native news spring / summer 2008


hello friends, 

What a lovely spring we've had -- I love seeing all those apricot-orange monkeyflowers blooming all over the Santa Monica Mountains. The exuberant colors of coastal wildflowers remind me that despite rush hour traffic and urban sprawl, Los Angeles still offers simple joy in its natural beauty. Even as some blooms begin to fade, there are still more many to gain inspiration from -- in the garden, on hikes, and even from the window of a car. Locally, I've been enjoying the bright purple lupines, fragrantly flowering sages, and dudleya in flower on rocky canyon walls. In my own garden, this year's poppies have gone to seed, but the bush sunflower, columbine, and elegant clarkia (pictured above left) are still out in full glory.

Soon rising temperatures will signal an end to the pageant of spring wildflowers. Although I'm always sorry to see the flowers disappear, it will soon be an ideal season to embrace the lazy gardener within. That's right, the delicious laziness that goes hand in hand with summer is actually a virtue if you garden with California native plants! Aside from adding a layer of mulch to keep roots cool in the heat, and some "little sips" of early morning water for the garden, many native landscapes require little attention during the summer. That makes the hottest months from June through September a perfect time to sip a cool drink, kick up your feet, and dream up your ideas for establishing new natives in the fall.

Like many native plants, Native Spaces Garden Design will be dormant during the summer months. We'll be off from mid-June through September germinating plans for fall gardens. We look forward to gardening with you in September. As always, check out our website for garden ideas and inspiration: www.nativespacesdesign.com

Thanks to all of you who stopped by during this spring's garden tours -- I had a great time meeting so many passionate garden enthusiasts.

Cheers!

must mulch

If you haven't done so yet, now is the time to add a top layer of mulch to your garden before the summer heats up. Doing so will:

- keep roots cool
- reduce soil moisture loss due to evaporation
- prevent soil erosion
- add an attractive, finished look to your garden

When applying mulch, be sure to leave a few inches of room around the plant's base mulch-free to prevent root rot. 

Mulches come in many varieties so have fun experimenting. Bark chips slowly add nutrients to the soil as they break down, decomposed granite works well in desert-themed gardens, and river pebbles add a zen-influenced aesthetic. 

we love gypsum for our clay soil!

what it is: Calcium sulfate. Gypsum is a soil amendment, not a fertilizer.
benefits: It improves many qualities of the soil it is applied to: it increases water infiltration (and thereby decreases runoff and erosion), allows problem nutrients to be leached away, buffers soil pH, and improves the structure of clay soils. 
how it works: Calcium sulfate makes sodium soluble so it separates from soil particles. Treated soil is "loosened" so that root hairs can feed on all available nutrients and moisture.
how to use it: Follow the manufacturer's guidelines, of course. We like to apply a yearly top dressing of gypsum, and then spread mulch on top of that, and water well.
why we like it: Gypsum is an inexpensive, non-toxic soil amendment that is widely available and is approved by the International Federation of Organic Agriculture Movements (IFOAM).
remember: Gypsum is especially helpful for hard clay soils, but it doesn't work overnight. It can take up to three years for full effects to take hold.
