April in the Garden in the Santa Cruz Mountains

Spring might have officially started mid-March but judging from the wonky weather it’s hard to tell. We did experience a ?Miracle March?? with a pretty good dose of needed rainfall along with some very cold weather. You never know what to expect in March around here.

But now we?ve turned the corner on spring with flowers bursting open within hours on these nice days. The Black-headed grosbeaks have returned to my yard for the breeding season. Like clockwork they show up on almost the exact day each year. It?s my version of the swallows returning to San Juan Capistrano.

Looking forward to the rest of spring, here?s what I?ll be doing around here in April.

Hopefully we?ll have plenty of April showers. This latest rainfall is surely? welcomed. One of the perks of a cool, rainy spring is that shrubs and perennials have longer to establish a good root system before hot weather arrives, ground covers have time to spread and shade the soil, conserving moisture come summer. What strategies can you follow that will make your garden low maintenance this summer and give you extra time to enjoy it?

Plant in masses. When designing or reworking your garden, make it

easy on yourself by planting fewer varieties but in greater numbers. Planting this way will reduce the number of different maintenance tasks for that area. For example, if you have a large hillside that you want to cover, plant it with a groundcover like ceanothus gloriosus which fans out 6-15 feet. Some manzanitas like arctotaphylos uva-ursi eventually spread to15 feet each. Sage leaf rockrose and germander are also good for sunny areas. A shady spot could be planted with ajuga, creeping mahonia or Walkabout Sunset lysimachia.

Another time saving strategy is to group plants with similar moisture needs. This may sound like a no brainer but if you have just one prima donna in a bed of more drought tolerant plants, you’ll be dragging the hose over to that bed for just one plant or having to run your irrigation system more for it. If you find that some of your plants are not quite as low water as you’d like, move those to their own spot. In general, plants with large leaves usually require more water and transpire faster while drought tolerant plants typically have one of more of the following characteristics: deep taproots and leaves that are smaller, silver, fuzzy or succulent.

Avoid putting thirsty plants in hard-to-reach places. If the irrigation system doesn’t reach that far, keep it simple by planting drought tolerant woody shrubs or perennials there.

Pluck weeds when the soil is moist and before they have gone to seed. Even if you don’t get the entire root of more persistent weeds, just keep pulling at the new growth. Eventually, the plant will give up having used up all of the food stored in its roots. I?m still battling hedge parsley with it?s sticky seed balls that will cling to my shoelaces and the dog?s fur if I don?t get it before it sets seed.

Plant edibles among your other plants near the kitchen. Tricolor sage looks great alongside other plants with pink and violet leaves. Purple basil planted below the silver foliage of an artichoke is another great combination. Lemon thyme growing next to a burgundy colored dwarf New Zealand flax would look spectacular, too. And don’t forget to plant decorative and delicious Bright Lights swiss chard with its stalks of yellow, orange, pink, purple, red, green and white throughout your beds. It?s one of the easiest vegetables to grow.

So get the lemonade ready to enjoy all your free time later this season.

What Makes for a Sustainable Garden?

The redbud are just starting to show color in my yard. Flowering plum, tulip magnolia, manzanita, forsythia, flowering currant and quince are blooming in many a garden. Even the deciduous trees and plants that look bare now are starting to grow new roots deep underground. It’s time to plan this year’s garden. Think about how you can blend artistry with ecology.

Garden to attract birds, bees, butterflies and other beneficial insects

A landscape developed with sustainable practices will improve the environment by conserving resources. It will require less maintenance and fertilizing, be balanced with our climate in mind and use less pesticides and water. Most of all it will be visually pleasing with lots of flowers. bees and butterflies.

Your goal may be a more drought tolerant garden but which plants are right for your yard? What plants will be more likely to withstand disease and pest damage? What kind of irrigation system should be installed to provide for the needs of the landscape in the most efficient way possible? Is it time to convert your sprinkler system to smart drip, inline drip emitters and micro-irrigation?

Where do you put the compost bin so you can return garden waste and kitchen waste back to the garden while recycling nutrients within the landscape? How do you keep the soil healthy? There are many components in designing and installing a sustainable landscape that is just right for your garden.

Start with a smart design. Utilize permeable paving like gravel or pavers to help manage runoff, giving the soil more time to absorb rainfall and recharge the ground water. Maybe you need a rain garden or small planted basin to catch and filter rainwater and keep it onsite.

