The Best Heirloom Tomato Growing Tips
Heirloom Tomato Growing Tips
in Gardening Advice /by Stephen Scott
The yearly gardening season is just about on us and for many gardeners that means a heavy focus on tomatoes. Specifically, heirloom tomatoes, as their meteoric rise in popularity over the past few years would have many a pop and rock star green with jealous envy. The heirloom tomato seems to be almost everywhere these days, from high end cooking shows with their ultra-close-ups and glamor shots to many new cookbooks focusing on home-grown and locally sourced produce to Farmer's markets, CSA's and almost everyone's home garden. Even die hard hybrid "Better Boy" and "Early Girl" gardeners that have planted nothing else for years are giving these wondrous beauties a shot.
With all of this attention being paid to the "Love Apple" as it was known in Colonial times, we wanted to give you a better chance of harvesting all of that potentially rich, complex, juicy tomatoey goodness that are only seedlings at this point.
Tomatoes are complex creatures, needing rich and well mineralized soil that is well drained and not over-watered. The simple, ruinous yet well intentioned act of giving tomatoes too much water most likely accounts for fully 75% of all of the problems with them; from soil borne fungi and other micro-organisms attacking the roots to fruit splitting, cracking and blossom end rot and ultimately the worst- flavor wash-out. Ideally, tomatoes like a lightly moist soil. The best way to judge when to water is by getting to know your plants and paying attention to the leaves. When the leaves just start to curl at the very edges or tips is when the plant is telling you it's thirsty. Different varieties of tomatoes will have naturally curling leaves, thus the need to get to know your specific plants. Give them a drink, but don't drown them. There has been multiple studies done that have clearly shown that tomatoes do much better with a little less water than a little more. Production, taste and disease resistance all increase when the plant is watered a full 25% less than what is commonly believed to be the "right" amount.
Now that we have the biggest issue out of the way, let's look at some other techniques to get the best out of this year's tomatoes! This is not an exhaustive, encyclopedic resource. There are many, many books available that are devoted entirely to the subject of fixing your tomatoes. What we want to do is give you some good, proven and easily used tools to help you get the best out of your tomatoes this year. Some of the most effective remedies are the simple and easily applied ones, as they are the ones that get used more often. So here we go!
-If you see brown or black soft spots appearing at the blossom end (opposite the stem) of the tomatoes, you have blossom end rot. This is caused by a lack of available calcium and can be easily corrected. Tuck a Tums or other antacid tablet or two into the base of the roots and give them a little water to soften. The antacids are calcium carbonate and will quickly provide needed calcium to the plant. It won't cure the existing blossom end rot- nothing can- but will prevent the next set of blossoms from having then same problems.
-A 10 – 20% milk solution used as a foliar spray is highly effective against mildews and tomato mosaic virus. This remedy was discovered by Wagner Bettiol, an agronomist from Brazil found that weekly sprays of a milk solution was faster and more effective than synthetic chemical fungicides. The milk solution controlled the fungi just as well, with the added benefit that it acted as a foliar fertilizer and boosted the plant's immune system and production. This spray also works for zucchini, cucumbers and other cucurbits including melons. It seems to work on roses also!
1 Cup milk
9 Cups water
Mix well and spray on offending mildews, blights and assorted unwanted fungi.
-The baking soda/mineral oil approach has been around a long time and is familiar to long-time gardeners, but it bears sharing. Cornell University has research showing the effectiveness of this approach. The baking soda deters fungus spores, and the oil coats the leaves, holding the baking soda in place longer.
1 Tbs Canola or mineral oil
1 Tsp baking soda
1 Gal water
Mix well and spray directly on the fungal blights.
– To stop nematodes from attacking the roots of your tomato, insert old 1 to 5 gallon nursery pots that have been cleaned, disinfected and had the bottoms cut out into the soil leaving 2-3 inches showing. Transplant your tomatoes into these guards. For heirloom tomatoes, the larger the pots the better, as the root system can be extensive.
-Another preventative measure for blight and other diseases, sprinkle a handful of this mix into the planting hole before you insert the transplant.
3 Cups well aged compost or potting soil
1/2 Cup powdered milk
1/2 Cup Epsom salts
1 Tbs baking soda
Mix well and sprinkle a handful into each planting hole.
-For soft-bodied insects, the milk spray described above is very effective, as well as a simple home-made insecticidal soap spray. You must use soap and not a detergent. They are different in how they work. Soap will kill the bugs, detergent will often kill the bugs and your plants! You've been warned. One of the absolute best soaps out there is Dr. Bronner's. You can get it in a liquid form, it is certified organic and won't harm your plants.
1 Tsp liquid soap
1 Qt water
Mix well and spray on the unwanted critters.
