And The "Chilly Nilly" Prize Goes To.........

Hey Everyone,

And this year's "Chilly Nilly" prize goes to Ken of Bed 5 and Mark of Bed 45!

That's right you two!  Both of you tied for the coolest beds in the garden right now having a temperature of 65.3 degrees Fahrenheit.  It has been so nice to see the steady rise in temperatures this week and hopefully the few nights of approaching cold weather won't take us back too far from what we have gained. A special THANK YOU goes out to Reagan for helping me take all the temperatures Sunday evening. You were such a good helper!

Ken & Mark's Prize
Bu's Brew Bio-Dynamic
 Compost Tea Bags from Malibu Compost!

 and a link to information on the brew.
The week started off with a garden average of 64.7 degrees.  As of Sunday evening, we are currently right at 70 degrees for an overall garden average.  Temperatures run from our chilliest at 65.3, to our warmest at 77.4 degrees.  As always, I take temperatures late day between 5:00 and 6:30 p.m. to maximize any heat we may gain throughout the afternoon hours.  The temperatures of each bed are recorded with a digital meat thermometer, added together, divided by the total number of beds, giving us an overall average for the garden.  This gives us a pretty good idea of where our temperatures stand for planting purposes.

Here are the results for this week of recording:

Our chilliest section of the garden remains the area near the pecan tree and picnic table.  All beds in this section remain under 70 degrees with Ken being one of our "Chilly Nilly" prize winners at 65.3. This section actually has an advantage over others in the garden when growing cool weather vegetables in the spring as they can hold onto the chillier ground temperatures a bit longer.  This gives them the opportunity for a greater length of time harvesting before the heat takes over and causes the plants to end their life cycles. The overall average for this section as of Sunday is 69.0 degrees Fahrenheit.

The section of the garden that houses our special needs area is still the most consistent with their temperatures running from 67.1 to 74.2 degrees.  The average for this section is now at 70.2 as of Sunday evening.  When ground temperatures in this area climb, they tend to fluctuate less with the ups and downs that are common of early spring weather.  The largest advantage in this section is that both soil life and plant growth experience less stress due to fluctuating ground temperatures, which does go a long way in keeping plants healthy and productive once they get started.

The largest surprise was the warmest area of the garden at the last recording is now the second to the coldest when dividing the garden up into four sections.  It also houses one of our "Chilly Nilly" prize winners (Mark) at bed 45.  The temperatures in this uppermost right-hand section closest to the orchard have an overall average of 69.1 degrees.  The lowest is Mark at 65.3 and the warmest is 72.3 degrees.  In looking back at last year's recordings this scenario was the same as another bed in that section was also a "Chilly Nilly" prize winner.  It looks as if when looking towards the future at garden trends, this area has a distinct advantage for winning our "Nilly" prizes, grin!

Our last section on the right hand side of the gate closest to Dallas Hwy is still the warmest area overall. In fact, our "Garden Hotties" remain the warmest bed in the garden at 77.4 degrees.  The temperatures in this section range from a low of 67.2 to a high of 77.4 degrees.  The average for this section is 71.7 overall.  Many beds in this section have the advantage with the temperatures needed to support "tomato territory" and once the nights stabilize and the beds are prepped they will be off and running.

I am hopeful that this next little spell will be the last of the cold weather.  It is always a nice reminder though to respect those last frost dates for our area as planting too early can cause quite a bit of damage to our plants.  I will continue to keep us all posted!

A great big CONGRATULATIONS to Mark and Ken, you are sooooooo cool!  I'll drop the prizes by the shed my next trip over.

Happy Gardening,

Who's Our "Hottie"?

Hey Everyone,
And the "Garden Hottie" Prize goes to Susan & Steve Phillips of Bed 18!

Susan & Steve's "Garden Hottie" Prize!
Farmer D's Bio-Dynamic Blend Organic Compost
 providing a wealth of versatility in the garden!
Yes Susan & Steve, it's you!  You have the hottest bed in the garden right now!  Taking the garden temperatures this past week has been rather interesting.  While our desire is to see the ground temperatures consistently on the rise, we have experienced exactly the opposite.  Unfortunately, the few nights of extremely cold weather has taken our temperatures from the start of the week at 64.3 degrees Fahrenheit down to an average of 59.8 degrees as of Thursday.

I took all readings late day between 5:00 p.m. and 6:30 p.m. to maximize any heat we may have acquired throughout the afternoon hours.  I use a digital meat thermometer when taking temperatures as these do provide very accurate results.  The temperatures of each bed are taken, divided by the total number of beds, and the result is the garden average.  If you have two beds, I utilize the warmest or coldest one depending on which serves you the best for the purpose of contest prizes. 

As one may expect the chilliest section of the garden remains the area that receives the most shade near the pecan tree and picnic table.  This section had only one bed breaking the 60-degree mark.  That was John and Maxine's with a soil temperature of 61.8 degrees.  The overall average in this section is 58.1 degrees Fahrenheit.  

