How to plant roses
You can plant pot roses, if well rooted, almost all year round, except in periods of intense heat or cold, while bare-root plants should be planted only during periods of vegetative rest, from November to February-March depending on latitude.
Avoid the times when the ground is frozen, too wet or covered with snow.
HOW TO PLANT POT ROSES
For pot roses, dig a hole slightly larger than the size of the container and mix the soil that you removed with the universal soil; place the rose in the hole without loosening the root ball or damaging the roots, adding a little soft earth at the bottom.
Make sure that the graft point is at ground level. When the planting is completed, press down lightly so that no gaps remain between the walls of the hole and the root ball. Water thoroughly.
HOW TO PLANT BARE ROOTS ROSES
If the rose is bare-root, dig a large hole about 40 cm x 40 cm, depending on the size of the plant and the length of the roots. You can shorten slightly thinner roots if they appear too long, threadlike or damaged.
The largest roots should already have been cleaned and cut to the right size by the producer, but you can cut off a bit more if they are damaged or mouldy.
The branches can be reduced up to 15-20 cm. Now mix the soil that you removed when digging the hole with universal soil. Form a small mound at the bottom of the hole on which to place the plant so that its roots lie flat and spread out.
Fill the hole with the rest of the soil mixed with universal soil. Compress lightly with the foot so that the roots are always in contact with the soil.
Before finishing water thoroughly, then add the same soil or garden soil, until more than half the rose is covered, this allows you to avoid dehydration and excessive transpiration during periods of frost and the wind.
The bearded irises are easy to grow and, given their great adaptability, require very little care and can be planted in many different places and types of soil. Simply ensure that they are not planted in too shady a position or too close to the base of shrubs.
In poorly drained soils, you can raise the part to be planted by 20-30cm.
Usually irises do not require fertilizers in soil that has been little used and where irises have not been planted before. In other cases they only need to be fertilized twice with a low nitrogen mix – the first time during the summer rest (July-August), the second (optional) a good month before flowering.
However, fertilization is required where irises have been cultivated for more than a couple of years, to allow the plant to develop and flourish in a satisfactory manner.
In clay soils the plants can get through the summer without water, otherwise you should not water the plants too much. Take care that the plants do not have to compete with weeds or are planted too deep.
The rhizome should be planted so that half its height is covered by earth, the rest being proud of the surface. Dig a small hole of about 20 cm deep and place the rhizome on a sort of mound of earth, spreading out the roots.
Then fill in the hole and firm in so that no air spaces remain and the plant is given a solid anchorage. Water with moderation.
