Description of Alta flower
Althea, or Tree Mallow, produces a lot of ramifications, so a lot of branches that produce flowers. Althea can be grown in a tree, this work is rather limited to seasoned home gardeners, but if you like it in this form, you will find it in this form in the garden center. The tree can then be pruned into a ball, for example.
Method of multiplication of altéa
• Sowing is possible but the simplest method remains the practice of cuttings.
How to sow the altéa?
The seedlings of the altéa are more complex for 2 reasons, first you have to find the seeds, then the seeds before being sown should be stratified. Stratification is a natural operation which aims to restore the seed to its fertile capacity. In general, the seeds that are to be stratified have an envelope, stratification destroys the envelope. The seed in contact with the earth can then begin its germination process.
Collect the seeds:
The Altéa or Tree Mallow produces small fruits which when opened, release the seeds. The ideal is to place a small bag with a rubber band around several fruits in order to collect enough seeds before they fall to the ground.
Stratify the seeds, 3-step stratification:
Start layering at the very beginning of the year.
• Soak the seeds in twice their volume of cold water 5 ° C MAX for 2 days.
• Then, in a waterproof and transparent “tupperware” type box, place them in successive layers in damp sand, a bed of sand, seeds and so on. close the waterproof cover.
• Place the box at an average temperature of 20 to 25 ° C.
• Open the lid weekly, for 6 to 8 Weeks.
Laminate the alta seeds, outdoors:
• From autumn, in a terracotta pot, place the seeds in successive layers in a soil-sand mixture.
• Place the pot outside in the shelter of a wall. The pot will have to receive the rain which will make it possible to moisten the earth but no more.
• The seeds will spend fall and winter under natural conditions and degrade.
• The following spring they should be able to germinate while sowing.
• Prepare buckets filled with seed soil.
• Place one seed per bucket pushed in at 3 times its size.
• Keep moist until rising.
• Then water on dry soil.
• Wait until autumn to replant in the ground.
When to cut the altea?
• In spring, in April or May.
How to cut:
• Select a young spring shoot, on a supporting branch, of about 20 cm. It should not bear any sign of disease or parasite.
• Cut it in a "T", keeping the whole small branch as well as a small section 4 cm from the supporting branch.
• Remove the leaves from the cut on half of the branch.
• Prepare a bucket half full of soil for planting.
• Place the cutting.
• Fill with potting soil, tamping down well.
• Water well.
• Place everything under the frame if you have one ...
• Otherwise use a clean freezer type bag.
• Use it as a bell that covers the plant.
• Close tightly with a rubber band on the pot.
• Open once a week to check that the soil is still moist and to allow the plant to breathe fresh air.
• You can transplant in the fall or the following spring.
A word from the gardener:
• For more success, Find some hormone powder for cuttings and sprinkle it on the cut ends of the branch before placing it in the ground in the cup.
• What is this type of cutting called ? A “crossette” cutting due to the “T” butt.
• Before making the cutting, clean /disinfect all the tools, pruning shears, scissors ...
When to plant an altea?
• For planting in the ground, from the end of October to April.
• For an already large shrub, it is quite possible to plant in the spring.
How to plant the altea?
• Dig a hole 40 to 50 cm deep and in diameter.
• Loosen the soil well. Remove stones and weed roots ...
• Add a horn-based fertilizer about 100 g to the bottom of the hole, ie a nice handful, which must be mixed with the soil.
• Fill the hole halfway with a mixture of soil, planting soil and composted manure (Fumelite) or compost from the garden.
• Trim the ends of the roots of the shrub to cool them and stimulate new growth.
• Position the althea graft point at ground level or slightly buried in cold climates.
• Fill the hole with soil and possibly additional planting compost.
• Press down firmly on the foot to compact the shrub at its base, forming a bowl.
A word from the amateur gardener:
Important: watering must be abundant, a good ten liters of water. This is what will ensure good cohesion between the roots and the soil, and which will allow a better recovery.
• For plants that are already a bit large, prune Altera twigs (20 to 30cm) above a bud placed towards the outside of the antler.
