Companion Planting: Alfalfa.

Alfalfa Medicago sativa:

Notably one of the most powerful nitrogen-fixing and maintenance free plants there is. The roots of the alfalfa plant have been known to go down into the soil as far as 50 feet bringing up many minerals and nutrients to the surface of the soil. The average depth for alfalfa roots is 20-30 feet.
The great thing about alfalfa is that once it gets established, you will never have to do anything with it because it’s basically maintenance-free, and also that you can usually get 3 or more cuttings per season from one alfalfa plant. Like legumes, alfalfa also has the ability to fix nitrogen in the soil where other plants can utilize it, so cut it back 3-4 times per season and put the tops in the compost pile or till them into the garden and especially the greenhouse which always needs to have the nitrogen in the soil replenished. Alfalfa makes a great compost activator.

Alfalfa is very drought tolerant which is why so many farmers use it for hay. Just keep in mind those long roots make alfalfa impossible to eradicate if you want to get rid of it in the future. So be sure to plant it someplace where you want it to be forever. Alfalfa is a large, bushy plant usually becoming 3-4 feet tall and wide and so it offers shade to nearby plants and give shelter often keeping other plants alive longer during droughts.

Companion Planting with Wormwood.

Wormwood (artemsia)Companion Planting: Plants that assist each other to grow well, repel insects or even other plants when grown next to each other can be a sustainable and eco-friendly way to improve and protect your garden against unwanted inhabitants.

Wormwood Artemisia absinthium:

Absinth wormwood takes advantage of disturbed areas where there is little plant competition. Without attention, the plant will also out-compete desirable plants and grasses in pastures, fields, and native grasslands. Growing like a small bush of about 15-24 inches with feathery silver-colored leaves. It has a smell similar to sage when you crush it in your hands and many people mistake it for sage. Planted as a border, it will keep animals away, but it will also compete heavily with any plants it is near, so plant it where you want to keep out other weeds or grass. Once established, it will not need to be watered and will readily self-sow all over your yard.
