What do I do if my seeds won’t germinate?
The primary reasons for failed germination are: Seeds get eaten – mice, voles, birds, and wireworms all eat seeds.
Check to see that the seed is still in the soil.
Seeds rot – planted too deeply, over-watered, or in cold weather, our untreated seeds may simply rot..
What is the best temperature to grow spinach?
Spinach is a cool weather crop that grows best when daytime temperature remain consistently below 75°F–commonly in spring or fall. Young plants will bolt when exposed to temperatures below 40°F, but mature plants can withstand temperatures as low as 20°F.
Is spinach hard to grow from seed?
Spinach thrives in cool weather and short days so it’s best to grow it in the fall for most gardeners. … Plant spinach seeds an inch apart in rows 14-18 inches apart and cover the seeds with a 1/2 inch of soil. Keep the soil moist and after the seeds germinate thin them to stand 3-5 inches apart.
Should I germinate spinach seeds?
Seed germinates in 7 to 14 days at or near 70°F (21°C)—but sometimes seed can take up to 3 weeks to germinate in cold soil. When sowing seed in summer for fall harvest, first place the seed in a folded damp paper towel placed in a plastic bag and kept in the refrigerator for 5 days before sowing.
How do you force seeds to germinate?
One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don’t soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
Can you germinate seeds too long?
Letting the radicle grow too much: if the root becomes too long, it will probably end up getting caught up in the cotton wool or paper and will then break when detached from them before being transferred to the substrate. To avoid this, we need to do two things. First, don’t let the root get too long.
Will spinach grow back after cutting?
ANSWER: As long as the growing point is not damaged during the initial harvesting and the weather is still cool, spinach plants will most likely regrow for two or more harvests. … The leaves should then regenerate for a second harvest within four weeks after the first cutting.
Will 10 year old seeds germinate?
The answer is, yes, seeds will eventually go bad and no longer germinate, but it can take quite a long time. … Most seeds, though not all, will keep for at least three years while maintaining a decent percentage of germination. And even a group of very old seeds may have 10 or 20 percent that still sprouts.
Can you use egg cartons to start seeds?
You can use egg cartons as a seed-starting tray! Depending on the type of carton you have, you can even cut apart the individual sections and plant them, as the carton will biodegrade. Be sure to poke small holes for drainage, and put the cartons on a tray or in a shallow pan to catch any residual water.
What is the best fertilizer for spinach?
Something like 10-10-10 is successful, but a 15-10-10 is preferred. Before planting, use a granular fertilizer. Then switch to a water-soluble fertilizer once the plants are established. We suggest switching to water-soluble because it is easier to feed the spinach plants without disrupting their shallow root systems.
How big should spinach seedlings be before transplanting?
The general rule of thumb is that when a seedling has three to four true leaves, it’s large enough to plant out in the garden (after it has been hardened off).
How many seeds should I plant per hole?
In general, two to three seeds should be planted per hole. Seeds do not have 100% germination rates, so not every seed planted will sprout. Overseeding holes, cells, or pots will help ensure that the number of plants you desire will grow (or more!).
How long does spinach seeds take to germinate?
5 daysThe primed seeds will retain enough moisture to complete the first two stages of germination. After planting, primed spinach seeds germinate in only 5 days, compared to 10 or more for seeds straight out of the packet.
Why are my seeds taking so long to germinate?
Some seeds take two weeks or more to sprout. Poor germination can be caused by overly wet or cold soil, which causes seeds to rot. (The latter can be remedied with a Heat Mat.) If the soil was too dry, the seeds may not have been able to absorb enough moisture to sprout.
Should you soak all seeds before planting?
Soak the seeds for any longer and they might rot. The seeds swell as water penetrates the seed coat and the embryo inside begins to plump up. I presoak just about everything except for the tiniest seeds. But I’m always careful not to presoak my seeds until the night before planting them in pots or in the garden.
Do seeds need direct sunlight to germinate?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don’t confuse seed light requirements with what seedlings need. All seedlings require sunlight.
How often does spinach need to be watered?
Spinach needs about one to one and a half inches of rain or irrigation per week. If you don’t get any rain, you will need to manually water your spinach plants. Instead of one long deep soak, spinach plants will do better with three or four light waterings per week.
How long does it take to germinate seeds in a paper towel?
about five to seven daysThe bag acts like a miniature greenhouse that retains heat and moisture. You should observe seeds sprouting in about five to seven days. The biggest drawback to the paper towel method is that the delicate, sprouted seeds must be transplanted manually to soil or another moisture-holding medium such as vermiculite.
