Tomato seeds not germinating
Try as I might, and unlike Monty Don, I am unable to get my ''Gardener's
Delight' tomato seeds to germinate. Should tomato seeds be germinated in the dark or the light? May 1st. now and I'm fast running out of patience. MikeCT |

Tomato seeds not germinating
Mine were germinated in the light. Seem to have grown ok but they did take
a fair while to germinate for me. Donna "MikeCT" wrote in message ... Try as I might, and unlike Monty Don, I am unable to get my ''Gardener's Delight' tomato seeds to germinate. Should tomato seeds be germinated in the dark or the light? May 1st. now and I'm fast running out of patience. MikeCT |

Tomato seeds not germinating
Hello Mike,
They should germinate easily in 7 to 10 days in a small pot on a warm windowsill or conservatory, just slightly covered in compost and kept damp - ideally with a plastic cover or bag over the top. Old seed can take longer or not germinate at all. The only alternative at this time of year is to buy small plants - cost more but at least you wont waste any more time and will have back up if the seeds you have really are duds. Hope this helps............good luck Alan "MikeCT" wrote in message ... Try as I might, and unlike Monty Don, I am unable to get my ''Gardener's Delight' tomato seeds to germinate.

MikeCT We've just got back to Normandy from a week in England and came back armed with a Gardener's World. The free chives and lettuce seeds packets had a good quantity of seeds, but on opened the tomato seed packed it was disappointing to find only 8 seeds. While filling a small trough with compost a sudden gust of wind blew the opened seed packet away! There were only 2 seeds left tucked into a corner! I promise never to complain again - honest! I'll have to look out for stray tomato plants growing on the gravel drive now! -- David .... Email address on website http://www.avisoft.co.uk |

Today three weeks on, the ones in the garden have still not germinated, the ones in the seed tray are big enough to transplant. John. |

