Fertilizing in Fall:
Plants need food too!

Q: I know that I am not supposed to fertilize plants in winter. But I just bought several ground orchids from you, they are blooming now and I wonder if I can give them some food to support their bloom energy? When should I do the last application of fertilizer? I will keep them in a sun room during Winter until Spring.

A: Traditionally, end of October to November is the time when we give the last dose of fertilizer to our tropical plants. Liquid fertilizers, and especially amino-acid based Sunshine Boosters, are safe to apply year around. This means, you can continue feeding your plants with Sunshine Boosters through the Winter without risk of over-feeding or burning roots. Why?
The answer is very simple: even with their metabolism slowed down in Winter, plants will use all that food.
Sunshine Boosters have special mild formulas that are scientifically designed and based on Amino Acids. Plants will use all essential elements from the solution as needed.
Liquid fertilizer is diluted in water, and will be applied only when you water the plant. During Winter, water needs are lowered = watering times are less frequent, with less amount of water = the plants will get less water and less fertilizer accordingly.

Keep in mind that feeding your plants regularly during Winter will help to avoid "winter chlorosis" and other deficiency problems. So called "cool-temperature-induced chlorosis" (CTIC) is especially common in Spring on young, actively growing leaves. Unless chlorosis is prevented by micro-element applications, affected leaves may remain in this condition for the rest of the growing season.

Make sure to select proper type of fertilizer for your over-wintering plants. We have special formulas for foliage, flowering plants, fruit trees, young seedlings, even for for orchids and bromeliads. Check out our selection!
