Favorite Cherry Tomatoes

assorted cherry tomatoesPicking the “best” cherry tomato is an impossible task, but we can make some recommendations based on plant size, fruit color, and flavor. The first consideration is size of the plant—how much space do you have available for each tomato plant? An indeterminate variety can become an enormous, sprawling vine of 6’ or more. A determinate Tumbling Tom or semi-determinate Lizzano can spill gracefully from a hanging basket or off the side of a raised bed. If you need a very compact plant, try a red or yellow Sweet ‘N’ Neat, which will stay under 16” high. They do best when they can trail a bit, though. They are so short that the fruit can hit the ground in a traditional planting.

Fruit color is a fun factor for many tomato lovers. Combining yellow tomatoes with purple basil is a colorful twist on traditional Caprese salad. Cherry tomatoes come in red, orange, yellow, purple, brown, and black. Fruit can be anywhere from traditional grape shapes to 1” orbs or pears. Not –red varieties include Sunsugar, SunGold, Yellow Pear, Black Cherry, Brown Cherry, Indigo Rose, and Sweet N Neat Yellow.sungold tomato

Cherry tomato flavor is generally quite sweet in comparison to other types of tomatoes, which makes them great for snacking and popular with kids. If you are overwhelmed by your cherry tomatoes (which can happen in August) consider a tomato exchange with an equally overloaded friend or neighbor. You may not have fewer tomatoes at the end, but you’re likely to have a mix of varieties and flavors.

Hybrids, Heirlooms, and GMO

Selecting varieties of vegetables can seem daunting when all you want is a slicing tomato and there are nine slicer options on the shelf. How to choose? Why should you pick one variety over another, and what’s the difference between hybrids and heirlooms, anyway?Tomato

Hybrids: Plants are a cross between varieties as a result of pollination & selective breeding. Each parent plant brings different characteristics to the table (just like people!) and the resulting plants have a combination of desirable traits. Generally, hybrid plants have increased disease resistance, increased yield over other varieties, and their fruit ripens more quickly than heirloom fruits. They may also be bred for unique colors, shapes, or sizes. Keeping in mind that it took two different plants (with specific traits) to create the hybrid, it makes sense that seed saved from these plants will not produce the same “children”– just as a child is not a clone of either parent. Humans have been hybridizing plants for nearly as long as we have been planting them and it is a very natural way to produce plants that match our current needs.heirlooms

Heirlooms or Heritage: Plants meet specific criteria to qualify:
1) Variety has been in production for over 50 years or was grown prior to 1940
2) Plant can be open-pollinated to create viable seed (many hybrids produce sterile seed, since the resulting seed creates undesirable traits)
3) Seeds produced will create a plant that is similar to the parent plant
Heirlooms are maintained for many reasons, and the foremost of these is flavor. Fruits often have a shorter “shelf life”, generally take longer to ripen, and the plants have less disease resistance than hybrids (which have been bred to combat these challenges). But, oh! The sweetness and flavors are amazing, and it is well worth including them in your garden. It is also nice to know that you are experiencing flavors and colors that your ancestors would recognize.corn

Genetically Modified Organisms, or GMO: Plants (as well as animals & bacteria) have had genes added or subtracted to their DNA by means of genetic engineering. This is done to increase yield, pest/disease resistance, herbicide resistance, or to create otherwise desirable traits. It is extremely rare for the home gardener to encounter GMO plants or seeds. The breeding is expensive, and consequently most of the research is centered on commercial cash crops such as corn, canola, soy, or cottonseed. Studies have shown both positive and negative impacts of this engineering and public opinion remains mixed.  GMO crops are grown as large scale, commercial farming crops.  It is extremely unlikely for the home gardener,  or even your local garden center, to have the option to purchase a GMO plant or seed, a concerned gardener can opt to purchase only seed that specifies that it is non-GMO.

Back to the original question— why should you choose one type over another? Most of us here at Echter’s grow a mix of heirloom and hybrid varieties. Those growing in containers will probably select hybrids, as there are varieties that have been bred to stay petite and won’t take over a patio. Gardeners with a lot of space and the willingness to wait until late summer for fruit will likely choose heirlooms. Mountain gardeners need plants can handle a chill and fruit quickly. Most of us fall somewhere in between and want some early hybrid fruits and a smaller, later crop of heirlooms. Mixing and matching your varieties will give you a steady stream of fruit throughout the summer and encourage you to try something new each year.

