Lazy gardener: Why your flowers won't bloom
Why aren't my flowers blooming?If you're watering every day, cut back.Group these with like plants, not with flowers that need regular watering.Tomatoes and most grafted roses require all-day sun to produce fruit or flowers.• Bud damage.If you leave spent blooms on and seed develops, the plant will stop flowering.Pruning at the wrong time might result in buds being cut off.Prune spring bloomers such as azaleas immediately after they bloom, because they soon start setting next year's buds.Boost soil nutrients with compost or a balanced fertilizer.Phosphorus promotes flowering.Coffee grounds and banana peels worked into the soil may also help.Amaryllis and daylilies are among the plants that stop blooming if overcrowded.• Plant damage/stress.Beating larger shrubs with a broom (preferably at night when the neighbors can't see you) may trigger blooming by forcing sap movement. .

How to Grow Black-Eyed Susan Flowers
I dig this kind of rough and tumble adventure, partly because so much of it is spent outdoors, leaving me exposed to the elements.My eyes were peeled, scanning the roadsides and the fields, the highway medians and the drainage ditches, searching for flowers and plants that I could identify.Lest you think poor R. hirta got in a bar fight and wound up with a contusion to her ocular space, let’s set the record straight:.Black-eyed Susan is named not because of a propensity to fight other plants, but because of her dark central cone that is surrounded by brightly colored, petal-like rays.Part of their widespread distribution is due to their eagerness to spring up from seed, but their iconic appeal doesn’t hurt either.Throw in their willingness to grow just about anywhere there’s sunshine and a checklist of beneficial aspects, and you’ve got a nice plant for any landscape.The state flower of Maryland, black-eyed Susan has a mounding habit, growing to 2 to 3 feet tall, and can be annual, perennial, or biennial, depending on the variety and where it is grown.This guy deserved to at least have a flower named after him; when his home was burning down in 1702, the 71-year-old was standing on the rooftop of a nearby building, shouting orders to the town citizens extinguishing the flames.The roots have been boiled and strained to aid in treating colds and intestinal worms (yuck), while the dried flowers can be used in much the same way.And just as humans enjoy the beautiful, bold flowers, butterflies, bees, and other beneficial insects are also attracted to R. hirta.You’ll also spot sparrows, cardinals, nuthatches, and my personal favorite, the chickadee, devouring these seeds.The poor land daisy is of vital importance to local environments and is an absolute necessity in any pollinator garden.If stretches of your property that fit the minimal needs of this flower are available for planting, then give it a shot en masse.It’s suggested to wait until well after the cold weather is gone for the season before directly sowing seeds outdoors, ideally when the soil temperature has reached about 70°F.A few coworkers have told me that their own directly sown seeds take a year before they bloom, and they are trustworthy folks.I wouldn’t know because I can be a tad impatient and tend to sow my seeds a bit earlier than I’m supposed to… but I can certainly attest to Rubeckia’s aversion to frost and cold!A thriving root system typically reaches depths of six feet or more, and they are far happier when in the ground than in almost any container.Many gardeners find this plant to be quite resilient and able to be grown in most any condition, including salty soils, making them a good addition to coastal landscapes.I favor the properties where the seeds are free to go wild, but not every homeowner sees an informally planted swath of black-eyed Susans as desirable.In this case, gardeners will want to remove the seed heads before the flowers dry completely in late summer or fall.I tend to leave my perennials standing over the winter for a variety of reasons, and black-eyed Susans respond well to this kind of treatment.Companion plants for this garden favorite are almost too many to list, but a few ready and reliable choices include zinnias, globe thistle, sedum, perennial hibiscus, echinacea, joe-pye weed, and ornamental grasses.The yellow and golden colors look nice near shrubs with darker foliage, like smokebush and elderberry.If you move around a fair bit like I do, having a trustworthy flowering friend that can follow you almost anywhere is the next best thing to keeping a permanent garden.Try the stunning African daisy, a great annual with a variety of colors to choose from, and don’t forget about the awesome landscape grasses that are a match made in heaven for black-eyed Susans.Product photos via Garden Safe, Safer Brand, Outsidepride, Nature Hills Nursery, and True Leaf Market. .
