As gardeners, we’re taught to nurture and protect our plants. Every seed, every stem feels like a living piece of potential, one that we can help grow into something beautiful and useful. But sometimes, plants simply outgrow their usefulness, fail to thrive, or even become harmful to our gardens. It’s okay to let them go—and yes, sometimes that means throwing them away. Here’s why, and how to make peace with this part of gardening.

1. Plants Can Outlive Their Purpose

Perennials that were once thriving can become weak, overgrown, or prone to diseases. When plants begin declining, they stop being beneficial to the garden, and they may even hinder the growth of other plants by competing for water and nutrients. Letting them go opens up space for new, healthier additions.

2. Dish Gardens Don’t Belong in the Landscape

Indoor plants in dish gardens are often created from tropical species or succulents that thrive in controlled indoor conditions but not outdoors. Releasing these plants into the landscape not only leads to a poor outcome for the plants themselves but may also disturb local ecosystems.  Many of the plants found in dish gardens are considered invasive species and can overtake native plants. Instead of trying to plant dish gardens outside, consider repurposing them, composting them if appropriate, or simply discarding them.

3. Holiday Plants Often Aren’t Suited for Outdoor Life

Holiday favorites like poinsettias, Christmas cacti, and Easter lilies are usually grown for temporary indoor display. Once their seasonal beauty fades, they often don’t do well outdoors in most landscapes due to climate and care requirements. Poinsettias, for instance, need very specific light conditions to bloom again and may struggle in non-tropical areas. Rather than planting these in the landscape, it’s okay to discard them after the holiday season—doing so can even prevent the spread of unwanted pests and diseases.

4. Diseased Plants Can Harm Your Garden

Once a plant is sick with a severe disease or pest infestation, it can easily spread to nearby plants. Tossing it—properly disposed of in a sealed bag if the disease is serious—will protect the rest of your garden. Think of it as a preventative measure for the health of your other plants.

5. Unwanted Growth and Weeds

Weeds, self-seeding plants, or plants that have taken over more space than intended can all throw off your garden’s balance. Aggressive growers, like mint or certain grasses, might look pretty, but they can overrun a garden quickly. Pulling these out and discarding them is sometimes the best way to keep your garden design and ecosystem in check.

 6. Recycling and Disposal Tips

• Compost: If the plant is healthy and not diseased, composting is a great way to recycle nutrients back into your garden.
• Yard Waste Services: For larger plants or those with disease, check your local yard waste program for pick-up options.
• Mulching or Trimming: Sometimes, you can simply prune or trim a plant rather than uproot it. These trimmings can be used as mulch if they’re disease-free.

Remember, Letting Go is Healthy for Your Garden (and You)

Gardening is about growth, not guilt. Every plant removal is an opportunity to create a new space for something beautiful to take root. It’s okay to throw plants away, knowing that each choice you make keeps your garden thriving.
