Plant my giant hyssops

Plant between October and the end of March but not during frost periods. Check that the desired location meets the requirements described in the description, and avoid working in soggy soil. Dig a hole two to three times as wide as the root ball of your tree. Handle the root ball carefully to keep it intact while you place it in the hole. Put your shrub to the correct height, and replace the soil, respecting the order of the layers of possible - bottom layer to top. Tamp regularly. After planting, pour two watering cans at the bottom, then place a good layer of mulch.

Water my giant hyssops

Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
