Can You Compost Rhubarb Leaves Safely?

Rhubarb leaves can be composted safely as long as they remain out of reach from children and household pets. Oxalic acid present in the leaves quickly degrades during composting without having any detrimental effect on final product quality.

Add rhubarb waste in small amounts to your compost pile with other nitrogen-rich green materials and carbon-rich brown materials such as paper shreddings, sawdust or hay to optimize conditions for composting. Regular turning will ensure optimal composting conditions.

Oxalic Acid

Rhubarb thrives best in fertile, well-drained soils rich in organic matter. Heavy clay soils may benefit from adding compost or well-rotted manure into their planting beds for improved results.

Rhubarb grown under optimal conditions rarely suffers from serious diseases, although minor pests or fungal conditions such as Phytophthora crown or root rot may occur in some regions. Such issues tend to be easier to control than serious bacterial infections.

One common concern regarding rhubarb leaves is their concentration of oxalic acid, which can be both corrosive and toxic to kidneys. Luckily, this naturally occurring compound is broken down quickly by microbes in soil, meaning they can safely add them to compost piles as the microbes will quickly decompose any potentially toxic compounds before having an effect on other organisms in the pile – meaning any harmful compounds won’t affect other organisms, and any harmful acids won’t transfer into its final nutrient-rich results!

Composting

Rhubarb leaves make an excellent addition to compost piles, thanks to their rich source of oxalic acid that easily decomposes in hot environments such as compost bins.

When composting rhubarb leaves, be sure to wear gloves and cut the blades into smaller pieces to maximize surface area available to microorganisms in your hot compost, thus speeding up decomposition processes. This increases surface area available to them and expedites their breakdown.

Once they’re in the pile, cover them with layers of browns (dry grass clippings and leaves) and greens (food scraps). Continue turning it to speed up the process.

Rhubarb thrives in well-draining, rich soil. To give the plant time to establish itself fully and create strong crowns with healthy stalks during this stage of its growth. At times during this stage stalks may appear slender.

Pests

Rhubarb leaves and stalks contain high concentrations of nitrogen, making them an essential ingredient in home compost piles and bins as long as they have been properly prepared and included with carbon-rich brown materials for speedier decomposition. Cutting up rhubarb waste into smaller pieces speeds up this process of degradation.

Composting breaks down and dilutes oxalic acid present in rhubarb leaves to neutralize any harmful effects to microorganisms in a home compost pile or bin.

However, when composting with vermicomposting systems it’s wise to avoid adding rhubarb waste as its toxic oxalic acid content could damage worms.

If you decide to add rhubarb to your compost pile, it is vital that children and pets remain out of its vicinity. Oxalic acid in its leaves can be poisonous for both animals and humans alike; using physical deterrents such as fencing or locking compost bins to minimize accidental ingestion will help minimise risks of accidental consumption.

Odors

While rhubarb roots can be enjoyed, its leaves should never be consumed due to their toxic presence of oxalic acid – an extremely corrosive poison which may lead to kidney failure and even numbness in extreme cases. Luckily, composting breaks down this acid into harmless substances making rhubarb leaves suitable for gardens and compost piles alike.

Make sure that the compost pile is out of reach of house pets and children who may be tempted to reach in for tasty treats from it. Furthermore, wear gloves during composting to protect yourself against exposure to oxalic acid which is dangerous both to humans and other mammals.

Rhubarb thrives in well-drained, organic soil. To sustain vigorous growth and ensure plentiful harvests, regular fertilizer applications of two pounds of nitrogen (N) per 1000 square feet in early spring is recommended; in dry conditions provide deep watering every seven to ten days as necessary to keep soil moisture levels up to par.
