Plant of the Month

Some Pulmonaria have beautiful variegated foliage.

Pulmonaria -
Lungwort

Beautiful spring blooming perennials

Pulmonaria are wonderful early blooming perennials for a woodland garden or a shady to part shade border garden. Like Heuchera, they have been rather extensively hybridized for more and more striking foliage. The plain green leaves of the past have been transformed into beautiful foliage that is spotted and slashed with varying degrees of white or silver making the plant sparkle even in the shadiest corner of the garden. An added benefit -- they are deer resistant in most areas!

Beautiful blooms
In early spring, arching stems rise from the rosettes of attractive foliage producing clusters of bell flowers in shades of blue, pink, or white. These lovely flowers are welcome companions to the colorful early spring flowering bulbs
like daffodils and tulips.

Beautiful Pulmonaria welcomes spring with colorful flowers.

Versatile in the garden
Pulmonaria grow 8" to 15" tall with flower stems reaching a few inches above the foliage. They are wonderful for planting in the woodland garden under deciduous trees and shrubs. The showy leaves of the variegated forms make them suitable as specimen plants. They combine well with hosta and Heuchera as well as woodland ferns, Epimedium, and Astilbe.

Their relatively fast growth rate also makes them an excellent choice for an attractive shady ground cover. They look striking when planted in drifts with spring bulbs or lining a meandering woodland path.

Pulmonaria are perfect for woodland gardens

Culture
Pulmonaria perform best in full or part shade in rich, moist but well-drained soils. They do not like hot afternoon sun and will usually wilt under these conditions. Keep well-watered during hot dry summers to maintain fresh, perky foliage.

Exciting Cultivars
Pulmonaria 'Bertram Anderson' is an excellent choice for southern gardens where the climate tends to be more hot and humid. This cultivar has bright blue flowers and long narrow green foliage splashed with silver.
Pulmonaria 'Dark Vader' is a beautiful cultivar with a cool name!! Attractive dark green foliage is covered with contrasting silver splotches. Clusters of purple-blue and pink flowers rise over the clump in early spring.
Pulmonaria 'Raspberry Splash' forms an upright clump of narrow green leaves heavily spotted with silver. Bright raspberry-pink flowers bloom profusely in the spring!

Pulmonaria 'Raspberry Splash'

Pulmonaria 'Gaelic Spring' is a new cultivar with broad silver splashed lime green leaves. Lovely blue flowers fade to pink.

Start Seeds Indoors

Freshly planted flats of tomatoes and green peppers

For many areas, the time to start seeds is here!

Why start seeds indoors?

Starting seeds indoors allows you to have more control over the growing environment. In addition, certain pest and disease problems that plague young seedlings in the garden are avoided when plants are started indoors.

Remember to harden off transplants before they are planted out in the garden.

Cool-season vegetables to start indoors: Broccoli, cabbage, cauliflower, head lettuce, kohlrabi, Brussels sprouts

Warm-season veggies to start indoors: Tomatoes, eggplant, peppers, celery

Remember!
You need to provide a good light source for your seedlings once they germinate and you must check your seedlings each day to be sure the planting medium does not dry out.

Tip of the Month

A Diet for Plants

More and more these days we are becoming increasingly conscious about proper nutrition and what we put into our bodies; but what about our plants?

Most of the nutrients needed for the growth and development of plants are absorbed from the soil by the roots. Over the seasons, these soil nutrients become depleted and must be replenished or our garden plant health will decline.

Understanding Plant Nutrients

There are 17 chemical elements known to be essential for plant growth, flowering, and fruiting.

The primary macronutrients, nitrogen (N), phosphorus (P), and potassium (K), are used in the largest amounts by plants and are thus prone to deficiency in soils. These nutrients are the primary ingredients in most garden fertilizers and the percentages of each are prominently displayed on the bag as the N-P-K numbers. These percentages are always presented in the same order - nitrogen, phosphorus, potassium.

