Choosing The Right Time To Plant
Choosing the right time to plant walla walla onions is crucial to ensure a successful harvest. These sweet onions should be planted in the springtime when the soil temperatures are around 50-55°f and there is no danger of frost. However, if you live in a cooler climate, it is recommended to start your seeds indoors 8-10 weeks before the last frost.
This gives the seeds enough time to germinate and develop healthy roots before transplanting them outdoors. Make sure to choose a well-draining location with fertile soil and plenty of sunlight. After planting, water the onions regularly and apply a top layer of organic mulch to retain moisture and suppress weed growth.
With the right timing and care, you’ll be able to enjoy a bountiful harvest of delicious walla walla onions.
Preparing The Soil
To prepare the soil for planting walla walla onions, select an area that receives full sun, has good drainage and is weed-free. Using a garden fork or tiller, loosen the soil to a depth of 12-14 inches. Add compost or well-rotted manure to improve soil fertility and structure.
With these simple steps, you’ll create the perfect canvas for your walla walla onions to grow strong and healthy. Remember to water them regularly and keep the area free from weeds and pests. With a bit of patience, you’ll soon be enjoying the delicious taste of homegrown onions in your favorite recipes.
