A quick growing green manure crop or as a sanctuary for predator insects to feed and plan their assaults from. Provides nectar with carbohydrates for energy and protein- filled pollen for egg production, assisting biological control efforts.
Phacelia has a deep root system and is a good phosphate scavenger, absorbing phosphate from deep down the soil profile and making it available for following crops.
Uses in Beekeeping - Tansy is an organic wax moth control. The aroma of Tansy leaves deters wax moth. In the autumn when you are packing away your honey supers, stack with a good spread of Tansy leaves between each box. Then if you are able, wrap the whole lot with pallet stretch wrap. Minimise any places the wax moth can enter, and the Tansy should do the rest.
I have also heard that Tansy planted under an apple tree helps deter Coddling Moth, so why not plant your Tansy there and get two benefits from this plant. Tansy grows to 90cm and has highly aromatic fern like leaves. Perennial, Sow into pots in spring. Full sun. One packet will grow plenty of Tansy for a hobbyist beekeeper.