Nitrogen is required for healthy vegetative growth (leaves and stems) and is especially important in young plants. High levels promote dark green leafy growth but not fruits and flowers. Thus a fertilizer higher in nitrogen is great for lawns and leafy vegetables but disastrous when you are trying to grow tomatoes!

Phosphorus is important in all functions of plant growth but especially for root development and growth, and in the production of flowers, fruits, and seeds. Starter fertilizers, which can be used when transplanting trees, shrubs, and perennials, are much higher in phosphorus than nitrogen and potassium. They stimulate root growth and help avoid transplant shock. "Bloom booster" fertilizers with 50%-60% phosphorus help promote flower bud formation.

Potassium is important for the overall vigor of plants. It promotes disease resistance, root formation, and cold hardiness. Plants deficient in potassium will have weak roots and stems.

A complete fertilizer supplies all of the primary macronutrients in varying amounts. Depending on your needs, you might pick one with higher nitrogen, higher phosphorus, or higher potassium.

For lush lawns choose a fertilizer higher in nitrogen as in 32-2-8 or 16-4-8.

With the recent concern about excess phosphorus washing into our surface and groundwater, more and more lawn fertilizers are being formulated without a phosphorus component. Now you are more likely to find lawn foods with an analysis of 32-0-4 or 18-0-3 which would actually be classified as an incomplete fertilizer.

"Bloom booster" fertilizers and "starter fertilizers" are higher in phosphorus; for example 10-20-15, 10-25-12, or 15-30-15.

Espoma Potash (0-0-60)

A balanced fertilizer supplies equal amounts of each of the 3 nutrients. These fertilizers, such as 10-10-10, are often used for general applications.


Single element fertilizers (straight or incomplete fertilizers) supply only one of the primary nutrients, e.g. Espoma Urea (45-0-0), Triple Super Phosphate (0-45-0), or Potash (0-0-60).


The secondary macronutrients are calcium (Ca), magnesium (Mg), and sulfur (S). These nutrients are very important to plants but are used in smaller amounts than the three primary macronutrients.

Micronutrients, also known as trace elements, are not nutrients of lesser importance to plant health but those that are required in minute quantities. With the exception of iron and manganese, micronutrients are seldom deficient in our garden soil, however, some become unavailable to plants when the soil pH is either too high (alkaline) or too low (acidic). Maintaining your soil pH between 6.0-6.5 will keep these nutrients available to the plants. Some fertilizers are fortified with micronutrients.

Did You Know?

Choosing a Fertilizer: Organic or Synthetic

There are several ways to improve the fertility of your soil but the most common way is to apply fertilizers, either organic or synthetic (chemical fertilizer). There are advantages and disadvantages to using either form, however, in Andr�'s opinion, organics are the way to go.

Espoma Plant-tone (5-3-3)

Organic fertilizers such as the Espoma "Tones" release nutrients slowly over time. They rely on soil organisms to break the nutrients down into a form that the plants can use. Because they are slow release, they are applied less often than chemical fertilizers. Organic fertilizers are usually applied once in the spring and again in the fall. Organic fertilizers rarely burn the roots or foliage of your plants.

Synthetic fertilizers generally provide nutrients in a form that is available to the plants right away; they don't have to be broken down by soil organisms first. Although there are some slow release synthetic fertilizers, most are water soluble and release nutrients quickly. This provides a quick boost to the plants. Unfortunately, these readily available nutrients can leach out of the root zone fairly quickly so these fertilizers must usually be reapplied more frequently than organic fertilizers. In addition, excess nutrients that the plants aren't able to absorb are more likely to leach into the groundwater. Synthetic fertilizers are usually more concentrated than organic fertilizers and must be applied carefully to avoid damage to growing plants.

More Benefits to Organics

Organic fertilizers add all important organic matter to the soil, thus improving soil structure. Remember, good soil structure improves drainage in clay soils and increases the water-holding capacity of sandy soils. Some organic fertilizers including the Espoma "Tones" add beneficial microbes and mycorrhizal fungi as well as nutrients to the soil. The benefits of mycorrhizal fungi in garden soil are becoming increasingly recognized worldwide.