-When the plants are really working setting flowers and fruit, use the Spring Garden Soil Elixir recipe and omit the Borax and cranberry juice. Mix as usual and give a light spray to the roots as a side dressing to give the tomatoes a boost in nutrients to keep the health and flavor up.
These techniques and tips will set you on the path of better, tastier and longer producing tomatoes this season. If you have an especially effective remedy or recipe that you've used to help your tomatoes do well, please share it with us!

Growing Peppers 101
in Gardening Advice /by Stephen Scott
The More You Know – the Better You Grow
Growing peppers seems to come naturally for some gardeners, while others always seem to struggle. Sometimes this stems from easily-avoided mistakes or accepting certain myths or misinformation as correct.
Today we're looking at the basics of growing peppers in your home garden and some mistakes and myths to be aware of and avoid. You might look at this as a how-not-to guide because occasionally it's just easier showing what not to do than describing and explaining the right way. Plus, seeing other's mistakes sometimes sinks in faster.
These are our observations from our 20+ years of gardening combined with the past 10 years of gardening questions we've answered.
Conditions
The initial conditions you choose are critical to sprouting, transplanting and growing success, no matter what seed you are planting. Here are some things to consider as you grow your peppers this season.
Starting Seeds
•Pepper seed germination – even under optimum conditions – is often slow and erratic. Don't compare your tomato seed germination with peppers and think they aren't performing as they should.
•Tomatoes can sprout in 3 – 5 days in ideal conditions, while peppers might take 14 to 21 days. This is normal, be patient, and don't worry!
•The two most common problems in pepper seed germination for home gardeners is soil that is too cool and not moist enough.
•Use any readily available thermometer that will accurately read in the 60° to 100°F range and insert it an inch into the soil. If it's 80° or above, you should have good success. Soil temperature below 75° can delay seed germination by 3 weeks or more! •An easy way to determine soil moisture is by touching the surface of the soil with your finger – it should be damp to slightly wet where you touched the soil, and you can feel the moisture when you rub your fingers together. If not, it's a little too dry.
•A good rule of thumb for germinating pepper seeds is warm, moist soil – meaning 80° – 90°F – watered from above with warm water.
•This will consistently give you better germination on all pepper seeds – sweet or hot. Maintain the soil temperature with heat mats or placing the seedling flats in a consistently warm area such as on top of a freezer or refrigerator. Warm water from above minimizes the cooling effect on the soil as opposed to bottom watering during sprouting. Once the seedlings have sprouted, switch to bottom watering to minimize mold and fungus issues.
Transplanting
•Young seedlings need to be conditioned or prepared for the outside garden environment, or they will suffer greatly or die. Seedlings are tender with soft tissues, sensitive leaves, and small root systems. They aren't ready to be plopped into the early spring garden without hardening off, sort of like a boot camp or physical conditioning program. This usually takes about 2 weeks of setting the seedlings outside for short periods and going longer as they toughen up.
•The ideal transplanting day is warm soil with cloud cover and little to no breeze. Seedlings need warm and moist soil, much like they have before transplanting. Give them a drink of water immediately after transplanting to help avoid shock.
•The biggest issues with transplanting are soil that is too cold, too dry (or too wet) or the seedlings are still too tender and need more hardening off. It's better to wait a few days to a week than jump the gun, transplant too early and lose your hard work.
•Peppers like to be close, but not too close. 18 inch spacing between plants is a good start – smaller plants can be planted a foot apart, while larger ones will need 18-24 inches. You want the plants to grow a good leaf canopy that shades the fruit from sunscald while not competing with each other and becoming leggy or spindly.
Growing
•To keep your sweet peppers sweet, don't plant them close to your hot ones; they will readily cross-pollinate and you'll have extremely hot sweet peppers! We learned this one summer when we had Jalapenos upwind of our bell peppers. The unexpected bite of a fiery bell shocked us; we later taste-tested and found the bell peppers were hotter than the Jalapenos.
•Giving your peppers some space is the best solution – distance minimizes the chance of hot pepper pollen finding your sweet pepper's flower, either by wind or pollinators. Seed growers isolate peppers by 1,500 feet, but if we've found planting sweets 50 feet or more upwind of the prevailing breeze is pretty dependable. Peppers also grow well in containers or large pots, so you can grow them well away from the garden if needed.
•Peppers produce best with moderate temperatures, although they can tolerate warmer days if it cools off at night.
•Much like tomatoes, the key to getting big harvests is night-time temperatures. Peppers set the most flowers – thus the most fruit – between 65° and 80°F at night. Above about 86°F the blossoms drop off, costing you precious peppers. High winds, lack of pollinators and excessive nitrogen – such as with synthetic fertilizers – also cause blossom drop.
•Sustained daytime temperatures above 95°F causes the pollen to become sterile with lower harvests. Shading the peppers also reduces sunscald and the loss of immature pods from heat stress. Sunscald happens when leaves don't protect ripening peppers from the sun and they get a sunburned appearance.
