Perhaps no other single plant or tree can add as much value to a garden landscape as a Japanese maple. They look great planted as a centerpiece in mounds or garden islands, plus they make excellent container plants for a patio or terrace. Japanese maples are also used quite extensively as bonsai specimens.

What makes this tree so popular is that it is available in many sizes, colors, leaf shapes, and growing habits. The color of Japanese maples ranges from bright green and variegated to shades of orange, red, and purple. The fall foliage on most varieties is beautiful. You can find single-stemmed specimens, multi-trunk, and low-growing mounded varieties.

This versatile tree can be planted any time of the year in most regions of the U.S., as long as the soil is not soggy. They require a location with good drainage and prefer protection from the wind. Avoid planting them in lawn areas, because lawns receive more frequent watering than Japanese maples require. Use red- and purple-shaded varieties against light-colored fences and walls, or to set off other plants. Use green-leafed varieties in shadier areas, against plain fences or darker shaded walls.

Most Japanese maples prefer a morning sun/afternoon shade or full shade location but will acclimate quite well after a few years planted in full sun, provided the soil around them is kept consistently moist. The key to watering Japanese maples is slow, deep and regular waterings. Never let the tree dry out. The soil should be kept moist, not wet.

Japanese maples are not heavy feeders, and can burn from too much or too strong a plant food. We recommend feeding twice a year during the growing season with Dr. Earth Organic 4 Azalea & Camellia Fertilizer. It is important not to cultivate around the root zone. A 2" layer of mulch such as Master Nursery Acid Planting Mix will help keep the upper layer of soil moist and help prevent soil crusting and weeds.

Planting
Bedding plants/annuals will soon be available within the next few weeks to replace any cool-season annuals that are just about done. Zinnia, ageratum, coleus, dahlia, marigold, nicotiana, phlox, petunia, verbena, salvia are in season. Also, try some taller annuals such as cosmos, cleome, sunflowers, delphinium, and foxgloves to add height and interest to the garden beds.

There's still time to plant roses. They are full of buds and blooms right now--and they are simply gorgeous

If you are a beneficial insect lover, flat-topped flowers like Shasta daisies, scabiosa, strawflowers, and yarrow are perfect additions to your garden for feeding them. Beneficial insects such as the almost microscopic parasitic wasps, ladybugs, etc. keep other insect pests away from your vegetable gardens by eating aphids, scale, and other annoying intruders. You can use beautiful flowers to tempt these garden friends into your garden. Try putting some of these flowers near to your rose garden for aphid control!

The narcissus and daffodils are blooming, as well as other spring blooming bulbs. However, as soon as the blooms are spent, you can deadhead--but don't remove the foliage! The bulb needs that green foliage to add nutrients back to the bulb for next year's flowers. Hide the clippers for a little while longer. Try and old-fashioned technique of braiding the leaves. If you must cut, leave at least half of the leaf length for the bulb. It will thank you with next year's bloom!

It's time to start warm season crops. Coastal areas can continue planting cool season crops like the leaf lettuces, radishes, and spinach for a while. Inland zones (not the high desert, though) can start the warm season vegetables such as beans, corn, squashes, cucumber, eggplant, tomatoes and peppers. We have them all and more.

Maintenance
Continue with fertilizing those areas of the garden you haven't gotten to yet. Once your azaleas and camellias have stopped blooming their hearts out, they will thank you if you feed them. This is a good time to prune back these two spring bloomers. Once the flowering has ended and before the new growth begins, prune and shape to your desired shape and size.

You may see some chlorosis on your acid-loving plants like the azalea or camellia, and possibly on your citrus. This yellowing of the leaves between the veins is a sign of iron deficiency for the plant. Feed with a good iron supplement such as Master Nursery Iron Plus.

Especially near the coast, this is the time we begin to see powdery mildew on our rose foliage (and other plants too). There are several different foliar fungicidal sprays to that can help, like Serenade Garden Disease Control.

Aphids will be back. Remember that you can first wash them off with water. Really, it does help. For more severe infestations, ask us to recommend something suitable for your particular plants.

Continue to replenish your mulch and maintain a 2-4" blanket over your soil.

When most people think of annuals they think about upright varieties for borders and containers. But when planning your annual garden, think about more than just upright plants. There are a number of wonderful trailing varieties that are perfect for providing a splash of color between shrubs, on a hillside or cascading over a rock wall or trailing from a hanging basket.

For a hillside, it's hard to beat trailing lantana, with its showy purple and white blooms. A happy plant can reach 3-4 ft across in diameter. If you are looking for a slightly flatter foliage that hugs the ground, consider the mauve-flowering scaevola.

It's easy to perk up your landscape by planting patches of million bells (callibrachoa) in spaces between larger shrubs. This colorful annual comes in a variety of bright hot colors including red, yellow, apricot, white, pink, fuchsia, blue, and violet. Another alternative would be verbena, which is available in many colors, flower sizes and flat or mounding foliage. These plants also look great flowing over rock walls or pool edges.

For large splashes of color in the landscape, use petunias or ivy geranium. Both grow incredibly fast and come in every color under the sun. You can dress up the edges of a boring-looking vegetable garden with nasturtium, whose orange, red and yellow flowers are also edible.

