Step-by-Step Guide

Step 1: Plant when temperatures do not exceed 68° F (20° C) daily.
You can plant alstroemeria bulbs in the spring, early summer, or fall, depending on your climate.
Alstroemeria grows best when temperatures do not exceed 68° F (20° C) daily and range from 40 and 50° F (4 to 10° C) at night.If you plant alstroemeria indoors, you can do so any time of the year as long as you place the plant in a temperate location. -
Step 2: Choose soil with good drainage.
Alstroemeria plants need soil with good drainage so the roots don’t rot.
You may want to mix your soil with peat moss, compost, ground bark, or decomposed manure to help it drain.Alternatively, you could use a mix of 1:1 perlite and vermiculite or 1:1 organic and inorganic material if you plan to grow your alstroemeria in a container., Alstroemeria grows best in locations with full morning sun and some shade in the afternoons.If you’re growing alstroemeria indoors, pick a sunny window ledge or a spot with lightly filtered sunshine., Fill a bucket with water, and then place the alstroemeria bulbs into the water overnight.
Soaking the bulbs for 24 hours will jump-start their germination process., Dig 6-8 inch (15-20 cm) holes in the potting medium.If you’re planting outdoors, space the holes 24 inches (60 cm) apart to allow room for spreading.
If you’re planting in containers, plant each bulb in a large container (1 gallon or 5 liters) with drainage holes., Place 1 bulb into each hole, with the pointy side facing up.
Cover the bulb gently with soil or potting medium.
Lightly tamp down the soil or potting medium around the bulb., Generously water your freshly planted bulbs.
Monitor their moisture level daily until the plant pokes through the surface, keeping the soil consistently moist, but not sopping wet., Once your alstroemeria is established, it won’t need as much water.
Lightly water when the top 1 inch (2.5 cm) of soil is dry.
Too much water will lead to root rot, so take care not to overwater your alstroemeria., You can feed alstroemeria with a high potash fertilizer each week during the growing season when your flowers are blooming.
Potash fertilizer contains potassium to help your plants thrive.
You should be able to find this type of fertilizer at your local garden shop or hardware store., Placing protective mulch around your alstroemeria can protect it from extreme temperatures.
You can mulch with straw or bracken.
Keep the mulch at least 2 inches (5 cm) from the alstroemeria stem to avoid rotting at the base of the plant.If you live in an extremely hot climate, you may want to place mulch around your alstroemeria in the summer.
If you live in a cold climate, you should place mulch around your alstroemeria in the winter. , Whether you want to bring some alstroemerias inside to put in a vase, or you need to remove spent blooms, you’ll need to pick out each stem.
Pull one or more entire stalks out of the soil or potting medium.
Don’t cut the flowers, as the underground meristems will respond to the damage and die.Each flower has it’s own stalk, so you won’t harm the entire plant by pulling a few stalks. , Look out for aphids, spider mites, and whiteflies on your alstroemerias.
If you find these pests, remove them with a strong stream of water then apply an insecticidal soap.To avoid a disease called root rot, be sure to water only until moist, choose a well-draining soil, and leave room between your plants for air to reach your alstroemerias. -
