Plant my heliotrope
In earth or pot?
It's simple, if you do not live in a Mediterranean climate, it will be in pots! Indeed the heliotrope likes the sun and fears the cold as the fresh winds - it freezes when the thermometer drops below -4 ° - or you will have to resolve to grow the heliotrope as an annual.
Plant the heliotropes bought in bucket in the spring, after any risk of frost is past due.
In pots, plan a mixture of 1/3 coarse sand and 2/3 of potting soil or decomposed compost.
To plant in open soil:
The soil must be well drained and the relatively cool.
If your soil is poor, enrich it with decomposed compost or potting soil. If it is heavy, mix it with 1/3 of coarse sand.- the heliotrope will appreciate! Keep a distance of 30 cm between each plant.
Water my heliotrope
Water regularly but not excessively during vegetative growth and flowering.
In pots, if you bring in your seedlings for the winter, watering once a month should be enough.
Mulch my heliotrope
You can mulch between the plants - this will limit evaporation from the soil, and thus the need to water and to weed.
Prune my heliotrope
Vigilant deadheading once or twice a week will prolong the blooming period !
Shelter my heliotrope
The heliotrope is frosty - it would not survive a winter outside! If your plant is in a pot and you have a sheltered place remaining at a minimum temperature of 10 ° C, sufficiently lighted, get it back in for wintering before the first freezes.
Water very few during the winter.
Put outside my heliotrope
From early April, you can put your heliotropes out in the light.
Remove my heliotrope
If your heliotrope is in open soil and you can not imagine that it survives the winter, tear it off before you see it freeze!
In areas with a mild climate, you can try wintering it in open soil a new year by cuting it close to the ground and mulching it carefully.
You can of course choose to put it back in pots, by taking out the whole root ball (without breaking or cracking it, if possible) with a spade. It will then be necessary to put the pot in a shelter for the winter.