All of the above mentioned plants perform well in hanging baskets but there are a few plants that make great partners with them and are particularly suited for container planting. To add some texture and unique foliage color to your hanging baskets consider using silver dichondra, licorice plant (helichrysum) or parrot's beak (Lotus maculatus). All have silvery grey foliage that provides a great contrast to other plants.

While most plants in hanging baskets perform better with a little shade from the afternoon sun, one annual is particularly suited for slightly shadier confines. Use trailing lobelia, which comes in many shades of blue, rose and white. Its cheerful little blossoms are perfect for any container.

Spring is around the corner. The cool season grasses such as fescue, ryegrass, and bluegrass are those lawns over which people have exclaimed, "You look marvelous!" (Can't you just hear Billy Crystal?) They have been bright green all winter. They are still growing fast; mow them weekly with a rotary mower (to 1 1/2 inches in height).

You should be feeding all established lawns now with a complete lawn fertilizer--containing phosphorus and potassium as well as nitrogen--to get warm-season grasses off to a good start and keep cool-season grasses going longer. A healthy, well-fed lawn is better able to withstand pests and diseases and choke out weeds

Warm-season grasses, such as Bermuda, St. Augustine, and zoysia, are waking up from winter dormancy. As they start growing, begin mowing weekly with a reel mower to the correct height for each. Mow common Bermuda to 1 inch, hybrid Bermuda to 1/2 or 1/4 inch, St. Augustine to between 3/4 and 1 1/4 inches, and zoysia to 3/4 to 1 inch height.

We have mentioned two different kinds of lawn mowers: rotary and reel. A rotary mower is one in which one blade spins horizontally and uses a sucking and tearing action to cut the blades of grass. A reel mower is one in which the blades spin vertically and use a scissoring action to cut the blades of grass.

You notice that we recommend fertilizing with a complete fertilizer (we recommend Dr. Earth Super Natural Lawn Fertilizer for most lawns). While nitrogen gives your lawn top growth and a healthy green color you can see, phosphorus and potassium feed the roots and growth systems of the plant that are unseen but just as important. Phosphorus and potassium are longer lasting in soil than nitrogen, so one feeding a season with them is often adequate. After this complete feeding, you can switch to a less expensive, pure nitrogen fertilizer if desired, and feed warm-season grasses with it once a month for the rest of the growing season.

Before applying your complete fertilizer, be sure to read the instructions for your lawn type. Apply fertilizer when the ground is damp and grass blades dry, and follow up by watering deeply. Otherwise, you risk burning your lawn. As an alternative fertilizer for the cool season lawn, add coated slow-release fertilizer. Cool-season grasses need little or no fertilizer during the warmer months of the year. Slow release fertilizer will work perfectly for this type of lawn.

Irrigate all lawns now, according to their individual needs.

Both warm and cool-season grasses are available as sod. Planting sod now will give it more time to establish a root system before summer heat arrives. Although you can plant both warm- and cool-season grasses from seed this month, fall is actually a better time to plant cool-season grass seed. This is because fall planting gives cool-season grasses planted from seed more time to establish a root system before summer heat arrives. When planting warm-season grasses, wait until the weather has warmed up in your area. (If you plan to plant zoysia, it's best to wait until June.)

There are numerous lawn types and you should investigate each of them before choosing and planting one. How do you choose which grass is right for you? There are many considerations: sun, shade, foot traffic, pets, children, hardiness, style, color, and simply the 'look' that you like.

When planting a new lawn, regardless of the type of grass and method of planting you choose, be sure to prepare the site thoroughly. If you're planting an invasive grass, such as Bermuda or an invasive variety of zoysia, first install edging to keep it from creeping into borders.

For all lawns, roto-till deeply, add plenty of soil amendment, then level and roll this amended ground. "Level" might mean rolling the area completely flat or it may mean compacting the soil but adding mounded areas of interest. The point is to level out soil so that your new lawn is not filled with hundreds of hills and valleys that would make walking on it (and mowing it) difficult.

If you have chosen to put in a seed lawn, sprinkle seeds evenly. This is most efficiently done using a hand-held fertilizer spreader or a seed spreader and covering the seeds with mulch or a lawn topper product.

Just water and watch. In a few months--voilà--your new lawn!

How do I know if I have poor drainage?

Answer:

First, your plants won't look happy. (Surprise!) The foliage will look dull and lack the luster and intense color of a healthy plant. If it is a blooming plant, it may produce few blooms or none at all. When the condition becomes severe, the plant will drop its leaves from the interior first, eventually working its way to the leaf tips.

The second sure sign is if you are not watering much but the ground stays continually wet, or even has moss or algae growing on it. The soil may also have an odor. What is important to remember is that every time plants are watered, the soil temperature is lowered by up to twenty degrees. Most plants are stimulated to grow as the soil temperature warms up. If the soil is always wet, the soil temperature will be cooler than the plant desires and it won't grow much.

Poorly draining soil also attracts bad bacteria that can attack the root system, in addition to providing less oxygen for the plant. If you think you have bad drainage, gently lift the plant out of the ground with a shovel--being careful not to damage roots.

If the soil is wet at the bottom of the hole, dig it deeper and back-fill with at least six inches of gravel. Then build a mound that will raise the plant 3-6 inches higher than the surrounding soil level and re-plant so that the top of the root ball is level with the top of the mound. If that doesn't work, you may need to find a different location for the plant.
