garden weeds

Weeds come in a remarkable variety of shapes and sizes.  But one thing is for sure.  We will never get rid of them all.  Their seeds can hide in the ground for many years, just waiting for us energetic gardeners to turn the soil and expose them to light so that they can germinate.  Many send out runners above ground (hawkweed) or below ground (sheep sorrel - the worst weed offender in my garden).  Others have roots so deep and persistant that they will produce a new plant from a tiny bit remaining in the ground.
Here are some of the weeds I deal with:
This is everybody's favourite - dandelion.  The plant itself lives for many years, and produces hundreds of seeds every year.  It blooms in spring, slows down in the summer, and then blooms and produces another crop of seeds in the fall.  It's best to pull this guy after a rain, when the ground is soft enough to get the whole long root.  Any root pieces left in the ground will produce a new plant, and a new headache for us.

This type of grass forms a clump which has courser, lighter-coloured leaves which stick out like a sore thumb.  The only remedy is to dig out the whole clump and re-seed with lawn seed.

Hawkweed makes up a huge percentage of my lawn.  It puts out runners which creep across the vegetable  garden and flower beds.  The yellow flowers and the seed heads look very much like dandelions.

Lamb's quarters, often afflicted by leaf miners, have more vitamin C and other nutrients than many of the vegetables we grow on purpose.

Another distiction - when is it a weed and when is it a wildflower?  This is jewelweed, which produces lovely orange spotted flowers that hummingbirds love.


Queen Anne's Lace, a wild relative of the carrot, brightens up a drainage pipe.  This plant is always alive with insects taking nectar from the flowers.  I always spare a few to pretty up a bare spot.

volunteers in the garden

Is it a volunteer or is it a weed?  When it's a plant in the wrong place, there is a fine line between the two. 
 A volunteer is a garden plant that has spread by seed or underground runner and has popped up in an unexpected place.  A weed is just that - unwanted and unloved.  With volunteers, I hesitate before I pull them out, because their effect can be unexpectedley lovely.
I never could have purposely planted this apple mint between the cracks of this retaining wall and had it flourish.  But that's exactly what it did on it's own.

This pumpkin is a volunteer that sprang from a seed from a volunteer pumpkin that appeared in my garden last year. Welcome back!

When putting together my containers, I ran out of purchased soil, and topped off this container with soil from the garden.  Out popped a tomato seed that had waited all winter in the cold ground. 

I planted one sumac a few years ago.  Now they are popping up all over the lawn.  I hope to have a mini forest soon.  They are easy to snip off if they become too many to be a good thing.





Volunteers are not always a good thing.  This is a sunberry seedling, full of flea beetle holes, but thriving.  Three years ago, I started sunberries indoors from seed, carefully planted them outside, and was rewarded with a bountiful harvest of black berries that tasted awful.  And I have been pulling out seedlings ever since.

The best time to plant a tree is 20 years ago

The next best time to plant a tree is today!  One of my norway maples died, and after wrestling with a hand saw to cut it down, I figured it was a perfect time to plant something a whole lot more fun and interesting.  Buying a tree in August means there is not a lot of selection left.  But I was happily surprized to find a bunch of Sunburst Thornless Honeylocust (Gleditsia triacanthos var. inermis 'Suncole').  These trees are quite graceful, and their branches droom artfully.  
Being August, the trees were not in the best shape, and with much hemming and hawing, I picked the least damaged specimine.  We stuffed the pot between the front seats, and the top branches hung out the back of the car.  Covered in plastic to reduce wear and tear, we got it home. 
Water well while still in the pot, so that the water leaks out the bottom.  Cut off any bushy growth at the base of the tree or anywhere you don't want a branch to form.  
Picking a location for a new tree isn't easy, because you know it will be something to look at for many years to come.  I picked a spot beside the stump of the old tree.  I marked out a circle about 3 feet in diameter, stripped off the soil, and started to dig.  With so little rain this year, the soil was like concrete.  The digging was a slow process.   
The hole should be as deep as the pot, and at least twice as wide.  Set the tree in the hole and lay a shovel across to determine if the depth is level with the base of the tree.  Then loosen the soil in the bottom of the hole, fill it half full of water, and let it drain.  Gently pop the roots out of the pot (this might take some doing), tuck the tree into the hole, and if it was pot bound, loosen the roots.  Set the tree so its best side is facing the way it will be seen.  Water the hole again, put half the soil back in the hole, tamp it down, water again, and add more soil.  Don't amend the soil with good stuff, because the roots will not want to travel away from the rich soil, and the tree won't become well established. 
Top off the planting with mulch to keep the soil moist.  Support the tree for the first year.  After I got it planted, I noticed that I missed trimming a dead branch.  Now that it's in the ground, it's too high to reach.  Since it has been so dry here, I make sure to give the tree a gallon of water every day.  It looks pretty scraggly, but I'm pleased with the result.
