at which point you move them into individual pots containing probably seed and cutting compost - then move them up into potting compost in ...

You don't plant the whole bulb, but split them into cloves, and plant each of the cloves separately. Each clove will develop a new bulb that will be oriented correctly. I doubt it matters if the tapered end of the clove is pointed up or laterally since the stored mass is used to grow the new leaves which then create the new bulb. However, if you plant the ...

Yes, this will affect the seeds' viability but depending on your climate, it may not be enough to worry you. In general, lettuce seeds last about 2-5 years. If your climate is hot and humid, the shorter end of that period will apply. If it is cool and dry, they might last longer. If you are in a hot, humid climate and want to extend their life, you can ...

This is a Delonix regia, a tree very similar to more famous Albicia julibrissin, but with entirely different flowers: https://en.m.wikipedia.org/wiki/Delonix_regia On propagation, from www.thespruce.com: Seed germination and cuttings are used to propagate this tree. Seeds will need to be sacrificed first to break open the seed coat and allow water ...

I disagree with @peer's answer. I've been making my own seed mix for the past three years, I have never sterilized it, and I only once had a problem with damping off when I covered a flat with plastic wrap. (So that's 1 flat out of maybe 80 or more that had a problem, and I'm pretty sure that was caused by too much moisture and not enough air flow.) Elliot ...

The end of your seed with a lighter area on top is called the eye, place the seed with its eye facing up. Cover the seed with half an inch (1.27 centimeters) of soil. The seed should sprout within a few weeks. Water your plant with lukewarm water whenever you see the soil is a bit dry. Mangos don't need a lot of water.

The seed coat is hydrating. Perfectly normal, just not usually seen when germinating in soil. having played with "germinate on a wet paper towel and carefully plant with toothpick" method, I've seen it. Here's a lovely poster (pdf) (of the science conference type) by Dongfang Zhou, Monica Ponder, Jacob Barney and Greg Welbaum of Virginia Tech - far more ...

Try removing the bag a little at a time over the period of several days so the seedling can acclimate to the unprotected environment. It's going to be just like hardening off any plant.

No need to dry them out usually, and large varieties of tomato will grow exceptionally well with the right conditions. Here in Florida we just slice the tomatoes and lay the slices on top of the soil. The sun does all the work and the seeds fall through the slice and grow up through the rotting tomato slice; almost acting like its own self-made compost in ...

Basically allelopathy is a mechanism where one species of plant affects the growth of another via chemicals (typically exuded from roots). It can be both positive and negative, although gardeners usually use the term in its negative (growth inhibiting) context. A classic example is the black walnut tree which produces a chemical, juglone, which inhibits many ...

What you have there is referred to as a tassel-ear. You are correct that corn is a monecious flower, but the way it develops is a little different. When the flower (both tassel and ear) first form they are perfect flowers (both male and female). During normal development different hormones are sent to the tassel and the ear, causing the tassel-flower to ...

Cherry seeds need both warm and cold stratification to overcome the seed's dormancy. But you can germinate fresh cherry seeds using the plant hormone Gibberellic acid. In March 1969, partially stratified (3 months) seed from 14 families were removed from cold storage, endocarps were removed by cracking, and 10 to 20 seeds from each family were ...

Think of how tomatoes grow "in the wild" fruit drops to the ground, slowly rots, and when conditions are right a new plant emerges. So cut open the fruit and cover it in soil, the results are not surprising. I don't see why this method wouldn't work for people who just want a "tomato". The types of people that will save seeds from store bought tomatoes and ...

What a nice gesture of this animal hospital, sorry to hear about your loss. The best way to keep these seeds is in a dry and cool environment. So not in the fridge (too much moist), and not above the radiator/heater (too hot). If you have a cupboard for storage (is that called a pantry? I am non-native English speaker), that would be the ideal place. The ...

Some seeds will germinate with just warmth and water but if they do not get sufficient light they become spindly and stretched out. These seedlings are weak stemmed and tough to plant out. You get better seedlings by growing them under light. Once they are around the two leaf or four leaf stage you can take the top off your tray and move them into indoor ...

Your best bet would be to try germinating them using a damp paper towel. If they sprout, you're good to go. It probably varies based on how old the seeds are and how they were dried, etc.

Cover it with hay. That'll keep some from getting on feet/paws. Alternatively, just get some flexible green/orange fencing and prevent the dog from getting in that area. I did a 50 foot roll plus a few 3' ground-stakes for under $30.

Growing lilacs from seeds isn’t easy, but it can be done. It can take up to three or four years for a seed-propagated lilac to bloom, though, so you’ll have to be patient and just enjoy watching the bush grow! From Garden Guides: When growing seeds from a lilac, two things are of utmost importance. First, make sure you’re not harvesting seeds from a ...

No, you need to move them into pots before putting outside, and they should be moved once they develop 2-4 sets of true leaves (not counting the first set, the cotyledons) at the latest. The plug of soil in your egg carton won't be big enough for proper root formation, and any plant is only as good as its roots. Move into small pots, grow them on a bit, then ...

If they're still there (not eaten, bored into, etc), then yes, they will grow. I have sunflowers naturalized along the woods' edge in one spot. They return year after year on their own. If you want to be organised, you won't be able to use seeds that fell on the ground (too hard to find), so you'll have to use what you can come up with out of the old heads. ...

Just a quick answer to get started, based on my experience. I never lived in the Puget Sound area, but know it quite well. Will continue to fill in as I have time. Short answer: Get started now, this is the perfect time. On a quick glance I see no plant that you would be too late for, but I haven't sown/planted all of them myself. Calendula will be fine. ...

Dry them off and put them on a paper towel. If they still sprout, you can plant them then.

If you ask yourself what wegetable you should grow at a given time, you should use a seasonality table like this one. This kind of document can help you to chose and optimize your cultures by planning at month scale every phase of your cultivated vegetables. Find a similar document at a local gardening store to be sure it is suitable to your location. To ...

If the soil temperature is adequate, the seeds are good, the depth is correct, then likely the seeds are rotting in the ground or are being eaten by animal life. That's why people use seed mixes to plant seeds into, to avoid bacterial and fungal pathogens, to avoid competition from other plants (allelopathy), and for good drainage.
