Gardening To-Dos for March 2020

March in Your Garden:

Work in the Garden

Petunia Get your spring garden ready for planting by cleaning all beds of debris and old, dead plants.  Lightly cut ground covers.  This is the most important month to fertilize.  We recommend an organic granular fertilizer such as Gro-Power and a water-soluble spray such as Grow More Super Bloomer. Check irrigation systems and make necessary repairs before spring growth begins.

Bedding Plants

Start planting annuals such as Alyssum, Marigold, Petunia, Gazania, Dianthus and Lobelia for the summer garden. For those shadier areas, use Begonias, Impatiens and Primroses.

Vegetables & Herbs

Plant vegetables such as tomato, pepper, chives, onions, and lettuce. Plant herbs such as basil, parsley, dill, cilantro, and mints.

Apple Pink Lady Fruiting Plants

Plant fruit trees. This is the best month for selection of stone fruit. Browse our current flipbook to view a selection of our 2020 fruit tree varieties. Choose from apple, peach, nectarine, plum, pear, apricots, and pomegranate. Citrus and avocado are just about ready for planting as well. Oranges, lemons, tangerines, kumquat, limes, grapefruit, and avocado are all available. Be sure to ask about planting do’s and don’ts for fruit trees.       

Lawns

This is the best month to begin work on your lawn. Rake, fertilize and reseed bare spots. Fertilize with a 3-1-2 fertilizer, then switch to high nitrogen foods once a month until summer. Fertilize when the grass blades are dry, and the soil is moist. Immediately after application water thoroughly. See our page on sod (insert link) for variety info.

Roses

It is almost the peak time to buy container roses as they will be in full bloom and you can see exactly what you are buying. Check out our Rose List and start doing some research now into which varieties you’ll want to add to your beds. Remove buds on existing plants to encourage more blooms. Remove dead and diseased sections.  Continue spraying with a fungicide.  Mid-month begin using treatment as needed for mites.  Remove weak, inward growth and suckers that won’t bloom. Pinch off side-buds of hybrid tea roses for larger blossoms. Fertilize every six weeks.

Ficus Fiddle Leaf Fig Houseplants

Repot older plants with fresh potting soil such as Edna’s Best. Take advantage of Evergreen Nursery’s great house plant pricing to replace or add new indoor or outdoor plants. We’ll be receiving our 2020 order in mid-March. Dust or wipe off leaves on indoor plants to help prevent spider mites.

Pest Control

Inspect for aphids and spider mites and spray is necessary to keep them under control. Gophers are breeding now so it is important that you trap, flood or bait them. If you have a weed problem, your best bet it to pull them regularly before roots take hold, then spray with a pre-emergent herbicide to prevent new seeds from germinating.  Apply broad-leaf weed controls to keep crabgrass from lawns. Bait for snails and slugs around new plantings.

Before New Plants Take Off...

Spring is the time for everything from major landscaping projects to minor gardening fix-ups. For a healthier, more productive garden, this is the most important month for fertilizing.
