I have currently got seedlings growing at about 4 to 6cm. Orange, lemon and tangerine. All from shop bought fruit. The system I am using to get the seeds started is to give the seeds a light cold water wash to avoid them growing the own fur coats, fungus. Then place them on wet paper towels folded over to cover the seeds and place in large transparent plastic bags. They are then left in a dark cupboard for about 3 to 5 weeks until they produce roots and shoots before being transferred to pots. So far they seem not to care what they are planted into, soil or pots. I had so many germinate that I ended up using anything and everything I had in the garden because I didnâÂÂt think that it was going to work, but it has done. I do by the way live on the South coast of Spain so do have a small advantage. My advice would be try it, all you would be wasting would be your own time, and when the effort works you will glad that you did. Fruit or no fruit.
I am currently sprouting wild tangerine seeds. My grandfather had a lemon that died back in the early 80's. It came back from the rootstock as a wild tangerine. Since then about 10 more have popped up in the yard (mainly because as kids we had tangerine wars around the property. Each bore fruit within two years and each had wonderfully sweet fruit. Hopefully I will get the same result.
Lettuce does best in the spring, how close is your house to providing spring like conditions? Cool moist temperatures with lots of sunshine provides the rapid growth for lettuce. Difficult to provide indoors, but any leaf lettuce would do as well. Al
We grew it inside last year, too. The lettuce was tender & tasty cut as baby lettuce several times. We reused the clear container from purchased lettuce as described in the link. It was easy to harvest with scissors & very clean!
lights: just put it on top of stove to use the range hood CFL (stacked containers to adjust height) It was easy to adjust height of containers to keep leaves close to bulb. My family adapted well to the routine to remove it during the day & return for bright light at night.
Grew lanky still, so our method isn't perfected. I think it may have needed a liquid fertilizer more often. Since it was in clear sight it didn't get a chance to dry out.
Here are my notes from the article I've put in the link.
Lettuce Inside Notes:
Lettuce grows best indoors when the temperature is between 40 and 65 degrees and when it receives 6 to 10 hours of bright sunlight daily. Consider purchasing lights designed specifically for plant growing if your room does not receive sufficient light. Select a container at least 10 to 12 inches deep to accommodate deep roots.
soil:
Mix equal parts potting soil, vermiculite, peat and perlite and place into your container. Place your lettuce seeds in 1/8-inch deep and cover with soil mixture. Add water until the soil is soaked.
thinning:
Germination should take place after one to two weeks, at which time you will need to thin your lettuce to give it enough room to grow. You will need to remove extra seedlings so there is one seedling every 6 inches
watering & fertilizing (I would use worm or compost tea)
Add a mixture of balanced fertilizer that is equal parts nitrogen, phosphorus and potassium every two weeks.
Water the lettuce as often as necessary to keep the soil moist without being fully wet.
harvesting:
when leaves large enough to pull away or use scissors to cut & it will grow again

Your lights must be close to the plants. To do it well you will need 4 bulbs side by side for one flat. However if you used 4 bulbs you could do 3 flats. The end of your flats need to hang over the flat a few inches. You will not burn your tomatoes with grow lights. You can germinate with cool white lights. I think the other trick is to time it just right so that they don't out grow the amount of light you'll need for them to be surrounded efficiently. You will need to transplant also which means you must prepare to have more lights as they grow or just start smaller. How many flats do you plan on sowing?
It is my opinion to use smaller containers to start seeds in so your seeds wont rot. It gets to me a juggling act too to keep them at just the proper dampness. Use a spray bottle to mist them frequently on top. You don't want the mmedium soaked. Be sure to use those doam lids as they hold in the right amount of moisture.
If you haven't invested in heating mats it would be an excellent investment, trippling your germination rate. They are inexpensive if all you want to do is increase the ambient (surrounding temperature in the room) up 10-15 degrees. Once your seedlings germinate you're done with the mats. I'd be careful using bottom watering until you at least have germination and becareful not to over water.
You can also make a tent to keep the right moisture in the rooms. At this time is is of the utmost importance that you do not let the top of the seedling medium dry out or the seeds may be cooked. You must check them once or twice a day. take off the domes and give them a good mist. You can get hydrolic misters for 6 bucks at Walmart but I doubt they are in stock, just get a good spray bottle. Too much water is another major culprit for leggy tomatoes. My suggestion is to sow about as half as many seeds as you have lights for now because once you start transplanting your seedlings will take up twice the amount of space.
Another trick is to transplant a tomato plant deeper than it was grown, this goes for anything transplanted for the most part. Always pot up one size larger. It is important the plants do not sit in mushy medium. You may also pinch off a couple new leaves, this also helps to bush the plant out. I'd wait a little while though. Also don't over plant, or if you do get rid of the weaker ones early enough they are not affecting the nearby ones. Instead of pulling them out snip them off so as not to disturb the soil. I would also start fertilizing a weak solution. Look into what is best at this time. Be careful of not too my nitrogen so you don't get a lot of green but not fruit. (Research the best fertilizer for tomatoes sprouts. Some are for healthy root development, which maybe you want now. Whatever you choose dilute the solution about 1/4 and give it to them every time. the bottom watering suggestion is good but keep the mats handy incase your medium gets water logged and you have to evaporate the water fast. I prefer a heavy mist until I have reason to believe roots are extablishing.
I've grown many things in the basement, many heirloom tomatoes, so good luck, I'd get grow bulbs with the whole spectrum of lights, but cool white will germinate the seedlings due to the plants don't need light to germ but heat. Good luck, hope this has been helpful,