The most consistent section where the temperatures show the least fluctuation is the area of the garden that also includes special needs.  I believe that when we do obtain our heat, it is lost at a lower rate based on some insulation from the surrounding woods.  This scenario was also the same last year during the period at which temperatures were monitored on a regular basis.  The overall average for this section is 58.6 with those who cover on a regular basis having temps in the low 60's.

Now let's look at the garden's hottest areas!  The overall warmest section in the garden is the uppermost right hand side closest to the orchard.  The average for that area is 61.4 degrees with only a couple beds under the 60-degree mark.  This area continues to warm the fastest when looking at trends in the garden. However, this section also experiences the greatest fluctuations due to the openness of their bed locations.

The section that houses our "Garden Hottie" prize winners has both the warmest and coldest beds in the garden.  Steve and Susan's bed was 68.2 degrees Fahrenheit, which has to do with the fact that they remain diligent in their covering during periods of cold weather.  This allows them not only the ability to retain most of the gains in any ground temperatures they acquire but also the option to get an early start on warm season vegetables when the time arrives.  The coldest bed was number 22 belonging to Carol. Her temperature was 53.6 degrees.  It is always interesting to see how two beds right next to each other can have such a difference in micro-climates.  The temperature of Carol's bed is due to the mulch layer she has surrounding the garlic.  This will serve her very well during the bulbing stage, as if the soil temperatures get too high the garlic tends to shut down affecting its final size during the end game.  The overall average for this section is 60.9 degrees with only a couple beds under the 60-degree mark as well.

I am hopeful that the last of the really cold weather is behind us and we will start to see the warming trend that we look forward to with anticipation of great summer produce.  I will continue to keep us all posted! Congratulations Susan & Steve, you are the hottest!  

Happy Gardening,

Soil Temperatures for Peas!

Hey Everyone,

I have had some very good questions in relation to the best time to plant peas.  The key to growing a good set of peas in the spring is to get them up and out of the ground quickly to prevent the seeds from rotting in soils that are both cool and wet.  It is also imperative to get them in the ground early as once daytime temperatures reach into the 80's their production completely shuts down.

Peas take 4 - 5 weeks to germinate at soil temperatures of 40 degrees Fahrenheit, about 13 days at 50 degrees, and just 7 - 10 days when the soil warms to 60 degrees.   They will actually germinate with ground temperatures anywhere from 40 F to 85 F with their optimum falling around 75 F.  We are definitely in the ground temperature range to get them planted, STAT!

Sugar Sprint Snap Pea
For spring planting look for varieties that have a little heat tolerance built in.  Lincoln and Wando are two wonderful old time shelling varieties that do very well in the spring. Plants stand about 30" tall and they bear prolifically being able to take some of the early warm temperatures without shutting down their production.  However, these two varieties do require pro-active preventative maintenance for keeping powdery mildew at bay.  For those who like the snap peas, Sugar Sprint and Super Sugar Snap are wonderful varieties with incredible flavor that have excellent disease resistance to powdery mildew built right in.  My favorite snow pea is Oregon Sugar Pod II.  I cannot say enough good things about this snow pea variety.  The production is incredible as it produces two pods per each node on healthy disease free plants.  I have grown these for years with much success and they do extremely well in our community garden setting.

Green Meadows Healthy Garden Tip:

As with most vegetables avoid working with your pea plants when they are wet and try to keep foliage as dry as possible by watering at the base of the plant.  If picking peas in the morning, it is wise to make sure all dew is off the plant first.  These simple steps go a long way in preventing disease.  Decide if you will be pro-active or re-active with your pest protection and keep an eye out for aphids.  These are usually the first pests to arrive in the spring garden and pea plants provide good cover for them.  Compost teas, Actinovate, and AzaMax are wonderful organic approaches for promoting health, preventing disease, and keeping insects at bay.

As a special note - plants in the allium family such as onions, garlic, leeks, and shallots have a tendency to stunt the growth and production of pea plants.  For this reason, it is wise to plant them at the opposite end of the bed.

For those who would like additional information on planting and growing peas a link to Burpee is below for your convenience.  Its information is very straightforward and it contains the proper method for freezing any excess that some may find useful as well.  I have also placed a link to a very nice article on the differences in productivity between different varieties of snow peas.  This is excellent information for those who like getting the most bang for their buck out of their gardens.

Things Are Heating Up At Green Meadows!

Hey Everyone,

Well one week of nice weather and we probably all want to get out the bikinis and speedos.  It's not quite that warm yet, so keep those clothes on for a while longer.

As if I needed an excuse to run over to the garden, I thought it would be a nice time to take a temperature reading after the warm weather this week and the rain last night.  This would provide an accurate account of just where things stand.

Things are definitely heating up...............................

Soil Temperatures - Spring 2014 - Friday 2/21

All temperatures were taken between 4:15 and 4:30 p.m. on Friday afternoon. The sampling included 20 beds, five from each section.

