Thinking on Trees

The few days of beautiful February weather got me kicked off to a good start on my yard work, which means I haven't had as much time to sit around the house and blog.

Yesterday I got the pleasure of raking the yard and laying down bark mulch, as it turns out 4 cubic feet of bark doesn't come anywhere near what I will actually need to finish the yard around our patio.  I was surprised at just how little it did cover, today I will go back to the store and get another 6 bags (since that's likely all my car can carry at once) and see how much farther it gets me.

In the meantime I am on a mission to discover what would be the best plant to put in the front of my house, where it is bare and gets no shade at all in the summer from about 2 pm to sunset.  If I can come up with something attractive with flowers or fruits that will shade the house it could make a big difference in our cooling bill during the summer heat, and provide food or bouquets or at the least a nice centerpiece to the house.  I have considered a lilac, but am thinking that it may be too slim to make much difference in shade.  I've also considered trellising grapes, wisteria, or clematis, but again I am not sure they would get large enough to provide much shade.  An evergreen could make a statement, and won't make a big mess like deciduous or fruit trees, but it also won't make a floral show in spring or fruits later in the year.  The other option that came to mind was a cherry tree, or other fruit tree that wouldn't require cross-pollination.  I'd have flowers, fruits, a mess to clean up, and a shade tree large and branching enough to make a difference.
This time of year the house is shaded, but by summer there will be nothing to keep it cool.

The annuals are not nearly so difficult to decide on since they change each year, but a tree is a big deal.  It will be there for years, and probably won't produce much for several years after planting, I need to be absolutely certain before selecting a tree to put into the yard.

When you are considering a semi-permanent to permanent change to your landscape here are some things to keep in mind:

-How big will it get?
-How much maintenance will it require?
-Will it drop fruits or leaves that need cleanup each year and do you want to take on the extra work?
-Will the planting location make a difference in other things? Will it shade the house, or garden?  Could the roots grow too large and damage sidewalks, driveways, or water pipes?
-What are you trying to gain from the planting? Shade, flowers, food, etc.
-If it is a fruit tree, will you need more than one for pollination?
-Will you move before you can reap the benefits of the plant? If you expect to move in 3-5 years it doesn't make much sense to plant a tree that won't offer much shade for 10 years.
-If you select for appearance, be sure to take the time to find out if your tree or shrub is native, and if it has many known pests or diseases.  If you select something for its health to begin with, you will have fewer worries later on.

The Arbor Day Foundation can be a great resource for learning about trees, and even offers 10 free trees selected for your area as a membership incentive (they also offer member discounts for the purchase of trees). This can be a great way to get some trees started in a larger landscape, or you can ask friends or neighbors if they'd be interested in sharing your 10 trees.  The small donation/membership cost is worth it if you are planning to add trees to your yard, but aren't necessarily seeking specific types.  When I joined a few years ago it was primarily just to make a donation to what I felt was a worthy group, I ended up sending my free trees to my nephew who has several acres and raises fowl as well as a garden, he made good use of the trees which I didn't really have the space for at the time.

I am definitely leaning toward a cherry tree, however there is some debate over what type; my daughter likes sweet cherries, while I prefer to preserve pie cherries. There are combination trees available, but I have never seen one that did as well as separate sweet and sour trees.  Next stop, check with the local nursery on good selections for our area, and do a little research on planting a new fruit tree.

Battle Blackberry

As I went out this morning to take my own advice and get an early start on spring cleanup in the yard, I tidied up the front and side yards, then closed my eyes and held my breath before glimpsing into the dark, creepy back yard.  Normally when I refer to my back yard I mean the side yard with the garden and patio.  Primarily because I like to pretend that the muddy, weedy space at the actual rear of my home does not exist.Which is part of the reason it is in its current state.  Full of old playground equipment from the previous tenants, random junk that broke and couldn't be fit in the trash can, some sort of annual weed that has set up a colony and breeding program, and huge masses of blackberries.  Well, they aren't THAT huge actually, it's only a 24x12 foot yard.  When we first moved in this yard was in decent, if not particularly hospitable condition.  The swing set worked and the trampoline was fun, but they took up a lot of space and the yard was surrounded on two sides with sheds, one side with a fence, and the other side with the house.  It got light for a few hours in the morning and became a murky cave after that point.  Two years ago the neighbors behind us removed a large birch tree that was dying; the birch had shaded the back yard so I was happy to have it gone.  As it turned out though, the birch had also shaded and restrained a small patch of blackberry canes underneath it too.  Once the tree was removed the blackberries had a heyday, growing up over the fence and landing in my back yard where they immediately sprouted suckers and new roots. 

