|Pile of Bindweed. Use as Mulch? Think Again!|
“Afternoon July thunderstorms have brought an onslaught of weeds in gardens and open space all along the Front Range. Soils too dry for seed germination this spring now have enough moisture to sprout weeds. Weeding practices may actually worsen the problem. Leaving pulled weeds on the soil surface is advocated by some as a way of mulching. Weeds dry out and die and the debris forms a mulch.
It is important to identify the weeds pulled for mulch. Some weeds can be pulled prior to setting seed and left in place with no danger of returning.Examples include: salsify, annual sowthistle, groundsel, and prickly lettuce.
Weeds such as bindweed, purslane, prostrate spurge and prostrate knotweed can root from a very small piece of stem or root. Gardeners should not leave these weeds on the soil for mulch, instead dispose of them in the trash.”

|Herbicide Carryover Injury|
Dr. Tony Koski, CSU Extension Turf Specialist, recently informed staff about an excellent publication from North Carolina on the topic of herbicide carryover.
North Carolina State University received reports from organic farmers and home gardeners of damage to vegetables following application of aged and composted horse and cattle manure to the soil. The symptoms exhibited on the crops are twisted, cupped, and elongated leaves; misshapen fruit; reduced yield; death of young plants; and poor seed germination. They found that one source of this crop injury is the presence of certain herbicides in manure and compost. With so many folks using composts and manures to improve soil, there have been increasing cases of contaminated amendments. Unfortunately certain herbicides can pass through the digestive tract of grazing animals and into their manure. Some straw products can contain herbicide residues used to manage weeds growing in the crop.
Read more about the problem, recommendations and how to conduct a bioassay – a test for determining if that manure you’re going to buy from a local farmer is such a good idea! Read the report here: Herbicide Carryover Injury

|Common blue violet|
Ground ivy, also known as creeping Charlie, Glechoma hederacea, offers lush dark green leaves that are rounded with toothed edges and small funnel-shaped purplish-blue flowers in the spring. This perennial belongs to the mint family and has square stems and a pungent odor when the leaves are crushed. Ground ivy and wild violets can sometimes be confused when flowers are not present.
Both plants spread via seed from blossoms, branching rhizomes, and creeping roots. With so many options to expand their range, it’s easy to see how they do so very easily. These plants will simply spread out of your landscape beds and into your lawn. Removal of them is a little more complicated. Hand-pulling often just results in a lot of time and effort and broken off plants as they have extensive root systems. Herbicides are usually recommended.

With the abnormal amounts of rain we have enjoyed we need to be alert to this condition and take steps to prevent its onset. Once a fruit has been damaged it cannot be cured!
The technical term for this condition is “Blossom End Rot” and in some areas it is just referred to as “BER”. This condition is a result of the plant’s need for calcium not being satisfied.
