Watering and humidity

Watering in the greenhouse is an essential activity about which there is much disagreement. Some plants prefer a constant moisture, while others are believed to prefer to become rather dry before being watered. In practice the majority will adapt fairly readily to any steady regime that does not keep them sodden or allow them to dry out enough to begin to wilt. It is, however, a golden rule when watering by hand either to give enough water to moisten all the soil in the pot or to refrain from...

Specialisation

In earlier chapters 1 have mentioned some of the favourite flowering plants that often capture the whole attention of amateurs. Perpetual flowering carnations, chrysanthemums, fuchsias and the various pelargoniums are all attractive plants with long flowering seasons that respond well to skilled cultivation. Each one of them can become an absorbing hobby. Many people find it more satisfying to know a great deal about a limited subject than to have a smattering of knowledge over a wide field....

Plants from cuttings

The greenhouse favourites grown from cuttings are in themselves enough to keep every greenhouse full of bloom all the year round, as well as providing a special hobby for a wide variety of people. The actual process of taking cuttings has been revolutionised in recent years for the less skilled. Hormone rooting powders hasten rooting and make difficult species easier to strike, while the plastic bag has created a simple way of ensuring a moist environment for a potful of cuttings until rooting...

Plants from seed

Sowing tiny seeds and watching the whoie process develop, no matter how long it takes, is a never-ending pleasure to those who become deeply involved in gardening. At the same time there is nothing more maddening than careful sowing, a long wait, and then no results. Many of us will never attempt to acquire the right mental attitude to raise rare shrubs or difficult alpines from seed. But there is room for all tastes in the greenhouse and a wide variety of reliable seeds will give rapid and...

Diseases

This disease is caused by several different soil and water-borne fungi which cause the collapse of seedlings at ground level. It is most troublesome where seedlings are overcrowded, overwatered, or grown in unsterilized compost or watered with water from a dirty tank or butt. Prevent infection therefore, by sowing seeds in sterilized compost and by watering carefully with clean water, Foot rot, Crown rot and Root rot. May be caused by the same fungi as those causing damping-off and...

Foliage plants

In the confined space of the small greenhouse all foliage is important. Even flowering plants with large coarse leaves are unlikely to be worth growing. No one should ignore foliage plants, for they are attractive all the year while many flowers only last a short time. They are helpful, too. in avoiding the flat effect of many small pot plants grown on one level, for there are trailers, trees, and palms, as well as the ferns and other shade lovers that grow happily under the staging. Flower...

Hch Insecticides For Eggs In Bonsai Soil

No matter what views one may hold about pests and diseases or poison sprays, the golden rule under glass is to start clean. With the new greenhouse there is no problem, but in the year-round warmth of heated greenhouses there is bound to be a gradual build up of unwanted guests unless preventive steps are taken. Some may be engaged in eating others and there is much talk of preserving beneficial predators and parasites. We want to prevent pests or diseases from consuming or disfiguring our...