Since I don't spend much time back there other than to toss scraps in the compost pile, I didn't really notice this until it was too late.  By then I had a 24x12 blackberry patch filling every space in and around the playground, crawling behind both sheds, and working it's way up over the bean trellis into my garden area. 

I have cut them back a few times to prevent them eating my house, but always during the growing season when they will quickly just sprout two more heads for every one that is cut, like a hydra.  Today I was ahead of them, and it made me think that as a garden blogger it was imperative that I share my intimate knowledge of blackberries with readers.  Now that my shed has been unburdened of blackberry canes I am free to take a break to write.

Blackberries are cane plants, they grow from seed, or rhizomes, or underground runners, or above ground runners; pretty much they can grow from anything.  They are thorny, pernicious weeds in most areas.  Mind you, when I am talking about blackberry as a weed I am referring to Himalayan blackberry, there are many other varieties of blackberry that are far less invasive and make delicious jams and pies too. 

The only way to beat blackberries is to kill, kill, kill year after year.  For large patches it's sometimes easiest to clear a small area each year and work it down until there is nothing left.  If you can borrow, or already own a goat, they are the blackberry's natural nemesis and will eat each and every cane until nothing is left if given the opportunity.  I think the very best way to handle blackberry destruction is to borrow a goat each spring to destroy new shoots until the shoots finally give up and stay dead.  My dad's neighbors put their goats out near a huge patch of blackberries on their property and a few months later were rewarded with a mobile home!  The house had been buried in blackberry canes for so long no one even knew it was there until the goats ate their way around it.

Not everyone has the goat option though, if you don't you'd better don your hat, leather gloves, sturdy pants, boots, and long sleeved shirt.  This is part of the reason to cut them back early in the year, it's still cool enough to keep yourself completely covered.  Cut down canes with a machete, or loppers, or pruning shears.  Most lawn weed whackers will just bend thicker canes and not actually cut them.  Cut down to the ground!  Rake up all the debris from your murderous rampage, then throw it out with the trash or in a yard debris bin.  Do not compost blackberries: they may grow back in your compost, seeds may sprout in the compost or garden beds where it is used, and dropped thorns might still be there when you add the compost to your garden. Ouch!

Once the canes are cut to the ground and the cuttings have been disposed of you should dig up as many root balls as you can.  They can grow back from even the smallest root, but if you can remove some of the largest ones you will have a head start, by leaving only small roots which are not well-stocked with food. This is another reason to kill blackberries early in the year, the ground is still soft and moist which makes root removal much easier.  If you keep all new shoots cut to the ground as soon as they pop up these smaller roots will eventually die, since they have no leaves from which to absorb sunlight, larger roots have much more stored nutrition and will live longer.  At this point you simply have to maintain the status quo, despite the blackberry's attempts to regrow.  Cut new shoots during the spring and summer season, in the fall lay down a VERY heavy mulch layer, next spring you can mow or weed whack new shoots if they are small enough.  Continue this way until you finally stop seeing any growth, but pay attention, check back every few weeks to ensure they really aren't coming back.  I also don't recommend doing any permanent landscaping in the area until you are certain there will be no regrowth, it's awfully hard to pull blackberries out of retaining walls and garden borders.  This may take a few years but eventually you can win the battle, if not the war.

Spring Cleaning

February and early March are the time of year to do your yard and garden cleanup.  It's past the worst weather, you get a few nice sunny but cool days to enjoy the outdoors, and best of all the weeds haven't started growing yet.  Once the weather gets warm weeds will start their Spring growth with abundance.  This time of year is when you scour your yard for any trash blown in during winter storms, or left next to the shed last summer when you didn't have time to take it to the dump.  Get these things cleaned up, turn over your compost (especially if you're like me and rarely remember to turn it), pull out weeds in paths and beds while the soil is still damp and soft.  If you have landscape work to do, like laying new paths or putting in new beds, or decorative mulching this is also a great time to do those things.  Getting a head start on these chores means not having to worry about them when it's actually time to plant.  It also means getting ahead of the weeds, so you don't have to weed much before laying paths or mulch.  You can also do a quick trim of trees now, to save yourself the trouble of trying to do it when they're in full leaf or blossom.  For fruit trees this will improve your harvest, for other trees it just helps them to keep a neat appearance, and may remove diseased or broken limbs that could cause issues later.

This is the time of year to get the yard tidy and ready for the growing season.
Start at one end of your yard and work your way around the house getting everything in the best possible shape before the growing season begins.  Remove dead plant matter, maybe wash your windows and power wash the house; clean off the roof and gutters too.  Once all of this is done you will be in great shape to enjoy your yard all spring and summer, and you'll be able to plant, grow, and harvest without wishing you had washed off the siding before planting your new tea roses right in front of it.

