The Bay Gardener by Dr. Francis Gouin

Three months of The Bay Gardener’s advice on planting, pruning and lawn care

   ~ April ~      Grow a No-Till Garden     Start your garden as soon as you can work the soil, certainly in April if not already in March.     Do not spade. Save your back and your soil by planting no-till.

Please don’t crape murder it

I find crape myrtle 10 times more attractive than white birch trees, which we in New Hampshire consider a weed but Marylanders insist on trying to grow against the odds. It is a waste of time and money to plant white birch in southern Maryland because the summers are too hot and the winters do not provide sufficient cold to satisfy the tree’s dormancy needs. We have the ideal climate to grow crape myrtle, a tree (or shrub) that adds so much to any landscape.

Hoe them out and bury them — or eat them

Winter weeds have loved mild winter we’ve been having. Annual bluegrass, cardamine, chickweed, henbit and mares-tale, to name a few, are twice the size they were this time last year. Unless you eradicate them now, they are likely to cover the ground by the time you’re ready for planting. They may already be flowering and producing an abundance of seeds.

High in calcium and potassium, it keeps lawn and garden soil balanced

Wood ash belongs in the garden or on the lawn, not in the trash can or in the compost bin. Wood ash is basic in nature and an excellent source of calcium, potassium and trace elements. This means ash can be used as a substitute for limestone. A five-gallon pail of wood ash will treat approximately 100 square feet of a garden or lawn with a pH of around 6.0.

Attack overgrown plants before this year’s growth starts

If you have overgrown plants that are smothering the house or taking over the landscape, now is the time to strike. Hollies, yews, viburnums, forsythia, azaleas, rhododendrons and many more take well to hard pruning. Butterfly bush should be pruned very hard, to within inches of the ground, every year.     The only plants you can’t prune severely are conifers such as junipers, cedar, pine, spruce and fir. These species do not form adventitious buds, nor do they have latent buds capable of sprouting after all other buds have been removed.

Now’s the time to get it right

Step 1 to a productive garden is getting the location right. Plants perform best in full sun and well-drained soil. You can improve other aspects of a garden, but there is no substitute for full sun and a soil that drains properly.     Next, prepare a soil test. Your soil may do fine for grass and weeds, but that doesn’t mean it’s good for gardening. The pH, nutrient concentration and organic matter in soils are important and can be improved.

Cleaner air may be leaving your plants hungry

Billions of dollars have been spent making the air we breathe cleaner. We may be breathing better, but soil tests indicate that gardeners and farmers will have to add sulfur (S) to the list of nutrients that need to be added as a fertilizer.

Last year, I started from seed and had my biggest and best crop ever

If you planted garlic last fall, it now needs mulching with compost. I use compost made from either crab or lobster waste. Both have a good supply of calcium and a medium to high level of slow-release nitrogen for when soil temperatures rise above freezing. Mulching also protects these shallow-rooted plants from rapid temperature changes.

Put those seed catalogs to good use

Perhaps you have received seed catalogs for the coming spring planting season. On the the front and back cover you will likely be encouraged to order early to receive bonuses or discounts. Many seed companies also offer free shipping for early orders. You can save quite a bit if you take advantage of these special offers.

Anne Arundel County offers just the right raw ingredients

Anne Arundel County has more horses than any other county in the nation. It follows that we also have more horse manure. Some of that horse manure occupies precious landfill space or is dumped near streams, thus contributing to Bay pollution.