Seven Easy Gardening Activities for Kids

We all know that kids and dirt go together like peas and carrots, which makes gardening an easy activity to encourage. It can be an amazing journey of discovery to realize that sun and water will create sunflowers and watermelons, and there are a lot of wonderful activities to investigate year-round. Young children can help with seeding and planting, and older children can take it a step further by learning how plants grow and trying experiments in the garden. After all, much of gardening is experimentation, and that’s what makes it fun!

seeds-1217133_1920
1) Try starting some seeds indoors! Choose larger seeds like beans, peas, or marigolds that are easy to handle and count. Even if these aren’t plants that make it into the garden, it’s fun to count the number of days until they come up and watch them grow. Older children can measure how tall they grow in a week, or how long it takes for each set of leaves to form and expand.

2) Direct seeding of easy annuals—we’ve all encountered plants that seem to grow of their own accord every year. Cheery pink or white cosmos are quick to start, as are marigolds, sunflowers, and pumpkins. Zinnias come in a riot of colors. Bachelor buttons and nasturtiums can be tucked in to fill out bare spots.

3) A plot of one’s own—foster a sense of responsibility by creating a small plot for each child. A 3’ stretch along the fence can be a trial garden for different kinds of flowers or vegetables, and can be decorated with painted rocks or other handmade garden-themed crafts. Let each child choose their plants or seeds for a garden that is their own creation. Take picbean-tipitures of the progress and help behind the scenes as needed.

4) Living playhouse—it’s easy to grow a sheltered play space with either giant sunflowers or pole beans. Simply plant seeds in a circle big enough for two (or more!) people and be sure to leave a section that will eventually be a door. Once the plants are up, add tall stakes and tie them together at the top to form a cone shape. The seedlings will grow through the summer and create a shady nook by summer’s end.

5) Plant a fairy, gnome, dinosaur or toy garden! Miniature gardens are all the rage right now and they can easily be planted in the ground or in a container (to bring in for the winter months). Select small groundcover annuals and perennials for outdoor gardens. Wee houseplants in 2” pots are perfect for indoor landscapes. Miniature gardens can also be planted in a terrarium or former fish tank. The possibilities are endless! If toys end up in the garden, be sure that they are plastic, wood, or resin to stand up to the weather.

6) Create a habitatforbutterflies by choosing flowers and plants that either have a lot of nectar or tasty leaves. Butterfly larvae feed on specific plants (such as milkweed for monarchs) and adult butterflies feed on flower nectar. Try tracking the different types of butterflies you see in your yard.

7) Make a garden collage (or several over the season) to document what was spotted in the yard. Collect leaves, press flowers, and draw pictures to tell the story of this year’s garden. Older children can keep a garden journal and little ones can be prompted to chime in with an adult scribe.

Blossom End Rot Isn’t the End

Most gardeners have heard of blossom end rot, or experienced it firsthand. The telltale sign is a big brow/black soft spot developing on the bottom of tomatoes, peppers and eggplant. It can also be seen on other vegetables, although it tends to offend us most when it happens to our tomatoes. After all, we’ve spent a lot of time growing and anticipating those luscious, juicy fruits. The disappointment to our taste buds is nearly inconsolable. Fear not, there is no need to throw in the trowel. A little bit of TLC can prevent it from affecting later fruits.

So, what is it? Blossom end rot is technically the result of calcium deficiency. Now, I know you probably think I’m off my rocker. After all, our soils have plenty of calcium. But there are a number of factors that can inhibit the plant’s ability to translocate the calcium. In other words, it’s not really the lack of calcium, but that the plant is unable to make use of it.

The most common causes for blossom end rot is entirely related to environmental and cultural conditions. When there is excessive moisture, as in our recent rains, followed with an increase in temperatures and a quick dry out, it’s the perfect storm, so to speak. Voila! Soft, water soaked brown patches appear on the bottom of the fruits.

