Hybrid tea roses, unlike Old Garden Roses and Rugosas, are high-maintenance flowers. Diligent pruning, watering and mulching is required to keep these bushes in peak condition. This is especially true in areas that are known for high humidity. Residents of central Florida can take comfort in the fact that the extra attention given to their hybrid tea roses will pay off with blooms year-round and bushes that are unusually large compared to other regions of the country.
Select a variety that will grow well in your location. Consider planting varieties such as Marie Van Houtten, Mrs. B.R. Cant or Moonstone. Purchase rootstocks from the nursery from March through November to ensure that the specimens are not dormant and plan on planting your new hybrid tea roses within two to three days after purchasing.
Choose a location where your roses will receive at least six hours of sunlight per day. Try to find an area where the sunlight shines on your roses during the morning rather than in the afternoon or evening. Make sure there are no other trees or large shrubs within an 8-foot radius of the area where you will plant your new rosebush.
Till the soil in the chosen location with a garden tiller to a depth of 12 inches. Add 2 to 4 inches of peat moss or cow manure to the tilled soil. Chop any big lumps of cow manure up with a garden hoe. Till again to mix the soil and organic material together evenly.
Dig a hole six to eight inches deep and 12 inches wide with a garden spade. Place the tea rose bush into the center of the hole so the root ball is not cramped. Cover up to the top of the root ball with soil. Pack this tightly around the base of the plant.
Apply a two to three inch thick layer of pine straw or tree bark around the base of the hybrid tea rose bush. Water the plant heavily with a garden hose, taking care to soak the roots and the ground in a two foot radius of the plant. Water the bush heavily for the first six to eight weeks of growth.
Add a trellis for support. Dig a hole two to three inches deep, and place the trellis firmly into the ground. Place the trellis two to three inches behind the bush so that the vines are just touching. Wrap the end of the vine around the trellis and secure very loosely with a piece of florist's wire or a bread tie.
Fertilize your plants soon after planting with a nitrogen based fertilizer. Apply one cup of fertilizer per plant directly to the soil around the tea rose. Rake lightly with a garden rake to distribute the fertilizer throughout the soil.
