Shear madness

When I was a kid we had bushes in our yard. I guess that bushes were the landscape trend du jour, because it seems everybody had some form of them. We had Spirea bushes and a big Syringa bush that always seemed overgrown. The row of Spirea bushes provided us with a fun game of guessing which bush which kid was hiding behind. They were big and dense enough that you couldn’t tell who, if anyone was there. Yes, I know, simpler times, easily entertained, yada yada.

One thing about those bushes I didn’t like though was that a few times each summer they had to be trimmed. It was a hot, itchy task performed with a set of shears that looked like a giant scissors. I have to admit that while I didn’t like the job, I did like the way the bushes looked when the job was done. Big round green (or white when in bloom) balls that if done right would be perfectly symmetrical. For a week or so. Before they started growing shaggy again!

This week we are hedging our newer apple orchards. What is hedging? Well I’ve written before about the newer plantings being a solid narrow row of trees with no breaks. So hedging is how we can quickly trim the trees in summer to keep them from getting too bushy and shading the fruit. It shapes the row into a narrow canopy so that the sunlight can penetrate and color the fruit. The task is performed with a large sickle bar similar to the old hay mowers that we used to cut hay with. Mounted vertically on the front of a tractor, the blade shears the row as we slowly drive along. We can change the angle of the cut on the fly as needed. The result is a nice even “hedge” of apple trees with the fruit exposed to the sun. Here is a before and after shot.

Here is a video from the driver’s seat! Who knew that all that bush shearing would come back around to me later in life?

Grafting update

The grafts we did on the apple trees this spring are growing well. We’ve begun to trim back the original trees so that the grafted shoots get more nourishment and growth. Some current pictures here. Notice the grafted shoot coming out from the white taped area on the trunk! IMG_3839IMG_3843

Summer is a busy time filled with lots of varied tasks! Nobody ever says they are bored around here. If you do, we’ll put you to work!

Have a fruitful week!

Apples are measuring up!

So the bloom is finished, and the bees have moved on to their next jobs on other farms. The apples are growing larger every day. But if all the blossoms on an apple tree turn into apples, the tree would never be able to support them all! And the resulting crop would look like bushels and bushels of little red golf balls!

Some of the blossoms, however did not get pollinated. So those will not turn into apples. Some may have winter or spring cold weather damage and will not develop. And sometimes the tree, knowing how many apples it is carrying by sensing the volume of a hormone produced by each apple seed, will abort some of the apples in order to survive. (See my prior blog on Gibberellins). If left alone, apple trees will often have a big crop one year and a small or no crop the next. We growers realize that in order to have a decent crop year after year, we have to try to smooth out that cycle to have a moderate crop every year.

There is a short window of opportunity after bloom in which we can help the tree cast off some of it’s fruit if it is carrying too much. But at that point, we still don’t know just which fruits are going to continue and which will stop and fall off. That’s where apple measuring comes into play. For several years now, my daughters, Tressa and Taylor, have taken on the task of measuring fruitlets every three days over this period. First they mark 75 fruits on each of 5 trees in each orchard that we are tracking.

Blue ribbons mark each cluster of apples.

Each cluster is numbered, and each apple as well

Then they measure each fruit with a digital calipers and record the data.

IMG_4331

It is a time consuming task, repeated every 3 days in each variety that we want data on.

The data is entered into an Excel spreadsheet program. After 3 or 4 sets of data have been entered, we can crunch the numbers and the program will tell us which fruits are growing and which are slowing down and are going to eventually stop. This is a huge help to us in determining the eventual size of the coming crop, and with this information we can decide whether to leave the tree alone or to “help” it to cast off some of it’s fruit. We can do that by applying some products that stress the tree slightly so that it will decide it can’t carry quite so much. The tree will then kick some more fruit off and help regulate the crop.

The process isn’t as easy as it sounds. There are many other factors involved; tree health, weather, and previous year’s crop all play a role in the big picture of crop size and the response that we may get when we try to”help” the trees. But the many hours of work and thousands of measurements that these girls take are an invaluable resource for us, making a difficult decision making process more precise. Hats off to them!!

Just another example of how technology and hard work are changing farming for the better!

What’s Growing On?

Well our growing season has finally caught up. Back in the middle of April, we were running in between 3 and 4 weeks behind normal in accumulated temperature degree days. Since then we have slowly been gaining and our trees have been catching up in development due to some warmer than normal weeks. And by this weekend, we will have recovered all the way back to where we should be on average. This means the tree growth stages are now right where they usually are this time of year. Funny how all our fretting about early springs or late springs really doesn’t change anything. On the 1st of February we were 19 days ahead of normal. Then came the cold March and April that swung us the other way. And here we are now, right on time.

