Grandiflora
This combination of hybrid tea and floribunda roses produces large vigorous plants, and flowers on long stems. Flowers on grandiflora are present both singly and in clusters. They make good cut flowers.
Miniature roses
These perfect, scaled down versions of hybrid tea and floribunda roses come in a stunning variety of colours. These miniatures will bloom continually throughout the summer and can be grown both in and outdoors.
Rose maintenance
Watering
Roses are heavy feeders that require water at all times during the growing season. A lack of moisture will slow or halt blooming and growth. It is important that the soil has good drainage and that water never collects around the roots of roses.
• Allow the soil to become dry only a little below the surface.
• Water deeply at the base of the plants but not enough to allow water to collect for any length of time.
• Mulch may be added to increase moisture retention in hot, dry weather.
Deadheading for flowering
As your rose blooms wither they should be removed from the stem. Remove head at a shoot or leaf junction to encourage further flowering.
Pruning
(see Pruning section pg. 159, for detailed instruction) Fertilizing
Roses benefit from regular fertilizing, such as 20-20-20, 15-30-15 or 20-30-20. Fertilize only until about the middle of August. Later fertilizing stimulates new growth, which could be harmed by early frost. Fertilizer does not make roses (or any flower) bloom. They bloom when they are healthy and receive enough sunlight. Some bloom for a short period, others bloom all summer.
Winter protection for tender roses
1)Prune long stems down to about twelve to eighteen inches (45 cm).
2)Water in well. 3)Mulchheavilyatbasewithdryleaves,vermiculite
or straw.
4) Cover stems with a rose cone with the top cut out.
5)Fill container with mulch, and cover the open area with cloth to allow air circulation during Chinooks.
6)Do not cover too soon in the fall. Wait until considerable frost is expected. Covering too soon stops them from getting cold and entering dormancy, which is necessary for their survival. Uncover in spring when poplar trees are leafing out. Uncovering them too soon to see if they are alive is likely to kill them during another frost. Be prepared to cover them when frost is expected.
Note: Snow is an excellent insulator and may be piled on both shrub and covered tea roses for added moisture and protection.