Tomato seeds not germinating
How do I start tomatoes from seed?
#1 Get Fresh Seeds For the best chances of success, acquire your seeds from reputable commercial sources. As tomato seeds age, their germination rate decreases. It is best to use seed that is less than 4 years old; however, seed that is much older can usually be germinated if has been stored in cool and dry conditions. #2 Get a Seed Starting Mix Garden soil is not a good choice, as it compacts too easily and can harbor organisms that cause diseases. A commercially prepared seed starting mix, usually a combination of peat moss, vermiculite and perlite, is recommended. Avoid mixes that have a high fertilizer content, as this causes more problems than good. Commonly used and recommended mixes are Jiffy Mix, ProMix, MetroMix and Fafard. Many other brands, or even homemade mixes, can be used. Combine the seed starting mix thoroughly with warm water to bring it to a useable state. This may take quite a lot of mixing, as completely dry mixes can be difficult to wet. Sometimes it's best to let the moistened mix sit overnight to be sure that it is evenly wet. The final mix should be damp like a wrung-out sponge, not soaked or soggy. #3 Select Some Containers Tomato seeds will germinate in anything as long as the seeds get moisture and warmth. After germination and initial growth, the seedlings need to be potted up to larger containers. Containers must be able to drain excess water. If using old or previously used containers, its best to sterilize them with a 10% bleach solution. Your choice of containers for potting up depends on the number of plants you desire. Professional nurseries use growing "flats" with various-sized plastic cell inserts. Many sizes and kinds of flats are commercially available to the home grower, but they are not essential. Many home growers use styrofoam or plastic drinking cups with holes poked in the bottom. Just about anything will work as long as excess water can drain. #4 Determine When to Start Many novices fail at starting tomatoes simply because they start too early. Given the proper care, full-sized tomato transplants can be grown in 6 to 8 weeks. Before planting seeds, you must determine when your plants can be safely placed into the garden. Planting outdoors is best done about 1 or 2 weeks after the average last frost date for your area. Ask friends or use web resources to find your average last frost date, then do the math to calculate your seed starting date. #5 Plant Your Seeds Fill a small container with damp seed starting mix. Plant your seeds about 1/8 inch (3 mm) deep. Firm the mix lightly to ensure that the seed is in direct contact with the moist mix. The seed needs to absorb moisture during the germination process. You can plant lots of seeds close together because the resulting seedlings will be moved to larger containers after germination (when the first true leaves appear). It is a good idea to provide some sort of covering over your germination containers to preserve moisture. You can place the container in a plastic bag or cover it with a sheet of plastic. Allow for some air to circulate but don't let the mix dry out. Dry seeds will not germinate. #6 Patiently Wait for Germination Place the germination container in a warm location out of direct sunlight. Light is not needed during the germination process, but will not be harmful as long as high temperatures are avoided. Tomato seeds usually germinate within 5 to 10 days when kept in the optimum temperature range of 70 to 80F (21 to 27C). Germination is delayed by lower temperatures and accelerated by higher temperatures. Temperatures below 50F (10C) or above 95F (35C) are detrimental to germination. Keep a close eye on the first seedlings, as they need to be moved into bright light as soon as they emerge from the soil. They will explosively reach for light, and if the light is not adequate, you will get 3-inch-long (8 cm long) stems shortly after germination - this is very undesirable. If this occurs, you could try to transplant to a deeper container, or you may want to start over. #7 Put the Seedlings under Light Very strong light is needed to support tomato growth. A heated greenhouse is the ultimate location to continue growing your seedlings. A second choice would be a cold frame (possibly with supplemental heat for cool nights). Many home growers use inexpensive fluorescent shop lights. A south-facing windowsill can work but usually presents more problems than the fluorescent shop light setup. If fluorescent shop lights are used, the leaves of the plants must be within inches of the bulbs. Use your own creativity to make a setup that gets the plants directly under the bulbs. The lights should remain on for 16 to 18 hours per day. #8 Monitor the Plants as They Grow On Tomato seedlings grow best at a temperature of about 65F (18C) with some air circulation and lots of light. When watering, most growers soak the mix and then let it get nearly dry before providing more water. When the plants develop their first true leaves, they should be transplanted into larger individual containers. The plants actually benefit from this re-potting step, as it helps them develop a strong root system. The plants may be set deeply into their new containers to shorten the height of the seedling. Most commercial seed starting mixtures have a small amount of fertilizer that will support small seedlings for some time. Depending on the components of your starting mix, you may need to begin fertilizing. If you do fertilize, do it very, very sparingly with a weak dilution. Depending on the size of your containers and your growing conditions, you may need to pot up a second or third time to prevent your plants from becoming rootbound. The plants require good lighting to continue to grow well. Place the plants where they get plenty of sunlight, and if that is not possible or adequate, use fluorescent fixtures, or specialized high-intensity grow lamps, or use a combination of natural and artificial lighting. Keeping large tomato plants indoors, under artifical lighting, can be quite difficult. To avoid problems, don't start too early. The best solution to the lighting dilemma is to plan your seed starting date so that the transplants reach a reasonable size along with the arrival of suitable outdoor temperatures. #9 Harden Off your Transplants Introduce the plants to outdoor conditions slowly. This is called "hardening off". If it is not done slowly your plants may be shocked and their growth may temporarily cease. The longer the plants remains indoors, the harder it will be to acclimate them to the outdoors. Avoid full sun and wind when you first move them outside. Cold frames can be used to harden off the plants. The covers can remain in place on inclement days and removed on moderate days. Temporary structures can be built from plastic sheeting. Buildings and fences can be used to provide sun and wind protection while the plants adapt to outside conditions. If really cold weather is forecast 40F (4C), it is best to bring the plants back inside. Freezing temperatures will destroy your plants (and it happens fast). After the transplants are hardened off, they can be planted to their final outdoor growing locations either in the garden or in large growing containers. Most agree that any early blossoms should be plucked off prior to transplanting. Others leave the early blossoms in place, especially if the transplant is strong, healthy, and not rootbound. Common Problems Leggy Seedlings The plants can become "leggy," the stems being elongated and limp, and the foliage sparse. Leggy seedlings usually occur due to insufficient lighting, too much heat, or too much fertilizer. Suggested remedies, short of starting over, are to repot the plants deeper as described earlier in Step #8, and to use a fan to improve air circulation and keep temperatures moderated, resulting in stockier and stronger plants. Damping Off Characterized by lack of germination (pre-emergent) or causes narrowing of the newly emerged stems at the soil line and the tiny seedlings then flop over and die (post-emergent). Various fungi are responsible for the condition and they are found in high concentrations in any mix with real soil. That's why it's best to use the artificial seed starting mixes mentioned in step #2. Also, it's very important to be sure that plastic domes or baggies on your containers are not airtight. If these precautions are observed, it is unlikely that you will experience damping off. Slow Growth When seedlings refuse to grow it is usually because the temperature is too low or the nutrient level is insufficient. Stuck Leaves Sometimes the cotyledons (the first leaves formed from the seed) have trouble getting loose from the seed coating. Be patient, as the leaves will usually escape. You could wet the seed coating, or you could try to carefully pinch off the seed coat, but if you pinch off the cotyledons, the seedling will likely die. A simple way to wet the seedlings is with a spray bottle of water set to mist. A small drop of saliva is also very effective at loosening seedcoats. Over-watering Many growers fail with tomato plants because they over-water. Soggy soil will cause seed to rot. Once the seedlings are growing, they should be watered thoroughly then left un-watered until they are almost ready to wilt. Over-fertilizing Overfertilizing can cause seedlings to die, to stop growing, or to grow rapidly into spindly plants. One or at most 2 applications of very dilute fertilizer are adequate to get a seedling through to transplant size. -- Baal I smile and go off waving (Amiably) - for that's my way "MikeCT" wrote in message ...