Of the beds checked, our coolest was number 22 with a temperature of 54.3 degrees Fahrenheit.  As anticipated, this bed would be somewhat cooler in temperature compared to others in that section due to the nice mulch layer of pine bark nuggets.  The bed next-door (number 23) was a full 5 degrees warmer without any evidence of mulch on top of the soil. 

Our warmest bed is number 43 in the process of preparing to improve soil structure.  The temperature in this bed was 64.4 degrees Fahrenheit.  It is too early to tell if one area of the garden is warmer than another as at this point readings are well mixed in each section.  

After some basic math, the garden average at this time is 59.6 degrees Fahrenheit.  In looking at the extended 10-day forecast, they are predicting four nights below freezing with one in the teens next week.  This will take our ground temperatures back a bit.  It will be interesting to see if we are able to hold on to any of the rapid gain from this week. 

Happy Gardening,

Am I Ready For Spring Planting!

Hey Everyone,

All this wonderful weather is bringing us out to work on our beds and many are wondering when the right time to plant may be.  For the greatest success, it is important to look at several indicators other than just the weather or a date on the calendar before planting out.

Welcome to our garden Reagan!
Love your boots! 
While the sun is shining and the air temperatures have us chomping at the bit, the soil temperatures and workability are what is the most important.  Also, keep in mind how you will care for your seedlings and transplants once the cold weather returns.  Am I prepared for a frost and/or potentially a hard freeze?

Soil Temperatures - Spring 2014:

I took our initial baseline temperatures for spring planting last Sunday afternoon.  The soil temperatures in the garden are running between 39 - 48 degrees for all uncovered beds.  Those who have been diligent with their frost protection have temperatures currently in the mid 50's.  As one would expect the temperatures vary depending on how much sun and windbreak each bed receives.  We do have one exceptionally warm bed showing early signs of germination with a soil temperature of 58.9 degrees.  This bed will be the subject of another post.  Way to go Amy!

So what is the proper soil temperature for planting?  If you are direct sowing seed, each vegetable packet will list the optimum range for germination and the start of sustained growth. This is not the air temperature, but the temperature required of the ground.  You will also see a number for how many days it takes the seeds to germinate.  Take Redventure celery for example, the soil temperature needed to break dormancy of the seed is 55 -70 degrees Fahrenheit.  Germination will likely occur within 10 - 20 days.  This means if you plant the celery seed now, it will do nothing, wait until the soil temps rise to 55 degrees and it will probably take right around 20 days.  Let the soil warm a bit more and germination will occur more rapidly.  When the soil temperatures rise over 70 degrees, the higher end of the celery's spectrum, the rates for success at germinating the celery seed will then start to decline rapidly.  Also, keep in mind that many vegetables like celery will perform better as a transplant vs. direct sowing.

Mike, Sue, & Amy
Enjoying some time in the garden!
Most often, sowing seeds outside their normal temperature range leads to spotty germination, rotting, molding, and/or losing all viability within the ground.  If you are lucky enough for germination to occur, tremendous care will be needed to raise healthy plants as the environment is not yet conducive for sustaining the demand of their early growth.

What if I start with transplants?  If you start your garden with transplants that you have purchased or raised indoors, it is easy to follow the same guidelines.  If you utilize that same variety of celery as a transplant, it still requires the proper growing environment to do well.  This includes adequately warmed soil temperatures within the plants range to sustain that early growth.  There is nothing wrong with buying the plants now as you find them, however, it is beneficial to pot them up, prepare the garden bed with an environment conducive to your plant's needs, inoculate them to resist early pests and disease, and when soil temperatures are optimum, you are ready to go.

Green Meadows Healthy Garden Tip:

Planting in soils that have not properly warmed often sets the stage for the fungal attacks of many undesirable plant diseases.  It also weakens otherwise healthy transplants to the point they become vulnerable to assaults from a variety of pests.  This in turn fosters the use of additional pesticides and fungicides not only just for you but also for the community garden as a whole since disease and insects know no boundaries and will rapidly spread elsewhere.  Taking small steps to keep the garden healthy ensures we all get the most back from the time and effort we put in.

Definition of Soil Workability Explained:

Wonderful, workable soil with
a texture perfect for growing carrots!
So what does sow in early spring when the ground is workable really mean?  While we would like to think if the ground isn't frozen, it is workable.  Unfortunately, this isn't necessarily the case. Workable soil means the frost is completely worked out at all levels and no pockets remain.  The texture of the soil, although cool, is every bit as nice and easily amendable similar to what we would expect months from now.  Microbial life is coming out of hibernation and we see signs of its largest life form (the earthworm) being a little less sluggish.  The moisture content and soil temperatures are carefully balanced to prevent seeds from mold and rot and the environment is ready and conducive for young seedlings and transplants to thrive.  This is also a wonderful time to peek in on your pH and see if any attention is required.

It will be interesting to take another temperature reading this weekend to see how the warmer weather has affected things this week.  Over the next several weeks, we will be watching as things heat up for the planting season and once again be running our Chilly Nilly, Garden Hottie, and Average Joe/Jane contests for prizes.  I hope you will enjoy and follow along with us!

Happy Gardening,