Of course harden off your seedlingsusing your coldframe. I'd love to make a coldframe. Yours sound like the ritz. Have you considered Winter Sowing your seeds? the benefit to that is your seedlings will be stronger and heartier. Here's a link you might be interested in. I'm sure your cold frame would be put to much good use, and you'd eliminate the problem of the seedlings being spindly. Winter sown tomatoes don't germinate as fast but because they have been grown with Ma Nature they are much hardier and catch up to their counterparts,
Let me know what you think,

Hello neighbor! Is this your first time starting toms from seeds? I've started a few, and here's what I've found, especially for our neck of the woods.
I would wait until at least April to start any seeds. I had the same idea you had and started last week of March my first time and they grew WAY too big to have inside the house. Once they germinate, they grow very quickly. Mine got huge without being under lights towards the last 3 weeks because they were too tall for my shelf. I stuck them in my 3 season porch and they continued to grow until the last weeks of May when they went out, at almost 2' tall!
I suggest starting no earlier than mid April, since even if you have lights, they still get leggy because they are such sun lovers. Also, toms don't do well with nighttime temps less than 50F, so in my area outside of Boston, that still means I don't set them out permanently until Memorial Day, hence the mid April sowing. They take 4-6 weeks to be ready for transplant.
I did not use a heating mat to start the seeds; just sow and they came up inside my dining room, which is around 67F. Kept them moist with some plastic shrink wrap over the top and took the cover off as soon as there was a sprout. Just watered from the top when the soil dried out some. I did however grew them in potting soil, not seed starter mix, and there was no shock from transplant. Since there was slow release fertilizer already in the mix, I didn't do any fertilizing until they were outside. I also plucked off the bottom 2 leaves when I transplanted from a 3" pot to a 6" pot, and then again when they went out to their final containers. I started the seeds in the 3" pots. Since I had them out on the porch and in the sun during the warmer days of May, that hardened them off for me.
Oh, and drainage, drainage, drainage! Make sure you at least add some more perlite to the mix you buy or mix so they aren't standing in water. Keeping moist in one thing, too wet is another.
Good luck with your upcoming tomato jungle!
You don't say where you had the young roses, what kind of conditions they were exposed to. Some generalities:
Don't overfeed, forced new growth will be more susceptible to diseases. Good air circulation will help. Water early in the morning but only as needed, and if you don't have all day sun for them - place them where they will get morning sun so the foliage is dry from night air as early as possible.
There's a chance you did nothing wrong. Your roses from seed if taken from a hybrid plant or cross pollinated could have just had dominant bad genes and were destined to be disease prone - there is always that chance when growing them from seed that you will need to choose the healthiest and best looking from the lot and discard others.
Depends on wehat seeds you have--see chart at site linked below.
You can Google "seed viability chart" --add either flower or vegetable aas the first word if you want. There is a LOT of info out there.
You can always do a germination test, too, using damp paper towels-- if you have enough to spare of the seed you are testing.
Every few years or so I take all my old leftover flower seed to a back corner of the yard -- where I had had a compost pile, say, so there is bare ground -- and just scatter all the contents of the packets around to see what comes up!