Planting bed of plants with similar watering needs.

Group plants in your garden according to their water needs. Now?s the time to transplant if necessary to achieve this. Some maybe can survive on rainfall alone after their second or third season while the perennial beds and vegetable garden will require a different schedule. Water slowly, deeply and infrequently so there is no runoff. Water in early morning or evening to maximize absorption.

Plant deciduous trees to provide cooling shade in the summer and allow sunlight to warm the house in winter. Trees and shrubs clean the air of nitrogen, sulfur dioxide, ozone and carbon monoxide. They breathe in carbon dioxide, a major greenhouse gas, use the carbon to grow, then exhale oxygen. They retain more carbon than they lose so every tree you plant helps reduce your carbon footprint on the planet.

Feed and shelter birds, butterflies and other wildlife in your landscape. Plant perennials such as echinacea, lavender, penstemon or salvia, ceanothus and other native plants to attract pollinators like bees and hummingbirds. Plant flowers that attract beneficial insects to help control harmful insects and use organic pesticides.

Make your soil a priority by adding compost each year. Mulch your soil to keep down weeds and conserve water and use organic fertilizers, manure and fish emulsion that feed the soil. Compost the green and brown waste your garden produces like fallen leaves, weeds without seeds, grass clippings, spent flowers and vegetables.
Stay ahead of weeds, pulling them before they set seed and spread.

Take steps each year to encourage a beautiful, sustainable landscape and make your corner of the world part of the solution.

Sheet Mulch Away that Old Lawn

Replacing that water guzzling lawn or dramatically reducing the size is a good place to start conserving water and is easier than you think. If you?ve been paralyzed with the thought of digging out and hauling away hundreds of square feet of heavy sod or using dangerous grass-killing chemicals, sheet mulching is the method for you.

This simple technique eliminates the lawn by smothering it with layers of compost and renewable materials. Here?s how to do it:

  1. Mow the lawn down to 1-2?, leave the clippings in place and soak with a hose.
  2. Flag the locations of sprinkler heads you will be keeping for your new plantings and cap off the ones you won?t need.
  3. Add an inch of compost to speed up the decay of the grass. If your lawn borders a driveway, path or sidewalk you?ll have to remove about 3? inches deep of soil along these edges and back 8-12? so that the new mulch doesn?t slide off into the sidewalk.
  4. Put down 2-3 layers of newspaper or one layer of cardboard overlapping the edges by 6-8? to prevent regrowth at the edges. You can buy recycled cardboard in rolls for larger projects or find your own at appliance or bicycle stores. Wet the cardboard or newspapers to keep them in place as you go along. It?s best to use cardboard or newspaper thatwill break down quicker. Don?t use plastic sheeting because water and air cannot penetrate it.
  5. Add a 3? layer of mulch such as bark chips from a tree trimming company. You can use compost, straw or shredded plant material. If you have Bermuda grass or other weeds like oxalis you will need to layer about 8? of mulch to smother them.
  6. Water thoroughly.

If you can wait a month or more to let the decomposition process get going so much the better. If you just can?t wait you can begin planting now by scraping away the mulch and poking a hole in the cardboard or newspaper where the plant is to go. Then add some compost to help the new plant become established. Be sure to plant high enough to prevent crown rot and keep the mulch a couple inches away from the stem. The top of the root ball should be 1-2? above the soil and just below the mulch.

Modify the sprinkler to drip and remember to adjust your irrigation system run times to accommodate your new plantings.

This is a basic ?lasagna? method for lawn removal. If you are planning to replant with water smart grasses you would choose finer composted mulch instead of bark chips. Either way the process works on the same concept as a compost pile. As the lawn dies from lack of light, it decomposes with the activity of beneficial worms, insects and microorganisms coming up from the soil and doing their job to break down the nitrogen and carbon in the sheet-mulch layers. It?s a win-win situation for the environment and your water bill.

Water conservation starts with losing or reducing the thirsty traditional lawn and reducing irrigation. Transform your landscape into a resilient garden that not only saves water but acts to build the earth into a living sponge that harnesses rainwater and replenishes the aquifer at the same time. Attracting wildlife to your new beautiful garden is a bonus.

Be sure to apply for your rebates and have your lawn inspected, even if it?s dead, before you start.
