Corms are bulbous small plants that form blue or purplish stalks. They have long pointed leaves and are eaten by bees and other insects. Though they can grow in a variety of soil types, oxalis should not be grown in well-drained soil or spent soil. Too much nutrients and/or too much water could cause the bulb to burst into a perfect storm of another plant and/or bug attack.
To help take these attacks out of the equation, here are some tips on how to plant an oxalis, specifically of the do-it-yourself (DIY) kind:
Seek out specific type of growing medium
For many species of oxalis, it’s recommended to select a mix of peat moss, compost, and peat moss with some balanced fertilizer. A mix of well-aerated organic soil with mixed compost and/or horticultural grit is ideal. Oxalis such as colourado forget the past and just do what it needs. This means giving them the appropriate amount of light and temperature while growing and watering. Feeding oxalis with balanced fertilizer while they’re young will ensure that, over time, they continue to bloom and produce useful foliage.
While we all wish they lived better than they do, the majority of oxalis contain pesticides, including chlorpyrifos, a chemical that’s been banned under European Union law for use on people. The human gut lining is very sensitive to chlorpyrifos and other derivatives, meaning human consumption of oxalis can very significantly impact the body. This means consumers will either have to continue to use organic or conventional fertilizers and pesticides to grow their oxalis.
Stop using… and start using… organic fertilizers
Oxalis are hearty flowers. If a slightly damp area is made available, a tiny drip of water will even prompt the plant to send up short shoots. Also keep in mind that oxalis can be visibly stunted if too much fertilizer is applied too fast.
If you are new to the growing of oxalis, try a simple book and start slowly at first. Avoid early growth because as the plant matures, it will be harder to take care of. Slow, steady growth, especially of first spring crop, is the only way to achieve quality flowers, with organically grown flowers, for that matter.
Create a safe environment
Oxalis need a minimum of 3 feet of depth in the garden and 6 or more feet indoors. The soil should not be disturbed and protected from temperature fluctuations.
Try to not disturb the leaf litter, and never smother small plants in the garden or house. This will encourage unwanted additions to the soil in the long run. Oxalis like to be free from any animal or insect influence. For best results, place these bulbs in rows and arrange them in the ground using a shovel or hoe. Oxalis need great care and full sun. Don’t forget to put the sprinkler in storage as well.
Use a good seed packet
Young plants will ripen fast with little water if they are left alone. Oxalis need good drainage and water at a rate that is equal to or higher than the growth rate. Allow the bulbs to dry out completely before transplanting.
Seek expert help
If you do encounter problems with this type of plant, ask an experienced grower what you should do. For example, when Oxalis flower buds open, they will puff up like tiny balloons from the outside. This is because of nitrate release, a naturally occurring compound in oxalis. The nitrate release can trigger the toxic mutation or a vascular disorder. In these cases, a good grower can use a pump, mix powdered nitrogen into water, and then presoak the container or garden house to ensure that this destructive release is not released as the whole plant closes. This could help keep your oxalis weed free.
Potted plants aren’t forgiving either, which means if you don’t keep them watered and fertilized, you will eventually lose all your flower buds to the dreaded fade. To add another nail to the coffin, cross-pollination with other species, such as violets, can turn your fruitless and dwarf production.
