Horticulture Report – May 2019


Prune spring-flowering shrubs such as forsythia that have already flowered.

Fertilize roses early this month or mid-month if you already fertilized last month. Use a 20-20-20 liquid solution when flower buds are set. Mulch around the plants to retain moisture.

Stake perennials before they reach 6 inches.

Pinch back fall-blooming perennials such as chrysanthemums, asters, and tall sedums once a week.

Direct growth of perennial vines on their supports.

Check peonies for botrytis blight or other fungal problems. If they had problems last year, spray when plants are 2-4 inches tall. I’m quoting: There are fungicides that can help protect your plants from Botrytis blight. You need to look for a product that says on the label that it can be used on the specific type of plant, peony, and the specific disease, for instance, Botrytis blight. There should be products with the active ingredient “Mancozeb” or some type of copper that are labeled for use on peony against Botrytis blight. In terms of where to apply the fungicide, read and follow all label directions! I don’t think it is necessary to dig out the peonies before treatment, but follow the directions above all. Fungicides should be applied to protect against Botrytis blight early in the season.

Horticulture Report – April 2019

Take it easy!

Be sure your garden beds are not too wet. If it’s been raining or snowing and the soil is saturated, you’ll have to postpone your gardening a bit longer.

Shrubs and trees

There is still time to plant trees and shrubs. However, by mid-month it will be a little late to transplant large trees or shrubs.

The months of March, April and May are ideal for pruning evergreens. If you have juniper, cypress or conifer that need shearing or pruning, this is a good time to do it. Remove all dead, diseased, and undesirable wood. Don’t prune back into the bare wood part of the plant.

Prune forsythia after it finishes flowering.

Broadleaf and needle leaf evergreens benefit most from lightly spreading a high nitrogen fertilizer around their bases.

Perennials, annuals and bulbs

April is the month for planting summer flowering bulbs like dahlias, gladiolas and lilies. Mix bulb fertilizer, processes manure and peat moss into the planting soil. Tuberous begonias and canna should not be set outdoors until all danger of frost has passed, so wait until next month.

Horticulture Report – March 2019

Shrubs and trees

In most areas it is still possible to do dormant spraying of fruit trees until the 15th, after that date dilute the spray by 1/2. Spraying should be done on a still day with the temperature above 40 degrees F.

Late March and early April is a good time to transplant shrubs and trees. As soon as the soil is workable, but before buds have swelled or broken open, you can move shrubs and trees.

Fertilize shrubs and trees if this wasn’t done in February. Use an acid type rhododendron fertilizer to feed evergreens, conifers, broad leaf evergreens, rhododendrons, azaleas and camellias. Use an all-purpose fertilizer to feed roses and other deciduous trees and shrubs. If you use granular type fertilizers, be sure to water it in thoroughly.

Finish pruning fruit trees this month – before the buds swell.

Perennials, annuals, and bulbs

There is often a strong temptation to start removing winter mulches from your flower beds…. WAIT!!! Pull the mulch off gradually as the plants show signs of new growth. The purpose of winter mulch is to act as a protector from sudden changes of temperature and chilling winds, so keep in mind that it is still winter. Acclimatize your plants by removing the mulch over a period of days, allowing the light and air to reach the new growth slowly. It is much better to remove the mulch a little later than to remove it to early.

Day Lily

Day Lillies planted this afternoon in my garden. Both I won at our September meeting. One is from our speaker’s garden and one from LindaLee’s garden. I’m excited to see how they bloom next summer! I’ll post again when they bloom in 2019!
