Sowing & planting

Plant my spanish dagger
This yucca resists up to -15 ° C, so you can plant it in the open soil, in a well-drained soil in full sun, sheltered from dry winds.
Desert plant, loving hot and dry environments, the Yucca fits pretty well inside our homes and apartments. It will grow well at a temperature of 18-22 ° and needs light.
Be careful however: avoid placing it directly behind a window to the south, the direct exposure could overdry it. Therefore prefer the proximity of a window facing west.
Water my spanish dagger
Yucca doesn't like moisture, but it still has it's own need of water. As soon as the soil is dry to a depth of one or two centimeters, water your yucca, ensuring you moisten all of the topsoil.
During growth seasons (spring, summer), watering should be regular, about once or twice a week, but controlled, to make sure the roots don't drown. In autumn, gradually reduce watering until winter, when once-monthly watering will suffice.
Take care of my spanish dagger
In dry weather, spray your plant with water not too hard, clean the dust on the leaves: it will be all the more beautiful and you will protect it from red spiders - its main enemy!
Prune my spanish dagger
Let the yellowened lower leaves dry by themselves before tearing them of: they are quite normal in the cycle of life of the yucca, which renews its foliage.
Light pruning can also be done in the spring, from February to May, by removing leafy branches starting from the trunks.
Keep 3 to 5 leaves on each branch, otherwise it will have difficulty to grow back.
If a branch has become too big and you do not want it to grow back, then cut it at its base, one centimeter above the fork.
Fertilize my spanish dagger
In summer, add liquid fertilizer for green plants every 2 weeks. We recommend a good quality liquid compost "tea", diluted to 1/10th strength. If you like chemistry, a slow release fertilizer is possible... Stop all fertilizer treatments at the end of summer.
Repot my spanish dagger
Every 3 or 4 years, at the end of winter, transplant your yucca carefully to a slightly larger pot than it's current, adding a mixture of sand, topsoil and garden soil.
Check on my spanish dagger
Keep a close eye on the leaves: if they are deformed it is either a lack of light or an excess of water. Try both: find a brighter location and reduce watering.
Put outside my spanish dagger
Do not hesitate to take out your yucca for the summer!
Just avoid placing it directly in direct sunlight - acclimate it gently, and of course, increase the watering!
You should bring it inside at the end of the summer.
Shelter my spanish dagger
Your yucca is quite hardy - but if it is in pot you can bring it inside !
