The Bay Gardener by Dr. Francis Gouin

How to fight back

     Popular as Knockout roses are, they are not immune to viruses. They are susceptible to witches broom and to rose rosette, which is becoming a frequent problem. Rose rosette is spread by infested pruners and by a microscopic eriophyid mite. 

Can the Bay Gardener solve it?

About 30 years ago, I began to build up my garden with compost and leaves. Every few years, I would gather and put down about three feet of leaves to rot and be tilled into the 50-by-50-foot garden space. The garden now has a beautiful loamy soil. I have been planting with wonderful results for about 20 years.     About six years ago, I collected the leaves and put them down but did not plant for two years. I gather the bags of leaves, mostly oak, from neighboring houses. Several mulched bags of grass were in the mix this time.

Rest and replenish your bed

If you were wise enough some years back to plant asparagus, you’ve been rewarded with a spring feast. Now it’s time to give your asparagus bed a rest to ensure future harvests.     An asparagus bed planted in full sun in well-prepared and well-drained soil can remain productive for 20 years or more — if you treat it well.

Pluck off wilted flowers

For more abundant flowers on your rhododendrons and mountain laurels next year, deadhead this year’s flowers as soon as they wilt. By preventing the flowers from setting seeds, you’ll stimulate the branches to flush new growth from waiting latent buds. This is especially true if the bushes are growing in full sun.  
Last winter was hard on this easy-to-grow fruit tree — but not fatal
The winter of 2013-2014 was so severe that it killed fig trees back to the ground. Many plants also suffered severe rabbit damage at the base of the young stems with smooth bark. Rabbits eat the smooth brown bark at times when other food sources are scarce.   As we are located at the northern climatic range for growing figs, we need to anticipate winter damage at least once every 10 to 15 years. According to my records, the last time fig plants were killed back to the ground was during the winter of 1997-1998.

Time your pruning for both desirable growth and flowers

While azaleas were blooming mid-month, I passed a home in the Deale area where the bushes were so large that it must have been impossible to look out through the lower part of the front windows. They must have been sheared at some point because the middle of the plants appeared very bushy.     This is a common problem and one that is simple to correct — once you get out the pruners and get past fear. 

Plan to dig, separate, store and replant in fall

As years pass, clumps of daffodils, narcissus, jonquils and hyacinths become crowded, resulting in smaller flowers. Shrunken flowers mean it’s time to dig and replant. Wait until after all of the foliage has died back to the ground.       Mark the location and flower color of clumps to be divided before all the foliage is gone. Make a large plant label and stick it in the middle of the clump.

It’s good to eat and pretty enough for the flower garden

Asparagus is a vegetable that’s good looking enough to be planted in the flower garden. The foliage makes an excellent garden backdrop or can be used in sunny beds to give light shade to flowers that prefer partial shade.  I remember a flower garden where asparagus provided shade for an under-story planting of impatients and verbena. The effect was most attractive as the asparagus foliage created the impression of looking through a light fog.

Hoe, mulch or a touch of herbicide

The better you control weeds in the garden this year, the fewer weeds you will have next year. Weeds have the capacity of generating thousands of seeds, which means that many seeds scattered on the ground this year will be germinating next year. Not all of the seeds will germinate at once. Many hard seeds can remain in the ground for years, especially if they get buried.       Frequent light cultivation while the weed seedlings are small is the best method of control — providing you have the time.

You don’t have to wait until 2061 to delight in its offspringHill in compost to enjoy potatoes early and late

There is nothing like going into the garden and digging a nice big potato with a thin skin for dinner. A freshly harvested white potato from a plant still actively growing guarantees you not only great satisfaction but also a vegetable that is filled with vitamins because you don’t have to remove the skin to eat it.     If you plan ahead, you need not wait for the potato plant to die back to the ground before you start harvesting.