So what does right on time look like? Here are some photos of each kind of fruit, taken today.

Grafting update

Two weeks ago I wrote about grafting apple trees to change them from one variety to another. Since that was done, the little apple wood buds have woken up and are beginning to grow. That means the grafting process was successful! We don’t expect that every single one will succeed, but it’s good to see progress! Once these little shoots grow to 6 inches or so, we will remove about a third of the original tree so more of it’s resources can go to the new “adopted” branch. If this first season is successful, next spring we will remove all the rest of the original tree and the grafted shoot will become the new tree.

The new shoot is starting!

It is always amazing to me to see how things grow. God makes trees to grow and produce fruit, and season after season, barring frost or other natural disasters, they will expend all their energy doing so. It’s what they were created to do. We should all take a lesson from them.

Have a fruitful week!

Grafting

So a while back in my blog I mentioned that we would be doing some grafting, changing some apple trees from one variety to another. We did this task on this past Tuesday. In this blog, I’ll show you how this type of grafting works!

The process actually began back in February when we collected dormant shoots from our then-sleeping trees. This wood must be kept dormant, so we store it in refrigeration until it’s time to graft.  The shoots are then trimmed into little sticks, called “scions”, about 3-4 inches long with two buds on each stick.

IMG_4552
Trimming the “scions”

The scions are then trimmed on one end to expose the different layers of the wood from the outer bark down to the inner wood. They are kind of paired down on two sides to form a wedge.

IMG_4576      IMG_4579

Then a cut is made into the trunk of the host tree with a sharp grafting knife. These knives are extremely sharp and sturdy.  The cut that is made is very precise and designed to accept the scion stick with it’s trimmed end. The scion is inserted into the cut, lined up so that the bark tissues are together, and pressed tight.

The grafted area is then wrapped tight with tape or elastic plastic to keep the tissues secure and in place. Then the area is painted with a wax based product that seals the cuts up . This will keep disease and insects out while keeping the tree tissue clean and the moisture in.

IMG_4553  IMG_4557

During this work the scions and the trunk cuts cannot be allowed to dry out at all, so time is of the essence. The professionals that did this work for us can perform the whole process in a matter of seconds! Each person on the crew has a specific job to do, and it is replicated thousands of times in a day. At our farm on Tuesday, they grafted 1,250 trees in just a few hours! Then on to the next farm.

Here I’ve linked a short video of Robbi VanTimmeren, who leads this dedicated grafting crew, performing a graft on one of our trees. Even though she slowed it down some for us, it goes quickly so you may have to watch it more than once! Notice that every action is performed with exacting precision. She makes a difficult task look much easier than it really is.

In the weeks ahead I’ll keep you posted on the progress these trees are making. The goal is that hopefully that little scion that we put in place this week will eventually take over and become the new tree, changing these trees from Red Delicious over to Honeycrisp! In the meantime…

Have a fruitful week!

Finally…!

Sunday was a beautiful day. Warm and sunny and just right for taking a walk. In church that morning we sang the song “This is my Father’s World.” It fit the day perfectly. Hard to imagine us singing that a week earlier when everything was canceled due to a snow storm! It just wouldn’t have felt right.

So only a week ago we were walking around in fresh snow. Now the snow is gone, and the fruit buds are beginning to pop! We are seeing the first green leaves just poking out of the apple buds just in the last couple of days. Each of these tiny buds holds the flowers that could develop into 5 apples. And with the warmer weather, I guess they decided it’s time to emerge. It is amazing how those little buds can sit there wrapped up tight all winter, and then with a few warm days flip the switch and poke their little leaves out into the sun. How do they know?

IMG_4521

We are about two weeks behind average  right now, but we will begin to catch up quickly with the warm temperatures forecast for next week. Just in the last week we have gone from 20 days behind to 14 days behind normal!  We are busy pruning cherries and peaches now. Most years we wait to prune them until they begin to grow in the spring. Since they are more tender and sensitive to cold winter temperatures, we want to see which branches and buds are growing and which are not. It is easier to see and remove branches with winter damage that way. We will soon be planting trees as well when the soil is dry enough. When the weather warms up, it seems our “to do” list grows quickly too!

But even though we are really busy, all this week that song has been running through my head. So I’ll put a couple of verses here, and just maybe you will see what I have been seeing all week. In spite of all the work on the farm, Spring is amazing!