May 1st. now and I'm fast running out of patience. MikeCT Chit them between two small sheets of moist kitchen towel or four folded sheets of thick toilet paper. Moisten but don't saturate the paper with a fine mist of luke-warm water from a plant sprayer. Lay the seeds out on the paper. I make pairs of "slides" using the lids of margarine tubs - held together with elastic bands and put the folded paper cut to size inside those, and open up and inspect them daily. They can also be remoistened if necessary. They can be left almost anywhere within reason - and light or dark - clear or coloured lids doesn't seem to make any difference. After a few days the small while radicle root will appear from the pointed end of the seeds. Remove seeds as they sprout and "plant" them rot end down into pots of compost. Or trays to suit. Make a slit in the compost and push the seed into one side and the firm it up all round rather than pushing it in directly as the root is brittle and may break off. The only extra equipment you may need are a pair of tweezers for handling the seeds. I got into the habit of chitting almost everything except carrots, brassicas, lettuce, cacti etc ( even leeks and onions ) on account of being short of room for pots on the windowsill and the cost of some f1 hybrid, seed years ago. And have never gone back. There's far less waste of seed, far fewer variables and far fewer things to go wrong. michael adams .... |

Sprinkle on the seed. Put a fine covering of vermiculite on top. Place in the smallest cheapest electric proporgator you can get. Works every time. Hope this helps. Scouse |

May 1st. now and I'm fast running out of patience. I now germinate all my seeds with 100% success with a mix of JI seeds compost mixed in with perlite (not vermiculite as I keep saying when I talk about it). All my seeds are under propagators, no heat, just a plastic cover and if I have pots I use plastic bags to make a little propagator. I now have all type of propagator, from the one with a little fleece at the bottom, the polysterene ones and the simple black tray with a clear lid. All seeds need air via good drainage, light, warmth and a light compost. Once watered the condensation will keep the environment in the propagator moist. There is nothing that can go wrong in this way - there's no chance for the seeds to fail. The only thing is that if you water too much you'll create a fungi and your seedlings will die. I used to put everything on window seals (I don't have a greenhouse) and turn the tray/pots around to stop the seedling bending, watering them often and one simply hasn't enough window seals ... I would very much recommend the way above. It saves time, money and most of all disapointment. |