Ferti-lome Yield Booster
Ferti-lome Yield Booster

Ferti-lome Yield Booster is a handy spray that staves off damage to future fruit set. While those that already show the damage cannot be saved, Yield Booster can protect those fruits yet to come. So there’s no need to worry. We just have to exercise a little more patience. It’s easy to use. A word of caution…spray in the cool of the evening or in the very cool morning hours, allowing enough time for the spray to dry before the sun hits it. Plants sprayed in the heat of the day, in the peak of the sunshine, often suffer foliar damage. This is true, whether you are applying foliar fertilizers or other chemical treatments. Be sure to amend the soil further this fall and next spring before planting to improve drainage, as well. Soil that compacts easily tends to hold excessive moisture levels longer than the plant can endure.
Rest assured, there’s no need to give up on your dreams of delicious, tasty tomatoes!

When Can I Plant?

Here comes the sun!  With it and the warm day temperatures of spring comes one of the most frequent questions we hear.  “Can I plant this now?”  The answer depends on the plant and particularly, on the nighttime temperatures.  Our early spring days are often beautiful and daytime temperatures may reach well into the 70’s.  It’s the night temperatures that really tell us when it’s safe to plant.  Our last frost date is generally considered to occur around May 20th.  While some years the date arrives earlier, there are occasional years when it occurs as late as June 1.  We’re eager gardeners and antsy to get plants in the ground, but if we aren’t mindful of the night temperatures, we can do more harm than good.

Before I get carried away talking about plants, I should mention the value of hardening off your plants before you plant.   What is hardening off?   It’s a process that acclimates plants prior to transplanting in order to reduce the risk of transplant shock.  The process takes a few days, but it’s worth the investment of time, particularly in early spring or late summer heat.  Day one, place the plants in a shaded area outside and move them indoors or into a garage that night.  Day two, place the plants in partial sun for the day and move into the garage or indoors at night.  Day three, place the plant in a sunny spot for the day and move to a protected outdoor location, like against the house or under a porch, for the night.  Day four, move into the sun for the day and leave them in the exposed location for the night.   Day five, plant.  In late summer, when the temperatures are well over 80°F, I often use the same process, but shortened to 3 days.  This helps prevent sun and wind burn to the young plants.  Hardening off plants increases successful transplanting.

Now back to what we can plant and when we can plant it.

Hands down, the most common plants asked about are tomatoes and peppers.  Tomatoes and peppers, two of the longest season garden vegetables, prefer night temperatures to be above 50°F for about a week before they are planted.  The ground needs to be consistently warm for them to do well.   If we plant too early, and the night temperatures are still cold, plants set less fruit and are often more susceptible to problems like blossom end rot later in the season.

There are helpful tools like Season Starters that can be used to warm the ground earlier than traditional planting would allow.

 

They should be set up for 7-10 days to warm the soil, before they are planted with your seedlings.  Once planted, the plant protectors act as insulators against cold temperatures, much like a mini greenhouse.  Generally, Season Starters can give you a jump start by several weeks.  Set them up about April 15 and you can plant inside them a week later.

These dates are approximate for the Denver area. Safe dates vary from year to year, suburb to suburb, and even from one location in the garden to another. Covering plants on unusually cold nights will help protect them. On extremely cold nights it may be necessary to dig plants up and bring them inside.

Seed Starting Basics

Have you ever gone to the grocery store and said, “Oh my! Four dollars for 4 sprigs of basil!” Well, there is an easy way to get what you want and help you save a bit of cash, as well. Not only will starting your vegetables, herbs, and flowers from seed help the pocket book, it is a wonderful thing for the whole family to watch a plant grow from a tiny seed, and there is nothing more rewarding than harvesting a crop that you grew.OLYMPUS DIGITAL CAMERA

The first thing to do is determine where you plan to plant your garden outdoors. Most vegetables require full-day sun to mature properly. There are only a few that will grow in partial sun, mostly leafy greens. Knowing your available light will determine what you can successfully grow.

