“It’s All About Bulbs”

You may remember in late September I wrote about planting bulbs. I don’t usually advertise here on RLGS, but this is a hard-to-beat offer. If you live in Metro Vancouver, Botanus (Langley) is having a massive sale on Saturday. I’d be there myself, but it’s the one Saturday in the year that I’m over in Nanaimo. So the rest of you have a better chance to get what you want.

Plan Your Spring Garden Now

Here are a few design tips for your early spring garden.

TIP #1–It’s all about BULBS!

Fritillaria meleagris

There are some things that bloom really early in the year– Witch hazel (Hamemellis) and some of the Rhodos in January, Sweet Box (Sarcococca) and Edgeworthia in February– but for simple delight, you can’t beat BULBS. Snowdrops (Galanthus) are earliest, then crocus, grape hyacinths (Muscari), chionodoxa, reticulate iris, then daffs,  botanical tulips, fritillary, then late daffs and late tulips, and latest of all, alliums. (I’ve left out lots, so just check out your local nursery.) You can reliably have blooms from bulbs February to June! (There are some very late alliums that bloom in July-Aug!)

DRIFTS

Either Tulipa tarda or T turkestanica

2. Plant in “drifts”. It’s often said you should plant identical things in odd numbers, but of course once you’re above 5 or 7, it’s a moot point. Who’s going to count? Because each bulb only results in one bloom (usually), you’ll want to plant many of any one species or colour in order to appreciate the impact.

SQUIRRELS

3. Remember your garden “guests”. Squirrels LOVE bulbs. But they don’t like daffs, and they don’t like to have to dig too deeply. So there are a few things you can do to deter squirrels: You can plant the bulbs deeper than the package instructs. Generally you plant a bulb 3-5 times it’s own depth. So a 1″ tulip would be planted so the base of it is 3-5″ below ground level. Go with the 5″, and make sure you don’t underestimate. If the bulb is a bit deeper than it’s 5x depth, it will still come up, maybe just a little later. For smaller bulbs that necessarily will be closer to the surface, and easier for squirrels to access, I like to cover them with a patch of chicken wire; the shoots will come through the spaces, but the squirrels will be stumped! And finally, if you’re not fussed about “purity”, throwing the odd daff into your other bulb drifts will deter the squirrels from the whole lot. Nice.

LAYERS

4. Plant bulbs in layers. This is especially effective in containers, but will work everywhere. You’ve got bulbs that blooms at different times, and different size bulbs (hence different depths of planting). Perfect. Not only will you get more bang for the space, but the later growing shoots will hide the fading foliage of earlier blooms.

Important point: when the blooms of any of your bulbs have faded, DON’T cut back or in any other way interfere with the green foliage. (Unless of course you’re treating your bulbs as annuals and will replace them every year. Maybe fine for the hort department of your city, but IMO not for the home gardener.) The leaves are still photosynthesizing and supplying growth nutrition to the bulb. 

FOLIAGE

5. Locate your bulb drifts where other perennials will grow up and hide the faded foliage. In most cases the bulbs will be coming up before your herbaceous perennials begin to waken from their long winter’s nap, so they are the stars of the show. But not so beautiful when the blooms die off. You can cut off the flower stem and leave the foliage, and soon your echinaceas and shasta daisies and hostas will spring up. A variant of this principle is to grow them under deciduous shrubs. Until the shrub leafs out, the ground is in full sun for your bulbs; when the foliage is looking tatty the shrub has filled out. DSCN1027

This is the same spot as the picture at the top of the post. Grasses, lilies and (not visible in the picture but off to the left) coreopsis--all hiding the tulip leaves. I won't bother cutting them off, they'll be compost by the end of the year.

One great thing about gardening in coastal BC is the length of our Fall–it really goes almost to Spring! Now is the time to plant your Spring bulbs, but if you forget this month, there’s still next month–October. And November. And December. But why wait–do it now.

 

 

 

Tips for Post-Spring Clean-up

DSCN1027Your crocuses and daffs and tulips were lovely, but now they’re just a mess.

The candytuft really filled the space, but now it’s all just one big mess.

The early peonies were bright and bold, but now they’re really a mess.

What to do? Cut, cut, cut. But cut with care!

Let’s Start With Peonies

I didn't stake these up, so this is the consequence. I managed to cut a few for a bouquet before losing the rest.

You can cut off the flower stalk, but leave the rest of the foliage. It’s lovely right now, will furnish cuttings for bouquets through the rest of the growing season, and will probably turn a bit red in the fall before they finally succumb. A lot of your larger non-bulb spring plants can be treated the same.

Spring blooming bulbs and rhizomes

Most of your bulbs need to continue to grow and photosynthesize even after the         flower fades in order to replenish the bulb, and in some cases multiply the bulb. So you can cut the flower stalk and leave the foliage until it turns completely yellow. Problem is, of course, it begins to look unsightly pretty soon after the flowers are done. Your best solution is to plant bulbs in among other perennials that will grow up alongside, or soon after the bulb, so the new growth of the companion plant hides the dying foliage of the bulb.

Irises (a rhizome) are easier because they maintain their sword-like foliage into the late fall. All you have to do is cut down the flower stalk.

Last bloom of the irises--can be sacrificed for the sake of getting rid of the unsightly stalks.

Some faded flowers are definitely worth keeping. This allium (‘Purple Sensation’) is setting seed, and usually that means that it isn’t putting it’s energy into replenishing its bulb. But why cut down something that looks this good?

Ground cover

Aubretia, Creeping Phlox, Iberis–all ground covers that bloom like crazy in the spring, then really NEED to be trimmed after blooming so they’ll maintain a nice neat growth habit. Otherwise they get woody, or sprawl all over the place, or grow out the ends and die in the middle. Trimming is exactly what it sounds like–grab a handful and CUT.

You can just see (it's ll the same green unfortunately) the faded flower stalks that are setting seed.

I've taken a good handful here and I'm cutting well below the beginning of the faded flowers, leaving just a bit of old growth. It'll grow back in no time, and increase in size.

Most of your similar low-growing spring bloomers can be handled the same.