Espoma Bio-tone
Why add mycorrhizals?

Mycorrhizal fungi form a symbiotic relationship with plant roots to improve the uptake of water and nutrients. Tremendous numbers of mycorrhizal threads attach to the roots of plants and then fan out into the surrounding soil. These "extensions" of the root system exponentially increase the area that a plant can exploit for the raw materials needed for growth. The mycorrhizal filaments capture and assimilate nutrients, minerals, and water which can then be transferred to the plant. This relationship has been shown to greatly increase plant tolerance to drought stress and reduce transplant shock. In addition, mycorrhizals are known to secrete chemicals which dissolve hard to capture nutrients like phosphorus and iron, making them more available to plants. They even produce antibiotics which attack and kill many disease organisms that enter the "root" zone! Cool stuff!

Espoma has now incorporated mycorrhizal fungi and other beneficial microbes into many of their organic potting mixes and garden soils. The addition of Myco-tone, a proprietary blend of 11 different strains of mycorrhizae, has been proven to promote root growth, increase water uptake, and reduce drought stress and transplant shock.

Your March "To Do" List!

March is a wonderful time to be in the garden!

The days are beginning to get warmer and after a long winter, it just feels good to be outside working in the soil again. Here are some tips for getting your beds in tip-top shape for the coming growing season.

Clean your perennial beds

Rake old foliage and other debris from your garden.

Rake leaves and debris from your garden beds.
It is much easier to do this now before your spring bulbs come up and flower or the new growth begins on your perennials.
Remove last year's dead foliage from hosta, daylilies, iris, and peonies. Clear this from the garden - do not compost it as it probably harbors insects and disease. Many compost piles do not get hot enough to kill these pests and diseases.
Watch Mark's video tip.
Cut Liriope back before the new growth begins.

Trim back the the winter ravaged foliage of evergreen perennials such as Helleborus, Epimedium, and Liriope. The fresh foliage of the new season will soon be poking up and it is much easier to give them a haircut before the new growth begins. This is especially true for Liriope. Once these begin to grow in the spring, it's difficult and time consuming to trim the old foliage. Watch Mark's video tip.
Trim the winter damaged foliage of boxwood branches (browned or whitened foliage) back to live growth in mid-March.
Cut back ornamental grasses and other perennials left standing in the garden through the winter. Watch Mark's video tip.

Early spring rejuvenation pruning

American holly pruned to bare branches

March is the time to do major heavy pruning of overgrown shrubs such as holly, boxwood, azalea, rhododendron, lilac, and yew. Instead of tearing them out and replacing these overgrown shrubs, cut them back hard now while they are still dormant. Because these plants have dormant buds on the interior bare wood close to the main stem, they can be pruned heavily until just bare branches remain or you can even cut them back to one to three feet above the ground. Check Mark's pruning videos.
After severe pruning, fertilize your shrubs with Holly-tone, triple phosphate, and green sand according to the label directions.

Early spring thinning of trees and shrubs

If they need thinning, you can thin out some branches of summer flowering trees now, but do not remove more than 20% of the live branches. Remove crossing branches and all dead and damaged wood.
Forsythia blooms

You can also thin out some branches of forsythia, quince, and other spring flowering shrubs early this month while they are still dormant. Do not remove more than 10% - 20%.
DO NOT shear them (give them a haircut) or you will loose the spring bloom. Any major pruning or shearing should be done right after they finish blooming.
Watch Mark's video tip.
Wait until April to cut back Buddleia (butterfly bush) and Caryopteris.

Get a jump on pests and disease

When nighttime temperatures are forecast to remain above 40 degrees F. for 2-3 days, spray your fruit trees, roses, and other ornamental trees and shrubs with Bonide All Seasons Oil to smother overwintering insects, eggs, and immature insect stages.
Watch Mark's video tip.
If your peonies were affected by botrytis last year, spray the emerging shoots with a fungicide like Bonide Mancozeb, Bonide Copper Fungicide, or Daconil.
Always read and follow the label directions!
