Autumn is one of the most beautiful seasons for gardeners. Temperatures drop, the first rains arrive… and it’s the perfect time to plant bulbs! Whether you’re thinking of tulips, daffodils, hyacinths or freesias, or edible bulbs like garlic and onions, October and November are ideal months to get your hands in the soil.
In this guide, we’ll walk you through how to plant bulbs step by step, with practical tips tailored to Malta’s mild Mediterranean climate, where winters are short and rarely frosty.
1. Choose the right spot
The first step is choosing where to plant. Flowering bulbs love light: they thrive in full sun or partial shade. Whether you have a garden bed, a balcony, or just a few large pots, you’re good to go.
One thing to avoid? Standing water. Bulbs hate soggy soil, so make sure the area has good drainage. If the soil is too compact or clay-heavy, mix in some sand or compost to loosen it up.
2. Prepare the soil
Good preparation makes all the difference. Loosen the soil to at least 20 cm deep. Remove stones, weeds, and any old roots.
You can enrich the soil with a bit of well-rotted compost or manure. Bulbs are like little batteries — they need a nutrient-rich base to fuel their growth.
3. How deep should you plant bulbs?
Here’s a golden rule:
Plant your bulb at a depth that’s 2–3 times its height.
So if the bulb is 5 cm tall, plant it 10–15 cm deep.
A few helpful examples:
- Tulips & daffodils: 10–15 cm deep
- Hyacinths: about 10 cm
- Freesias, anemones, ranunculus: 5–8 cm
- Garlic & onions: 3–5 cm
Spacing also matters: generally 10–15 cm apart is enough, though you can plant them closer if you want a fuller look.
Most importantly:
Pointy end faces up
Flat base (where roots grow) faces down
4. Water after planting (but don’t overdo it)
Once your bulbs are in the ground, give them a good watering to settle the soil around them.
After that, there’s no need to water often — Malta’s autumn rain usually does the job. Just keep an eye on them if the weather is unusually dry.
5. Mulching is a smart move
To give your bulbs extra protection from cold (even though frost is rare in Malta), cover the area with a thin layer of mulch: dry leaves, bark, straw, or even cut grass.
This helps to:
- Maintain moisture
- Suppress weeds
- Encourage healthy blooms
6. Be patient and let nature work
Once planted, bulbs begin to grow roots quietly underground. You may not see anything for a while — that’s normal.
The first shoots will appear between late winter and spring, which will be followed by flowers. After they bloom, there’s one very important rule:
Don’t cut the leaves right away!
Let them turn yellow naturally — that’s how the bulb stores energy for the next season.
Planting in pots? No problem!
You can follow the same steps in containers. Just make sure your pot:
- Is at least 20–25 cm deep
- Has proper drainage holes
- Is filled with a mix of potting soil + sand + compost
For a decorative look, try layering bulbs (larger ones deeper, smaller ones on top), or mix different types for a longer bloom period.
Why Some Bulbs Need to Go in the Fridge Before Planting
In mild-winter climates like Malta, certain spring-flowering bulbs — especially tulips, hyacinths, and crocuses — may not get enough natural cold to trigger proper blooming. These bulbs normally rely on several weeks of cold temperatures (usually below 10°C) to activate their internal clock and begin the flowering cycle. This process is called vernalization. If the winter is too warm (as it often is in Mediterranean regions), the bulbs might grow leaves but fail to flower, or bloom weakly.
To solve this, you can pre-chill the bulbs in the fridge before planting:
- Place the bulbs in a paper bag (never plastic!) and store them in your fridge for 4 to 6 weeks at around 4–8°C.
- Keep them away from fruit, especially apples and bananas, as the ethylene gas they release can damage the bulbs.
- After this cold treatment, the bulbs are ready to be planted and should bloom beautifully in late winter or spring.
Final thoughts
Planting bulbs in autumn is easy, inexpensive, and incredibly rewarding. With just a bit of planning and care, you’ll enjoy beautiful blooms from February onwards. Whether you have a big garden or just a few balcony pots, it’s always worth a try!
