The temperature in a root cellar is always a compromise. It’s never equal in all parts of the cellar. Most vegetables never get the perfect temperature.
The temperature near the ceiling of many root cellars can sometimes be 10° F. or so higher than near the floor. This variance creates temperature zones in the root cellar. Your vegetables will keep better if you understand the temperature zones of your root cellar and store crops accordingly. Read the rest of this entry »
Trees which do not shed layers of dead tissues regularly have increasingly rugged bark as they age. This can often be observed by noting the relatively smooth nature of the top of a trunk in comparison with the older parts at the bottom. With age, the pressure from within causes the surface to crack and the resulting deep fissures are typical of many trees. The way trees develop such features can be diagnostic and one of the most distinctive is the Sweet Chestnut (Caslanea saliva) which usually cracks in spirals. Read the rest of this entry »
Generally, however, the vascular bundles in a straight piece of grass stem — Maize (Zea mays) being a good example — do not run parallel to the sides but weave from the inner part of the stem to the outer, returning inwards after the leaf traces have branched off. So the vascular tissue forms a series of spirals through the stem. As well as having a different arrangement in the stem, these vascular bundles are different in their individual make-up, there being no layer of cambium between the xylem and the phloem. This means that they cannot develop a woody, strengthening tissue as can dicotyledonous plants. There are exceptions, however, as in the palms and allied woody-stemmed monocotyledons.

The leaves fall to form a deep carpet beneath the trees, adding to the dead twigs, flowers and unripe fruit remnants already there. Every year trees shed more than 3,000 kg of waste products in every hectare of woodland and all this breaks down, together with the herbs of the forest floor to form a deep layer of litter. As this litter breaks down so the minerals and other organic substances which were stored in the leaves are released once more, and the resulting layer of humus acts as a natural fertilizer.

Dodder is perhaps one of the most interesting of the total parasites. It starts its existence normally, the seed germinating and producing a club-shaped taproot which fixes the plant in the soil. The shoot then begins growing, not straight up as is usual in seedlings, but with a circular movement. As soon as it touches a support it encircles it. If, however, the stem fails to find a suitable plant nearby, it is not rigid enough to grow upright and falls back to the ground. Read the rest of this entry »
The land surface of our planet provides a remarkably wide range of climatic conditions, and all but the most inhospitable habitats have been colonized by plants. Where plants are established, insects and animals can follow and the greatest diversity of life of all kinds is to be found in the most ideal climates. Read the rest of this entry »
A thriving row of cauliflower is a spectacular sight in the vegetable garden, but few people think they can have great success with it. I think it’s as easy to grow as any cabbage family crop. Cauliflower is less tolerant to hot weather than its relatives, though, so it’s important to set your plants out very early or plan on a fall crop. If the heads mature in the heat, they’re apt to have a bitter taste or go by very quickly.
For your first crop, set out some plants 3 or 4 weeks before the average date of the last spring frost. Pinch off a couple of the lower leaves.
As cauliflower heads get to be 4 to 5 inches across, they should be blanched by preventing sunlight from reaching the heads. Read the rest of this entry »
It’s exciting to discover the first thumb-sized broccoli heads in the row and watch them grow. Sometimes they’ll get to be 6 or 8 inches wide at the top. Other times the heads will be quite small when it’s time to pick them.
The center head must be cut before it blossoms, even if it’s on the small side. How do you tell when the head is ready to blossom? A head of broccoli is a cluster of flower buds. When the head is young, its individual buds are packed very tightly. Rub your thumb over them and you will feel that tightness. As long as the buds stay tight, let the head grow. But when the buds loosen up and spread out, they are about to pop up and produce little yellow flowers. Again, pass your thumb across the top of the head—if the buds are loose, you’d better harvest.

Everybody has a favorite way of growing their prized tomatoes. My way is to support them with cages. After many years of experimenting, I’ve settled on caging as the easiest and best way to care for tomatoes. Tomato plants support themselves easily inside a cage. Because they receive very little pruning, they grow enough leaves to shade the tomatoes. This protects them from sunscald and helps them ripen evenly. Read the rest of this entry »
Squirrels and chipmunks are fun to watch, but they are the hardest to keep away from your corn and sunflowers. A fence won’t keep them out, not even an electric one. They jump so well and scurry into the garden so fast that an electric shock doesn’t stop them. They’re in the garden while they’re still feeling the zap.
In the sweet corn or popcorn rows, squirrels climb right up the stalks and eat the ears. They’re smart. Often they only work the inside rows so you won’t notice them. A few times I have seen squirrels trying to haul away whole ears of corn. In a row of sunflowers they can jump from one stalk to the next as if they were in a tree.
In a small garden you may be able to use old stockings or heesecloth on the sunflower heads and corn ears to foil the squirrels at harvest time. In a big garden, an active cat or an eager dog may be your only hope. Read the rest of this entry »
Digging is usually necessary to incorporate bulky organic materials, relieve compaction, improve drainage, improve soil texture and control growth of weeds.
Inadequate soil preparation before planting or sowing is a major cause of horticultural disappointment. Digging and the application of fertilizers and bulky organic materials are usually necessary to ensure that the soil is suited to the plants or crops that you want to grow. Drainage may also be required.
There are certain fertilizers that supply all three of the principal foods required by plants: nitrogen for leaf and stem growth; phosphorus for good root growth; potassium (potash), which helps to form and ripen flowers, fruits and seeds.
Raising your own plants is much cheaper than buying from a nursery or garden centre. Although a greenhouse is helpful if you want to raise tender plants, a cold frame also has plenty of possibilities for propagating plants.
Apart from a greenhouse and cold frame, there are various other tools and materials which you will find useful for the successful propagation of plants.
Virtually all shrubs can be propagated in this way. The following respond particularly well.
Success with this method depends upon providing the right conditions. Warmth and humidity are essential for good results in every case.
Pruning roses will not reward you with more flowers nextyear. However, it will control shape and maintain health. Wild (species) roses and hybrid shrub roses need no pruning — just the removal of dead wood.
If money is no object you can now have a greenhouse or conservatory that looks after itself, with the plants watered automatically. On a more modest scale, garden frames and cloches are extremely useful (andcomparatively inexpensive) pieces of equipment: they are of particular value on the vegetable plot for extending the growing season at either end.
Today greenhouses come in all shapes and sizes to suit every need and site.
Birds usually create the biggest problem, but you should look out too for mites and weevils.
Climbing roses will grow in tubs. Choose climbers rather than ramblers, as climbers grow more circumspectly and are less prone to mildew and other problems. The list is endless, but I would not like to be without ‘Zephyrine Drouhin’, despite her tendency to mildew, ‘Handel’, which is cream with rosy pink edges and has handsome bronze foliage, or ‘Maigold’, which is double yellow and beautifully scented. Some roses will flourish only on south walls while others are happy in a west or east aspect and others will even tolerate a north wall. Then there are those that are scented and those that are not, those that have one magnificent flowering and then call it a day and others that flower less prolifically but throughout the summer.

In the open garden autumn is a time of cutting down, tidying up and battening down the hatches against the onslaught of winter. In the more restricted garden on the window sill there is a little more scope for planting, to provide interest and perhaps colour for the grey days to follow. It is the greyness of the days, and hence the lack of light, rather than the cold that makes the late autumn and winter such a dead season as far as flowers are concerned.
For early autumn you must have dahlias. Their paint-box colours are quietened by the softer light of autumn and dahlia blooms laced with cobwebs and beaded with dew are, for me, a final confirmation that summer is truly over. Read the rest of this entry »