•Pod drop happens when immature pepper pods drop off the plant, most often caused by high heat combined with water stress or excessive nitrogen fertilizer. Shade cloth reduces the heat, and a drip system on a timer moderates the moisture and avoids large swings that stress the plant, causing it to shed pepper pods. Consistent moisture is best for healthy growth – not just with peppers – and avoids the soil getting too dry between waterings.
•A good layer of straw mulch also maintains soil moisture levels between watering. We've found mulch reduces the amount of time our drip system is on, by cutting down the amount of water that is lost to evaporation.
•Peppers, along with most vegetables, like rich, well-balanced, and fertile soil to grow in. Too much of any one thing can be detrimental, and too much nitrogen leads to exuberant leaf and flower growth with little to no fruit set – most often seen in peppers and tomatoes. There aren't enough other nutrients to support the fruit growth from all of those flowers.
•Rotating beds where you grow peppers every year helps prevent many diseases and over-wintered bugs from attacking. Good soil fertility is the best prevention.
•Blossom end rot in peppers is much the same as in tomatoes, caused mainly by a lack of available calcium in the plant as it starts setting fruit – often large amounts of fruit at the same time. It can also be caused by large fluctuations in soil moisture, such as forgetting to water or a rain after it's gotten dry. The usual suspect – excess nitrogen – also plays a part here.
•Feeding the plants with a 20% solution of milk – 2 cups of milk in 8 cups of water – with a teaspoon of molasses gives the plants a boost in calcium and much-needed sugars for fruit production. Give each plant a cup of the solution once a week until the new fruit starts setting, then twice a month during heavy production.
Harvesting and Handling
•Almost all peppers go through several colors before ripening to maturity – both in color and flavor. The green stage is usually the least flavorful and sweet, but sometimes the spiciest and a bit bitter. As it ripens through yellow, orange and into red, the flavors become richer and deeper, with the sweetness developing and the heat mellowing. Try picking your peppers at all of the stages to see what you like best!
•A good rule of thumb for picking is if the pepper is easily removed from the stem, it's ready. If you have to pull or tug on the pod, it's still too early.
•This changes, of course, if you are harvesting continuously to increase the harvest – you'll be removing slightly young peppers. In this case, it's best to cut the peppers off the stem to avoid damaging the plant by pulling, as the stem will usually break before the stem does.
•Capsaicin – the "heat" in peppers – is located on the ribs and seeds. If you look closely, you'll see tiny yellow dots on the ribs – this is the pure form and is concentrated. If you prick one of these dots, you'll feel it's effects – sneezing, runny nose and itchy, watery eyes. Avoid touching it with bare skin to prevent spreading it to your face, eyes, etc.
•Some otherwise sweet peppers have a hot streak on the ribs and seeds, so now you know how to handle them.
•Some people are simply extremely sensitive, no matter how mild!
Myths
One of the biggest myths we've seen is the one that the different number of lobes on a bell pepper determines it's sex – such as "3 lobes means it's female and sweeter, 4 lobes is male and hotter"…
•First – peppers, like tomatoes, are "perfect" flowers, meaning they have both male and female organs in the same flower and can self-pollinate.
•Second off – and this is common sense – if this was true, you would need to buy "male" and "female" pepper seeds for reproduction, right? After all, if 3 lobes are "female" and 4 lobes are "male", it stands to reason they would produce the same sex seeds, thus the need for male and female seeds to be planted close to each other.
•So, where have you seen "male" or "female" pepper seeds for sale? Or maybe we should capture that market share?
Another myth is that all red peppers are hot, while green peppers are sweet.
•This most likely arises from people only seeing green bell peppers in the supermarket, and not realizing that they ripen into different shades of yellow, orange, or red and are still sweet.
•The fallacy is easily seen with both bell peppers and Jalapeños are both green on store shelves!

Lettuce info from Bountiful Gardens
1) Choose bolt-resistant varieties. To simplify that, we have a Summer Salad Collection and a Bolt-Resistant Mix
2)Put the seed in a dry, closed jar in the refrigerator for a few days. Most lettuce varieties do not like to sprout if the seeds have been at temperatures above 85 degrees. The refrigerator makes them think that they have been through the winter. They think it's spring when you take them out, and sprout readily.
3)Choose a spot with shade during the hottest time of day--11 AM to 4 or 5 PM. Other crops can make shade--a trellis of beans, for example. Or plant on the east side of your house. Or use Shade cloth. If you don't have a piece of ground that will work for you, use containers and keep them in a semi-shaded place. You can plant them in the garden later in the fall.
4)Plant in succession, a few every week or two rather than all at once.
5)Plant in the evening and water well.
