Prune spring flowering shrubs when they have finished blooming. IMG_6128 Be very careful with rhododendrons and azaleas, as it’s very easy to remove next years bloom.  If you can just leave them, it would probably be best.

Thin seedlings

Use balanced, organic fertilizers around flowers

Be sure to fertilize your annuals with liquid fertilizer. They’ll thank you for it by blooming continuously!

Stake tall perennials, like lilies, and Foxglove.

Are your tomatoes “caged”?  If not, get that done before it’s too late.

Use a pine needle mulch for blueberries

Be sure your lawn mower is set to cut the grass HIGH

IMG_7570Be sure to dead-head those iris, and remember the time to divide them comes next month.

Gladiolus corms can be planted-alternate their planting by two weeks or so.  That way they will bloom continuously.

Dead-head (prune off) spent flowers from plants and shrubs

Remove rhubarb seed stalks as they form.

Cutting back perennials such as dianthus, veronica and other similar shrubby varieties, will possibly produce a second blooming. How great would that be? They’ll also look better!

You can make softwood cuttings of shrubs this month through July.  Using a little rooting hormone would facilitate the process.

You may still plant container grown shrubs

Plant broccoli seed for fall harvest.

If you have a water garden, there’s still time to plant water
lilies.

House plants can be moved outside to a shady, protected spot.

These same houseplants can be lightly fed with half strength
fertilizer.

Mulch perennials and roses to keep down weeds and conserve moisture.

If you have an amaryllis, now would be the time to move it outside.

Pinch the leading stems of your chrysanthemum’s to encourage them to
be bushier and have more blossoms. Continue doing this every 6 inches
or so, as they grow.

If you have apple trees, hang red sticky-ball traps to control apple maggot flies. Small trees can get by with 2 balls. Larger trees should probably have 4-6 balls.

Stop cutting asparagus when the new spears get pinkie-finger thin. Let them grow into ferns instead. It will feed the roots.

Side-Dress veggies to give them a little boost

Have you got Hostas? IMG_7586Are there slugs chewing them? Try this solution, if you haven’t already.
Combine 9 parts water to 1 part common household ammonia and spray it on the hosta just before dark. When the slugs hit this, they will dissolve!

Are you remembering to turn the compost every once in a while? You should also wet it down if the hose is close by. Doing this will help it decompose quicker although it will eventually happen anyway!

Mow down any daffodil drifts that have “gone by”, if you haven’t already!

Order your bulbs so they arrive in time to plant in the autumn.

Today, after lunch, since I was in the Dining Room and half way to the gardens, I thought I’d take a little swing through them to see what was peeking up.  I was NOT disappointed!  In fact, after I waltzed through the 3 levels, I went upstairs and got my little iPod-Touch (my camera!) and went back to take some pictures of the rhododendrons.  They are VERY pregnant with blooms, IMG_7211and I thought that justified a blog posting about how to deal with rhododendrons, or rhodies, as I call them.

Over the next month these plants will bloom, and bloom and bloom.  They are among the most prolific and beautiful blossoms you will find in our gardens.IMG_7214IMG_7213

Now, how do you care for them?  They are really pretty easy.  Here are some basic points to think about:

  • DO NOT PRUNE UNTIL THEY ARE DONE BLOOMING.  If you do, you will rob us all of beautiful flowers!  If you want to pick some of your own blooms for use inside, that is of course your privilege.  Do NOT pick blooms from any one else’s garden however!  (Unless you have permission.)
  • Prune sparingly.  Try to remove ONLY dead and diseased plant material.  If the shrub really needs to be brought under control, size-wise, or if they are looking “leggy”, it’s easy to do by pruning right down as close to a parent branch as possible.  You will get new shoots, which will be blooming in a couple of years.
  • These plants bloom so prolifically that they often exhaust themselves trying to produce seed from all those blossoms.  If you are careful, you can remove the spent blossoms.  However, be careful to take ONLY the spent bloom, and NOT the leaves surrounding them, as that is where next years blossoms form.  If you are feeling timid about this, just leave them alone.  Then when they are completely dry, you can almost brush them off!  Or still leave them alone, the plant will be just fine.  Some wild plants are NEVER pruned and they continue to bloom as if they were being paid for it!!!IMG_7206
  • Here is a Washington State Extension article about pruning your rhodie.  It has more links associated with the page.  Click away!
  • Fertilize them?  They naturally grow in the woods, with no need for extra fertilizer.  They love partial shade, as well as all the needles and leaves that coat the forest floor.  Keep that in mind!
  • Do they need extra water?  Probably not.  As long as they have rich soil and good mulch they should do fine.  If we have a REALLY dry spell, they would probably be grateful for a DEEP watering.  They are shallow rooted, so if you don’t water them deeply, the roots will head toward the top of the soil to get that water, making them vulnerable to heat and dryness.IMG_7210

Here is a PDF from Washington State Extension Service.  It tells about a myriad of issues that can take down your rhodies and azaleas.  Don’t let the article scare you off.  It looks pretty dramatic.  BUT, if you DO have a problem with your shrub, there are great pictures here of what the affected plants and leaves look like, and then you can deal with the problem.  Click on the link to see the information.

Now, notice how healthy all the rhodies look in the photo’s I took today?  Our plants are doing quite well, and you probably won’t have ANY of those difficulties…so don’t worry about it!

At any rate, enjoy the rhododendrons as they fill our gardens with a profusion of wonderful color and cheer!  All of our gardeners are HOPING you go down to the garden terraces and just “hang out” there!

There was also a clump of Hellebores blooming away…here they are!IMG_7209