This is my Father’s world
And to my listening ears
All nature sings, and round me rings
The music of the spheres
This is my Father’s world
I rest me in the thought
Of rocks and trees, of skies and seas
His hand the wonders wrought
This is my Father’s world
The birds their carols raise
The morning light, the lily white
Declare their maker’s praise
This is my Father’s world
He shines in all that’s fair
In the rustling grass, I hear Him pass
He speaks to me everywhere
Have a fruitful week!

Planning to plan…

Well I guess we don’t have to worry about spring coming early this year! We may have to worry about it coming at all?! I was at a grower meeting this morning where we talked about the weather. Farmers do that. It was pointed out that as of February 1 our temperature accumulations were about 19 days ahead of normal. And now, six weeks later temps are running 19 days behind normal. That’s a 38 day swing! How do we make plans when things can change so drastically? Answer? Relax and roll with it. We can’t change the weather, no matter how much we worry about it!

bloom-blooming-blossom-908308

Sometimes no matter how much we plan, things don’t turn out the way we think they are going to. Travis and I spent much of the last 2 days preparing 1,200+ young trees for grafting in a few weeks. These trees were planted in 2015, and have not grown as well as we expected. They had a hot ride from the nursery on the west coast back when we received them, and much of the wood had heat stress damage. We planted them, knowing that they might not perform as well as we hoped(planned?) The other factor that played into our decision to change the trees, was that the variety that we had selected when we ordered the trees back in 2012 is now falling out of favor with consumers. So what to do? We have decided to change the trees over to Honeycrisp apples by grafting a Honeycrisp bud onto the existing tree, and starting over. Since the trees are already in place and have a decent root system, we hope to convert this part of the orchard over to a more popular variety and give these trees an new lease on life!

IMG_4469
We have removed the branches from one side of each tree to make room for a new bud to be added! That way it won’t have competition.

Grafting is a delicate art. It is the process of taking part of one plant and marrying it to another similar plant in order that it can continue it’s life there. In a few weeks we will be joined by an experienced crew of tree grafters to accomplish the first steps of this task. The complete transformation will take a few years, but we think our plan will be worth all the work and the wait. I’ll be sure to show you more of the process when we begin, and keep you updated from time to time on the progress of this project.

Here is another plan-buster. In this same orchard are rows of Gala apples. And every so often we find a tree that is definitely not a Gala. It’s like that old “One of these things is not like the others” song from “Sesame Street”. You can see it in the picture below. So we will be grafting these trees over to be Galas like the rest.

IMG_4467

Cutting back a “Who knows what?” tree

So while our best laid plans don’t always turn out the way we think, we will adjust and keep working toward our goals. Who knows what will change in the meantime? But it will all work out. At least that’s my plan! 🙂

Have a fruitful week!

Brushing up on Spring!

Spring has Sprung!! Or at least the calendar says so. The weather has moderated some, although it is still freezing at night, and we still have remnants of snow laying around. Apparently winter isn’t giving up easily this year. Maybe it doesn’t like being told to go home!

Most of our apple and pear trimming is finished. With just a few rows of Fuji and Spy still to go, and some young Pink Lady apple trees that are still hanging on to last year’s leaves.

IMG_4412
Time to prune them, leaves or not!

I guess they aren’t ready to call it spring yet either. We are spending much of this week removing the trimmings from our winter pruning out of the orchards. This dry weather stretch has been helpful, because we can get around the orchards without tearing up the sod with our tractors. Some years that is not the case.

So what do we do with all that brush? Well the younger trees have small prunings that we chop into smithereens and leave right in the orchard. That’s good for putting the nutrients back into the ground. Our chopper has limitations though, so bigger limbs must be removed from the orchard and piled up to be burned.

IMG_4418

That’ll be some big hot dog roast! Whichever way we dispose of the brush, it has to be raked or swept into the center of the rows. And that requires a body and a rake. As kids growing up in the apple business we all knew what Spring Break meant. It meant raking brush. No, not on a beach somewhere in Florida or Mexico. Right here. On the farm. And whether Spring Break was early or late, it always seemed to coincide with…you guessed it…raking brush. Some years were cold and wet. Others were warm-ish and almost pleasant. But the job remained the same. It was always better if we could get some cousins or neighbor kids to help. The monumental task seemed to go faster that way. By the end of the week we were almost looking forward to going back to school!

IMG_3486
This row is raked!

With the brush cleaned up, I like the way the orchard looks in the spring. All the trees standing at attention, poised to begin the growing season.

IMG_4409

A fresh start. A new year. And while we don’t know yet what the season will bring, we are promised that spring will come, growth will begin, and the roller coaster ride to harvest will never be boring or predictable. Unlike raking brush….

Have a fruitful week!
