You can use your greenhouse not just for growing existing plants but also for obtaining a great many new ones, all for free. One way to do this is by propagation using cuttings. Another way is by harvesting seeds. Here’s more on each of these methods. First, let’s look at growing plants from cuttings. In […]
Agapanthus is a genus of perennial plants known for their large, spherical clusters of flowers that bloom well above the foliage on long stems up to two feet above the leaves. The flower color ranges through all shades of blue to a creamy white. At least 20 flowers, and often a great many more, make […]
Living on an island near the coast is interesting in that thunderstorms often fall apart as they pass overhead. This often puts our area in a very dry situation, that, in summer can approach a drought. Being in drought conditions often causes a drop in the island’s only reservoir and the imposition of water restrictions. […]
Dahlias come in many colors, shapes, and sizes, which is a major reason for their popularity. If you’re a fan of huge flowers, you can grow dinner-plate variety dahlias, with blooms up to a foot across. If compact blooms are your preference, you can grow small, pompom dahlias with tight flowers balls only about two […]
A month or two ago, I was watching an English whodunnit and was impressed by the country gardens where the story took place, so I decided that this year I would expand my English country-style flower garden. I purchased seeds for hollyhocks, cleome, rudbeckia, coreopsis, primrose, and columbine and planted them in my basement germination […]
Along with seeds and plants, potting soil has traditionally been one the most expensive items in my gardening budget. I often used several large bales of Pro-Mix BX every year until I finally decided to make my own planting medium. It isn’t difficult to do. The first step is to decide what ingredients you’ll include […]
At this time of year, many greenhouse owners are getting ready to start seeds. I find that pepper seeds take up to three weeks to germinate, so I usually start them first, followed by eggplants, tomatoes, and flowers. However, there’s a problem starting heat-loving plants in a small greenhouse in late winter. The seeds of […]
Have You Checked Your Soil pH Lately? You probably don’t think much about it, but the pH of your soil – its acidity or alkalinity – can matter greatly to how well your plants grow. And what many gardeners don’t realize is that they can be inadvertently altering soil pH every time they water their […]
This year my wood-framed greenhouse needed repairs after several big storms, including a hurricane, as well as 40 years of constant use. It leaked and required some serious attention. In fact, in one area the wood had rotted to such an extent that I could push a finger through it. This highlights the problems with […]
Stores full of beautifully mounded chrysanthemums is a sign that fall is arriving. If you buy some of these mums for a colorful fall display, you shouldn’t just toss them out when the flowers fade. Greenhouse owners can easily keep these plants going and also propagate more of them. Here’s how. First, you should know […]
Keeping records of what goes on in a greenhouse can be an enormous help. It’s how I’ve learned precisely when to start my vegetable and flower seeds, as well as which potting medium and lighting conditions will give optimal germination and growth. From looking at my records, for example, I know that I get the […]
During summer, greenhouse plants need a lot of attention. Temperatures inside a greenhouse can easily soar to over 100oF (38oC) even with all the windows and doors open. Such heat can significantly stress your plants. The problem with high heat is that it causes water in plants to get quickly depleted through transpiration. Transpiration is […]
