Starting Seeds Indoors

Well, the dark days of winter are upon us and the garden is probably looking a little bleak. We are all basking in the few hours of sunlight we are getting, like lizards trying to energize for the day. While there isn’t a lot to do in the garden right now, you can start thinking about what to plant for spring and it’s almost time to start your seeds indoors for transplanting in spring. Here are a few tips and tricks to help you be more successful.
#1 Get Fresh Seeds
TGO carries a number of different seed lines and tries to offer Austin’s best seed selection. A little research before hand is a great thing. Don’t buy a paste tomato if you want a slicing fruit, etc… Sometimes a large selection is a great thing, sometimes it’s a bit overwhelming.
#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 is recommended. Avoid mixes that have a high fertilizer content, as this causes more problems than good. TGO carries a couple of special seed starting mixes, plus our own TGO brand of potting soil is coir based, and coir is an excellent medium for seed starting.
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. TGO has these and other options for sale in our tool room.
#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, which is March 15th for Austin. Many people will place plants out earlier, but one good freeze and any lack of protection will kill a young plant easily.
#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. Special heat mats for seed germination are available at TGO and really help get seeds going quickly. This may the best tip you can take away from this article.
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. Other plants may be a little slower or faster to germinate, but a week or two is nearly universal.
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. The “Jump Start” light system we sell at TGO is a great solution if a good window is not available. 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 (tomatoes only).
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 (tomatoes only) , 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.

Fruit trees for Austin

Fall / winter is the time to plant temperate fruit trees and we’ve got a great selection right now. We do a great deal of research to get varieties that will work well here in central Texas with little maintenance. So, let’s take a quick look at these fruit trees and cover a few basics you’ll need to know before planting.
First, a temperate fruit tree is a tree that will do fine outdoors, in the ground, in our weather conditions. The alternative would be tropical and sub-tropical fruit trees, like avocado, mango, and even citrus. These trees can be damaged or even killed by hard winter freezes, depending on the variety. The rule of thumb here in central Texas for temperate trees is the “P” fruits: peaches, pears, plums, persimmons, pomegranate, and phig (OK, so it’s really fig, but I needed it to work). We are also trying a few types of apples this year, although reports of their success seem to be mixed.
Second, be sure you have the room and conditions necessary to grow a fruit tree. While I encourage pruning trees to a size that is “reachable” for you, they will still need at least 8’-10’ of space away from a building or other trees and AT LEAST 5 hours of direct sun for good production. Full sun all day is fine for all these trees and will lead to better production.
Next, it’s time to choose a tree. Now, I have listed several types of fruit above, but all peaches (or pears, or plums, etc…) are not created equally. Many of the temperate fruits require a certain number of chill hours to produce fruit. Chill hours are the number of hours below 45 degrees between October and February. We strive to carry only low chill hour fruits, as we can often have very mild winters and hence, few chill hours. Even with the attempts we make, some winters are just too mild for good production. The Austin area averages about 700 chill hours a winter, but this can be extremely variable. All the good, independent garden centers in town do their research. Box stores likely do not.
Last, here are a few other tidbits of info you will need to know when choosing a fruit tree. All fruit trees will produce best if they have a cross-pollinator nearby, but some varieties require it. Peach, pomegranate, fig, persimmon, and some plums can be self-fruitful. Pears, apples, and most plums need another tree nearby to produce a good crop. This means room for not one, but two trees. Also, be sure to look at the characteristics of the specific variety you are looking at. Do you want a freestone or clingstone peach? Do you plan on cooking with your pears or eating them fresh? Do you prefer an astringent or non-astringent persimmon? One of our plant consultants will be glad to help you answer these questions and find the variety that is best for you.
So, plant a fruit tree or two this winter and be rewarded with a bumper crop of fresh fruit for years to follow.

Attack of the Aphids!!!

Something wicked has been awakened by the recent rain and cool weather. In all my years in the garden business, I have never seen an explosion of aphids like we’ve seen in the last couple of weeks. Just the other day, I saw several free flying aphids in the middle of a parking lot. I was at least 50 feet from any plant, surrounded by asphalt.

So what can we do about these critters that have suddenly left everything sticky and covered in sooty mold? To start, keep an eye out for the source of the sap. In my yard, it is my pecan trees. I can park a freshly washed car in the drive and within two hours, it is covered in a sticky film. Unfortunately, there isn’t much you can practically do about large trees like this. Just keep an eye on any understory plants. Be sure the aphids are not spreading to these plants and keep an eye out for sooty mold (more on that in a minute). If the aphids are on lower plants, small trees, shrubs, and perennials, you can treat them in several very effective ways.

One of the first ways to go after the aphids is simply to blast them with high pressure water. Products such as the Bug Blaster help to create a spray that is strong enough to remove the bugs but not enough to hurt plants. This is always my first line of defense. If blasting doesn’t seem to be effective, there are a number of great organic products that are very effective on aphids. Insecticidal soap is by far the safest product you can use. It is a very simple soap that is very harmless to people, plants, and animals. Another product I really like is Orange Oil. It is a natural insecticide, miticide, and fungicide. It works really well on aphids and many other insects, but a little care needs to be take when it is used. Never spray an oil in the middle of a sunny day. Be careful of plants in the mint family, including all the salivas, as they will not tolerate oils. If in doubt, test your plant before covering with oil.

Not only will the soap or Orange Oil kill the aphids, they both help to break down the sooty mold. You see, many insects (aphids, scale, mealy bugs) suck chlorophyll from plants. Chlorophyll is a complex sugar made by the plant. Their simple digestive system processes these sugars a little, but what they secrete is basically sugar water called Honey Dew. When Honey Dew accumulates on a surface, especially plant leaves, it can begin to mold. It will turn black and become what is known as Sooty Mold. Enough Sooty Mold on a plant can great hinder that plant’s ability to do photosynthesis and continue to prosper.

Also, before spraying, look for beneficial insects that may already be doing your job for you. There are pictures above of both ladybug larvae and green lacewings. These are both voracious aphid eaters and we would highly encourage you to leave them and let nature take care of the invasion.

It's Corn Gluten Time!!!

Corn Gluten is an excellent, natural way to control (notice I didn't say eliminate) weeds in the lawn. It is usually applied 2 times a year. A September/October application is done to control the early spring weeds that pop up in late February. In February/March another application is done to control the summer weeds. It is in stock now and ready to be applied.

THNAK YOU AUSTIN!!!

Thanks to all of you that voted Great Outdoors as Best Garden Center in the Chronicles Best of '09. We are very flattered and hope to continue doing what we've done to be the best.

A must see film.

I just watched the film "The Future of Food" on hulu.com and had my mind blown. It is a very disturbing look at the giant industrial farming "machine" and how it has effected our food, farmers, and economy. WARNING!!! It is not for the faint of heart. It will really kinda scare you into thinking harder about the food you eat and where it comes from. It really looks at genetically modified food and what has gone on in that industry.

It also reaffirmed what I have known for years. Monsanto is a very, very bad company. Do not buy anything from them, which will take some research. They have their claws in a lot of aspects of our lives.

Gardens at Rancho Pollo nearing completion.

Well, after several months of weed / grass removal, soil amendment, planning and planting, the garden at my home, Rancho Pollo, is nearly complete. Things still look a little small, as some of these plants are pretty rare and hard to get in a large size. I know that in a couple of years, it will be spectacular. Spreading the 11 cubic yards of DeCoG was the last task and it was finished on Wednesday. Look for pictures coming soon.
