Choy sum succession planting schedule for year round Asian green harvests in raised beds

To achieve year-round harvests of choy sum in raised beds, a consistent succession planting strategy is crucial. This involves planting small batches every 2-3 weeks to ensure a continuous supply. The key is to adapt planting times to your local climate, considering temperature and sunlight.

Spring Planting (March - May):

Begin as soon as the soil can be worked, typically after the last frost.

* March: Plant the first batch. Choose a location in the raised bed that receives full sun. Prepare the soil by incorporating compost and ensuring good drainage. Sow seeds about 1/2 inch deep and 1 inch apart. You can sow densely and thin later.

* Late March/Early April: Plant the second batch.

* Mid-April: Plant the third batch.

* May: Continue planting every 2-3 weeks. As temperatures rise, consider planting in a spot that gets some afternoon shade to prevent bolting.

Summer Planting (June - August):

Summer can be challenging due to heat, which can cause choy sum to bolt (flower prematurely) and become bitter.

* June: Plant the first summer batch. Select a raised bed location that offers significant afternoon shade. Water consistently and deeply to keep the soil cool and moist. Consider using shade cloth over the raised bed if natural shade is insufficient.

* Late June/Early July: Plant the second batch.

* July: Plant the third batch. Continue to prioritize shade and consistent watering.

* August: Plant the final summer batches. Aim for early August plantings for a late summer/early autumn harvest.

Fall Planting (September - November):

This is an ideal time for choy sum as cooler temperatures promote slower growth and sweeter flavor.

* September: Plant the first fall batch. Full sun is generally beneficial again. The soil will still retain some warmth from summer.

* Late September/Early October: Plant the second batch.

* October: Plant the third batch. Choy sum can tolerate light frosts, and some growers find that a light frost actually improves the flavor.

* November: Plant the final batches for a late fall or early winter harvest. In milder climates, these plantings might overwinter.

Winter Planting (December - February):

This is only feasible in regions with mild winters where temperatures rarely drop below freezing for extended periods.

* December: Plant a small batch in a sheltered raised bed, perhaps one that receives maximum sun exposure. Consider using row covers or a cold frame to offer protection from frost and harsh winds.

* January: Plant another small batch, again with protection.

* February: Begin planting for early spring, mirroring the late winter strategy.

By adhering to this staggered planting schedule and adapting it to your specific microclimate and the season's conditions, you can enjoy fresh choy sum from your raised beds throughout the year.