I grew guava seeds that you get from the store, as well as those black sesame seeds, they sprouted but died from my own hand. I also sprouted date seeds, they take years to get any appreciable size, fyi. I also sprouted kiwi seeds from the store, they are best sprouted fresh. I also grew ginger like you but I always seem to either neglect it or it dies when winter comes. Horseradish grows easily! Also, I got organic wild rice and that came up nicely.
BTW, I wouldn't harvest wild plants unless either you know they aren't rare/endangered or it's in a place that will be slated for 'development'. Also don't do it in a nature reserve or gamelands, they'll fine you bocu bucks if they catch you.
Well that is a good run for a thread huh? I have tiny tiny delicate poppy seedlings growing in the window sill. The first bunch got dried out and died so I have a sandwich bag over the pot to keep these from drying out.
They are different from the poppies grown for their flowers. These look like tiny bean sprouts whereas the other kind looks like lettuce to me. I threw a whole bottle from the cupboard in the garden early last fall. Maybe something will grow in the spring.
I have grown dill but the flowers were more green than yellow. I got a very interesting caterpillar eating away at them. I have never seen one like that. A visit from him was worth the green flowers! I grew ginger and got lots more ginger but no flowers.
I have a lemon tree growing that came from a slice in my Vodka Tonic. I gave up the Vodka but the tree is now almost four feet tall (indoors of course).
The only thing I harvested from the wild was pretty weeds. One of which still comes back every year. I don't know what they are called but they are everywhere. It�s not like I was hauling away trees or something! LOL
jimigunne,
Mesh size is the number of openings per inch of the mesh; so #10 mesh would be very small openings. To come up with the actual size of the openings, you'd need to know the thickness of the wires that make up the mesh. There are about 25 mm in one inch, so for example if the wire thickness would take up about 5mm, you would need #4 mesh to get 5mm openings. You might be able to find galvanized hardware cloth that would be very close, but coming up with exact 5mm openings will probably not be easy :-)

Thanks again. I planted the seeds in a planter with a wide rim, and filled it with soil about an inch below the top of the pot, to avoid the seeds blowing away. I spread them on the soil, lightly pushed them in, and then watered with a spray bottle.
Trouble is, I can't even see them now. I have no idea whether they've blown away or not :P.
Anyway, should I continue to water using a spray bottle once or twice a day or is it acceptable to expose the seeds to rain?
Thanks again
I started another batch with soiless mix filled to the top. All of them (collards, bok choi, endive, escarole...etc) just started to develop the first true leaf, but one of the mustard green's cotyledon is still yellowish and dying. Its always the mustard greens looking very bad...?
I was going to plant fewer pots at first, but every one of the seeds germinated so I decided to plant them all but didn't made enough mix. So all the pots were half filled (2 inches deep)...I thought they would do OK until transplant.
I got seeds too for this season, luckily they germinated on me or these seeds are just easy to germinate no matter what?
I'm new to seed propagation, so i tried Coleus seeds indoors. The packet said, about 85% germinated. I got a seed flat of 72 cell packs, and I think I have about 100% of the seed germinated, some pack is so crowded. I am just amaze, it germinated in 10 days. I am just waiting if some of them will survive to become baby plant or die off on me. Most of them has just the first 2 green leafs.

Surface sow (some light may be beneficial to germination), takes 2 - 3 weeks to germinate at 65F.
These are dwarf, you'll want them near the front with their short height, in sun. As with many alpine plants, they could be short lived perennials or could behave as annuals or biennials in your warmer humid climate but should self sow if you don't deadhead.
You could direct sow, I generally do with poppies - if you have a place prepared for the plants you could sow some now, or wait and put all of the seeds out in late winter/early Spring.....Fall or Spring is the suggested time for direct sowing - doing both may give you a longer succession of blooms.
I grow Lupin every year and have not noted the problem you are having. For me there has never been anything difficult with starting Lupin from seeds, my own saved or purchased. For purchased seed I always soak in hot water first, for my own fresh seed this is not necessary. Al
I grew all my plants via winter sowing--set the seed in a recycled milk jug with plenty of moist growers mix, stick in a label, tape the jug shut and set it out in the cold. Seeds will germinate around mid-March; plants will bloom second year. None of my winter sown lupines lost their true leaves after planting out or potting up except when they went dormant for the cold weather.