Read the seed packet. There should be a description of plant characteristics, giving you an idea of what to expect. Look for information about the preferred season to grow, seed sowing depth, days to germination, and days from transplant until harvest. There should also be information about preferred light and whether or not the seed will do best if started indoors or directly sown into the outdoor garden bed. Often there is information about the disease resistance of the variety, too. In the case of tomatoes, there should be a notation of the plant being determinate (bush variety) or indeterminate (vining varieties). Some seed companies provide additional information inside the packet. If you prefer to use organic seed, look for the USDA organic symbol on the front of the packet. You won’t find GMO seeds at Echter’s. In fact, GMO is primarily used on commercial farms and is rarely seen in the garden center or home garden.

Why is the information on the packet important? All of that information allows you to select the right varieties to grow in your climate and those that suit both your needs and your taste buds.

Is the plant warm season or cool season? This will help you decide when to plant said crop for instance things like spinach, kale, chard, Brussels sprouts, are all cool season crops — meaning you can start those 4-6 weeks before the average last frost. Whereas things like peppers, tomatoes, zucchini, need to be started after the last frost. I know it can be confusing, but on most seed packets you will have that information of cool season or warm season right on the front.

What is days to emerge? This is how many days it will take that seed to, as we say, crack or germinate. It is when you will see the first sign of life the first little showing of green.

How many days until harvest? This means how many days it will take from the time you plant in the ground or container, until you will be able to harvest said crop, or see blooms on flowers.

Should I start my seeds indoors our outside? Most seed packets will recommend whether to start inside or outside. For instance it is a good idea to start your tomatoes and peppers inside since Colorado has such a short growing season. Whereas things like corn, leafy salad greens and root crops like carrots prefer to be directly sown into the ground.

Now that you can identify what and when to plant there is no stopping you! You will have a few other needs to get started. You’ll need seed trays and seed starting mix or Jiffy pots. It’s also helpful to have some plant labels so you can note the date the seed was sown and the variety.

A heat mat is helpful, particularly if your home temperature is on the cools side. It will heat the soil evenly, providing optimal conditions for seed germination. Humidity domes can help keep the necessary moisture around the seed to aid in germination. If the light on your windowsill is inadequate, try adding indoor grow lights. Most are energy efficient and you’ll use them for years to come.

If you are starting indoors it will be important to have additional pots on hand, usually 3”-4” diameter. Once seedlings have established, they will need to be potted up (transplanted into larger pots) until it is time to transplant outside.

It’s a good idea to keep the empty seed packets for a couple of reasons. The first is that it can be a few months before your plants reach maturity. In that time, it’s easy to forget details that may be handy to know as harvest time approaches. The second is that you may find out you love that variety and having the seed packet will help you remember what to buy the following season.

It is important to remember that gardening involves some trial and error, and there is no fool proof method. Mother Nature has her own ideas sometimes. It never hurts to try new things. If you are successful you will not only reap the benefits of tasty veggies, aromatic herbs, and beautiful flowers, but the confidence that, yes, you can grow something from a seed!

Late Season Vegetable Gardening

????????????

Late summer is a great time to plant fresh crops of lettuce, spinach, broccoli, and cauliflower. Starting them from seed in late July and early August allows us to grow them into the fall. Cole crop vegetables thrive as the temperatures begin to cool in September and October, taking frost in stride. Most short season root crops will do the same. It’s a good idea to keep a frost blanket handy, though. Frost blankets will prevent your late season crops from suffering damage in the event of an early hard freeze.

What can you grow? There’s quite a list, but one of the important things to consider is the number of days the crop needs to reach maturity. This is usually on the front of the seed packet. Stick to plants that need less than 75 days to mature for late crops. How do you know when to start fall crops? Count back the number of days the crop needs to mature, from the average first frost date. In Denver, that date is October 11. So if your lettuce takes 60 days to mature, count back from October 11th and seed them on August 12th. If you don’t have a calendar handy, this website is easy way to calculate dates; http://www.convertunits.com/dates.

Here are some favorite fall crops to try:

Beets, Bok Choy, Broccoli , Cabbage, Carrots, Cauliflower, Collards, Endive,  Kale, Mustard Greens, Peas, Radish, Spinach,  and Turnips

Choose varieties that are less susceptible to powdery mildew for fall gardens.   Cool nights and moisture condensation on the foliage is all the spores need to wreak havoc on your vegetables.

Planting crops a week apart, successively, will extend harvest well into the fall.  Enjoy!
