Chlorosis in Plants – Is it Iron Deficiency?

I just got my favorite gardening magazine and a reader asked the question, “The leaves of my roses are yellowing but the veins are green. What causes this?” The given answer is, “This is called chlorosis and is caused by a deficiency of iron”. The answer might be true, or it might not be true. It is certainly an incorrect statement. Find out the truth about chlorosis.

Snowdrop – Should They be Transplanted ‘in the Green’?

Snowdrop, Galanthus nivalis and other Galanthus species, are one of the best spring flowering plants. The common advice given for transplanting them is that it should be done ‘in the green’. Transplanting in the green means transplanting snowdrops right after flowering, while the leaves are still green.

I suspect that this myth has been handed down for many generations, but it is not based on fact. Lets have a closer look.

Pruning Shrubs at the Right Time

The standard advice is to prune spring flowering shrubs right after flowering and to prune summer flowering shrubs in winter or early spring. Is this the best advice?

Pruning spring flowering shrubs after flowering ensures that the shrub has time to develop next yearโ€™s flower buds. Summer flowering shrubs develop flower buds in spring on new wood so they are pruned before flower buds are formed. This is not bad advice for maximizing flower production, but is it the best advice for the vigor of the shrub?

Fish Fertilizer – Is it Worth Buying?

Fish fertilizer is very popular. It is reported to be a good source of nutrients and a good source of proteins, amino acids, and oilsโ€”for your plants. Can plants use fish proteins and oils? Is fish fertilizer a good source of nutrients?

Before I go any further, let me say that there is nothing wrong with using fish fertilizer. It will help make your plants grow. I have two problems with fish fertilizer: it is extremely expensive compared to other sources of fertilizer, and many of the claims for it have no basis.
