Getting a Good Hybrid Tea Rebloom

Getting a good re-bloom from hybrid tea roses

With the first flush of roses nearly over, it's time to do something about getting good blooms for the rest of the season.

Although there are many different varieties and species of roses, most people want their hybrid teas to produce flowers throughout the summer and fall. By their nature, all hybrid tea roses are repeat bloomers. It's in their genes and it isn't hard to get them to flower.

Remember, however, that some hybrid teas also have generosity of bloom in their genetic make-up and others are stingier.

1. Water your roses regularly. No growth can happen without water.

2. Feed your roses a little something every other week during the season. I alternate organic and chemical, always making sure that the roses are hydrated well before I add the fertilizer.

3. Include organic fertilizers and amendments every month. This is especially important if your water comes from wells. During its percolation from rainwater to groundwater its pH level has likely become slightly to significantly alkaline. Organic material in the soil will counteract the alkalinity and allow your rose to absorb more nutrients. Roses love slightly acidic soil at 6.5 pH.

4. Dead-head your hybrid teas as soon as the flowers start to drop petals. That means cut the stem to an outward facing bud eye. Do not allow the rose to develop hips. In many cases, by the time the rose bloom drops petals, the rose has already started to send some growth nutrients to a lower bud eye. Look for a place where a new cane has already started to develop.

5. With the added nutrients, many varieties of hybrid tea produce side buds accompanying each larger bud at the top of a cane. To keep blooms at their best and to increase the blooming cycle, it's important to pull off the side buds early. It seems counter-intuitive but it actually does give you many more perfectly formed flowers. The side buds often cause the terminal bud to be lopsided and the side buds are never as beautiful or as large as the main one. Waiting for the lesser blooms to open just steals time from the plant producing first-class flowers.

With the above five steps followed, the duration from attractive bud to a fully opened rose dropping petals averages around ten days depending on outside temperature, sunshine and variety. Then, in another five to six weeks, you'll have more flowers on that part of the bush. The older and larger the hybrid tea, the more likely it will always been in bloom during the growing period.
