During the first few weeks of fall, plant bulbs at a depth that is about four times the diameter of the bulbs. Plant smaller-growing alliums 7.5-10cm (3-4in) apart, while taller varieties require at least 20cm (8in) between the bulbs to develop successfully. To view the complete response, please click here.
How deep do you plant Allium bulbs?
Plant allium bulbs in the fall at a depth that is at least four times the size of the bulb (at least 15cm deep). If you plant them too deeply, they will grow more quickly than if you put them too shallowly. You don’t have to water them in if the soil is moist enough to do so. Poor soils should be fertilized in the spring, when the first signs of growth emerge on the plants.
When should I plant alliums?
Autumn is the best time to grow alliums, according to experts. Planting allium bulbs in the garden should be done in the autumn months. Dig a hole for each bulb, or if you are planting a large number of bulbs at the same time, dig a trench. I like to plant in good drifts rather than in groups of twos and threes in order to avoid a dotty appearance.
How do you grow alliums in Arizona?
Alliums thrive in wet, well-drained soil that receives plenty of sunlight. Growing them amid low-growing herbaceous plants, which will help to conceal their ugly strappy leaves after flowering, is an excellent strategy.
Can I leave Allium bulbs in the garden?
Planting allium bulbs in the garden year after year is recommended. Make a mental note of where you’ve put bulbs so that you don’t accidentally harm them while you’re planting fresh plants. Allium bulbs will begin to proliferate after a few years. In certain situations, you’ll observe that the white bulbs are being pushed out of the ground by the roots.