This year I will be replacing the pebbles in the path around our house, they have gotten very thin and weeds overwhelm the path rather quickly.  Also the landing below the front porch steps needs new gravel, it has sunk a bit and now becomes a lake when it rains heavily, and grows weeds the rest of the year.  I also plan to bark mulch the open areas around my garden beds, and lay a few stepping stone paths to the shed and fountain there.  Lastly, if my budget allows for it (which it may not since I'm also remodeling my kitchen right now) I plan to rake out the lava rock around the front lawn and replace it with bark mulch, and lay in a pebbled path to the shed on the front side so my husband won't complain about getting his motorcycle through the mud to the shed anymore.

Deadheading Doesn't Mean Following Jerry Garcia Around

So say you bought a cute little pansy plant, it's brimming with blossoms, looking healthy and beautiful.  You bring it home from the nursery and gently plant it into a nice roomy pot hoping to have a large pansy plant pouring blooms over the sides of the pot in no time.

You water it daily, you add a little fertilizer when the blooms start to fade, and wait patiently for new blooms to follow in their wake.  Nothing happens.  The plant is healthy, it continues to grow, but there are very few new flowers coming and it's starting to look like a foliage plant instead of a flowering plant. 

Deadheading is the process of removing the dying blooms to encourage new flower growth.  Most gardeners already know this, and practice deadheading regularly.  More important than simply understanding that you need to deadhead your flowers is knowing why you need to, what happens if you don't, and what that translates to in other parts of the garden.

Plants are working with a limited amount of nutrients, sunlight, and water with which to grow.  Annuals have to do all of their growth, flowering, and seeding in one year.  So think about it this way, if you put a pansy seed in the ground the first thing it does is grow roots, stems and leaves; this is like a baby learning to eat before learning to walk or talk, the stems support the leaves which in turn reach to the nearest light source to feed the plant while the roots dig deep to support the growth and pull in nutrients from the soil.  So your little plant has learned to feed itself, next it will try to reproduce (luckily babies don't get a jump start on this one). Most plants reproduce by exchanging pollen between flowers, so the pretty pansy flowers you select are actually the plants sexual organs.  What lovely ovaries you have, little pansy!  Your plant develops these sexual organs in an attempt to achieve pollination (or fertilization), once a flower has been pollinated the petals will die off as they are no longer necessary to attract bees and other pollinators, and the plant must redirect it's limited energies to growing seed from the ovaries at the base of the flower.  Grow, fertilize, reproduce.  This is the basic life cycle of a plant. 

Where does the benefit of deadheading come in?  Your plant grows, puts out flowers to reproduce, then... you pluck the flowers and soon to develop seeds with them.  You have stopped the cycle, so the plant responds by trying again: reproduce! You pluck again before seed development. The flowers just keep coming as the plant struggles to meet the deadline of fall frost to have fully developed seed to grow the next season.

Apple and hazelnut trees grown out of control, pruning helps keep trees healthy.
A lot of new gardeners struggle with the concepts of deadheading, pruning, and pinching off new growth.  It's hard to accept that you need to remove healthy (and unhealthy) growth from a plant to improve it.  Even seasoned gardeners have difficulty pruning a fruit tree if they imagine all the fruits that branch might produce.  Keep in mind that growth is good, but some growth is not.  Overgrowth in a tree can cut down air flow through branches leading to mold and fungus growth, dead flowers left to seed on a annual will make it leggy and bare, and too many flowers in a tomato plant can lead to an overabundance of poor fruits. 

Remember that a plant is working with a limited nutrient supply.  Your apple tree or tomato may put on tons of flowers, but if they aren't able to pull up adequate nutrition from the soil and sun, the fruits that develop may be tasteless, small, or susceptible to pests and diseases.  Far better to trim down excess branches or flowers and ensure that the crop that reaches maturity is of the best quality.

My dad's property has an apple tree that has probably been there for eighty years, it is beautiful in full bloom.  Dad never pruned it, and insisted the fruits on it were not worth eating, several years ago one of the largest branches broke off and I helped him to remove it.  I told him it needed to be pruned, by at least 1/3 of the branches.  He was uncertain at first and was afraid it would harm the tree beyond recovery.  Finally I convinced him and we took out all but the 3 largest branches, and a few smaller ones.  The tree is still alive and I'm happy to report that the apples that year were some of the best he'd ever gotten from that tree.  Deadheading, pruning and pinching plants are methods of removing growth that impairs the plant's ability to produce the very best that it can.  Keep this in mind as you cringe and fret with pruning shears in hand.
