Announcements as of April 8, 2020



All Morris County parks, including the Frelinghuysen, Willowwood and Bamboo Brook Arboreta, are closed to the public until further notice. See the current announcement on the Morris County Parks Commission's website.

We will keep you posted as later news becomes available.


The Covid-19 epidemic has caused serious disruptions to all the students and faculty at County College of Morris, so we have decided to postpone awarding a Blackburn Scholarship until next year. Best wishes to all of you and stay healthy.


April is here and spring has sprung! The Magnolias are blooming as are the Forsythia, Cherry trees, Daffodils, Hyacinths and many other spring bloomers.

Tasks to address in April are many, among them:

  • Continuing to clean up the garden by picking up fallen branches, leaves and other debris. Get rid of old growth on herbaceous perennials and deciduous shrubs. This is also a great time to do some weeding, preferably early in the morning when dew is still on the ground or after it rains. As long as the soil is not too wet, you can begin digging and preparing your garden for planting, as well.
  • Make sure you have a nice, clean edge between your lawn and your flower beds. This makes for a much neater appearance and also keeps the lawn from creeping into your beds. It's easy to create a clean edge with a special edging tool or even with a flat-edged shovel. If you're creating a new bed, you can lay a garden hose along the ground to create a line where you want the new bed edge to be and then follow along with the edging tool.
  • After cleaning and edging, it's time to feed the soil with compost or well rotted manure. This will nourish the soil and enrich it with minerals and other elements necessary for good plant growth. In the absence of compost or manure, you can apply a slow-release fertilizer, making sure to stay away from synthetic fertilizers.
  • You may want to look into setting up a compost area. It's fairly simple to do, either by purchasing a compost bin or making your own, lots of tutorials online. Use a combination of grass clippings, paper, vegetable peels and leaves. Turn the mixture a couple of times a month with a rake to keep it aerated. Your garden will benefit greatly!
  • Check the garden for pests such as slugs and aphids and get rid of them with an organic remedy. Ladybugs love aphids and are a great garden ally!
  • Give your garden a running start by planting masses of colorful annuals; they will bloom while your perennials are maturing and setting buds. You can start annuals inside and plant outside at the appropriate time, or you can purchase flats of annuals at your local garden center. The nice thing about annuals is that they bloom pretty much continuously all season long. That's their job, to complete their life cycle in one season, germinate, look pretty, produce seeds and die. Also consider planting a few containers for additional color, structure and texture and place them on your patio, deck or even in an empty spot in one of your beds.

In the words of Thomas Jefferson, "No occupation is so delightful to me as the culture of the earth, and no culture comparable to that of the garden". Enjoy!
