Regenerative Gardening Tips and Tricks
The Metro Denver Green Homes Tour includes presentations that are free and provide valuable and timely information to support the tour.
We recently learned about the concept of regenerative gardening, which is particularly relevant this year due to the severe drought.
Brianna Selstad Bosch operates a two-acre flower and vegetable farm in the Lakewood area, which she has transformed from untamed, wild land over the past several years. She shared with us the best practices she has acquired during this period.
Regenerative differs from the current understanding of organic gardening associated with certification programs. Prior to the certification of organic practices, the focus was on soil health. The introduction of a new term emphasizes returning to soil conservation and enrichment. Some traditional methods have been improved or substituted, hence the necessity for a new term. It centers on soil health and weed management.
Soil from the ground is preferable for enhancement compared to trucked-in or bagged soil, which may contain contaminants. This is particularly true for plastic from bags that have been stored in hot conditions.
Cover crops are the most significant amendment for the soil. They fix nitrogen and other essential minerals within the soil and adapt to the specific needs of different crops. They must be terminated before flowering, ideally at a crucial dry stage. Crimping or bending the plants is an effective method for termination. Artificial fertilizers can interfere with the natural distribution of beneficial rhizomes.
Steer clear of typical mulching techniques such as plastic or carpet, as they may cause harm. Cardboard can also choke the soil. The most effective strategy is to use native soils for planting. Allow the garden to rest. Tillage isn't an issue if it's not performed annually.
Consider planting in Colorado as a seasonal activity and align cover cropping with the seasons. Plant cover crops for cold crops from mid to late October and warm crops in March. Avoid watering over mulch. The best mulches include pine shavings, tree leaves, and pine needles. Be sure to cover mulches so they don’t blow away. Burlap is a good stakeable natural option. Pine needles are less likely to blow away. They form an interlocking mass that stays put.
The soils in Colorado are often very alkaline and can have high salt concentrations. It's best to avoid using alkaline soil amendments. Compost can also be high in salt. You might want to add alfalfa pellets, and there are specialized mixes that include molasses and other ingredients available.
Herbicide can combat harmful weeds such as bindweed. It is very challenging to eliminate. Use a paintbrush to apply it directly to the leaves. Wear a mask and gloves for protection. Apply sparingly, only as needed to manage competition with desirable plants.
