Asparagus
The initial wait for asparagus is long (2-3 years until you can harvest it) but you’ll be able to get them every year for 30 years!
How to start it
The easiest and the most cost-effective way is planting bare roots in spring. Do NOT harvest until year 3 – Allow it to develop a strong root system so it doesn’t get weaken too much when you snap it off.
Requirements
In general, asparagus tolerates a huge range of temperatures. Plant it at a sunny spot with rich soil.
Water
Drip line + mulch to keep your soil moist. 1-2″ every other week in one application for the 1st-2nd year. Water every 3 weeks after year 3.
Soil
Organic, rich, well-drained, sandy soils and slightly acidic
Climate
Zone 3-8. 6-8 hrs of full sun is ideal.
Plant with…
- Strawberries, lettuce, spinach: they have different root zone and asparagus fern can create shelter on extra hot days
- Basil, dill, cilantro: attract beneficial bugs
- Nightshades (tomato, pepper…), nasturtium: repel pests
Pests
Select the right companion plants to attract beneficial bugs (ex: ladybugs or wasps) to attack pests. Or use insecticide soap.
Asparagus aphids
Green plant-sucking insects that stunt growth
Asparagus beetles
Larvae eat fern and adults feed on emerging spears in spring.
Grow and divide
After 5 years, you can divide your asparagus roots with your shovel when it’s dormant (late winter/early spring.)
