March in the garden

This is your chance to clean up the garden without suffering from the cold. It is also an excellent time to rebuild the compost pile or build a new one if needed. Shredding all the materials in the compost will make the compost work faster and it may be ready to spread by the time the rest of the garden is ready to be planted.
There is probably a goodly supply of early weeds such as the London rocket, dandelions, salsify and other cool season weeds. If the soil is moist they are easily pulled and the roots and tops can be put into the compost pile to provide needed nitrogen for the compost. Most of those weeds are also edible if you savor their bitter flavors.
It is also a good time to remove grass that has grown into the flower or vegetable beds as the roots are now starting to send out new below ground growth.
Pull (do not cut) the dried up leaves of the iris and daylilies. Cut back the dead chrysanthemums foliage to the ground and divide them. Pot up the extras to give to friends or bring to the April plant sale at the Garden Center on the last Saturday of the month.  

Pussy willow (Salix caprea), bulbous Iris, Forsythia, Crocus, redbud (Cercis), are flowering. Bulb displays include daffodils, snowdrops (Galanthus), Triteleia (Ipheon), hyacinths (all kinds including grape hyacinths (muscaria)), paperwhites* and tulips. Also in bloom are creeping Phlox (P. subulata), Iceland poppies (Papaver nudicaule). Most fruit trees will be in bloom: apricot, plum, pear, peach, nectarine, crabapple, cherry, and quince. For the hay fever sufferers the junipers, silver maples and elms may cause torment. Allergy shots should be considered for you.

Ground covers that appear this month may include: Pink soapwort (Saponaria ocymoides), Thyme "Pink Chintz," Turkish speedwell (Veronica pectinata), and woods violets.  

Watering. Increase watering to three to four times a month if temperatures are consistently over 50 degrees and there is no natural precipitation; otherwise, continue watering as in February. After the heavy winds which we usually have in the spring and which may continue into May, irrigate to replace lost moisture. Hardy transplants can be put in now but be sure to keep them watered if there is no rain or snow. Wall of water or other season extenders can be used for some of the more tender plantings.

Pruning. Finish pruning fruit trees and summer-flowering shrubs if you have not already done so.. Start pruning roses and grape vines* late in the month. Prune Santolina native plants (chamisa, Apache plume and buffalo berry (Shephardia)), hard. Prune Mahonia, forsythia and winter jasmine after flowering. Crape myrtles bloom on new growth, so frost damage if any can be cut away once new growth appears.  Prune raspberries and other fruit-bearing bramble bushes, except for "Heritage" raspberries, which may be cut back in the fall if you are willing to forego the first crop. Often that first crop will suffer in the heat of the summer and lack of water so it may not be much of a loss.

Planting.
• Continue bare-root planting.
• Plant balled and burlapped shrubs and trees.
• Pansies, snapdragons, hollyhocks, Dianthus, carnations, statice, and stocks can go in the garden now. Most perennials can be put out this month in settled weather. Young plants from the nursery or your own seed-starting operation should be hardened off outdoors for a week or two before planting.
 
In the vegetable garden,
• set out plants of the cabbage family: Broccoli and cauliflower are at risk in the spring, as they are sensitive to extreme heat fluctuations which may come in May and will bolt before the plants have developed fully.
• Some of the early spring lettuces can be allowed to reseed or be planted in the fall for the earliest salad crops.  Continue seeding or transplanting salad greens and greens for cooking. Plant seeds of cool season growers: radishes, carrots, beets, turnips, onions, kohlrabi, parsnips, and peas.
• Plant Irish potatoes mid-March to mid-April. Start cuttings of sweet potatoes in the window or greenhouse so they will be ready after the frosts are over.
• Plant hardy herbs: parsley, sage, thyme, dill, and tarragon plants. Small herb plants from the nursery are usually quite tender and must be hardened off before planting.
• After the first day of spring, begin planting some gladiola bulbs every other week for continuous color during the summer. Dahlias can also be planted for summer bloom. If you have a protected location many other summer flowering bulbs can be planted. In such a location some can even be left in the ground over the winter with some added mulch for the extra protection from freezing.

Houseplants. The days are longer and your houseplants are beginning to wake up and grow. About mid-month, begin fertilizing houseplants. If needed, repot before you begin fertilizing. Trim roots lightly and spread them out, especially if the roots are crowded and encircling the pot. Discard old potting mix, clean the pots, and disinfect them with a 10% bleach solution before reusing. This is also the time to take cuttings of the tender bedding plants that you will want to have for planting out in May. Coleus, impatiens, plectranthus, geraniums* (pelargoniums) and similar herbaceous plants root quickly in water and can be potted up in just a few weeks time. If you have windowsill or greenhouse room pot up color bowls for placing around the house or garden when the weather is warm.

*The foliage of paperwhites will probably be badly damaged by the cold winter but the blooms will be just as fragrant and beautiful as anywhere else and superb for cutting and bringing inside.

*Most grape varieties require severe pruning in order to produce a heavy crop. Save the prunings for wreaths or make them into cuttings if you have friends who need to start new vines. See Propagation Section for how-to.

*Geraniums (pelargoniums) cuttings will root more readily if allowed to dry at least overnight before placing them in water or rooting medium.

I had an interesting discovery this afternoon as I was working in my Iris garden. As I tried to remove the left over leaves and other debris from last years plant growth ( well, they really were weeds) I saw a pile of what appeared to be snail shells. I have had snails  in my front patio over the years that had arrived with plants shipped in from California or brought in from plants purchased or given to me by some of my other gardening friends. Every year the snails become more abundant and it is either snail or slugs that eat some of the foliage in the early spring. Many years ago I had let a volunteer hackberry grow next to the fence in the back yard but when it grew too big and threatened the power line above it we decided to remove it. The trunk of that tree stayed and the large roots that spread out from the stump became infected with the mycelium of Coprinus Atramentarius better known to some gardeners as the Inky Cap and each year large clumps of the mushroom would develop from the buried roots. Last summer we had had an especially large crop of the fungus and in the fall all the snails and slugs were attracted to them as a much desired food source. Apparently cold weather arrived before the snails had the opportunity to find more hospitable quarters for the winter. So there they were. Their little empty shells bleached white over the winter. I wonder how many of them had laid their eggs in that soil and how many babies will hatch from them?  Will they devour my Iris plants when they hatch? I shall watch that flower bed very carefully this spring. Wouldn't you?
You may be interested to know that those mushrooms are edible for humans too as long as you don't drink anything alcoholic. That trait led to the discovery of Antabuse which is now used for treating alcoholism. How interesting.
