The green swards in front gardens throughout the UK are not as environmentally friendly as you may think.

While walking in the South Carolina Botanical Garden, I came across a substantial pile of Elaeagnus recently cut from our woods. My eye was caught by the silvery underside of the leaves flashing in the sun. Elaeagnus have a distinctive form: multiple stems at the base, which shade out other plants, and whip-like, elongated stems above. Battling Elaeagnus, along with English ivy, Chinese privet, and Kudzu, is ongoing in many places, including the SCBG. These plants were all introduced with good intent in the 1800s but rapidly got out of control and became invasive.
Elaeagnus colonizes an area rapidly, spreading by both suckers and seeds. One plant can have up to 20,000 tasty single-seeded drupes scattered far and wide once eaten by birds and mammals. In addition, this plant fixes nitrogen enabling it to colonize even the poorest soils. Once established, Elaeagnus shades out other plants to create a dense monoculture. The lack of plant diversity negatively affects animals who rely on native plants for survival.
The negative environmental impact of Elaeagnus landed it on the South Carolina Exotic Pest Plant Council’s Invasive Species List, and on October 1, 2024, its sale will be banned. You can be a good environmental steward by taking pre-emptive action to remove Elaeagnus from your landscape. Small plants can be hand-pulled. Larger shrubs or trees should be cut, and either an herbicide can be applied or continued cutting will be necessary to stop new sprouts from growing. Once eradicated, replace Elaeagnus with native alternatives. Some excellent native choices include wax myrtle (Morella cerifera), yaupon holly (Ilex vomitoria) or inkberry (Ilex glabra), serviceberry (Amelanchier arborea), dogwoods (Cornus drummondii, C.

Pamper your plants by all means but resist the urge to over feed.
A rose is not a rose when it is a Lenten or Christmas rose!
‘What else did the Romans do for us’ asks Monty Python. ‘All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public health, what have the Romans ever done for us? ‘ Well if you include Latin as a language they gave us modern gardening nomenclature.
The year 2020 is set to be memorable for far too many reasons. At the moment I will only stick to comments about plant and garden viruses but note we ‘caught a cold’ on the wet winter.
Yorkshire has suffered an exceptionally wet autumn culminating in disastrous floods at Fishlake and around the river Don. One plant that will thrive in these wet northerly conditions is our old friend Moss. As this has been covered before I am just using this post to link you to other observations and tips about moss.
Fall brings that time of year when leaf color can be its most vibrant! However, as time marches on towards the winter season, leaves quickly begin to fall to the ground and create a blanket of opportunity. Opportunity, you say. Yes, indeed.
A few years ago a friend, who was a native Alaskan, gave us a seed packet of alpine forget-me-nots (Myosotis alpestris) that she purchased on a visit back to her home state. We really didn’t think that a plant that flourishes in such a northerly region of the US would tolerate the heat and drought of South Carolina. However, we were pleasantly surprised!
You can help keep your family and our waterways safe by properly disposing of unwanted or expired medications. According to the United States Environmental Protection Agency (EPA), the proper disposal of medications can prevent:
In a year when many of our favorite sporting events have been postponed or even canceled, the garden marches on! As gardeners, we have our own backyard competitions each year, keeping mental notes on which varieties we will plant again or replace due to their performance on our ‘home court’. But choosing which varieties will be in our starting lineup each year can become a daunting task.
Interest in home gardening has flourished throughout the COVID-19 pandemic. In response, Clemson Extension’s Horticulture team is evaluating the best ways to meet the growing public demand for gardening knowledge.
The recent news that all Pyrus calleryana cultivars – the most common of which is the Bradford pear – and several Elaeagnus species have been added to the “do not sell” list in South Carolina has generated a lot of buzz and a lot of questions from homeowners. We’ll try to answer some of those questions in this blog post.
